<h1>Community-Based Learning</h1>

<p class=3DMsoNormal>This very special (and final) issue of the <i
style=3D'mso-bidi-font-style:normal'>ACM SIGGROUP Bulletin</i> presents pro=
ducts
of a workshop on <i style=3D'mso-bidi-font-style:normal'>Community-Based
Learning: Explorations into Theoretical Groundings, Empirical Findings and
Computer Support</i> that was held at the International Conference of the
Learning Sciences (ICLS 2004). </p>

<p class=3DMsoNormal>The workshop generated considerable enthusiasm and a p=
alpable
sense that the participants were heading in a strikingly (and surprisingly)
similar direction that was important to the future of the larger research
community. Individuals came to the workshop with brief position papers that=
 had
been shared on a pre-workshop website. In the day-long discourse, themes
surfaced, became explicit and developed; they created a sense of shared
knowledge building that was directly relevant to the individual contributio=
ns
that people had brought with them. Perhaps the most productive time of the
workshop was a period when smaller workgroups were formed to brainstorm
specific aspects of the day&#8217;s theme. During subsequent days of the
conference, as part of the preparation of this publication and through
circumstances of life in the research community, workshop participants
interacted further with each other in many combinations. The papers being
published now are knowledge artifacts that reflect and encapsulate what the
workshop community learned, as re-formulated from within the scientific
perspectives of individual authors.</p>

<p class=3DMsoNormal>Contributions to the workshop aimed to better understa=
nd
learning within diverse educational communities and to explore their potent=
ial
support by means of community-based technologies. Workshop discussions focu=
sed
on intersections and relationships between educational research and computer
science as applied within the learning sciences. Although the papers below =
are
grouped into sections on theoretical groundings, empirical findings and com=
puter
supports, almost all of the contributions actually span the three focal are=
as.
The theory reflects practical experiences, at various levels of abstraction.
The empirical inquiries involve computer-supported learning and explore rel=
ated
theoretical issues. The computer support investigates technologies that are
motivated by theoretical stances or questions, and they try these technolog=
ies
out in practical settings.</p>

<p class=3DMsoNormal>The premise of the workshop was that the learning scie=
nces
need to better understand theoretical, empirical and technical aspects of
community-based learning, in their interactions in concrete settings. New
computer systems need to take into account the complex needs of educational
communities, which typically change dynamically, are emergent, evolve over =
long
periods of time, and allow multiple interacting memberships. While
socio-cultural and related theories recognize these features on a theoretic=
al
level [1; 2; 9; 16; 17], empirical research results focus on diverse learni=
ng
communities and aim to draw design implications for technological support [=
3;
4; 11; 13].</p>

<p class=3DMsoNormal>The design of tools for supporting learning in schools=
 and
universities has too often neglected the notion of community. Most educatio=
nal
technology still focuses on supporting the individual learner or the
traditional role of the classroom teacher [10; 12; 14; 15]. Individual clas=
ses
are seen as the focus of activity, where the class is seen as a set of
individuals rather than as a community structure having relations with other
classes and situated within the cultural communities where the students are
rooted. Some recent computer systems have shifted their focus from supporti=
ng
individual learners or teachers to supporting group work [5-8]. This does n=
ot
solve all the problems when it comes to supporting the creation of a learni=
ng
community, where learners contribute and build on other people&#8217;s
experience, combining different perspectives across classes, direction of s=
tudy
and diverse cultures. Most existing systems fail to acknowledge that knowle=
dge
is not just an asset of the individual, but rather of the group and the
community as a whole.</p>

<p class=3DMsoNormal>The notion of community-based learning is particularly
indebted to the concept of &#8220;community-of-practice&#8221; (CoP).
Popularized in Lave and Wenger&#8217;s <i style=3D'mso-bidi-font-style:norm=
al'>Situated
Learning</i> [9] and their other publications, this concept was forged in s=
mall
workgroups within a vibrant research community in the late 1980&#8217;s that
included the <st1:PlaceType w:st=3D"on">Institute</st1:PlaceType> of <st1:P=
laceName
w:st=3D"on">Research</st1:PlaceName> in Learning in <st1:place w:st=3D"on">=
<st1:City
 w:st=3D"on">Palo Alto</st1:City></st1:place> as well as participants from =
Xerox
PARC, Berkeley and UCSD. Fifteen years later, it is high time that this
influential concept be reflected on critically, not in order to dismiss its
importance but to extend its applicability while recognizing its limitations
and variations. This special issue reflects the view that innovative insigh=
ts
like the CoP concept emerge from small group discourses and are subsequently
adopted by larger communities. The small groups and the larger communities =
can
take on many forms, resulting in a variety of ways in which knowledge build=
ing
and learning take place within them.</p>

<p class=3DMsoNormal>It is perhaps fitting that these workshop papers&#8212=
;which
respectfully critique the concept of CoP and point to the role of groups wi=
thin
the CoP&#8212;be published as a final act of ACM&#8217;s special interest g=
roup
for software support for groups. Taken together, the contributions to this
issue suggest the importance of a theoretical, empirical and design focus on
the group&#8212;on small groups within communities. They thus propose a ren=
ewed
concern with the group within the research communities of CSCW and CSCL, wh=
ich
will carry forward the SIGGROUP mission.</p>

<h1>Theoretical Grounding </h1>

<p class=3DMsoNormal>Although the title of the workshop and of this issue r=
efers
to the concept of community-based learning, it may be preferable to use the
broader term &#8220;computer-supported collaborative learning&#8221; (CSCL)
because the presented concepts, approaches and studies reflect learning
processes that are characterized by the following three dimensions: </p>

<ul style=3D'margin-top:0in' type=3Ddisc>
 <li class=3DMsoNormal style=3D'mso-list:l8 level1 lfo2;tab-stops:list .5in=
'>collective
     (or collaborative) knowledge building and learning </li>
 <li class=3DMsoNormal style=3D'mso-list:l8 level1 lfo2;tab-stops:list .5in=
'>technologically
     supported learning or learning with and about technological media</li>
 <li class=3DMsoNormal style=3D'mso-list:l8 level1 lfo2;tab-stops:list .5in=
'>learning
     across geographical distance by means of digital networks</li>
</ul>

<p class=3DMsoNormal>Most of the contributions are founded on socio-cultura=
l and
constructivist learning theories and focus on the concept of communities, e=
.g.,
as communities of practice, communities of interest, learning communities,
knowledge-building communities. However, a terminological concentration on
&#8220;community-based learning&#8221; could neglect the relevance of techn=
ological
support and spatial distribution. The notion of CSCL offers a broader
understanding of technologically mediated collective learning processes tha=
t is
more appropriate for this collection of research studies, which questions t=
he
nature of community. The theoretical contributions actually enhance our
understanding of the importance of community to learning by differentiating
various structural levels of community and different kinds of learning
communities.</p>

<p class=3DMsoNormal>The tone of critiquing the notion of community was set=
 by
the workshop facilitator, who argued for a methodological focus on small gr=
oups
within communities. The role of small groups as the locus of group cognitio=
n is
presented in <b style=3D'mso-bidi-font-weight:normal'>Gerry Stahl</b>&#8217=
;s
paper as the site where knowledge building can most likely take place in
communities. Looking at the spectrum between individualistic and social
concepts of learning in communities, he argues for an analytical perspective
focused on the intermediate level of small work groups within larger
communities. Stahl reflects on individual and social psychological concepts=
 of
individual and group cognition, and the mediation of cognitive processes by=
 the
social context in which the individual or the group might be situated. He a=
lso
examines the mediation of individual and group cognition by technological
media. With regard to his own experiences and to others&#8217; research on
knowledge building in collaborative working and learning settings, Stahl dr=
aws
the conclusion that &#8220;small groups are the engines of knowledge buildi=
ng,&#8221;
creating the basis for both individual internalization and collective
externalization of knowledge in cultural artifacts and procedures of social
communities. The idea of looking at communities as structured by productive
small groups reappears in many of the other contributions.</p>

<p class=3DMsoNormal>A small group at the workshop took up the terminologic=
al
issues raised by talking about small groups within communities. <b
style=3D'mso-bidi-font-weight:normal'>Markus Rohde and David W. Shaffer</b>
volunteered to write up the brainstorming that took place in this workshop
group and to develop the ideas further. In their report, they analyze a var=
iety
of terms and concepts to describe collections of people involved in
group-learning activities. They discuss meanings and connotations of terms =
like
&#8220;group,&#8221; (&#8220;small group,&#8221; &#8220;working group,&#822=
1;
etc.), &#8220;collective,&#8221; &#8220;network&#8221; and
&#8220;community.&#8221; Furthermore, they reflect on different modes,
components and mechanisms of interaction and social perception (e.g.,
collaboration, culture, identity, history) that are crucial for most studie=
s on
community learning. Rohde and Shaffer present a first step to a
framework&#8212;from group to community&#8212;and conclude that there shoul=
d be
different requirements for tools aiming to support collaborative learning a=
nd
for research methodologies with regard to different kinds of collectives.</=
p>

<p class=3DMsoNormal><b style=3D'mso-bidi-font-weight:normal'>Lachlan Forsy=
th and
Lynette Schaverien</b> present a model of collective learning for online
learning (and teaching) communities. Based on their findings in educational
research, the authors introduce a generative theory of learning and discuss
implications of neuroscience and evolutionary psychology for the analysis of
collective learning. The generative theory approach understands learning as=
 the
cyclic generation and testing of ideas in order to better the chances of su=
rvival
of an organism, individual or group/culture. The generative model of collec=
tive
learning analyzes six different acts of learning as collective or emergent
phenomena. Forsyth and Schaverien name as topics for future research the
adoption of models for the description of processes of enculturation and
collective intentionality and the description of appropriate technologically
rich environments for support of collective learning.</p>

<p class=3DMsoNormal><b style=3D'mso-bidi-font-weight:normal'>Liz Charles <=
/b>presents
a description of an active classroom enacting a learning-by-design curricul=
um
involving workgroups learning science through design projects. She asks how=
 one
can analyze the cognitive and social interactions that take place within or
between the levels of individual, small group and larger classroom communit=
y.
In particular, she explores the applicability of dynamic systems theories t=
hat
have been so successful in the physical and biological sciences. She propos=
es
combining a particular flavor of complex dynamic systems theory with a focu=
s on
timescales and history in order to capture flows of activity. Charles appli=
es
this framework to the classroom description that she started with and comes=
 up
with two views of the classroom scenario. Not only is she able to capture t=
he
relationships of individuals and artifacts to the small group that defines
their activity structure, but she also represents change in time. <b
style=3D'mso-bidi-font-weight:normal'><o:p></o:p></b></p>

<p class=3DMsoNormal>A contribution from <b style=3D'mso-bidi-font-weight:n=
ormal'>David
W. Shaffer</b> focuses on the concept of &#8220;pedagogical praxis&#8221; a=
s a
fundamentally different approach to describe and investigate communities of
practice in educational settings. Based on the understanding that different
professional practices can be characterized by distinct and coherent
&#8220;epistemic frames,&#8221; Shaffer posits that for the design of learn=
ing
environments, a pedagogical praxis of professional trainers that take a
learning practices perspective might be of greater importance than the
real-world activities of professional experts. Thus, it is not what experts=
 <i
style=3D'mso-bidi-font-style:normal'>do </i>in their everyday practice that
should be the basis for practice-oriented teaching, but what <i
style=3D'mso-bidi-font-style:normal'>learners</i> <i style=3D'mso-bidi-font=
-style:
normal'>do to</i> <i style=3D'mso-bidi-font-style:normal'>become</i> <i
style=3D'mso-bidi-font-style:normal'>experts</i> that should be the focus. =
This
means that pedagogical praxis as a means to create comprehensive learning
environments is not a striving for &#8220;real&#8221; practice situations, =
but
for &#8220;thickly authentic&#8221; ones.</p>

<h1>Empirical Findings</h1>

<p class=3DMsoNormal>The papers in this volume present a wide range of case
studies of computer-supported community-based learning, referring to primary
school pupils and students in university settings; to students in school and
out of school in after school programs, community centers or professional
internships; to student teachers and other professionals; to people learning
and instructing online, face-to-face or in blended hybrid arrangements.
Therefore, the studies offer a spectrum of applications of collective learn=
ing
environments, reaching from traditional educational institutions to
community-based or technology-based experimental facilities. Moreover, the
studies presented include global experiences from different countries and
regions: American, Australian and European.</p>

<p class=3DMsoNormal><b style=3D'mso-bidi-font-weight:normal'>Joyce Yukawa<=
/b>
reports on her experiences with co-reflection in dyadic interaction during =
an
online course in action research. She analyzes and compares her chat-based
communication with two students according to processes of collaborative
reflection between teacher and student. Yukawa looks upon this co-reflectio=
n as
a core activity of group cognition. Despite the fact that group cognition is
more difficult to analyze in dyadic interaction than in group interaction, =
she
concludes that in her online communication with students the co-constructio=
n of
knowledge occurred, and she reflects about her role as teacher, facilitator,
coach, mentor and even co-learner.</p>

<p class=3DMsoNormal>The community of practice of philosophers of science (=
PoS)
is the starting point of <b style=3D'mso-bidi-font-weight:normal'>Johannes =
Strobel</b>&#8217;s
deliberations in &#8220;Communities of Reflection-Practice.&#8221; Aside fr=
om
disciplines such as engineering, biology and physics, most humanities scien=
ces
do not have an established, well-defined professional practice outside the
university. Therefore, scholars, teachers and students of PoS face
methodological difficulties building communities of practice with experts
outside their educational setting, collaborating on real-world tasks, and
learning from these experiences. With regard to this lack of a well-structu=
red
real-world practice, Strobel calls these communities of (mostly humanities)
scientists &#8220;communities of reflection-practice.&#8221; He discusses h=
ow
modern socio-cultural and constructivist learning theories and approaches c=
ould
be made fruitful educational environments for these research areas. Another
question addressed by the author is the multi-disciplinary nature of PoS and
similar sciences: Strobel reflects on possible clashes of different
disciplines&#8217; communities of practice running up against each other in
multi-discipline research areas.</p>

<p class=3DMsoNormal>Like Strobel in his contribution, <b style=3D'mso-bidi=
-font-weight:
normal'>Ralf Klamma and Marc Spaniol</b> are investigating communities of
practice within the humanities. Their case study presents the <st1:place w:=
st=3D"on"><st1:City
 w:st=3D"on">MECCA</st1:City></st1:place> project, which aims to support a
community within film studies. This project is run by the interdisciplinary
research center &#8220;Media and Cultural Communication&#8221; and aims to
support members of different scientific disciplines (film studies, history =
of
art, graphical design, etc.) who are researching facial semantics in movies.
Klamma and Spaniol discuss, on an empirical basis, potential
&#8220;clashes&#8221; of different disciplines that come together in a rese=
arch
community. These clashes concern different perspectives, distinct vocabular=
ies
and alternate classification schemes. These ontological differences require=
 a
concept of &#8220;semantic freedom&#8221; and &#8220;fluid archives.&#8221;=
</p>

<p class=3DMsoNormal><b style=3D'mso-bidi-font-weight:normal'>Ralf Klamma, =
Markus
Rohde and Volker Wulf</b> discuss experiences with a longitudinal study of =
the
course &#8220;High-tech Entrepreneurship and New Media.&#8221; The course
design is based on socio-cultural theories of learning, and considers the r=
ole
of social capital in entrepreneurial networks. By integrating student teams
into the communities of practice of local start-ups, the course offers lear=
ning
opportunities to students, companies and academia. The student teams are
connected to each other and to their supervisors in academia, and practice
through a community system. Moreover, the course is accompanied by a series=
 of
lectures and group discussions that include extra-academic experts and peop=
le
with start-up company experience. </p>

<p class=3DMsoNormal><b style=3D'mso-bidi-font-weight:normal'>Gunnar Steven=
s,
Michael Veith and Volker Wulf</b> discuss a project aimed at fostering
integrative community processes by deploying computer facilities to German =
and
immigrant primary school children and their parents. Influenced by the
MIT-approach of Computer Clubhouses, the authors introduced a computer lab,=
 an
interactive course design and a primarily volunteer-based facilitator/coach=
ing
concept to German students and Turkish immigrant pupils in <st1:place w:st=
=3D"on"><st1:City
 w:st=3D"on">Bonn</st1:City>, <st1:country-region w:st=3D"on">Germany</st1:=

By integrating pupils and their parents and by explicitly inviting Turkish
immigrant and German families to their &#8220;Come_IN club,&#8221; Stevens =
et
al. aim to foster integrative processes in the multi-cultural neighbourhood=
. By
collaboration in cross-cultural and multi-generation project groups and on
personally relevant tasks (e.g., the creation of multi-media family histori=
es),
cross-community building and intercultural learning should be established. =
The
attractiveness of computer technologies is expected to play a role as a
motivational factor and as an &#8220;entrance card&#8221; into the immigrant
community. The authors present first findings of this ongoing project,
indicating a very strong interest and involvement of the target groups.</p>

<h1>Computer Support</h1>

<p class=3DMsoNormal>The papers in this section explicitly take up issues of
technology by experimenting in specific situated contexts of community
learning.</p>

<p class=3DMsoNormal><b style=3D'mso-bidi-font-weight:normal'>Thierry Iscki=

Charles Delalonde</b> present a case study of an online course for MIS stud=

The authors evaluate course design and technological support with observati=

Excel. Their findings show evidence of an inefficient use of discussion for=
ums
and the absence of an effective (online) learning community. Isckia and
Delalonde end up with several recommendations for improved course design and
some rules for more efficient online interaction.</p>

<p class=3DMsoNormal>In his case study of a blended learning university cou=

 and
to reduce travel and organization costs, the university offered three modes=
 of
participation in the course: attendance in the in-class meeting with the
teacher on a local campus, attendance in another classroom with other stude=
nts
to which the lecture was broadcast online using video-conferencing, and
following the lecture online with videoconferencing from home offices. This
educational setting is called a &#8220;blended instructional delivery
method&#8221; and it was evaluated by observations in the classrooms and
interviews with participants. The main findings demonstrate evidence for the
relevance of social presence and information richness of the learning
environment. The blended instructional delivery method proved to be a promi=
sing
learning environment, even for situations in which physical presence is not
possible.</p>

<p class=3DMsoNormal>As described by <b style=3D'mso-bidi-font-weight:norma=
l'>Amon
Millner</b>, the Hook-ups initiative gets children and youth in community
technology centers (such as local computer clubhouses) engaged in the
development of so-called &#8220;Hook-ups.&#8221; Hook-ups are physical obje=
cts
(like joysticks, toys, every-day artifacts, tools such as scissors, etc.) t=
hat
work as human-computer interfaces by controlling games, animations and other
computer programs. Based on the constructionist theory of learning and on t=
he
approach of &#8220;learning through design,&#8221; ten 18-year-old youths w=
ere
motivated to play with computers (digital devices) and everyday objects with
which they are familiar (physical devices), and create Hook-ups by using
sensors, wires and a specific kind of a Hook-up interface board to connect =
them
to each other and develop computer programs (by &#8220;simple scratch&#8221;
programming) that can be influenced by manipulation of the physical objects.
Millner presents some illustrative examples that give evidence for the succ=
ess
of these Hook-ups projects.</p>

science, math and technology. A first evaluation of a so-called &#8220;virt=

<h1>1. mediation of group cognition</h1>

<p class=3DMsoNormal>The term &#8220;community-based learning&#8221; can re=
fer to
a variety of forms of learning. One can, for instance, insist on an
individualistic notion of learning and argue that individual learning can be
enhanced by factors that may influence it from a supportive community
environment. At the other theoretical extreme, one can propose a social
conception of learning and claim that most important knowledge building tak=
es
place at the community level, while individual learning is a secondary matt=
er
of internalization, acculturation or increased participation in community.
Here, we will stake out a middle ground: that community-based learning shou=
ld
be analyzed at the intermediate level of small groups of individuals within=
 the
community.<a style=3D'mso-footnote-id:ftn1' href=3D"#_ftn1" name=3D"_ftnref=

We point out that small groups typically mediate the relationship of
communities to their members and we propose a consideration of small group
cognition as an alternative methodological focus to either cognition in the
head of individuals or the cultural knowledge of a whole community. This
approach has practical implications for CSCL and CSCW: collaboration is tak=
en
to be a potential emergent phenomenon of small group interaction, and the
computer support of collaboration is analyzed as an enabling technology who=
se
design and use forms and transforms the nature of the interactions.</p>

<p class=3DMsoNormal>Let us consider this article&#8217;s title a word at a=
 time.
<i style=3D'mso-bidi-font-style:normal'>Mediation</i> is the most complex a=
nd
unfamiliar term. In popular and legal usage, it might refer to the interven=
tion
of a third party to resolve a dispute between two people. In philosophy, it=
 is
related to <i style=3D'mso-bidi-font-style:normal'>media</i>, <i
style=3D'mso-bidi-font-style:normal'>middle</i> and <i style=3D'mso-bidi-fo=
nt-style:
normal'>intermediate</i>. So in CSCL or CSCW, we can say that a software
environment provides a <i style=3D'mso-bidi-font-style:normal'>medium</i> f=
or
collaboration or that it plays an <i style=3D'mso-bidi-font-style:normal'>i=
ntermediate</i>
role in the <i style=3D'mso-bidi-font-style:normal'>midst</i> of the
collaborators. The contact between the collaborators is not direct or <i
style=3D'mso-bidi-font-style:normal'>im-mediate</i>, but is <i style=3D'mso=
-bidi-font-style:
normal'>mediated</i> by the software. Recognizing that when human interacti=
on
takes place through a technological medium the technical characteristics
influence&#8212;or <i style=3D'mso-bidi-font-style:normal'>mediate</i>&#821=
2;the
nature of the interaction, we can inquire into the effects of various media=
 on
collaboration. For a given task, for instance, should people use a text-bas=
ed,
asynchronous medium? How does this choice both facilitate and constrain the=
ir
interaction? If the software intervenes between collaborating people, how
should it represent them to each other so as to promote social bonding and
understanding of each other&#8217;s work?</p>

<p class=3DMsoNormal>The preposition in the phrase is ambiguous. Is <i
style=3D'mso-bidi-font-style:normal'>of</i> to be taken in a passive or
possessive sense? Does the mediation <i style=3D'mso-bidi-font-style:normal=
'>of</i>
group cognition refer to how the group cognition is mediated by the technol=
ogy?
Or, conversely, does it refer to how collaboration and shared meaning are
mediated by the group cognition&#8217;s act of mediating? This ambiguity is=
 not
accidental: in processes of mediation, that which is mediated, that which
mediates and the mediation itself tend to merge into a process of
co-determination in which each is defined and refined by the others.</p>

<p class=3DMsoNormal>By itself, the term <i style=3D'mso-bidi-font-style:no=
rmal'>group</i>
is quite straight-forward. In this context, we can take it to refer to a sm=
all
set of people, usually numbering about three to six. But combined with the =
term
<i style=3D'mso-bidi-font-style:normal'>cognition</i>, it strikes many peop=
le as
counter-intuitive. This is because cognition is often assumed to be associa=
ted
with psychological processes in individual minds. </p>

<p class=3DMsoNormal>The usual story about cognition, at least in the Weste=
rn
culture of the past three hundred years, goes something like this: an
individual experiences reality through his (<i style=3D'mso-bidi-font-style=
:normal'>sic</i>,
the paradigmatic rational thinker in this tradition is often assumed to be
male) senses. He thinks about this experience in his mind; c<i
style=3D'mso-bidi-font-style:normal'>ognition</i>, stemming from the Latin =
<i
style=3D'mso-bidi-font-style:normal'>cogito</i> for &#8220;I think,&#8221; =
refers
to mental activities that take place in the individual thinker&#8217;s head=
. He
may articulate a mental thought by putting it into language, stating it as a
linguistic proposition whose truth value is a function of the
proposition&#8217;s correspondence with a state of affairs in the world.
Language is a medium for transferring meanings from one mind to another by
representing reality. The recipient of a stated proposition understands its
meaning based on his own sense experience as well as his rather unproblemat=
ic
understanding of the meanings of language.</p>

<p class=3DMsoNormal>The story based on the mediation of group cognition is
rather different: in this view, language is an infinitely generative system=
 of
symbolic artifacts (words, phrases, genres, etc.) that embody the cultural
experiences of a community. It is a social product of the interaction of
groups&#8212;not primarily of individuals&#8212;discussing and acting in the
world in culturally mediated ways. Individuals who are socialized into the
community learn to speak and understand language as part of their learning =
in
order to participate in that community. In the process, they internalize the
use of language: e.g., as silent self-talk, internal dialog, rehearsed talk,
narratives of rational accountability, senses of morality, conflicted dream=
 lives,
habits, personal identities and their tacit background knowledge largely
preserved in language understanding. In this story, cognition takes place
primarily in group processes of inter-personal interaction, including
mother-child, best friends, husband-wife, teacher-student, boss-employee,
extended family, social network, gang, tribe, neighborhood, community of
practice, etc. The products of cognition&#8212;thoughts&#8212;exist in
discourse, symbolic representations, meaningful gestures, patterns of behav=
ior;
they persist in texts and other inscriptions, in physical artifacts, in
computer databases, in cultural standards and in the memories of individual
minds. Individual cognition emerges as a secondary effect, although it later
seems to acquire a dominant role in our introspective narratives.</p>

<p class=3DMsoNormal>Most people have trouble accepting the group-based sto=
ry at
first and then starting to view collaborative phenomena in these terms. Let=
 us
take a closer look at the philosophical view which is sedimented in the term
&#8220;mediation.&#8221; It belongs to a tradition that undertook a fundame=
ntal
critique of the individualistic perspective that goes back to Descartes and
even Plato, and that underlies common folk theories about cognition.</p>

<h1><a name=3D"_Toc79305484">2. Deconstructing Mediation</a></h1>

<p class=3DMsoNormal>We can start to deconstruct the term <i style=3D'mso-b=
idi-font-style:
normal'>mediation</i> as used in CSCL and CSCW by looking at its use in Lave
&amp; Wenger&#8217;s seminal <i style=3D'mso-bidi-font-style:normal'>Situat=
ed
Learning</i> [2]:</p>

<p class=3DQuote style=3D'margin-right:.5in'>&#8220;Briefly, a theory of so=
cial
practice emphasizes the relational interdependency of agent and world,
activity, meaning, cognition, learning and knowing&#8230;. Knowledge of the
socially constituted world is socially mediated and open ended.&#8221;</p>

<p class=3DMsoNormal>This theory of social practice can be traced back to H=
egel
and Marx by way of Vygotsky. Vygotsky described what is distinctive to human
cognition, psychological processes that are not simply biological abilities=
, as
<i style=3D'mso-bidi-font-style:normal'>mediated cognition</i>. He analyzed=
 how
both signs (words, gestures) and tools (instruments) act as artifacts that
mediate human thought and behavior&#8212;and he left the way open for other
forms of mediation: &#8220;A host of other mediated activities might be nam=
ed;
cognitive activity is not limited to the use of tools or signs&#8221; [5].
Vygotsky recommended replacing the exclusive focus on individual development
with a &#8220;zone of proximal development&#8221; that assessed group
cognition, the ability of small groups to achieve intellectual results [5].=
</p>

<p class=3DMsoNormal>Vygotsky attributes the concept of indirect or mediated
activity to Hegel and Marx. Where Hegel loved to analyze how two phenomena
constitute each other dialectically&#8212;such as the master and slave whose
identity arises through their relationship to each other&#8212;Marx always
showed how the relationships arose in concrete socio-economic history, such=
 as
the rise of conflict between the capitalist class and the working class with
the establishment of commodity exchange and wage labor. The minds, identiti=
es
and social relations of individuals are mediated and formed by the primary
factors of the contexts in which they are situated.</p>

<p class=3DMsoNormal>The term <i style=3D'mso-bidi-font-style:normal'>media=
tion</i>
takes on a variety of interrelated meanings and roles in discussions of soc=
ial
theory. The point here is to start to think of group collaboration software=
 as
artifacts that mediate the cognition of their individual users and support =
the
group cognition of their user community.</p>

<h1><a name=3D"_Toc79305485">3. Mediation by Groups</a> </h1>

<p class=3DMsoNormal>Small groups are the engines of knowledge building. The
knowing that small groups build up in manifold forms is what becomes
internalized by their members as individual learning and externalized in th=
eir
communities as certifiable knowledge. At least, that is a central premise of
this article. </p>

<p class=3DMsoNormal>Although we can see many examples of the decisive role=
 of
small groups, their pivotal function is rarely acknowledged. For instance, =
the
two prevailing paradigms of learning in CSCL&#8212;which may be referred to=
 as
the acquisition metaphor and the participation metaphor [3]&#8212;focus on =
the
individual and the community respectively, not on the intermediate small gr=
oup.
In the acquisition metaphor, learning consists in the acquisition of knowle=
dge
by an individual; for instance, a student acquires facts from a teacher&#82=
17;s
lesson. In the participation metaphor, learning consists in knowledgeable
participation in a community of practice; for instance, an apprentice becom=
es a
more skilled practitioner of a trade. But if one looks closely at the examp=
les
typically given to illustrate each paradigm, one sees that there is usually=
 a
small group at work in the specific learning situation. In a healthy classr=
oom
there are likely to be cliques of students learning together in subtle ways,
even if the lesson is not organized as collaborative learning with formal g=
roup
work. Their group practices may be structured in ways that support individu=
al
participants to learn as the group builds knowledge. The peer group may also
resist the official educational goals; the small group defines what is to be
valued as learning. In apprenticeship training, a master is likely to work =
with
a few apprentices, and they work together in various ways as a small group;=
 it
is not as though all the apprentice tailors or carpenters or architects in a
city are being trained together. The community of practice functions throug=
h an
effective division into small working groups.</p>

<p class=3DMsoNormal>Some theories, like activity theory [1], insist on vie=
wing
learning at both the individual and the community level. Although their
examples again typically feature small groups, the general theory highlights
the individual and the large community, but has no theoretical representati=
on
of the critical small groups in which individuals carry on their concrete
interactions and into which the community is hierarchically structured.</p>

<p class=3DMsoNormal>My own experience in research collaborations and in my
apprenticeships in philosophy and computer science impressed me with the
importance of working groups, reading circles and informal professional
discussion occasions for the genesis of new ideas and insights. The same ca=
n be
seen on a world-historical scale. Quantum jumps in human knowledge emerge f=
rom
centers of group interaction: the Bauhaus designers at <st1:City w:st=3D"on=
">Weimar</st1:City>,
the post-impressionist artists in <st1:City w:st=3D"on">Paris</st1:City> sa=
lons,
the <st1:Street w:st=3D"on"><st1:address w:st=3D"on">Vienna Circle</st1:add=

ame> <st1:PlaceType
 w:st=3D"on">School</st1:PlaceType></st1:place>&#8212;in the past these
communities were necessarily geographic locations where people could come
together in small groups at the same time and place.</p>

<p class=3DMsoNormal>The obvious question, once we recognize the catalytic =
role
of small groups in knowledge building, is: can we design computer-supported
environments to create effective groups across time and space? In order to
achieve this, we need a degree of understanding of small group cognition th=
at
does not currently exist. In order to design effective mediated collaborati=
on,
we need to develop a theory of mediated collaboration based on a design
research agenda of analysis of small group cognition.</p>

<p class=3DMsoNormal>Most theories of knowledge building in working and lea=
rning
have focused primarily on the two extreme scales: the <span style=3D'mso-bi=
di-font-weight:
bold'>individual</span> unit of analysis as the <span style=3D'mso-bidi-fon=
t-weight:
bold'>acquirer</span> of knowledge and the <span style=3D'mso-bidi-font-wei=
ght:
bold'>community</span> unit of analysis as the context within which <span
style=3D'mso-bidi-font-weight:bold'>participation</span> takes place. We no=
w need
to focus on the intermediate scale: the <span style=3D'mso-bidi-font-weight=
:bold'>small
group</span> unit of analysis as the <span style=3D'mso-bidi-font-weight:bo=

in which <span style=3D'mso-bidi-font-weight:bold'>knowledge</span> actually
emerges.</p>

     learning?</li>
</ul>

<p class=3DMsoNormal>The size of groups can vary enormously. Our examples t=
end to
be of small groups of a few people meeting for short periods. Given the
hypothesized importance of this scale, it is surprising how little research=
 on
computer-supported collaboration has focused methodologically on this unit.
Traditional approaches to learning measure effects on individuals. More rec=
ent
writings talk about communities of practice. Many studies of collaboration =
that
do talk of groups look only at dyads, where interactions are easier to desc=
ribe
and qualitatively different from those in larger small groups. </p>

<p class=3DMsoNormal>The emphasis on the group as a unit of analysis belong=
s at
the foundation of a science of collaboration. It is not just a matter of
claiming that it is time to focus software development on groupware and to
develop appropriate techniques (e.g., for assessment of groupware). It is a=
lso
a methodological rejection of individualism as a focus of empirical analysis
and cognitive theory. Software should support cooperative work and
collaborative learning; it should be assessed at the group level and it sho=
uld
be designed to foster group cognition. For that, we need a fitting theoreti=
cal
framework centered on an understanding of the role of small groups and the
mediation of group cognition.</p>

<h1>ABSTRACT</h1>

<p class=3DMsoNormal>In a recent Workshop on community-based learning at th=
e 6th
International Conference on Learning Sciences (ICLS 2004), one persistent t=
heme
was the variety of terms used to describe collections of people (group,
community, network, collective) and components of interaction (culture,
identity, collaboration, cooperation) in group learning activities. Here, we
describe some of the thinking that emerged in those discussions, not as a
comprehensive literature review or completely elaborated socio-cultural the=
ory,
but rather as an invitation to further discussion. We suggest that a <i>gro=
up</i>
is the most generic and general social category: all of the analytical unit=
s in
the literature on collective learning - teams, social networks, and communi=
ties
- are groups. We argue that these other terms have additional structural
characteristics that make them distinct subsets of the generic term <i>grou=
p</i>.
For example, a <i>team</i> is a group with a common task, a <i>network</i> =
is a
group with strong social ties, and a <i>community</i> is a group with a sha=
red
culture. We propose a two-dimensional space of social organizations
characterized by <i>shared culture </i>and <i>shared interaction</i>, and s=
uggest
both individuals and collectives show a developmental history through the s=
pace
of collectives, moving from loose group affiliation to increasing
identification with, development of, and participation in shared interactio=
ns
within a shared culture. This analysis suggests, we argue, that: (a) tools =
to
support &#8220;collaboration&#8221; may need different affordances for
different kinds of collectives; (b) understanding different kinds of
collectives requires different methodologies; and (c) culture plays a promi=
nent
role in the space of collectives we describe, and thus, we argue, should pl=
ay a
significant role in the analysis of any community. We hope that this brief
discussion will lead to further work on the social entities within which gr=
oup
learning takes place, on the processes of learning in such settings, and on=
 the
technologies that can support such processes. </p>

<h2>1.1. Collectives as Subjects in Learning Processes</h2>

<p class=3DMsoNormal>Much recent work on socio-cultural theories of learning
focuses on the processes of collaborative or (more precisely) collective
learning - that is, on how social collectives generate understanding through
group learning activities. In such studies, the collective (classes, learni=
ng
groups, lab groups, teams, learning communities, learning organizations,
virtual communities) is at the center of the analytical scheme rather than
individual learners in isolation. Similarly, much recent work in computer
science on human-computer interaction (HCI) has focused on tools that suppo=
rt
collaborative work and community-building [3&#8212;5; 8; 9]. In such work, =
the
focus is on the processes of collective action and on computational means to
support it in virtual settings.</p>

<p class=3DMsoNormal>The complex interplay between collective learning,
technological support and appropriate theoretical approaches for studying t=
hese
issues was the topic of a recent Workshop on Community-based Learning at the
6th International Conference on Learning Sciences (ICLS 2004). One persiste=
nt
theme in the workshop was the variety of terms used in these fields to desc=
ribe
the collections of people (group, community, network, collective) and
components of interaction (culture, identity, collaboration, cooperation) t=
hat
were being analyzed and supported.</p>

<p class=3DMsoNormal>In this short essay, we describe some of the collective
thinking that emerged in those discussions as we attempted to clarify the
relationships among different kinds of social groups and the interactive
processes that define them. We present these notes not as a comprehensive
literature review or completely elaborated socio-cultural theory, but rathe=
r as
a summary of current thinking and an invitation to further discussion of th=
ese
issues.</p>

<h1>2. SOCIAL CATEGORIZATION AND SOCIAL PERCEPTION</h1>

<p class=3DMsoNormal>In <i>Mind, Self, and Society</i>, George Herbert Mead=
 [7]
made a famous distinction between <i>me, myself, </i>and <i>I</i>, arguing =
that
the <i>self</i> that constructs the meaning of events and our understanding=
 of
our place in social systems is composed of a socially-constructed
&#8220;me&#8221; and the &#8220;I&#8221; responsible for constructing the w=
orld
by self-indicating happenings as salient objects. For Mead, the foundation =
of
the individual as a social organism is in this dual role of the self as sub=
ject
and object, indicator and indicated. </p>

<p class=3DMsoNormal>Categorization (in this broad sense of the term) is th=
us
basic to social experience - indeed, to the human experience. The reflexive
construction of self depends on the identification of &#8220;me&#8221; as a
certain kind of me, that is, as being similar to or different from others in
some way. &#8220;We&#8221; understand &#8220;ourselves&#8221; by dividing t=
he
world into &#8220;us&#8221; and &#8220;them,&#8221; into classes of individ=
uals
who are similar or different along a variety of biological, cultural, econo=
mic,
and social lines: families, tribes, peoples, races, strata, social classes,
genders, nations, cultures and subcultures.</p>

<p class=3DMsoNormal>The nature and formation of these socially-constructed
collectives is central to understanding learning as a social phenomenon, not
least because socio-cultural approaches to learning focus on enculturation =
and
identity-formation as central mechanisms for learning and development [1; 2=
; 6;
15; 15]. At the same time, however, in dealing with collective subjects fro=
m an
analytical perspective, researchers in learning science and human-computer
interaction tend to refer to collectives in deliberately neutral terms, suc=
h as
work groups, organizational units, departments, networks, school classes, or
learning communities. While such generic categories may be analytically use=
ful
in some circumstances, the result is that the literature on collective lear=
ning
sometimes appears less than systematic in delineating functional differences
among the central descriptors for the collectives being studied in
collaborative settings. Put another way: the nature and meaning of the
collective itself is central to the processes of socio-cultural learning, b=
ut
socio-cultural theories are loose in their use of descriptors for this cent=
ral
unit of analysis.</p>

<p class=3DMsoNormal>This dilemma was one of our central concerns, and much=
 of
our discussion focused on beginning to articulate a more robust framework f=
or
thinking about the nature and properties of the collectives within which (a=
nd
upon which) socio-cultural processes operate.</p>

<h1>3. FROM GROUP TO COMMUNITY: A FRAMEWORK</h1>

<h2>3.1. &#8220;Group&#8221; as Fundamental Social Category</h2>

<p class=3DMsoNormal>We suggest that the most generic and general social ca=
tegory
is a (social) <i>group</i>, being any collection of more than one person th=
at
shares a common attribute which distinguishes them from other persons. What=
 is
crucial is that a social distinction is made between members of the group a=
nd
non-members. That distinction may be embraced by the group or imposed
externally (as when race is legally codified, for example), but in either c=
ase
the formation of the group results in a process of <i>social identification=
</i>
or self-categorization as group members [10; 11]. This social identity is b=
ased
on the awareness that one belongs to a group, and represents the cognitive =
dimension
of social identity; it is also typically associated with an evaluative and =
an
emotional dimension of group identification. If a group member knows about =
his
own group membership and if this membership is accompanied by positive/nega=
tive
evaluation and emotions, this group membership becomes part of the social
identity of a person.</p>

<p class=3DMsoNormal>Whether a person is aware of his or her own group memb=
ership
is largely dependent on the social context and situation. According to <i>s=
ocial
identity theory </i>and <i>social categorization theory </i>[11&#8212;13], =
the
concept of <i>salience</i> describes the conditions influencing the relevan=
ce
of in-group/out-group categorizations for self-perception and behavior. To
illustrate this concept of salience, take a heterosexual couple trying to e=
nter
a public swimming pool on &#8220;Women Only Day.&#8221; In this situation, =
the
category of sex/gender (the self-categorization of &#8220;being
male/female&#8221;) becomes salient to the couple, while in other social
situations this differentiation might not be relevant. Thus, a social group
emerges from the interaction of individuals within a context in which the
distinctive attribute of the group makes a difference. </p>

<p class=3DMsoNormal>We thus suggest that <i>group </i>is the most fundamen=
tal
social category, in the sense that all of the analytical units in the
literature on collective learning&#8212;such as teams, social networks, and
communities&#8212;are groups. However, we argue that these other terms have
additional structural characteristics that make them distinct subsets of the
generic term <i>group</i>. In the next section of the paper we describe som=
e of
these distinguishing characteristics.</p>

<h2>3.2. Within Groups: Teams, Networks, Communities</h2>

<p class=3DMsoNormal><i>A team needs a common task. </i>We suggest that a <=
i>team</i>
or <i>working group</i> (or conceptual derivates such as <i>small group</i>=
 or <i>project
group</i>) are groups with a common task to fulfill. Team members have
self-perception and awareness of team membership that distinguishes the team
from the social outside. Teams also need to have some common understanding =
of
the work they share, a common (or at least overlapping) definition of goals=
 and
subgoals, and personal commitment to work for these goals. But these shared
understandings, goals, and identities are tied to the task at hand; the sha=
red
understanding of team activities, methods, and tools is locally instrumenta=
l to
the accomplishment of a particular task. When the task is fulfilled, the te=
am
disappears. In many cases, of course, teams are composed of members of some
larger <i>community </i>(see below), and thus shared symbols and patterns of
activity may persist as part of that larger community. Stahl (2004, in this
Issue) further suggests that as a practical matter, teams are limited in si=
ze
as well.</p>

<p class=3DMsoNormal><i>Social networks are defined by social ties. </i>A g=
roup
becomes a network when members are linked by social ties based on social
contact and communication - which in <i>network theory </i>are referred to =
as <i>knots</i>.
Within network theory, the frequency of communications within knots is take=
n as
the main indicator for the strength or weakness of social ties. Quality of =
the communication
is of less relevance, and <i>social network analysis </i>uses counts of
communicative acts between network knots to determine the structure of the
network. We might describe a team, then, as a temporary local network organ=
ized
around a particular task. </p>

<p class=3DMsoNormal><i>Communities need shared culture. </i>Unlike social
networks, communities cannot be characterized and analyzed only by the <i
style=3D'mso-bidi-font-style:normal'>quantity</i> of social contacts between
members. Communities, we suggest, are social networks (and therefore groups)
that are defined by the <i style=3D'mso-bidi-font-style:normal'>quality </i=
>of
their social ties. In particular, communities are networks with a shared <i=
>culture</i>:
a set of shared norms, conventions, and meanings; a set of common practices=
 and
common symbols that create a shared semantic space. </p>

<h2>3.3. Dimensions of Community</h2>

<p class=3DMsoNormal>In our discussions, we conceptualized these different
characterizations of collections of individuals as part of a two-dimensional
space of social organizations (see <span style=3D'mso-field-code:" REF _Ref=
82311770  \\* MERGEFORMAT "'>Figure
<span style=3D'mso-no-proof:yes'>1</span></span>). In particular, we
distinguished between <i>shared culture </i>and <i>shared interaction</i>, =
and
suggest that together these dimensions distinguish between collectives such=
 as
group, team, network, and community, as described above. We added an additi=
onal
category of <i>experts</i> to the diagram to account for collections of
individuals with a shared culture but little interaction. (Note that the set
boundaries in the figure are illustrative only.)</p>

 the
set boundaries are illustrative only. Trajectories of development.</p>

<p class=3DMsoNormal>Our space of collectives also suggests a clear develop=
mental
trajectory over time. Lave and Wenger&#8217;s [6; 2; 3; 14; 15] theory of <=
i>communities
of practice</i> suggests that learning is a process of enculturation into t=
he
shared practice of the community. This enculturation can be described by a
movement/development of newcomers from peripheral participation in the
community&#8217;s practice to more and more central roles in the community.=
 On
the individual&#8217;s side the process can be seen as a process of social
identification with the community&#8217;s goals, culture, and practice.</p>

<p class=3DMsoNormal>From the perspective of the collective, we note that t=
he
community itself develops through the progressive <i>development</i> of that
shared culture. The interactions over time of community members in a contin=
uous
process of negotiation and deliberation establish a common culture and buil=
d a
collective identity. The shared culture and shared interactions of communit=
ies
take time to develop and establish. The concept of <i>shared history of
learning</i> [14] thus applies both to the individuals in a community and to
the community as a whole. </p>

<p class=3DMsoNormal>Put another way, both individuals and collectives show=
 a
developmental history through the space of collectives, moving from loose g=
roup
affiliation to increasing identification with, development of, and
participation in shared interactions within a shared culture. </p>

<h1>4. DISCUSSION</h1>

<p class=3DMsoNormal>It comes as no surprise that the concepts of <i>cultur=
e</i>,
<i>identity</i>, and <i>history </i>are useful tools in understanding the
nature of collectives such as <i>groups</i>, <i>teams</i>, <i>networks</i>,=
 and
<i>communities</i>. We suggest, however, that there may be some utility in
beginning to map the relationships among such terms more explicitly. The
discussion here is only a small first step in that direction. However, even
this small step suggests that tools to support &#8220;collaboration&#8221; =
may
need different affordances for different kinds of collectives. The Web is a
particularly effective tool for supporting <i>networks </i>of people. Suppo=
rting
<i>communities</i>, however, will necessarily involve supporting a particul=
ar
culture, and thus (by definition) particular <i>kinds</i> of interactions.
Different communities will, therefore, almost certainly require different k=
inds
of tools&#8212;or tools that can be significantly customized for a particul=
ar
culture.</p>

<p class=3DMsoNormal>Understanding the structural and theoretical differenc=
es
between different kinds of collectives has methodological implications as w=
ell.
In particular, the analysis above suggests that social network analysis may=
 be
a useful tool to quantitatively analyze social structures; but it may be
insufficient to understand the work of communities, which are marked by sha=
red
culture, and thus where the quality of social interactions matters as much =
as
the quantity. </p>

<p class=3DMsoNormal>More broadly, this analysis suggests that while the <i=
>practices</i>
are an important component of groups, teams, and communities, what
distinguishes a community is its shared <i>culture</i>. This encompasses
practices, to be sure - and in the end, culture is constituted in and throu=
gh
practice. But culture plays a prominent role in the space of collectives we
describe above, and thus, we argue, should play a significant role in the
analysis of any community. Community-based learning is, in the end,
culture-based learning, and group learning (whether learning by individuals=
 in
the group or the group as a whole), is, as socio-cultural theorists suggest=
, a
process of enculturation.</p>

<p class=3DMsoNormal>In any event, we hope that this brief discussion of gr=
oups,
teams, communities and the similarities and differences among them will lea=
d to
further work on the social entities within which group learning takes place=
, on
the processes of learning in such settings, and on the technologies that can
support such processes. </p>

<h1>1. INTRODUCTION</h1>

<p class=3DMsoNormal>Professional development is increasingly conceived as a
sustained group or community process, often supported by online technologie=
s.
Yet despite the enthusiasm for online communities of practice [40], and the
innovative educational contexts being developed to support them, the realit=
y of
developing and maintaining a critical mass of teacher engagement is proving=
 to
be challenging (for example, the Inquiry Learning Forum (ILF) [4]; the Hawa=
ii
Networked Learning Communities (HNLC) [37]). Teacher educators and designer=
s of
technological learning environments continually strive to maximize the valu=
e of
teacher engagement in such contexts, yet the conditions under which social
learning and collaboration become an appropriate strategy for teachers rema=
in
unclear [4; 19]. Furthermore, contemporary research from evolutionary psych=
ology
[27] and modeling of cultural transmission [5] suggests the likelihood that
professional development in sustained groups would involve subtle yet
influential <i style=3D'mso-bidi-font-style:normal'>social</i> learning
strategies. For example, decisions regarding the adequacy of a particular
concept or professional behavior may be influenced by the status of the gro=
up
member advocating it, the frequency of the behavior in the group, or even w=
hich
idea or behavior was offered to the group first [1]. </p>

<p class=3DMsoNormal>(Online) teacher communities seem to offer a potent mo=
del
for professional development that aligns with contemporary understanding of
learning as situated, distributed and social [21]. However, there is a need=
 to
test theoretically driven justifications of communities of practice by
undertaking empirical investigations into how learning is actually occurrin=
g in
these social and technological contexts [3; 11; 34]. Obviously, the task of
developing strong explanatory frameworks that take us well past simple
descriptions is urgent. The fields of astronomy and molecular biology became
explanatory fields of science only after harnessing powerful theoretical le=
nses
borrowed from other fields [7]. When such explanatory frameworks were coupl=
ed
with advances in technology that expanded the ability to research these fie=
lds
empirically, the benefits were exponential. In education, design-based rese=
arch
[38] and subtle but powerful technological contexts for learning may provide
the strategic means to move forward. </p>

<h1>2. BEYOND THE INDIVIDUAL AS A UNIT OF ANALYSIS</h1>

<p class=3DMsoNormal>Underpinning many of the theoretical perspectives used=
 to
analyse social learning in pre-service and professional development context=
s is
the work of Vygotsky. Fundamental to this perspective is the notion that hi=
gher
mental processes have their origin within social processes. &#8220;Any func=
tion
in the child&#8217;s cultural development appears twice, or on two planes.
First it appears on the social plane, and then on the psychological plane.
First it appears between people as an inter-psychological category, and then
within the child as an intra-psychological category&#8221; (Vygotsky, cited=
 in
Wertsch [41]). Whilst Vygotsky&#8217;s theory has problematised the notion =
of
learning as an individual process, there is little consensus on how best to
tackle an analysis of learning beyond the individual. Many studies of online
communities, based explicitly on Vygotskian principles, still maintain a un=
it
of analysis at the level of the individual [2]. This approach may be neglec=
ting
the potential of analyzing learning <i style=3D'mso-bidi-font-style:normal'=
>as</i>
a group, as opposed to learning <i style=3D'mso-bidi-font-style:normal'>bec=
ause </i>of
a group. </p>

<p class=3DMsoNormal>Vygotksy&#8217;s notion of the &#8216;collective life&=
#8217;
as a source of individual learning gave theoretical impetus to
&#8216;thinking&#8217;, &#8216;voluntary attention&#8217; and &#8216;logical
memory&#8217; as group attributes [41]. Vygotsky&#8217;s theory of educatio=
nal
psychology has thus provoked strong interest in notions of distributed
cognition [18]; that is, cognition and learning that transcend the boundari=
es
of the individual.<a style=3D'mso-footnote-id:ftn2' href=3D"#_ftn2" name=3D=
"_ftnref2"
title=3D""><span class=3DMsoFootnoteReference><span style=3D'font-size:9.0p=
t;
mso-bidi-font-size:12.0pt'><span style=3D'mso-special-character:footnote'><=
![if !supportFootnotes]><span

mso-fareast-language:EN-US;mso-bidi-language:AR-SA'>[2]</span></span><![end=
if]></span></span></span></a>
Development on Vygotsky&#8217;s interpersonal plane has thus been conceived=
 as
a form of collective learning. Insights from his work have been incorporated
into (amongst others) two prominent sets of ideas within educational resear=
ch:
Wenger&#8217;s communities of practice [40] (deriving largely from prior, m=
ore
general notions of situated cognition [20]) and Engestrom&#8217;s activity
theory [10]. These approaches help us understand learning within the complex
dynamic of a community setting where there is a shared practice or activity
[15]; however, neglect of the &#8216;small group&#8217; as an important
mediator between the individual and the community is a concern for some [36=
],
given the key role Vygotsky afforded to small groups [41]. </p>

<p class=3DMsoNormal>Of particular significance to the present paper is
Vygotsky&#8217;s recognition of the need to move beyond a purely sociocultu=
ral
understanding of learning &#8211; specifically, by asserting the
interdependence of the biological and sociocultural realms in ontogenesis [=
41].
This may act as a reminder to educational researchers of the need to be ope=
n to
possible synergies with contemporary theories in other fields such as biolo=
gy,
neuroscience and evolutionary psychology. Perhaps he was assisting educatio=
nal
researchers towards a science of education through theoretical models that,=
 at
the very least, recognise the varied realms contributing to any act of
learning. Fletcher asserts such &#8220;external coherence&#8221; as an
indicator of a good scientific theory [12].</p>

<p class=3DMsoNormal>The biologically based generative theory of learning [=
31;
32] offers just such a perspective for educational research, deriving from
neuroscience [8; 9] and evolutionary psychology [26]. In this view, learnin=
g is
conceived as an adaptive behavior that hedges our chances of survival.
&#8220;To survive in its eco-niche, an organism must either inherit or crea=
te
criteria that enable it to partition the world into perceptual categories
according to its adaptive needs&#8221; [8]. According to generative theory =
this
process is undertaken through iterative cycles in which learners generate a=
nd
test ideas based on their value, selecting those ideas that survive these t=
ests
[9; 26; 31; 32]. The value-driven selection that underpins this process
operates through a generate-test-regenerate (g-t-r) heuristic that is
identifiable at three nested levels [26]:</p>

<ul style=3D'margin-top:0in' type=3Ddisc>
 <li class=3DMsoNormal style=3D'mso-list:l8 level1 lfo2;tab-stops:list .5in=
'>At a
     primary level in genes, by natural selection, as genetic knowledge-gai=
ning;</li>
 <li class=3DMsoNormal style=3D'mso-list:l8 level1 lfo2;tab-stops:list .5in=
'>At a
     secondary level in organ systems (immune systems and brains), as the
     selection of ideas and behavior tested against values that have been
     developed by individuals through their life-experience; and,</li>
 <li class=3DMsoNormal style=3D'mso-list:l8 level1 lfo2;tab-stops:list .5in=
'>At a
     tertiary level in groups and cultures, again, as the selection of ideas
     and behaviors, but tested against communal or cultural values.</li>
</ul>

<p class=3DMsoNormal>Within this generative framework, the heuristic&#8217;s
tertiary level proposes a particular understanding of social and collective
learning: the learning of each individual in a group is influenced not only=
 by
their unique pattern of values at the primary and secondary level, but
simultaneously by shared beliefs and values <i style=3D'mso-bidi-font-style=
:normal'>at
the collective level</i>; that is, within the group and culture in which th=
ey
are operating. As suggested already, this collective level can, itself, be
analyzed for learning and progression.</p>

<p class=3DMsoNormal>By suggesting a mechanism by which learning occurs at =
each
nested level, this theory bridges the divide between the individual and the
collective. As well, it opens up the possibility of ongoing empirical resea=
rch
that might well deliver external coherence with contemporary understanding =
in
the sciences.</p>

<p class=3DMsoNormal>The generative theory is already proving its worth for
understanding the learning of individual students and teachers [14; 30; 33]=
 and
in re-conceiving e-learning design [35]. Now, its worth in understanding
collective learning at the tertiary level is being explored [13]. The conte=
xt
for this research is an Australian project named DESCANT (SciTech)<a

In
its first phase, a small number of teachers (11 in all) were supported to
conceive and prototype their own e-learning environment for teacher
professional development in Science and Technology education. Such support =
was
largely undertaken through sustained online collaboration using both generic
and boutique software. Following the development of the environment, larger
groups of teachers will trial, modify and evaluate the e-learning environme=

for details). With its thorough collaborative research design, DESCANT has
provided a significant opportunity to investigate collective learning.</p>

<h1>3. TOWARDS A MODEL OF COLLECTIVE LEARNING</h1>

<p class=3DMsoNormal>Generative learning suggests a powerful explanatory
framework for collective learning. Now there is an urgent need for an
appropriate model that can leverage insight from empirical data concerning =
this
educational phenomenon. Due to the inherent complexity of a collective lear=
ning
context, this task is always going to be a methodological challenge. In the
DESCANT context, a model of generative learning that was originally develop=
ed
for analyzing <i style=3D'mso-bidi-font-style:normal'>individual</i> learni=
ng in
technology-and-science education [31] was used as a starting point. That mo=
del
identifies learning within six acts: exploring, designing, making, operatin=
g,
explaining and understanding.<a style=3D'mso-footnote-id:ftn4' href=3D"#_ft=
n4"
name=3D"_ftnref4" title=3D""><span class=3DMsoFootnoteReference><span
style=3D'font-size:9.0pt;mso-bidi-font-size:12.0pt'><span style=3D'mso-spec=
ial-character:
footnote'><![if !supportFootnotes]><span class=3DMsoFootnoteReference><span
style=3D'font-size:9.0pt;mso-bidi-font-size:12.0pt;mso-fareast-font-family:=
"Times New Roman";
mso-ansi-language:EN-US;mso-fareast-language:EN-US;mso-bidi-language:AR-SA'=
>[4]</span></span><![endif]></span></span></span></a>
Whilst it is beyond the scope of this paper to explain each of these acts, =
it
is important to note that the model is synergistic with the
generate-test-regenerate (g-t-r) heuristic. </p>

<p class=3DMsoNormal>The generative model was adapted for analyzing learnin=
g at
the collective level by conceiving of each of the six acts as a collective =
or
emergent phenomenon. This has proven extremely useful in providing insights
into the emergence of shared understandings and values in the DESCANT teach=
er
collective [13]. As further insights emerge regarding learning at this
collective level, there may be a need to expand the model to incorporate a =
more
explicit representation of such processes as enculturation [5] and the
influence of &#8216;collective intentionality&#8217; [25]. According to
Plotkin, &#8220;collective intentionality&#8221; (after the work of John
Searle), may be fundamental in understanding social force, and thus social
learning [25]. Collective intentionality: </p>

<p class=3DQuote style=3D'margin-right:.5in'>&#8220;&#8230;is not the sum of
individual intentionalities and is not reducible to them&#8230;This does not
mean that [it]&#8230;hovers in the spaces between people or binds their min=
ds
through mysterious field forces. Each of us has a mind and mental life that=
 are
confined to our individual brains. But to quote Searle, &#8216;it does not
follow from that that all my mental life must be expressed in the form of a
singular noun phrase referring to me. The form that my collective
intentionality can take is simply &#8220;we intend&#8221;, &#8220;we are do=
ing
so and so&#8221;, and the like. In such cases, <i style=3D'mso-bidi-font-st=
yle:
normal'>I intend only as part of our intending</i>. The intentionality that
exists in each individual head has the form &#8216;we intend&#8217;&#8221;
[25]. (Emphasis added)</p>

<p class=3DMsoNormal>Plotkin&#8217;s pragmatism in dealing with collectivity
emphasizes the possibility of addressing the link between the neural struct=
ures
of individuals and the regulation of these structures based on social
relationships. This collective regulation in ontogenesis has been described=
 as
&#8216;structural coupling&#8217; [22] and &#8216;co-emergence&#8217; [39],=
 and
has been used as the basis for understanding distributed cognition in an
educational context [6]. While such perspectives may be of great value in
developing a suitable model for empirically analyzing collective learning, =
the
methodological dilemmas remain. For example, what counts as evidence of
collective learning and how do we collect data about such emergent phenomen=
a?
Furthermore, how do we collect data on a process as subtle and implicit as
enculturation: a phenomenon that may be fundamental to understanding how
cultural values and shared understandings progress within a population? Yet
perhaps in this regard we are in a more fortunate position than Vygotsky was
decades ago.</p>

<h1>4. A TECHNOLOGY FOR UNDERSTANDING COLLECTIVITY</h1>

<p class=3DMsoNormal>Within the physical sciences, the advent of new techno=
logies
has always played a significant role in the advancement of understanding by
allowing humans to engage empirically with what was previously unreachable =
[7].
Papert&#8217;s vision of technologically rich environments as supplying
&#8216;objects-to-think-with&#8217; made a similar vision explicit for
education [24]. In educational research, the explicit nature of communicati=
on
over the Internet has proven valuable for studying many facets of social
learning and community design. Nevertheless, within such online contexts,
emergent phenomena such as collective learning remain implicit: something f=
or
researchers to carve out of the complex context based on their models or
theoretical approaches. However, technologies that seek to capture this
collective level are now under development. For example, in classrooms,
Knowledge Forum software encourages explicit representation of learning wit=
hin
knowledge building communities [15; 29]. Within a professional development
context, Lessonlab technology is affording teachers a cumulative knowledge =
base
that incorporates a dynamic mechanism for verification and improvement [16]=
.</p>

<p class=3DMsoNormal>In DESCANT, teachers have identified both the need for=
 an
e-learning environment that makes explicit the progression of learning at a
collective level and some ways this might be operationalized. This environm=
ent
is currently under development and will be trialed, as the final phase of t=
he
DESCANT project, with a new cohort of teachers early in 2005. For professio=
nal
development, such an environment may well supply an &#8216;object to think
with&#8217; [24] by making learning at the collective (or even cultural) le=
vel
more tangible. Furthermore, with this collective realm of learning made
increasingly visible and explicit, researchers may be afforded new
opportunities to probe more deeply into what now seem to be mysteries of so=
cial
learning, just as their counterparts in the physical sciences have done so
successfully when afforded appropriate technologies. </p>

<h1>1. INTRODUCTION</h1>

<p class=3DMsoNormal>The classroom is bustling with activity and Miss Lawson
calls out, &#8220;five more minutes.&#8221; Scattered throughout the room a=
re
groups of four and five students crowded around each of the five low-standi=
ng
circular work desks. A palpable buzz of enthusiasm fills the air as these
groups deliberate amongst themselves before hurriedly filling in the large
sheets of poster paper sitting on their work desks. </p>

<p class=3DMsoNormal>Felicity, <st1:place w:st=3D"on">Tara</st1:place>, Hal=
ia,
Scott and Brad, referred to as group &#8220;3-3&#8221; by their classmates,=
 are
located in the middle of room. <st1:place w:st=3D"on">Tara</st1:place> sits
propped on one leg, stretching across the table, eyes trained on the
2&#8217;x3&#8217; piece of paper with the heading, &#8220;How does the leng=
th
of straw affect the performance of the car?&#8221; Felicity and Scott, hudd=
led
at the other end of the round table, are working at a frenetic pace to meet=
 the
deadline. They switch back and forth between the colored markers, weaving in
and out in a seemingly choreographed rhythm while avoiding bumping into each
other as they both draw and write on the poster. Meanwhile, Brad and Halia
stand over their shoulders, at the ready to attend to any calls for help or
information. Felicity calls out, &#8220;What were the times for the 18cm
straw?&#8221; Halia, leafs through the notes and replies, &#8220;for trial =
one
it was 3.6 meters, trial two, 4.9, trial three, 4.2.&#8221; Then, turning it
over to the soft-spoken Brad, who in a coordinated effort was simultaneously
entering the numbers on his calculator, &#8220;The average is 4.2m and the
velocity is .31 meters per second.&#8221;</p>

<p class=3DMsoNormal>There is a constant flow of dialog between the five. R=
aising
her head up from drawing the &#8220;motion story board,&#8221; Felicity, in=
 a
reflective tone, tries to get the group&#8217;s attention,
&#8220;shouldn&#8217;t the net force arrow go the other way?&#8221; Her fir=
st
attempt goes unattended, and she tries again, this time shifting to a kneel=
ing
pose, &#8220;dudes, I think the arrows go the other way!&#8221; Scott stops
what he is doing, turns, and for a few seconds the two recreate the motion =
of
the car through their gestures. &#8220;If the car&#8217;s moving in this
direction&#8221; gesturing to the left, &#8220;then the net force is also in
that direction&#8221; gesturing to the left. <st1:place w:st=3D"on">Tara</s=
t1:place>
chimes in &#8220;I agree with Felicity, when the car is coasting, the net f=
orce
is in the opposite direction&#8221; motioning to the right, while Halia nod=
s in
support. The conversation continues for a few more turns and then Felicity
concludes by repeating their agreement, &#8220;good! When the car&#8217;s
coasting there is only friction force, [and] the arrow goes this way&#8221;
once again gesturing the direction as she speaks.</p>

<p class=3DMsoNormal>Working on what appears to be a slightly different tra=
ck,
Brad, from time to time, turns and scans the wall closest to him. This wall,
like all the other available walls of the classroom, is covered with
presentation posters from this and other classes taught by Miss Lawson. Wit=
hout
an exchange of words, Brad moves to the other side of the room and checks o=
ut
more posters. This apparent unilateral action receives the full endorsement=
 of
the group who all turn when he states &#8220;Yeah, group 4-2 also tested st=
raw

<h1>2. BACKGROUND</h1>

<p class=3DMsoNormal>Over ten years ago, scholars such as Brown and Campione
proposed a re-conceptualization of the traditional classroom in order to en=
hance
the possibilities of learning in real world settings [5]. The central aspec=
t of
the learning environment was to support learning by providing a rich domain=
 of
knowledge, structure activities to use this new knowledge within that domai=
n,
guide learning by instruction and modeling of thinking and reflection, and
deliberately setting aside considerable time for students to engage in
explaining processes to themself and others [6]. Their approach to engineer=
ing
the classroom was referred to as Foster Communities of Learners (FCL). A mo=
re
generic use of this metaphor may be identified as <i style=3D'mso-bidi-font=
-style:
normal'>learning communities</i>, which describes other collaborative, inqu=
iry
and project-based learning environments, united by social theory (e.g.,
Vygotsky&#8217;s <i style=3D'mso-bidi-font-style:normal'>zone of proximal
development</i>; Wenger&#8217;s <i style=3D'mso-bidi-font-style:normal'>com=
munities
of practice</i>) [19; 20]. Examples of these types of classroom and curricu=
lum
projects are found at the institutional research level (e.g., <i
style=3D'mso-bidi-font-style:normal'>Knowledge-Building Communities</i> at =
OSIE
[18]), curricula level (e.g., Learning by Design&#8482; physical science and
earth science units [14]) and project level (e.g., science curriculum proje=
ct
[7]). </p>

<p class=3DMsoNormal>The success of these instances, as illustrated by the
scenario above, demonstrates the importance and potential of
multi-voiced/minded construction of knowledge (i.e., shared/social aspect of
negotiation of meaning) while engaged in authentic activities. Some have be=
gun
to look at the various components of these engineered classrooms and what m=
akes
them successful [7; 16]. One thing is clear: we still do not fully understa=
nd
how to tease apart the complexity of these learning environments to study t=
he
interactions of the social and cognitive components while still being sensi=
tive
to their emergent qualities. In short, how do complex dynamic systems made =
up of
multiple agents and socio-cognitive/cultural affordances co-develop and cha=
nge
(i.e., learn) over time? And, from a theoretical perspective, how do we beg=
in
to construct models of this cognitive development, which accounts for
individual (student) and collective (workgroup, and whole class) reasoning =
and
learning, without taking a reductive approach?</p>

<p class=3DMsoNormal>In order to explore ways of understanding these settin=
gs and
addressing the concerns listed above, I propose adapting a dynamic systems
approach, which combines complex adaptive systems theory (CAS) with two oth=
er
characteristics (timescales and history) of complex systems [3; 10]. The
intention of this paper, therefore, is to merely introduce this idea and
demonstrate how it may be used to understand the scenario described above (a
Learning by Design&#8482; [LBD] classroom). I begin with a brief rationale =
and
overview to situate the reader, and conclude with an outline of the proposed
dynamic systems analytical model and its possible strengths.</p>

<h1>3. UNDERSTANDING LEARNING IN CLASSROOMS</h1>

<p class=3DMsoNormal>Increasingly, learning is viewed as the outcome of soc=
ially
negotiated activity, situated in potentially rich environments, within comp=
lex
communities of sometimes unequal participants [9; 15; 17]. Furthermore, from
the distributed cognition school of thought, we are asked to extend the
definition of cognition from individual learner to include the small group,=
 or
class as learner. Hutchins proposes: &#8220;a social group is a cognitive
system that may have cognitive properties very different from those of the =
individuals
who constitute the group&#8221; [13]. Although his research describes the
cognitive practices of &#8220;well-oiled&#8221; teams, it is arguable that =
it
also applies to the communities of learners we observe in constructivist
classrooms. </p>

<p class=3DMsoNormal>One possible approach to understanding these dense and
layered learning environments is to employ the analytical framework of Acti=
vity
Theory, a cultural-historical theory of activity presented by Lev Vygotsky =
and
his colleagues [8]. It suggests that cultural means, tools and signs mediate
interactions between the human agent(s) and objects in the environment. Bar=
ab,
Evans &amp; Eun-Ok Baek provide an excellent example of its use as a lens
through which they come to understand the design and participation activity=
 of
an online community [2]. Although Activity Theory is a powerful tool for
explaining the interactions of socio-cognitive/cultural systems, I propose =
it
is nonetheless worthwhile to explore the explanatory potential of other mod=
els
such as the adapted dynamic systems model.</p>

<p class=3DMsoNormal>Advocating the use of systems models to explain social
organization and learning is not a novel idea. Boyd argues for the use of
elements of cybernetic theory &#8211; &#8220;cybersystemics&#8221; &#8211; =
to
describe classrooms and other social systems [4; personal communications]. =
Barab,
Cherkes-Julkowski, Swenson, et al., propose an <i style=3D'mso-bidi-font-st=
yle:
normal'>autocatakinetic</i> systems approach, which suggests that learning
would be understood best as a &#8220;participatory process involving
contextualized practice and meaning as part of an ecological system&#8221; =
[1].
More directly, Hurford proposes using <st1:place w:st=3D"on"><st1:City w:st=
=3D"on">Holland</st1:City></st1:place>&#8217;s
Complex Adaptive Systems theory (CAS) as a model of individual student lear=
ning
[10; 11]. He provides an excellent account of how <st1:place w:st=3D"on"><s=
t1:City
 w:st=3D"on">Holland</st1:City></st1:place>&#8217;s CAS &#8220;mechanisms&#=
8221;
can be applied to explain human learning. My use of this theory differs from
Hurford&#8217;s in two ways. Firstly, I am interested in describing the
interactions between the three levels of learning &#8211; individual,
workgroup, and class; secondly, I am particularly interested in exploring t=
he
role of what <st1:place w:st=3D"on"><st1:City w:st=3D"on">Holland</st1:City=
></st1:place>
refers to as a &#8220;property&#8221; of CAS, namely &#8220;Flows&#8221; [1=
0].</p>

<h1>4. ADAPTING <st1:place w:st=3D"on"><st1:City w:st=3D"on">HOLLAND</st1:C=
ity></st1:place>&#8217;S
MODEL OF COMPLEX ADAPTIVE SYSTEMS</h1>

<p class=3DMsoNormal>A complex system is a hierarchically organized collect=
ion of
a large number of coupled components defined by stated boundaries. The smal=
lest
unit of the system is referred to as an individual &#8220;agent&#8221;
operating under specified rules resulting in a higher level of organization,
which exhibits <i style=3D'mso-bidi-font-style:normal'>emergent</i> propert=
ies.
Put simply, emergence is a phenomenon wherein the interaction of a
system&#8217;s parts (agents) results in a higher order of organization
(meta-agent or system) causing the system to behave differently from what o=
ne
could predict from knowledge of the parts alone, and which takes on a diffe=
rent
set of operational instructions. According to Holland, complex adaptive sys=
tems
(CAS) exhibit certain &#8220;properties&#8221; (Aggregation, Nonlinearity,
Flows, and Diversity) and &#8220;mechanisms&#8221; (Tagging, Internal Models
and Building Blocks), which contribute to the process of emergence characte=
rized
by the unique, amplifying (sometimes dampening), nonlinear behaviors of the=
se
systems [10]. </p>

<p class=3DMsoNormal>Expanding on this description, a system&#8217;s emerge=
nt
properties can be viewed as patterns or recurring structures resulting from
nonlinear interactions of lower level parts (agents), that are governed by
specific rules and relationships. These rules and relationships are the
mechanisms that afford emergence, which is the resultant state of coupling =
all
the lesser processes of aggregation/self-organization, nonlinearity/stochas=
tic
behaviors, tagging/selection, and flows of resources. Furthermore,
tagging/selection mechanisms regulated through flows of resources allow for
adaptation of the system. These powerful combinations are all affected by t=
he
&#8220;history&#8221; of the system, and unfold over varying
&#8220;timescales.&#8221;</p>

<p class=3DMsoNormal>For this paper, I will examine only how the component =
<a
name=3D"OLE_LINK2"></a><a name=3D"OLE_LINK1"><span style=3D'mso-bookmark:OL=
E_LINK2'>&#8220;Flows&#8221;
</span></a>can be useful in helping us understand learning communities.
&#8220;Flows&#8221; describes the process that allows the system&#8217;s
resources to be distributed. It may in fact be the glue that holds the syst=
em
together. By carefully observing flows within a system we can identify all =
the
relevant nodes (individuals, groups, artifacts, or environmental components)
and their connectors (designate possible interactions). Additionally, if we
study a system for an extended period, flows also allows us to identify the
changing connectors (their appearance, disappearance), which in turn helps =
to
explain why agents adapt or fail to adapt, as well as the
development/adaptation of the system as a whole. &#8220;Thus neither the fl=
ows
nor the networks are fixed in time. They are patterns that reflect changing
adaptations as time elapses and experience accumulates.&#8221; [10]</p>

<h1>5. ILLUSTRATION</h1>

<p class=3DMsoNormal>To illustrate my point, I will use the CAS characteris=
tic of
Flows to interpret the classroom scenario described above. It is by no means
intended to represent a fully elaborated analysis using the CAS model, but
instead provide a flavor of what can be understood about individual and gro=
up
cognition using this single component.</p>

<p class=3DMsoNormal>To start, we identify the system as the classroom, wit=
h the
workgroups and individuals as meta-agents and agents, respectively. We then
identify &#8220;information and knowledge&#8221; as the major resource with=
in
the system. The obvious &#8220;agent/nodes&#8221; are Miss Lawson and the f=
ive
students. And, the easily identified &#8220;connectors&#8221; are the verbal
communications (Ms. Lawson&#8217;s announcement - &#8220;five more
minutes&#8221;; Felicity&#8217;s request for information -&#8220;what were =
the
times...?&#8221;; Halia&#8217;s reply - &#8220;for trial one it was...&#822=
1;).
For the moment, if we look exclusively at this level of interaction we can
identify connectors between the teacher and the group, Felicity and Scot, a=
nd
the onlookers Tara, Halia, and Brad (see Figure 1).</p>

 Initial
observed interactions from the scenario described.</p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>Studying the scenario more closely we recognize that t=
he
presentation poster (2&#8217;x3&#8217; paper and written contents) and
classroom walls (poster archives) as other nodes within the system. In fact,
these nodes are very significant because they contain the history of the sy=
stem
and the workgroups. In addition to these nodes, we also recognize a larger
number of connectors within the system, such as the kinesthetic actions of =
the
students (Felicity and Scot gesturing the direction of the force diagrams; =
Brad
running to the poster wall), which also allow the flow of information within
the system.</p>

<p class=3DMsoNormal>From this perspective, the limited initial set of
interactions becomes a large network of possible interactions (see Figure 2=
).
This lens allows us to view Felicity as a significant agent/node, whose
question (&#8220;shouldn&#8217;t the arrow...?&#8221;) plays a central role=
 in
connecting other agent/nodes and artifact/nodes. Her initial question, which
results from the flow of information within the connector between her and t=
he
poster, is amplified by subsequent flows of information within the connecto=
rs
between her and the agent/node Scot; as well as flows of other coordinated
activity (verbal utterances and gestures) within the connectors. It also ca=
lls
the attention of the other members of the group, demonstrated by Tara who
chimes in, &#8220;I agree with Felicity&#8221;, and Halia, who nods in
agreement.</p>

<p class=3DMsoNormal><!--[if gte vml 1]><v:shape id=3D"_x0000_i1027" type=

<p class=3DMsoNormal><b style=3D'mso-bidi-font-weight:normal'>Figure 2</b>:=
 Closer
observation of interactions from the scenario described.</p>

<p class=3DMsoNormal><o:p>&nbsp;</o:p></p>

<p class=3DMsoNormal>What does this tell us? On the level of the individual=
 it is
reasonable to suggest that Felicity and Scot, who are directly interacting =
with
a major node/artifact (presentation poster), are most likely actively
constructing knowledge. On the level of the workgroup, this CAS lens helps =
to
explain the role of the presentation poster as a contributor to the
group&#8217;s cognitive development. It does this by allowing us to view the
other agent/nodes, who at first appear to be merely onlookers to this
multi-modal exchange, as collaborators through their agreement (verbal and =
nonverbal).
Although Tara, Halia and Brad do not appear to be directly engaged, the
connectors between them and the temporary &#8220;cluster&#8221; node (Felic=
ity
and Scot) become more evident as the scenario progresses. And, although
Brad&#8217;s interaction (connector) with the wall/node (seeking missing
information) does not relate to the discussion of the cluster node (Felicity
and Scot&#8217;s conversation), it does demonstrate that he is attending to=
 the
poster/node. Hence, possibly explaining why his individual cognitive develo=
pment
may be different from members of his workgroup. </p>

<h1>6. CONCLUSION</h1>

<p class=3DMsoNormal>This sample application using the lens of CAS Flows al=
lows
us to see some of the value of this model. It can account for the individua=
l as
well as the group because it focuses on the interactions rather than on any=
 of
the two organizational levels. It also accounts for the history component of
complex systems (although this point is not developed). I argue that it all=
ows
us to explain the &#8220;shared enterprise&#8221; in such a way as to descr=
ibe
collective learning in a non-reductive manner.</p>

<p class=3DMsoNormal>This is important because we need a dynamic and inclus=
ive
model, which allows us to account for the multiple agents (student, teacher,
workgroup, artifact, environment) and the product of their interactions, wh=
ich
may be collective artifacts, or collective knowledge. Complex dynamic syste=
ms
theory provides us with such a tool, and allows us to construct models of t=
hese
systems so that we may better understand them and predict the impact of cha=
nges
within them, such as their adaptations, how certain features are selected, =
and
the importance of history and timescales in the development and evolution of
the learning communities.</p>

<h1>1. INTRODUCTION</h1>

<p class=3DMsoNormal>Over the past decade and a half, work in the field of
education on<i> communities of practice </i>[20] and/or <i>communities of
learners </i>[2] has focused on how individual development takes place with=
in
the larger context of the norms and activities of a community. Recognizing
this, educators working within the sociocultural tradition have focused on
documenting the practices of extant communities [12; 18--20; 35] and/or on =
ways
in which the &#8220;community of practice&#8221; of the classroom can be
improved [2; 25]. Broadly speaking, this work looks at how the traditional =
intellectual
disciplines (such as math, science, and history) are mobilized in the conte=
xt
of real-world practices, or how importing more authentic practices into sch=
ool
settings can develop disciplinary understanding more effectively.</p>

<p class=3DMsoNormal>One problem with such approaches is that the tradition=
al
disciplines focus on knowledge rather than action. The ivory tower is
deliberately isolated from the day-to-day problems of life in the world [7].
Mathematicians, historians, and research scientists clearly form communitie=
s of
practice. It is less clear, however, that their authentic practices are the
most useful models for the majority of students&#8212;or that the disciplin=
es
they practice are the most important ends in a post-industrial society.</p>

<p class=3DMsoNormal>In this short paper, I describe <i>pedagogical praxis<=
/i>
[33] as a fundamentally different approach to thinking about communities of
practice in educational settings. Pedagogical praxis focuses on the develop=
ment
of useful and socially valued ways of thinking through personally and socia=
lly
meaningful activity. That is, pedagogical praxis links learning and doing
within the framework of communities of practice, but it does so by reframing
two fundamental premises of much recent work. First, pedagogical praxis
suggests that professional practices such as medicine, law, architecture, a=
nd
journalism have distinct and coherent <i>epistemic frames </i>[32] analogou=
s to
the &#8220;ways of thinking&#8221; usually attributed to the traditional
disciplines. These epistemic frames, rather than the traditional discipline=
s,
are taken as the educational goal. Second, pedagogical praxis suggests that=
 by
engaging in epistemically faithful adaptations of the reproductive practice=
s of
professional communities, students can gain access to these ways of
knowing&#8212;and thus, to ways of thinking that are fundamentally grounded=
 in
the meaningful activities of a post-industrial society.</p>

<h1>2. PEDAGOGICAL PRAXIS</h1>

<p class=3DMsoNormal>New technologies make it possible for young people to
participate more directly in the world of adult activities, whether using s=
oftware
tools to develop new mathematical proofs [21], participating in the collect=
ion
and analysis of real scientific data [6], or publishing work on the Interne=
t.
Thus, new technologies make it easier for students to learn about the world=
 by
participating in meaningful activity. This idea is not new; rather, it expl=
ains
one way that new technologies support Dewey's vision of bringing the
&#8220;life of the child&#8221; into an environment for learning [3].</p>

<p class=3DMsoNormal>Dewey argued that knowing and doing are tightly couple=
d, and
thus learning needs to take place in the context of activity [3; 22]. Moreo=
ver,
as Dewey suggested in <i style=3D'mso-bidi-font-style:normal'>Art as Experi=
ence</i>,
learning involves meeting and overcoming obstacles in the process of trying=
 to
accomplish a meaningful goal. &#8220;Resistance and check,&#8221; he wrote,
&#8220;bring about the conversion of direct forward action into re-flection=
 [<i>sic</i>]&#8221;
[4]. Schon argues that professionals enact this link between knowing and do=
ing
through a process of reflection-in-action: literally, &#8220;a capacity to
combine reflection and action, on the spot... to examine understandings and
appreciations while the train is running&#8221; [26]. Schon's work suggests
that professionals learn to think in action, and that they learn to do so <i
style=3D'mso-bidi-font-style:normal'>through </i>their professional experie=
nces.
Reflective practice involves taking action and then reflecting on the resul=
ts
with peers and mentors.</p>

<p class=3DMsoNormal>As Vygotsky and other theorists have suggested, this
reflective process is progressively internalized: the norms, habits,
expectations, abilities, and understandings of a community of
practice&#8212;the ways of thinking and acting of the community&#8212;become
part of the identity of the individual [8; 19; 20; 36--39]. Lave and Wegner
describe a community of practice as a group of individuals who share a
repertoire of knowledge about and ways of addressing similar (often shared)
problems and purposes. In the process of participating in the learning
practices of such communities, individuals develop ways of thinking and ref=
rame
their identities and interests in relation to the community [20]. For examp=
le,
journalists share common ways of thinking and working, and individuals who =
work
in the field of journalism incorporate these ways of thinking and working i=
nto
their sense of self, coming to think of themselves, at least in part, as
journalists. </p>

<p class=3DMsoNormal>Different communities of practice (for example, differ=
ent
professions) have different epistemologies: different ways of knowing, of
deciding what is worth knowing, and of adding to the collective body of
knowledge and understanding. I have described these different epistemologie=
s in
more detail elsewhere as epistemic frames: the grammar of a culture of prac=
tice
that binds practice, identity, interest, and understanding with a coherent
epistemology [32]. In the context of professional activities, these ways of
knowing are constituted in practice, and the processes of professional trai=
ning
are designed to link praxis and epistemology through pedagogical activity.
Pedagogical praxis thus takes a <i>learning practices perspective </i>[12; =
28],
using the ways in which professionals are trained as a model for learning
environments. This is in contrast to approaches that develop learning
environments based on the activity structures of experts in professional
practice in real world contexts [3; 11; 13; 17; 19; 20].</p>

<h1>3. DESIGN OF LEARNING ENVIRONMENTS</h1>

<p class=3DMsoNormal>The challenges in educational design from the perspect=
ive of
professional learning practices are three-fold. First, one must uncover the
structure of learning practices as they are currently constituted: the
relationships among activity, pedagogy, and epistemology that different
learning practices embody. Second, one has to map the relationships between=
 the
epistemologies of practice and the kinds of understanding (cognitive, socia=
l,
moral, and practical) that we want young people to develop in the course of
their education. And third, we have to develop techniques for adapting exta=
nt
learning practices to create environments that are true both to the ways of
knowing of those practices and to the central skills, habits, and understan=
dings
that young people need to incorporate given their developmental trajectory.
That is, we need to know how professional learning practices work, how they
relate to what young people need to learn, and how to use technology to bri=
ng
those practices within young people&#8217;s grasp.</p>

<p class=3DMsoNormal>Environments that develop constructive skills, habits,=
 and
associations function as coherent systems [2; 23; 31]. Any successful
implementation of a context for learning depends on a clear articulation not
only of &#8220;surface procedures,&#8221; but also of the underlying
&#8220;principles of learning&#8221; [2]. One approach to creating such
coherence, explored by many designers of thoughtfully innovative learning
environments, is to articulate a set of principles that will guide the desi=
gn
of activities and assessments [1; 2; 5; 9; 10; 13--17; 24; 25]. A challenge=
 in
this approach is that the number of principles and practical constraints
multiplies quickly. Designing an environment that is practical and
simultaneously addresses a complex system of requirements can be daunting. =
</p>

<p class=3DMsoNormal>Pedagogical praxis takes a different approach. Because
professional learning practices have evolved into coherent systems over tim=
e,
pedagogical praxis suggests that professions such as accounting, architectu=
re,
mediation, engineering, journalism, law, and medicine can provide particula=
rly
powerful models for developing technology-based learning environments in wh=
ich
young people can learn important skills, habits, and associations [29; 31].=
 The
model of pedagogical praxis is to uncover the principles embedded in existi=
ng
learning practices (a problem of cognitive anthropology and interpretive
ethnography), develop technologies to help students participate in these
practices (a problem of engineering and technology development), and then
create experimental learning environments designed to develop life skills
through participation in a community of practice (a problem of program desi=
gn
and action research).</p>

<p class=3DMsoNormal>That is, rather than looking to professional practices=
 to
find principles that can be used to design classroom activities to teach ma=
th,
science, or history, pedagogical praxis seeks to create environments that a=
re <i>thickly
authentic</i>. Resnick and I [34] have argued that authenticity is an align=
ment
between activities and some combination of (a) goals that matter to the
community outside of the classroom, (b) goals that are personally meaningfu=
l to
the student, (c) ways of thinking within an established domain, and (d) the
means of assessment. Thickly authentic learning environments create all of
these alignments simultaneously&#8212;for example, in the case of pedagogic=
al
praxis, when personally meaningful projects are produced and assessed accor=
ding
to the epistemological and procedural norms of an external community of pra=
ctice.</p>

<p class=3DMsoNormal>In this vision, new technology reinvigorates Dewey's i=
dea of
learning important life skills through active engagement in meaningful acti=
vity
[3]. Young people learn by working as &#8220;practicing&#8221; professionals
[26; 27; 29--31]. Pedagogical praxis focuses on communities (or cultures) of
practice not as a means to an end, but as an end in themselves: to help you=
ng
people incorporate into their identity development a variety of ways of
thinking that are used to shape the world in which they live.</p>

<p class=3DMsoNormal>The implications of pedagogical praxis are thus quite
profound. They suggest that the ways in which professionals acquire their
practices may provide an alternative model for organizing our educational
system. Thickly authentic adaptations of professional learning practices ma=
ke
it possible for students to learn through participation in valued reflective
practices, and thus give educators an opportunity to move beyond disciplines
derived from medieval scholarship constituted within schools developed in t=
he
industrial revolution&#8212;a new model of learning for an era of dramatic
social and economic transformation brought about by new technology. </p>

<h1>1. INTRODUCTION</h1>

<p class=3DMsoNormal>While peer collaboration is the basis for co-learning =
in
many groups, in the classroom the prevailing assumption is that teachers
facilitate student learning, through course structure, setting learning tas=
ks
and outcomes, presentation, discussion, facilitating small group learning,
coaching, and mentoring, among others. Though instructional design models h=
ave recognized
that learning builds on interactions between learners and their environments
(teachers have moved from &#8220;sage on the stage&#8221; to &#8220;guide on
the side&#8221;), these models tend to focus on individual student learning
rather than group learning. </p>

<p class=3DMsoNormal>Educational contexts are, by nature, group learning
environments. Through the mediation of language, students <i style=3D'mso-b=
idi-font-style:
normal'>and</i> teachers acquire new understandings when individuals transf=
orm
their structures of meaning in response to knowledge frameworks and the mea=
ning
structures of other individuals. Pedagogy truer to a social constructivist =
view
of learning would shift the locus of learning toward the group to account f=
or
these processes of transformation, which according to Vygotsky are based on=
 an
internalization of social experiences that is built on higher mental functi=
ons,
cultural development, and self-regulation [14]. Gerry Stahl in &#8220;Media=
tion
and Group Cognition&#8221; proposes that these processes can best be seen
operating in small groups as group cognition, with individual cognition
emerging as a secondary effect [12]. In this view, group cognition is both =
the
process and product of interpersonal interaction mediated by language. </p>

<p class=3DMsoNormal>I propose that reflection &#8212; done individually and
collaboratively &#8212; is a core activity of group cognition. Using higher
mental functions (e.g., metacognition) and self-regulation, individuals
perceive, respond to, and integrate new knowledge gained as a result of the=
ir
relations with others [1]. When learners co-reflect, their understandings a=
re
deepened, broadened, and intensified. In online learning environments, the
products of cognition &#8212; thoughts &#8212; as they exist in discourse a=
re
embodied in the records captured by the computer. In this paper, I investig=
ate
the nature of reflection and co-reflection through data derived from an onl=
ine
action research course I recently facilitated.</p>

<h1>2. ONLINE ACTION RESEARCH COURSE</h1>

<p class=3DMsoNormal>In the spring of 2004, I facilitated an online course =
for
learning about action research with two graduate students working toward a
school library media specialist certification in the <st1:place w:st=3D"on"=
><st1:PlaceType
 w:st=3D"on">University</st1:PlaceType> of <st1:PlaceName w:st=3D"on">Hawai=
</st1:PlaceName></st1:place>&#8216;i
Library and Information Sciences Program. Both Ruth and Sarah (pseudonyms) =
not
only studied action research but also applied it to their tele-mentoring of=
 two
high school students, undertaken simultaneously with the course. Using data
derived from email messages, chat transcripts, server logs, participant-cre=
ated
web pages, journals, interviews, and observations during our few face-to-fa=
ce
meetings, I examined how the co-construction of knowledge occurs and how it
contributes to an understanding of action research. </p>

<p class=3DMsoNormal>The course used the simplest online software available
(wiki-style collaborative software), implemented by a learning facilitator =
who
believes in the importance of &#8220;social capital.&#8221; I based the cou=
rse
design on these ideas:</p>

<ul style=3D'margin-top:0in' type=3Ddisc>
 <li class=3DMsoNormal style=3D'mso-list:l4 level1 lfo6;tab-stops:list .5in=
'>Learning
     is a whole-person activity involving cognitive, affective, and social
     dimensions [1; 4; 14; 15]. </li>
 <li class=3DMsoNormal style=3D'mso-list:l4 level1 lfo6;tab-stops:list .5in=
'>Knowledge
     is socially constructed [5; 14]. </li>
 <li class=3DMsoNormal style=3D'mso-list:l4 level1 lfo6;tab-stops:list .5in=
'>Relationship
     building based on respect, trust, and sincerity is as fundamental to
     online learning environments as it is to face-to-face environments [9;
     16].</li>
 <li class=3DMsoNormal style=3D'mso-list:l4 level1 lfo6;tab-stops:list .5in=
'>&#8220;Social
     capital&#8221; is basic to learning success and should drive the
     development of the computer software [2; 10].</li>
 <li class=3DMsoNormal style=3D'mso-list:l4 level1 lfo6;tab-stops:list .5in=
'>Empowerment
     is an important goal of learning [7; 8].</li>
</ul>

<p class=3DMsoNormal>In discussing their own philosophies as teachers, the
students revealed that they generally shared these ideas. Though we had tau=
ght
at different levels (elementary, high school, and adult education), we aime=
d at
empowering our students through constructivist teaching, accommodating
different learning styles, and building relationships with and among our
students. We also shared the service orientation of librarianship. Our
relationship building during the course was facilitated by a shared profess=
ional
culture as teachers and librarians.</p>

<p class=3DMsoNormal>I chose the text-based wiki software because I believed
that: (1) students who create their own web pages as an integral part of the
learning process are more likely to reflect and to sustain their motivation=
 for
learning in the virtual environment; (2) the products of the learning proce=
ss
should remain as a source of individual and community memory for shared
learning and further reflection; (3) it is important for instructors to have
the flexibility to adapt the website to evolving learner needs; and (4) the
flexibility of the software can encourage participants to adapt their learn=
ing
and communication strategies and patterns to the online environment.</p>

<p class=3DMsoNormal>The students and I interacted primarily via email and =
weekly
chats. The students also used the software for module assignments, journal
entries, brainstorming, writing drafts, bibliographies, and progress charts=
. I
used the software to structure the course; to post assignments, student work
samples and course readings; to link to external resources; and to create c=
hat
summaries, among others.</p>

<h1>3. ONLINE &#8220;VISIBILITY&#8221;</h1>

<p class=3DMsoNormal>Visibility of thoughts, feelings, and actions is the b=
asic
element upon which mutual understanding, social bonding, and group cognition
are built. Despite our shared professional culture, significant differences
affected our visibility to each other and our learning interactions. These
included learning style preference, attitude toward technology, and the
existence of a prior relationship. </p>

<p class=3DMsoNormal>Ruth, an elementary school teacher, stated that she wa=
s a
visual learner who often uses graphic representations and conceptual mappin=
g to
take notes and to work out her ideas. With the exception of simple tables, =
the
wiki software does not support graphic representations. Not surprisingly, t=
his
text-based medium inhibited her ability to express herself. She also noted =
that
she was cautious in her online communication, as she felt it was prone to
misinterpretation without the nonverbal cues and immediate feedback availab=
le
in face-to-face interaction. Her email messages were generally brief and
business-like. She had previously taken an online course that made her
uncomfortable with online communication, particularly chat. At the end of t=
he
course, she ranked our few face-to-face interactions as more important than
email or chat for her learning progress (though less important than journal=
ing,
as I discuss in the next section). Because she and I had not developed a
relationship prior to the course, this signified to me the importance of
including face-to-face interactions in an online course, where possible. </=
p>

<p class=3DMsoNormal>Sarah was a high school English teacher adept and at e=
ase
with writing. She had not previously taken an online course, although she h=
ad
experienced hybrid courses in which online communication was used to support
face-to-face interaction. The text-based medium, both synchronous and
asynchronous, supported her ability to express herself. She openly expressed
her thoughts and feelings, even uncertainties and anxieties, often thinking
&#8220;out loud&#8221; as she wrote. Her frequently long emails were writte=
n in
a conversational style. She and I had established a relationship in an earl=
ier
class. At the end of the course, she stated that, although she had gotten to
know me far better during the course, she felt that she was able to express
herself more freely because a relationship of trust had already been
established. </p>

<h1>4. REFLECTION AND CO-REFLECTION AS GROUP COGNITION</h1>

<p class=3DMsoNormal>What emerged as the critical indicator of individual a=
nd
group cognition was the use of reflection skills. Action research requires
reflective inquiry toward the goal of improved practice. The key aspects of
reflection identified in the students&#8217; discourse were: (1) being awar=
e;
(2) returning to experience; (3) attending to feelings; (4) probing experie=
nce;
(5) evaluating experience; (6) making a leap of thinking; and (7) integrati=
ng
new understanding. These features are supported by the work on reflective
inquiry and reflective practice done by Dewey, Schon, and Boud et al. [3; 6;
11].</p>

<p class=3DMsoNormal>I propose that the reflective self can take two stance=
s in
the processes of group cognition, depending on level of interaction. Regard=
less
of level, the reflective self operates according to Vygotsky&#8217;s assump=
tion
that &#8220;human learning presupposes a specific social nature and a proce=
ss
by which [individuals] grow into the intellectual life around them&#8221; [=
13].
Immersion in intellectual life involves interaction with the thoughts,
feelings, and experiences of others who may or may not be co-present in the
learning group. </p>

<p class=3DMsoNormal>In the first stance, the reflective self engages in in=
quiry
without seeking feedback. Interaction in this case is subtle. It begins wit=
h a
response to others who are brought to mind through reading, memories of
previous interactions, or vicarious experience. The products of this reflec=
tive
process can make a valuable contribution to group cognition in online learn=
ing
environments when records of thoughts, feelings, and actions remain visible=
 to
co-learners as potential sources of further reflection. </p>

<p class=3DMsoNormal>The second stance &#8212; co-reflection &#8212; is more
overtly interactional. I define co-reflection as a collaboratively undertak=
en
reflective process. Based on the concept of dialogic inquiry developed by
Gordon Wells, I use the term to indicate an inquiry process at a higher lev=
el
of intellectual and emotional maturity than the K-12 educational context us=
ed
by Wells [15]. The nature of co-reflection is that participants build knowl=
edge
together through discourse, bringing in their experiences and the use of
relevant information to achieve understanding of a topic, issue, or problem=
 of
interest. They engage in collaborative learning &#8212; meaning-making with
others &#8212; in order to extend and transform their understanding through=
 a
jointly undertaken activity. Co-reflection is fostered in relationships bas=
ed
on respect, trust, concern, and sincerity.</p>

<p class=3DMsoNormal>Ruth exemplified the first stance and in fact used the
course to develop her reflection skills. In her journals, she described a
greater awareness of her perceptions, values, and teaching practices that w=
as
powerful and empowering. The emergence of a more deeply reflective self see=
med
to have been triggered by the course content and early focus. In an early
journal entry, she notes that the course readings &#8220;heightened my
awareness of the littlest things, and seemingly meaningless events have
magically transformed themselves into deep connections &#8230; Taking a clo=
ser
look at one&#8217;s own practice allows one to not only examine how one
teaches, but more importantly why particular actions were taken, what actio=
ns
could have been taken, and places the focus on actions that can be controll=
ed,
your very own &#8230; It also entails coming to a deeper grasp of the
questions: Who am I? What do I stand for? What do I believe in? Why did I m=
ake
the choices that I did?&#8221; In her research project for the course, she
investigated her own learning style through her online interactions with me=
 and
with the high school student she was mentoring. In the process, her view of
herself as a teacher was transformed. In her final paper, she stated, &#822=
0;I
am empowered by the desire to discover more and learn more about how I go a=
bout
interpreting the world around me.&#8221; At the end of the course, the
component she ranked as most important for her learning progress was
journaling. The power of her insights extended beyond herself to the learni=
ng
group. Both Sarah and I read Ruth&#8217;s online writings and acknowledged
their value for expanding our thinking.</p>

<p class=3DMsoNormal style=3D'mso-pagination:none;mso-layout-grid-align:non=
e;
text-autospace:none'>In contrast, Sarah came to the course with well-develo=
ped
reflection skills. She co-reflected with me as her primary partner. For her
research project, she examined the online questioning strategies she used w=
ith
her tele-mentee for &#8220;building a relationship in a virtual setting.&#8=
221;
We actively exchanged email messages throughout her process of focusing her
topic, clarifying action research concepts, coding email messages with her
tele-mentee, analyzing data, and writing her final paper. As she was writing
her paper, she engaged in a significant co-reflection activity. To gain a
deeper understanding of action research, she re-read, reflected on, and
responded to all 11 of the chat summaries I had created to date, giving me
further food for reflection. Importantly, she indicated how online
communication supports the internalization of group-mediated learning:
&#8220;When I went into the chat that night I was a little lost. During the
chat, my confusion cleared and I started to feel I had a handle on my ideas.
Later, when Joyce listed out my claims, evidence and possible warrants [in =
the
chat summary], I almost did a double take &#8212; she had made everything s=
eem
so clear and at the same time, I don&#8217;t think my notes from the chat w=
ere
this clearly set out. I&#8217;m so thankful that the wiki enables us to ret=
urn
again and again because if she had just said these things to me, they would=
 now
be lost.&#8221;</p>

<p class=3DMsoNormal>As well as being a learning facilitator, coach, and me=
ntor,
I was also a co-learner about the art of teaching. Sarah and I had an exten=
sive
discussion about the nature of constructivist teaching/learning that result=
ed
in a multifaceted view combining our different approaches. Sarah initiated:
&#8220;My main question with constructivist teaching is how do you give the
student the freedom yet provide the framework so the learning is rigorous? =
Is
the rigor in the final product that the teacher assigns? This doesn&#8217;t
seem true to constructivism &#8212; it seems the student must determine the
assignments?&#8221; She noted that she was &#8220;too new at independent and
action research&#8221; to feel confidence in herself as a constructivist
learner. </p>

<p class=3DMsoNormal>This struck a chord with me: &#8220;All semester I&#82=
17;ve
also been thinking about &#8216;freedom and chaos.&#8217; I reorganized the
wiki during spring break because it was getting chaotic. The reorganization=
 was
based on what I learned WITH you and Ruth throughout the semester. You&#821=
7;ve
sparked an idea for me &#8212; I think constructivist learning is successful
only with the proper balance of structure and freedom. The structure can co=
me
from the course; it can also come from the students &#8212; inside their he=
ads
based on prior experience and thinking.&#8221; </p>

<p class=3DMsoNormal>Sarah responded, &#8220;Although you might have seen t=
he
course as chaos, I never really did because&#8230; I trusted you to guide me
through whatever needed to be done. I was too busy trying to understand the
readings and think of my research question to consider if things needed to =
be
more structured. I think I was in my own little world.&#8221; She also
acknowledged the value of her previous experiences for understanding action
research, &#8220;There have been many times during the course that I felt l=
ost,
but I framed the information in regard to my teaching and considered how it=
 was
true or how it applied for me in the classroom.&#8221; She added that findi=
ng
the balance of freedom and structure must be challenging in large classes, =
&#8220;I&#8217;m
sure you can see that Ruth and I are at different places in our learning and
that we react differently to the readings. Imagine if you had a class of 25=
-30.
How does the teacher create this balance then, in a constructivist
setting?&#8221;</p>

<p class=3DMsoNormal>I realized the need for more course structure while st=
ill
valuing individual initiative to drive inquiry learning: &#8220;I now
definitely see the advantages of having more structure in the course from t=
he
beginning, with the freedom to deviate from that structure along the way if
necessary. You mentioned &#8216;being in your own little world.&#8217;
That&#8217;s precisely where you should be. I have a quote taped to my
bookshelf that inspires me about teaching, from Martha Graham: &#8216;It is
that openness and awareness and innocence of sorts that I try to cultivate
among my dancers &#8230; it is not a question of putting something in but
drawing it out, if it is there to begin with ... I would like to feel that I
had, in some way, given them the gift of themselves.&#8217;&#8221;</p>

<p class=3DMsoNormal>Sarah responded, &#8220;I like this quote from Martha =
Graham
&#8212; especially the part about education is &#8216;drawing it out as if =
it
is in there all the time.&#8217; I think I wouldn&#8217;t have agreed with =
this
quote even about five years ago because I think that education is about
exposing students to new ways of thinking or approaching the world, but now=
 I
see that it is true in the sense that in order for the learning to be
meaningful for the students, it needs to make sense to them and be personal=
ly
relevant.&#8221; </p>

<p class=3DMsoNormal>This discussion helped me clarify my understanding of
constructivist learning &#8212; that the freedom to co-construct knowledge
relies heavily on how an individual learner&#8217;s structure of meaning
interacts with disciplinary frameworks and with the meaning structures of
others. Because of this, teaching is a process of invention. </p>

<h1>5. CONCLUSION</h1>

<p class=3DMsoNormal>While it may be more difficult to identify indications=
 of
group cognition in dyads than in larger groups, similar processes seem to b=
e at
work. This paper proposes that reflection is a core activity for meaning ma=
king
and knowledge building at the small group level, whether dyadic or larger.
Reflection skills enable learners to perceive, respond to, and integrate new
perspectives, and co-reflection achieves a broader and deeper understanding
than is possible through individual reflection alone. The students in this
study used their reflection skills differently to understand and apply the
ideas and tools of action research, but the products of their differentiated
learning contributed to group cognition.</p>

<p class=3DMsoNormal>These products are embodied in communication that is
permanently captured and always accessible online. As Stahl states, &#8220;=
The
knowing that small groups build up in manifold forms is what becomes
internalized by their members as individual learning and externalized in th=
eir
communities as certifiable knowledge&#8221; [12]. The online medium enhances
the ability to externalize knowledge and thereby strengthens the potential =
for
internalization by individuals.</p>

<p class=3DMsoNormal>What factors may influence group cognition in learning
environments? The first is whether the intent to learn as a group exists,
related to the instructional model used. Other factors include learning sty=
le
preference, attitude toward technology, and the degree to which trusting
relationships are built. </p>

<p class=3DMsoNormal>Regarding technology support for group cognition, this=
 study
suggests that &#8220;visibility&#8221; and &#8220;humanization&#8221; are v=
ital
in the online medium. Lacking nonverbal cues to indicate understanding,
confusion, joy, delight, frustration, or anxiety, online communication needs
explicitness about thoughts, feelings, and actions to offset the potential =
for
misinterpretation of messages. The computer software and social capital
(respect, trust, concern, and sincerity) should support a high degree of
expressiveness, both verbal and visual. This raises other questions. What t=
ools
and representations should be built into the software? How can the software
allow individuals the freedom and flexibility to create and co-create while
providing structure, rhythm, and visibility in an efficient manner? What is=
 the
optimum balance? And finally, how can we assess the quality not only of
individual cognition but also of group cognition? How do we identify not on=
ly
individual empowerment but also group empowerment?</p>

<h1>1. INTRODUCTION</h1>

<p class=3DMsoNormal>Grounded in constructivist instructional philosophy [5=
] and
a view that the purpose of schooling is to prepare students for a changing
workplace [7; Partnership for 21<sup>st</sup> Century Skills, www.21stcentu=
ryskills.org],
learning scientists turned to communities of practice (CoPs) to get inspira=
tion
for the design of learning activities in classrooms that resemble the
'authentic' and 'real-world' situations found in CoPs outside of schools. F=
or
domains that are naturally close to the workforce, like domains in the
sciences, technology, engineering, math, and others, it seems a perfect mat=
ch
and classroom environments are transformed to resemble CoPs [4; 6; 9].</p>

<p class=3DMsoNormal>How would a similar attempt work with domains traditio=
nally
not as close to the workforce and situated in the humanities, and how would
domain-differences play a role in the design of CoPs within formal in-school
education? The purpose of this position paper is to provide a preliminary
examination of the complexity of transferring the ideas of CoPs into the
re-design of humanities classrooms. The context of this position paper is an
on-going process on re-designing classes that lie in the core of humanities,
particularly classes in the Philosophy of Science (PoS) and several classes=
 in
Religious Studies.</p>

<p class=3DMsoNormal>While studying the PoS, one engages in questions such =
as:
&#8220;What is the nature of science, scientific explanation, and scientific
knowledge?&#8221;; &#8220;What are the underlying theories of truth in
science?&#8221;; &#8220;What are conceptual consequences modern science imp=
oses
generally on basic philosophies of knowledge and nature?&#8221;; and
&#8220;What makes an investigation scientific?&#8221; In short, PoS asks
questions on the assumptions of scientific belief and practice.</p>

<p class=3DMsoNormal>Religious Studies is a humanistic discipline that uses=
 a
variety of methodologies from other disciplines like sociology and
anthropology. A widely accepted definition of religion states that it is
&quot;a system of symbols which acts to establish powerful, pervasive, and
long-lasting moods and motivations in [people] by formulating conceptions o=
f a
general order of existence and clothing these conceptions with such an aura=
 of
factuality that the moods and motivations seem uniquely realistic&quot; [3],
but as an hermeneutic discipline it is better to be cautious, for as Smith
(1998) says &quot;One re-defines religion every time one studies it&quot; [=
10].</p>

<h1>2. Types of Communities</h1>

<h2>2.1. Communities of Practice</h2>

<p class=3DMsoNormal>For a number of scholars, the design of instruction is=
 the
same as the design of practice fields, which means that &quot;designing a
learning environment begins with identifying what is to be learned and
reciprocally, the real world situations in which the activity occurs&quot; =
[1].
Learning outcomes are derived from these situations with authenticity as th=
eir
most valued attribute; they need to have similar &quot;cognitive demands the
learner would encounter in the real world&quot; [1]. In practice fields,
students are engaged in domain-related practices around domain-related prob=
lems
like how to design a bridge, rather than around school problems like
well-structured story problems involving right/wrong solutions to
formula-driven problems. </p>

<p class=3DMsoNormal>In their critique on the shortcomings of practice fiel=
ds and
their call for CoPs in education, Barab &amp; Duffy argue that schools have
inherent problems to becoming practice fields because the activities are st=
ill
connected with grades - which makes them unauthentic - and they are solely
practice-oriented and not oriented towards real contributions to a community
outside of their school [1]. </p>

<h2>2.2. Communities of Reflection<span class=3DCharChar1><span style=3D'fo=
nt-family:
"Times New Roman"'><o:p></o:p></span></span></h2>

<p class=3DMsoNormal>Both approaches - practice fields and communities of
practice - have a strong underlying assumption that these CoPs are communit=
ies <i>practicing
</i><span style=3D'mso-bidi-font-style:italic'>or<i> doing</i></span> commo=
nly
performed tasks. It is safe to say that there is a wide acceptance of the f=
act
that communities of practice in chemistry, for example, are full of people
actually <i>doing </i>chemistry and being engaged in a CoP. The situation l=
ooks
different for the particular approach to practice advocated by a field like=
 the
Philosophy of Science. There are not a lot of communities <i>practicing</i>
these approaches outside of academia. Because most practitioners are profes=
sional
philosophers employed by schools and universities, there are no well-defined
CoPs for the Philosophy of Science.</p>

<p class=3DMsoNormal>There are, however, a lot of practitioners actively en=
gaged
in scientific CoPs practicing science. They operate under assumptions within
their scientific field, and therefore, in Barab's and Duffy's sense, can be
seen as a CoP for the field of Philosophy of Science [1], i.e., a CoP of
practicing chemists engages in reflection-in-action as part of their practi=
ce
as &quot;reflective practitioners&quot; [8]. However, people engaged in the=
 CoP
of chemistry are not necessarily as equally involved in the practice of
reflection as they are in the actual practice of chemistry. Reflecting on t=
heir
assumptions and engaging in a meta-discourse of their own practice does not
form the center of their day-to-day work; these may be under-articulated, a=
nd
tacit elements. I propose a distinction between the overall CoP and the
sub-community of reflection (CoR). This distinction might help us to better
focus on different elements, functions, and goals of qualitatively different
communities within a larger CoP. A field like PoS can help to make reflecti=
ve
components and tacit elements of a CoP more explicit. Under-utilized fields=
 or
fields which are perceived to have less value for a larger CoP, like PoS,
become more important and necessary for broader issues when designing CoPs =
in
classrooms. </p>

<h2>2.3. Communities of Reflection-Practice</h2>

<p class=3DMsoNormal>So far, this paper has distinguished between a communi=
ty of
practice and a sub-community of reflection. In the CoP of chemistry there i=
s a
practice of chemistry and a practice of reflection on doing chemistry. These
intertwined communities have well-defined boundaries that are set by
professions, widely accepted forms and modes of contribution to a larger
community, and they inform each other in their practice.</p>

<p class=3DMsoNormal>Let's examine if the proposed distinction is useful, o=
r if
we need further refinement, by beginning to focus on the domain of Religious
Studies. When we try to build a CoP in classrooms, who are the practitioner=
s we
focus on in the field of Religious Studies? We cannot start with religious
professionals like church workers or medicine women. This focus would be too
narrow and would include only areas of theology, ministry, or religious
education, which are not the same as Religious Studies. The aim of Religious
Studies is much broader, and is described earlier in this paper. </p>

<p class=3DMsoNormal>If we are not focusing on 'religious' professionals, t=
here
are no other professions outside of academia and we have to turn to a much
larger spectrum to find an example of practice. Human beings and/or differe=
nt
cultural systems at large come to mind. Religion is a worldwide phenomenon =
and
depending where individual researchers draw their definitory lines, religio=
n seems
to be everywhere. This multitude of 'cultural' CoPs are different from the =
CoPs
described in earlier sections of this paper: the practice is not defined by
professions and by well-set boundaries. Other aspects are similar: there are
commonly shared practices, well-accepted forms and modes of contribution to=
 a
larger community, and there is a practice of reflection within the different
CoPs. </p>

<p class=3DMsoNormal>Does the introduction of cultural CoPs help us to buil=
d CoPs
in Religious Studies classrooms? Engineering professors and students can en=
gage
in the building of bridges and can reflect on their practice and the practi=
ce
of engineers outside of classrooms who are building bridges, and it would b=
e an
'authentic' activity. Religious Studies scholars would find it difficult and
artificial to build religious communities or cults and establish rituals and
other religious activities in their classroom. Religious Studies scholars a=
nd
their students are not producing sacred texts and their time for research a=
nd
teaching is not referred to as sacred time. Religious Studies scholars, rat=
her,
are engaged in comparative studies, ontological development, reflections on=
 the
nature of religion, and reflections on the impact of religions in other are=
as
of culture such as politics. </p>

<p class=3DMsoNormal>Religious Studies is consistent with CoPs that deal wi=
th a
variety of different CoPs and is not necessarily the reflective sub-communi=
ty
of one particular CoP. The practice of Religious Studies scholars is solely
reflective and does not necessarily influence the practice of the CoPs it is
reflecting on. I propose a distinction between a community of reflection wh=
ich
is a sub-set of the community of practice, and a community of
Reflection-Practice (CoRP).</p>

<h1>3. CLASH OF COMMUNITIES</h1>

<p class=3DMsoNormal>The search for instructional strategies and design mod=
els
for communities of practice in school environments revealed several appeali=
ng
methods, including inquiry-based, discovery-based, real world case-based, a=
nd
problem-based scenarios, an involvement of out-of-school experts and contri=
butions
to communities surrounding the school or remote ones through Information and
Communication Technology (ICT). </p>

<p class=3DMsoNormal>For subject areas that draw their examples from defined
jobs, tasks, and problems like engineering or biology, the design of
'real-world' challenges is hard but rather well-structured by definition.
Medical and business students are engaged in case studies, often with real
patients or clients; engineering students build bridges in parks and
environment-friendly houses; bio-technology students unveil genome structur=
es
to design genetically altered food together with a bio-tech company; journa=
lism
students are regular contributors to news media; and instructional design
students (re-)design training and support systems with human development de=
partments.</p>

<p class=3DMsoNormal>Designing learning environments that are oriented towa=
rds
'real-world' challenges for PoS, Religious Studies, or other similar
disciplines is harder and ill-structured, especially if it is not even clear
what these might be or how they could be staked out. </p>

<p class=3DMsoNormal>Often, the connection with real world problems added
complexity and richness into classrooms, which were both seemingly missing =
from
textbook learning or simplified school examples. For the students though, i=
t is
more that the problems add an engagement with responsibilities, procedures =
and
constraints that they are likely to discover in the jobs they seek outside =
the
classroom. The change that came with a stronger emphasis on the implementat=
ion
of recent developments in learning sciences was welcomed, not only due to t=
he
fact that the field of learning sciences responded to a need, but also beca=
use
the development of newer learning theories was deeply rooted in the fields =
of
Science, Technology, Engineering, and Mathematics (STEM) and other workforc=
e-oriented
fields.</p>

<p class=3DMsoNormal>How do these developments look when applied to the
humanities and related fields? We experience a clash of cultures when we br=
ing
models and approaches of the learning sciences together with subject areas =
for
which they were not developed, i.e., in which models are implemented rather
than developed. The implementation can result in emerging struggles to
negotiate data structures and ontologies [4], in inappropriate use of metho=
ds,
and in conflicts between scientific inquiry methods and hermeneutic ones in
historical contexts (see example in [2]).</p>

<p class=3DMsoNormal>When the learning sciences meet a subject area like Po=
S,
with its community of scholars (instructors and practitioners) in the field,
questions arise and need to be addressed, such as: &#8220;How does the lear=
ning
sciences community interact with the other community?&#8221;; &#8220;Are th=
ey
building a new community?&#8221;; &#8220;Are they supporting each other or =
interfering
with each other?&#8221;; and &#8220;Are they supporting or objecting to ima=
ges
of the community instead of the community itself?&#8221;</p>

<p class=3DMsoNormal>I am far from putting value behind the different ways =
change
can appear from the interaction between different communities. Change can be
(not) wanted, (not) desired, or even (un)desirable. However, the interaction
and the change still need careful attention.</p>

<h1>4. CONCLUSION<span class=3DCharChar1><span style=3D'font-family:"Times =
New Roman"'><o:p></o:p></span></span></h1>

<p class=3DMsoNormal>Using some classes in humanities as lenses to look at =
CoPs,
these preliminary thoughts question an uncritical use of the term CoP to
describe and prescribe communities without differentiating between different
types and functions of communities. The implications of the distinction bet=
ween
communities of practice, communities of reflection, and communities of
reflection-practice and their intertwined relationships as well as the
potential and experienced clashes of communities are numerous: concepts,
models, and theories developed in the learning sciences might not work as w=
ell
in some communities as in others. Still, it is in the interest of both, the
numerous learning sciences communities and the communities of humanities
scholars, to engage in projects that have the goal to enrich students' lear=
ning
experiences beyond the school walls. </p>

creation processes, also known as learning processes, can be researched by
socio-cultural constructivist theories of learning like those advanced by
Vygotsky, Piaget, and Bateson [1; 8; 11]. Because knowledge creation in sci=
ence
is often a collaborative and communicative endeavour that is based on shared
experience and practice involving the apprenticeship of student researchers=
, we
deploy approaches where knowledge emerges in communities of practice (CoP) =
by
discursive assignment of sense [6; 12]. For historical and actual communiti=
es
of practice in science we make the basic assumption that there are two
disciplinary structures for the archives of the discourses [10]: goal and
forward-oriented (&#8216;linear&#8217;) structures on the one hand, and
discursive and displaying (&#8216;non-linear&#8217;) structures on the othe=
r.
In the linear case, the &#8216;old knowledge&#8217; is left behind, vanishe=
s in
the archive, and is replaced by newly published knowledge. In the non-linear
case, &#8216;old knowledge&#8217; can be introduced into the ongoing discou=
rse
at any time. This type of knowledge is kept in disciplinary dynamic archives
and contextualized in the historical process. In the mediation process,
&#8216;old&#8217; knowledge is not subsumed in the creation of
&#8216;new&#8217; knowledge, but is transcribed and displayed [3; 4]. The
process of displaying this knowledge is inherently linked with the knowledge
creation process and, therefore, is a media problem on its own. The
hermeneutical process is nerved by self-reflective loops of insight and
mediation. The appropriate IS metaphor for these processes is the model of
multimedia hypertext or hypermedia.<o:p></o:p></span></p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>S=
upporting
communication and knowledge creation in digitally networked cultural science
communities represents a specific challenge for the development and
organizational-structure of hypermedia information systems due to at least
three reasons. <span style=3D'mso-bidi-font-weight:bold'>First, </span>the
discursive nature of knowledge creation in the humanities is based on an
intense exposure to hypermedia </span>artifacts<span lang=3DEN-GB
style=3D'mso-ansi-language:EN-GB'> and underlying theories that require the
support of different digital media to be combined with (almost) arbitrary
metadata, constituting the situational background of an artifact. These dig=
ital
</span>artifacts<span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'> have =
special
semantics for each user and each community of practice. Dynamic context
management concepts for digital hypermedia artifacts supporting a high degr=
ee
of <i style=3D'mso-bidi-font-style:normal'><span style=3D'mso-bidi-font-wei=
ght:
bold'>semantic freedom</span></i> are thus needed for discourses in the
humanities. <span style=3D'mso-bidi-font-weight:bold'>Second, <i
style=3D'mso-bidi-font-style:normal'>open repositories</i></span> are an
indispensable prerequisite for scaling such hypermedia systems beyond the
purposes of one community of practice. Scientific discourses in an informed
society would then not be isolated to the ivory tower. Modern systems should
allow clients of any kind to check out and modify archives and bring them b=
ack
into the discussion again, fostering discourse and simultaneously assuring
intellectual property. We are aware that this is not only a requirement of a
class of systems but that it will be accompanied by the transformation of t=
he
humanities themselves. <o:p></o:p></span></p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>A=
 naive
multimedia understanding - e.g. that hypermedia can transport knowledge -
isn&#8217;t sufficient, as complex interrelations between media exist as we=
ll
as complex cultural interfaces to these media [7]. So, advanced hypermedia
management strategies (<i style=3D'mso-bidi-font-style:normal'><span
style=3D'mso-bidi-font-weight:bold'>fluid archives</span></i>) are a crucial
factor in science and learning processes instead of old-fashioned
de-contextualization strategies propagated in state-of-the-art information
systems.<o:p></o:p></span></p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>L=
earning in
communities of practice needs to bridge the gap between semantic freedom in
(almost) arbitrary metadata annotations, scalable repository technologies a=
nd
fluidity. The success of collaborative hypermedia systems heavily depends on
the discursive nature of knowledge creation. Information systems that assist
cross-disciplinary communities of practice should be able to capture,
visualize, and support the ongoing scientific discourse in order to keep
participants informed and committed to the knowledge creation process. Towa=

this end, we present a case study, using the <st1:place w:st=3D"on"><st1:Ci=

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>T=
he CoP in
this case is composed of people cooperating with our collaborative research
center who are conducting multidisciplinary research concerning facial
semantics in movies. The CoP is physically distributed throughout the
departments of film studies in three German cities. Members of the CoP have
diverse educational backgrounds, e.g. film studies, history of art, graphic=
al
design, and have varying levels of professional experience. The community
members already have different interests and point of views, due to their
educational and cultural background. Their joint enterprise is to analyze t=
he
semantics of facial expression in movies by classification of and comment on
movie scenes in four dimensions: the beautiful face, the dramatic face, the
portrait, and mass faces. By the nature of their research tasks, the commun=
ity
members very often have different points of view on a shared multimedia
artifact, and these differences are expressed through the use of distinctive
vocabularies. When trying to find a common level of communication the commu=
nity
is very often forced to restrict their vocabulary to a minimum or else to m=
ake
use of terms that are irritating to other members having another background=
 or
research focus. One example is the meaning of the term &#8220;text.&#8221; =
An
art historian stated that she would never use the term &#8220;text&#8221; f=
or
movies, while the other members wanted to use the term in the broadest sense
possible.<o:p></o:p></span></p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>A=
 major
aspect influencing the CoP is its distribution among several universities i=
n <st1:place
w:st=3D"on"><st1:country-region w:st=3D"on">Germany</st1:country-region></s=
t1:place>.
For that reason, a collaborative information system and a collective server=
 to
share multimedia files is of great importance to them. Using a collective
multimedia artifact server would not only foster collaboration among
researchers, but it would also enable students to supplement rare on-campus
screenings. Obviously, the knowledge creation process displayed is
discourse-oriented collaboration on the basis of movie samples covering the=
ir
research topic. So, they learn by having screenings together in order to
classify and comment on them. Here, we detected that a crucial aspect of the
CoP was the need for almost arbitrary classification, re-combination, and
annotation features of multimedia artifacts to be made accessible to the
community members. This implies that aspects of <i style=3D'mso-bidi-font-s=
tyle:
normal'>semantic freedom</i> need to be embedded into the system, allowing =
the
almost arbitrary re&#8209;contextualization of multimedia artefacts. Howeve=
r,
another requirement was derived by the demand to protect their individual
property because in research communities the risk of plagiarism should not =
be
underestimated. In addition, another, previously unmentioned, aspect is the
commentary relationship of the media themselves, as information cannot be
regarded as independent from the medium through which it is transmitted. Th=
at
means, a media theory considered as an isolated information carrier of cont=
ent
is not sufficient; the result is the need for a system that carries (at lea=
st)
metadata about the situational context (background) of its own creation.
Nevertheless, metadata only are not able to carry the needed information
without any graphical representation. For that reason, the CoP needed a sys=
tem
expressing semantic relationships between various media artifacts by hiding=
 the
complexity of storing and retrieving the information. To meet the requireme=
nts
of the community we have searched for an alternative to let them express th=
ese
relationships in an understandable and intuitive procedure similar to common
working practices. Therefore, we agreed on an enriched video editing system
tool able to visualize relationships between media. Even the commentary
relationships of media, however, didn&#8217;t resolve the terminological
conflicts after a common classification scheme was created. <o:p></o:p></sp=
an></p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>A=
nother
system requirement of creating individual reference collections was derived
(branched) from the core classification scheme that is common in paper-based
work in the cultural sciences. To progress scientifically, it is necessary =
not
only to externalize individual findings by a classification schema (which is
fine for things such as dissertational work) but also to share and align the
findings with the other members of the CoP in a common classification schema
that promotes the project needs (which is particularly necessary for the
research of facial semantics in movies, independent of the need in general).
Naturally, the views of individuals and the CoP as a whole are often
conflicting, offering innovative potential for research insights and new
research questions. Scientists want to discuss their different point of vie=
ws
and the resulting productive disturbances in the epistemological process.
Furthermore, for writing research papers reflecting the discursive process =
of
knowledge creation, the CoP needs a system that allows the logging and back=
&#8209;tracking
of decisions rendered in the common classification creation process, which
allows for a better understanding of the overall process. The underlying
classification scheme caused such difficulties in interpreting and
understanding the other members&#8217; views on certain aspects that exchan=
geability
and recoverability were other aspects the CoP needed in order to make the
emerging difficulties productive for their continuous learning process. <o:=
p></o:p></span></p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>A=
 major
deficit of existing collaboration systems in the humanities is the restrict=
ive
administration of reference collections. In general, reference collections =
(<i
style=3D'mso-bidi-font-style:normal'>fluid archives</i>) are possible by br=
anching
off from the community archive at a certain point in time. However,
incorporating modifications performed individually or in collaboration into=
 the
previously checked out data set in the system is basically impossible. On t=
he
one hand, existing collections might be refined and rearranged almost
infinitely [2], but don&#8217;t allow the creation of an individual index in
terms of the categorization scheme. On the other hand, systems like WEL [9]
allow users to check out the overall terminology in order to modify the com=
mon
index for individual purposes, but block its re-insertion into the establis=
hed
community-wide system. To allow parallel processing of hypermedia in refere=
nce
collection annotations, categorizations and dependencies can be checked out=
 and
compared for similarities and differences. The visualization of the results=
 is
then a consequent step in supporting the discussion process that makes the =
emerging
difficulties in the semantic capturing productive. It allows user adaptatio=
n of
the underlying classification scheme as well as assigning hypermedia artifa=
cts
to certain categories. Additionally, recovery and loading features are incl=
uded
to exchange and discuss the categorizations within the CoP and to compare t=
heir
development over time.<o:p></o:p></span></p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>T=
he focal
point for collaboration in cultural science communities is a collective
multimedia artifact repository because it represents the basis for all
activities within the CoP. This requirement makes a logical united reposito=
ry
essential. However, this might lead to problems in cases of the CoP having =
only
part-time access to web resources. Personal and group collections can also =
be
used, but here the need for protecting intellectual property and branching =
data
sets in reference collections can lead to conflicts as well. This leads to =
more
or less fine-grained community self-organization issues, particularly in re=
gard
to the protection of intellectual property. This disturbs, somewhat, the th=
eory
of a community of practice, but it is inevitable because of the tendency of
individual researchers to follow their own career plans instead of the plan=
s of
the shared practice. To ensure the intellectual property rights of the
individual members of the community - again, a centralized component - a me=
thod
is needed to identify a CoP as itself, and to identify roles within that
community. Based on the role of a community member within the system, an
individual might be allowed to perform only a limited set of actions or mig=
ht
not be allowed to access all the documents stored within collections. Anoth=
er
aspect is the search and retrieval features to find previous hypermedia
artifacts and the comments pertaining to them not only on the global hyperm=
edia
artifact set, but on shareable group collections as well. Discourses in the
humanities commonly start with research on the results achieved in former
discourses. Following Foucault, we can say that the discourse creates the
things it is talking about. Researchers aim at refining the underlying theo=
ry
that is to be applied to hypermedia artifacts as a result of their discours=
e.
The retrieval and re-contextualization of previous discussion stored in
collections and hypermedia structures is of even greater importance than
before. <o:p></o:p></span></p>

the systems should support the full richness of media usage while making
careful choices about which media-related activities should be captured and

adventure that cannot be scaled over the boundaries of one community of

<h1>1. COMMUNITY-BASED LEARNING IN APPLIED COMPUTER SCIENCE</h1>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>T=
he course
&#8220;High-tech Entrepreneurship and New Media,&#8221; now in its fourth y=
ear
of existence and held at two German research universities, is the result of=
 the
unhappiness of the authors with classical and &#8220;new&#8221; e-learning
teaching efforts in applied computer science at German universities. Among
others, we made three observations that we want to address here: 1) Even th=
ough
many students worked as software developers in local entrepreneurial and
established companies, their practice was not reflected in university teach=
ing
at all. In singular cases the work led to successful joint diploma thesis
projects and excellent job offers. Our idea was to establish a course that
stabilizes the reflection of student practice and to move the newest ideas =
of
software engineering from the university into practice. 2) Local high-tech =
companies,
founded mostly by university graduates, were only loosely linked to their
birth-giving universities. Compared to US universities, the level of
interaction between academia and industry is too low. The innovation potent=
ial
and the needs of the companies are not addressed in a sufficient way. Our m=
ain
idea was to offer entrepreneurs a platform to reflect about their experienc=
es,
to sensitize students for entrepreneurial activities, and to let students w=
ork
on real-world problems instead of fabricated lab examples. 3) The way new
teaching technology is introduced leads to disappointing results in computer
science. Often technologies only mimic classical teaching methods or mask t=
he
pedagogical disorientation in applied computer science between the curricul=
a of
the natural sciences and engineering. Our idea was to apply socio-cultural
theories of learning and identity building [1; 11; 17&#8212;19; 21], follow=
ing
our enquiries of US entrepreneurial education and networks around the MIT (=
Massachusetts
Institute of Technology, Cambridge, MA) area, and suitable collaboration to=
ols
to small connected groups of computer science students working on real world
problems in local companies. <o:p></o:p></span></p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>B=
ecause we
rigorously documented and evaluated the course from its early days until no=
w,
we have a huge amount of data which, for several reasons, we constantly lin=
ked
to the applied theories. On the practical side, we re-designed and adjusted=
 the
course in reaction to the analysis made and the overall dramatic change in =
the
German university teaching system (<st1:place w:st=3D"on"><st1:City w:st=3D=
"on">Bologna</st1:City></st1:place>
process). On a theoretical side, we tried to overcome our na&iuml;ve
understanding of socio-psychological theories [3; 4; 12], especially
communities of practice [2; 10; 20], and to formulate a more realistic
understanding of shared interactions and shared cultures in groups, communi=
ty
and networks [6; 15]. The course design and several evaluations were report=
ed
in various places [8; 9; 13; 14]. Therefore, we will only introduce this to=
pic
very briefly. In this paper, we primarily want to reflect on the long-term
effects our study&#8217;s ramifications may have on students, our teaching
practice, the entrepreneurial networks and technology.<o:p></o:p></span></p>

<h1>2. COURSE STRUCTURE AND IMPLEMENTATION</h1>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>I=
n the
course, several groups of computer science students each work on a concrete
project task for a start-up company. The courses are accompanied by a serie=
s of
lectures in which university lecturers and practitioners present topics
relevant to entrepreneurship and media. The cooperation of students and pra=
ctitioners
in carrying out a common real-world task should allow the establishment of a
shared practice and, therefore, mutual learning. Group-oriented learning
processes, especially among the student teams and between them and their
academic advisors, ought to be facilitated by a community system. Thus, the
instructors put task-relevant learning materials on the community system.
Moreover, it was supposed to work as a forum of discussion among students a=
nd
guest lecturers from industry and academia. The system supported cooperation
within and between working groups. Additionally, it has been used as an arc=
hive
for lecture and project materials. <o:p></o:p></span></p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>I=
n the
first meeting, the students interested in the course were introduced to the
basic concept of this type of courses; the tasks were presented briefly and
project groups were formed. The students then chose one of the presented
project tasks and formed appropriate working groups. Following this, studen=
ts
took an intense two-day tutorial on software engineering methods, project
management techniques and other relevant issues. The students had meetings =
with
their start-ups in order to gather information about their objectives, proj=
ects
and working methods. The project groups and tutors compiled and agreed upon
concrete project aims for the execution of the practical tasks, and a reali=
stic
project plan that was to be examined in the first review. With regard to the
accompanying lecture, speakers from academia and practice rotated. The stud=
ents
got perspectives from management consultants, venture capitalists, software
developers, and personnel specialists, who supplied topic-referred empiric
reports and were available for discussions and critical inquiries. In the
reviews, the project groups mutually presented each other their results and
discussed the further procedure together with the lecturers and experts. Th=
ese
review sessions also served to exchange experiences and offered the possibi=
lity
of one group benefiting from the progress and findings of another project g=
roup.
At the end of the term, students, lecturers, and entrepreneurs had a final
meeting. The project results were presented by the project groups and
discussed.<o:p></o:p></span></p>

<h1><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>3. EVALUATION METH=
ODS<o:p></o:p></span></h1>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>T=
he authors
follow the idea developed by Gerry Stahl that community-based learning shou=
ld
be analyzed at the intermediate level of small groups of individuals within=
 the
community [16]. Therefore, we mainly observed the performance of the studen=
ts
within the groups. The materials were created, collected, and analyzed by
advanced students of psychology under the supervision of a trained
psychologist. We used different qualitative methods for the enquiries: 1) t=
he
lecturers composed several lecture analyses, which stated progress, discuss=
ion
with students, and other characteristics. For extern lecturers, these proto=
cols
were composed by university members; 2) explorative semi-structured intervi=
ews
with students and supervisors from academia and industries were conducted. =
All
interviews have been recorded with DAT-recording and fully transcribed. In =
the
evaluation, the answers were transformed into a table categorized by the ro=
le
of students and academic and entrepreneurial supervisors. The interviews ha=
ve
been analyzed descriptively; 3) interaction within the community-system was=
 recorded,
as was email-exchange between students and their cooperation partners in the
start-ups; 4) as part of the final arrangement and subsequent to the
presentation of the project results, a 45-minute open discussion took place
between students, lecturers, and cooperation partners from the start-ups, w=
here
students especially were asked to give feedback concerning the concept and
structure of the lectures. The course of discussion was recorded.<o:p></o:p=

hese four
types of networks are not independent from each other. For balancing lock-in
syndromes, transactional openness, value injection, trust, and solidarity a=
ll
four kinds of social networks are needed. If we assume that the situation in
the Boston region is far better than in Germany, and if we assume that we c=
an
improve the situation locally by fostering learning among students and among
other members in the network, we can analyse what our impact was and is. We
have reported elsewhere about design flaws and practical problems in the co=
urse
and how we dealt with them. Here, we want to concentrate on the question: <=
/span><i
style=3D'mso-bidi-font-style:normal'>Did the students learn how to network?=
</i> </p>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>W=
e know
from our study of entrepreneurial networks in <st1:place w:st=3D"on"><st1:C=
ity
 w:st=3D"on">Boston</st1:City></st1:place> that newcomers have only faint i=
deas
about networks and networking, but experienced players know how to make use=
 of
social capital in the networks. The CoP between the students can be compared
with peer group effects found in the MIT study. Students within the groups
build up social capital (or not) leading to relationships beyond the scope =
of
the course. Still, the lab students do joint work in other contexts like co=
urse
homework or master thesis work. </span>We can monitor that the students sti=
ll
use the community system, especially for downloading materials not stored
elsewhere, like taped videos of the review sessions and personal information
about other lab members. <span lang=3DEN-GB style=3D'mso-ansi-language:EN-G=
B'>Some
of them have the same cultural background, but we can also observe cooperat=
ion
between students from different countries but the same year. The group
structure was developed, self-organised and described as non-hierarchical. =
</span>Most
important, the barriers for the establishment of a CoP between university
students and start-up companies are limited resources (time and persons) and
cultural differences. The differences, especially in cultural background and
historical experiences, between the &#8220;student&#8221; and
&#8220;entrepreneur&#8221; groups might make processes of social identifica=
tion
more difficult, and therefore successful community-building less likely. <s=
pan
lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'><o:p></o:p></span></p>

<p class=3DMsoNormal>Nevertheless, good personal relationships and rich soc=
ial
capital were established between some students and practitioners. Self-orga=
nized
and non-hierarchical structures supported the building of social capital wi=
thin
the groups. In all groups, learning mechanisms of legitimate participation =
proved
successful, especially if the students reported on high-intensity learning =
as
part of their collaborative practice in the groups. In particular, a Thai
student in the third instance of the course at RWTH Aachen was asked to pre=
pare
her master&#8217;s thesis in computer science for the very same company with
which she did the course project. Moreover, her mate was also able to get a
thesis topic in the company. In such situations it is hard to analyze to wh=
at
extent the reputation building process of the course has contributed to the
final result. We see this as an indicator that we were successful in
establishing networks of reputation in the region (type 3).</p>

<p class=3DMsoNormal>The personal reputation of the supervisors from the
university within the entrepreneurial networks has been leveraged by the
courses. The supervisors are included in information exchange networks and =
are
invited to start-up related events like business plan competition, company
fairs and so on. In particular, the contact between the course supervisors =
and
the local university entrepreneurship center from which lecturers were invi=
ted
to present in the course lecture series helped to establish stable relation=
ships
and social capital within the reputation network of the high-tech/new media
cluster (type 3). </p>

<p class=3DMsoNormal>The events are part of type 1 networks, which foster i=
nitial
matchmaking and reduce risks of cold calls by opening informal meeting
opportunities. Seldom, if ever, do computer science master student visit th=
ese
events. Most of the attendees from the university are PhD students or alumn=
i.
This is very different from the situation around MIT (add to that the fact =
that
the number of events is a magnitude higher in <st1:place w:st=3D"on"><st1:C=
ity
 w:st=3D"on">Boston</st1:City></st1:place>). The use of social capital in t=
his
network type is thus limited. To overcome this situation, students should be
motivated to visit these events on a regular basis. </p>

<p class=3DMsoNormal>The fourth network type is very different in the <st1:=

 w:st=3D"on">Germany</st1:country-region></st1:place>, due largely to diffe=
rent
legal regulations concerning intellectual capital and a different venture
capital culture. Intellectual capital issues were raised selectively in the
course, but it never approximated the signature of a non-disclosure agreeme=
nt
like it was usual to do in the entrepreneurship lab at the MIT Sloan School=
 of
Management. Furthermore, the start-up representatives never discussed serio=
usly
with the students the role of intellectual capital and the possibilities of=
 an
actual start-up. Neither side was very experienced in these topics due to t=
he
non-existence of a comprehensive entrepreneurship curriculum at the univers=
ity.
No real money was on the table, thus the use of intellectual and social cap=
ital
in this network type was not comparable to the situation found in <st1:place
w:st=3D"on"><st1:City w:st=3D"on">Boston</st1:City></st1:place>. But both t=
he
handling of intellectual capital and the venture capital culture has changed
dramatically during the past several years in the direction of US-type
regulation. Intellectual capital handling by the university has become much
tougher over the last year, and always includes royalties for university
inventions made in such courses. </p>

<p class=3DMsoNormal>To conclude, we can say that the type 2 and 3 networks=
 are
being supported by the course directly but because of regional differences =
the
support for type 1 and 4 networks can be leveraged in the future. This is
important because type 1 and 4 networks can prohibit members of type 2 and 3
networks from social and cognitive lock-in situations. First, we provide a
general openness of the network for newcomers. Second, we ground actions in=
to
reality. To follow the careers of students we need to install a long-term
monitoring system which allows us to keep track of the student&#8217;s
development. This should be a function of the community system that is in
place.<b><o:p></o:p></b></p>

<h1>1. OVERVIEW</h1>

<p class=3DMsoNormal>Modern western societies are facing the challenges of
immigration and integration. The main criterion for social participation an=
d democratic
collaboration is the successful integration of immigrants. A lack of social=
 as
well as cultural integration, especially among young immigrants, seems to be
the consequence of a low level of education and unequal opportunities. Immi=
grant
children who are enrolled at primary schools, for instance, show significant
deficits in tests of German language acquisition in comparison to German pu=
pils
on the one hand, and even to other immigrant pupils of their parent&#8217;s
generation, on the other.</p>

<p class=3DMsoNormal>Moreover, corresponding to this drop of linguistic
competence, the social gap seems to be growing along the so-called digital
divide. Thus, in the last years, several attempts have been initiated to en=
able
underprivileged social groups to access computers. The concept of Computer
Clubhouses (CCH) is of special interest in this regard.</p>

<p class=3DMsoNormal>Motivated by discussion about the concept of the CCHs =
and
the theoretical learning approach of the Communities of Practice (CoP), the=
 concept
for the intercultural computer club Come_IN has been developed and put into
practice. This year it has been opened officially in &#8220;Bonner
Altstadt,&#8221; one of the city of <st1:place w:st=3D"on"><st1:City w:st=
=3D"on">Bonn</st1:City></st1:place>&#8217;s
multicultural neighborhoods. Come<i style=3D'mso-bidi-font-style:normal'>_<=
/i>IN reframes
the concept of the CCH to fit the German context. </p>

<h2>1.1. The Bonner Altstadt Neighborhood</h2>

<p class=3DMsoNormal>Come_In has been built up in cooperation with St. Mari=
en, a
catholic elementary school in the neighborhood. The school implements the a=
ims,
values and methods of the reform-minded pedagogical learning paradigms of M=
aria
Montessori. The school is considered exemplary in realizing innovative
pedagogically didactical practice. The curriculum focuses on open- and
work-oriented lessons, e.g. in small groups, workshops, and projects. Each
classroom is equipped with two or three computers that can be used as resou=
rces
in the daily work. For more than a decade, pupils are taught in classes with
mixed age-groups. The pupils of the St. Marien School come from very differ=
ent
social and cultural circumstances. About 35% of all pupils are of Turkish
origin and have been poorly educated. There are a considerable number of ot=
her
immigration children as well. </p>

<p class=3DMsoNormal>The district where the project takes place has a popul=
ation
of about 10,000 inhabitants. The social and cultural structure of this dist=
rict
can be characterized as a colorful mixture of different communities<a

Today&#8217;s situation in the quarter is a result of post-war urban
development. In the 60s and 70s, many better-off inhabitants moved away and=
 the
housing conditions deteriorated. Later, they were replaced by people search=
ing
for new and cheaper accommodation, namely immigrants and students. Some
statistical data characterize this situation today: the quarter has a high =
rate
of immigrants (22.7% of the population of the district, compared to 12.5% o=
f <st1:place
w:st=3D"on"><st1:City w:st=3D"on">Bonn</st1:City></st1:place>&#8217;s total

and 32% of those employed are workers).</p>

<h1>2. COMPUTER CLUBHOUSE APPROACH</h1>

<p class=3DMsoNormal>Initiated in 1993, the concept of Computer Clubhouses =
was
put into practice. In cooperation with the former <st1:place w:st=3D"on"><s=
t1:PlaceName
 w:st=3D"on">Computer</st1:PlaceName> <st1:PlaceType w:st=3D"on">Museum</st=
1:PlaceType></st1:place>,
the MIT Media Laboratory opened the first computer club for young participa=
nts
coming from a lower-class background with a low level of education. The
pedagogical concept is an extension of the constructivist learning paradigm=
. In
constructivism, learning is a process of constructing individual cognitive
structures. Papert extends this idea by stating that these cognitive struct=
ures
have to be put into practice by constructing artifacts [7]. Thereby, a way =
is
found to externalize implicit and tacit knowledge. This is called
constructionism [7]. Furthermore, Chapman argues that the artifacts need to=
 be
put into social context [1]. By doing so, they can be shared with and criti=
qued
by others. Other learners are able to learn from and with the artifacts, wh=
ile
the constructor learns from those dealing with the artifacts. Shaw enriches=
 this
theory with a socio-cultural aspect indicating that constructional learning=
 is
also social learning [10]. Besides the artifacts themselves, social connect=
ions
are built into the process of constructional learning. As a result, social
capital is part of the underlying concept of the CCH. Highly innovative ICT=
 is
used to stimulate the learning process of the target group at short notice.=
 From
a long-term perspective, the CCH tries to provide better access to working =
life
for the youth [8; 9]. </p>

<p class=3DMsoNormal>The core principles of the clubhouses are as follows: =
a) to
support learning through design experiences; b) to help youth to build on t=
heir
own interests; c) to cultivate an &#8220;emergent community&#8221;; and d) =
to create
an environment of respect and trust [9]. Hayes et al. demonstrate the
difficulties of bringing this espoused model of the CCH into practice [4]. =
That
team also shows how it collides with the actual needs of its members.</p>

<p class=3DMsoNormal>Communities of practice (CoP) are an interesting way of
explaining learning and knowledge acquisition processes [6; 12]. This idea
follows from socio-cultural learning theories, which understand learning as=
 a
collective process. This process is linked to specific contexts of action.
Learning in a CoP is defined by the relationship of groups of <i
style=3D'mso-bidi-font-style:normal'>old-timers</i> and <i style=3D'mso-bid=
i-font-style:
normal'>newcomers</i> that are inside the community. By means of legitimate
peripheral participation, newcomers are confronted with the practice of
old-timers, which built the core of a CoP. This situation has some similari=
ties
to the principle of cultivating an emergent community in the CCH. </p>

<p class=3DMsoNormal>As newcomers interact, work, and communicate with old-=
timers,
their experiences increase. This phenomenon indicates that learning in a Co=
P is
a process of growing into the community. Furthermore, CoPs are characterize=
d by
common conventions, language, tool usage, values, and standards. A CoP is
inseparable from issues of (individual and social) identity. Identity is ma=
inly
determined by the negotiated experience of one's self in terms of participa=
tion
in a community and the learning process concerning one's membership in a Co=
P [12].</p>

<h1>3. INTEGRATION AND THE ROLE OF ICT</h1>

<p class=3DMsoNormal><span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>T=

can lead to the condition that both parents and children acquire too little
linguistic and intercultural competency to communicate with members of other
communities.<span lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'><o:p></o:p=
></span></p>

<p class=3DMsoNormal>In the following sections, we will focus on the role o=
f ICT.
Because we deal with social phenomena like integration and communication, t=
he
perspective on this role is more socially oriented than in traditional
approaches. To make our argument easy to follow, we present a broader but
simplified view of ICT to the reader. Of course, such a view does not pay f=
ull tribute
to the complexity of the topic:</p>

<h2>3.1. <st1:place w:st=3D"on"><st1:PlaceName w:st=3D"on">Cross</st1:Place=
Name> <st1:PlaceName
 w:st=3D"on">Community</st1:PlaceName> <st1:PlaceType w:st=3D"on">Building<=
/st1:PlaceType></st1:place>
and Intercultural Learning</h2>

<p class=3DMsoNormal>From a superficial perspective, the problem described =
above
is a problem of a lack or a gap in education. So, in a terse manner, the
problem would be easy to solve if computer programs transferred knowledge, =
and
thus, filled the gap in education. However, considering socio-cultural lear=
ning
theories, it seems obvious that the source of the problem lies deeper &#821=
1;
namely on the level of identity. In <st1:place w:st=3D"on"><st1:country-reg=
ion
 w:st=3D"on">Germany</st1:country-region></st1:place>, over the years Turki=
sh
immigrants developed and stabilized functional and self-organized ethnic
communities, which formed their own identity separated from other communiti=
es [3;
11]. These communities have their own traditions, due largely to the fact t=
hat their
community parameters (such as cultural and social values and language) are =
at
most only weakly influenced by the parameters of other communities. For many
within these communities, there seems to be no need to interact with other
communities at all. From our point of view, the main challenge for integrat=
ive
work in society is to establish additional identities besides those of the =
different
ethnic communities. These identities should to be built on shared practices.
While learning by doing, the members of these intercultural CoPs will reali=
ze
integration through unintended motivation.</p>

<h2>3.2. Participation of Parents in the Learning Process</h2>

<p class=3DMsoNormal>We assume that the participation of more than one gene=
ration
in computer-supported project activities will encourage intercultural
communication. The more generations that are involved in this process, the =
more
likely it will appear that socio-cultural and linguistic barriers can be
surmounted, as experiences of numerous generations can build up a richer co=
mmon
identity. Besides that, one specific insight from the practical context of =
the
primary school St. Marien is that targeting only the children of immigrants=
. This
obstruction of the learning process is possibly based on the parents&#8217;
disinterest in schooling, in both its practical and theoretical classes. Th=
ere
is a gap in social learning that cannot be solved by increasing the intensi=
ty
of only classical schooling. The process of integration has to be considered
integrally, which means that parents (as they are part of the social contex=
t)
have to be included. By doing so, socio-cultural learning is fostered. As a
further result, participation allows the parents to benefit from their
children&#8217;s learning progress. </p>

<h2>3.3. ICT as a Door Opener into the Communities of Immigrants</h2>

<p class=3DMsoNormal>So far, we mainly discussed the social environment in =
which
we want to use computers to foster integrative community processes. However=
, we
did not answer one important question: Why does ICT (for our purposes,
computers) play an important and highly specific role in the process of
integration? To answer this question, we want to explain the role of comput=
ers
by drawing an analogy to the implementation of a corresponding development =
aid<a
style=3D'mso-footnote-id:ftn8' href=3D"#_ftn8" name=3D"_ftnref8" title=3D""=
><span
class=3DMsoFootnoteReference><span style=3D'font-size:9.0pt;mso-bidi-font-s=

mso-fareast-language:EN-US;mso-bidi-language:AR-SA'>[8]</span></span><![end=
if]></span></span></span></a>
project. The comparison between integration work and development aid is
justified, as both deal with the problem of how a modernization process can=
 be
promoted from the outside of a community.</p>

<p class=3DMsoNormal>The underlying purpose of the development aid project =
was to
teach female Tunisian farmers the capability of western cattle owning and
breeding techniques [2]. But besides the transfer of pure technical knowled=
ge
(know-what and know-how), there was also a focus on the transformation of
identities that were linked to the technology. By doing so, the learning was
supposed to become a sustained progress. Dersch describes the structure of =
this
transformation as follows: </p>

<p class=3DQuote style=3D'margin-right:.5in'>[It] shows that the transforma=
tion
process takes place on two different levels and at different speeds. Modern
technical, economic or institutional innovations are more quickly and easily
adopted by a traditionally oriented culture than are changes in normative
behaviours and social attitudes [2].</p>

<p class=3DMsoNormal>The characterizing role of technology in this transfor=
mation
process lies in its ability to integrate people from foreign communities in=
to
the process of technical knowledge acquisition.<span style=3D'mso-ansi-lang=
uage:
EN-GB'> <span lang=3DEN-GB>This opens opportunities where a <i style=3D'mso=
-bidi-font-style:
normal'>common working </i></span></span><i style=3D'mso-bidi-font-style:no=
rmal'>practice
-</i> which is related to a specific technology - can be transferred to a
community of practice. In this respect, the concept of the CCH is turned up=
side
down: <i style=3D'mso-bidi-font-style:normal'>The existence of a community =
is not
necessarily obligatory to start learning processes. Rather it is the other =
way
round. The motivation to acquire technical skills can be used to set cross
community processes in motion. </i>However, community building is a social
process, so it is not guaranteed that a common interest in technology will =
lead
to a community of practice. But, we believe that the learning process will =
be
sustained if the transformation from common practice to a community of prac=
tice
succeeds.</p>

<p class=3DMsoNormal>When we transfer this insight to the concept of <i
style=3D'mso-bidi-font-style:normal'>come_IN</i> we can show that ICT can f=
ulfill
the role of an attractor or motivator for participation. Motivation to learn
about computers functions as some sort of entrance card or an impetus for t=
he integrative
transformation processes.</p>

<h2>3.4. The Come_IN Project</h2>

<p class=3DMsoNormal>Based on the considerations presented above, we develo=
ped
the concept of an innovative computer club. In cooperation with the element=
ary
school it became possible to put this concept into practice. In addition, by
examining the workings of the club we were able to get first insights into =
its
potential.</p>

<p class=3DMsoNormal>After a preparation period of 18 months, the Come_IN
computer club was opened officially in March 2004. Since its opening, it has
been running each Wednesday from <st1:time Hour=3D"17" Minute=3D"0" w:st=3D=
"on">5pm</st1:time>
to <st1:time Hour=3D"19" Minute=3D"0" w:st=3D"on">7pm</st1:time>. The inten=
ded target
groups show strong interest and active participation in the club. The
successful start of the club is mainly based on the work of several volunte=
ers
from the district. With the help of several donations it became possible to
obtain initial hardware and software equipment. Again, the support for the
project groups is mainly provided by volunteers from the quarter. </p>

<h2>3.5. Children Together with Parents</h2>

<p class=3DMsoNormal style=3D'mso-layout-grid-align:none;text-autospace:non=
e'><span
lang=3DEN-GB style=3D'mso-ansi-language:EN-GB'>Education is not only a publ=
ic
affair. Parents have to care about the education of their children, as well=
. Schools
and parents should work together to promote the learning of their children =
[5].
Improving this cooperation and integrating parents into the schoolwork of t=
heir
children was one of the major reasons the elementary school was interested =
in
participating in this project.<o:p></o:p></span></p>

<p class=3DMsoNormal>Thus, as a rule, a child may only come to the club if
accompanied by at least one of her parents. This regulation ensures the
inclusion of parents with the learning process of their children. Children
learn from parents and vice versa. In addition, it is hard for elementary
school kids to manage complex projects themselves. So, opportunities are gi=
ven
to the parents to realize their own ideas. Foreign and German parents
communicate with each other. Again, the computer plays an important role in
this process as it builds the fundament of shared practice in the club
community. Especially in the Turkish community, it is seen as an opportunit=
y to
achieve (further) social success.</p>

<h2>3.6. Working on Projects</h2>

<p class=3DMsoNormal>Current topics, latest news and daily problems influen=
ce the
establishment of new projects. Relevant topics are put into local and regio=
nal
contexts to provide a platform for a multicultural dialog. Mainly
socio-cultural and ecological questions that influence the pupils&#8217;
everyday life and their experiences are discussed. As a first project focus=
 in Come_IN<i
style=3D'mso-bidi-font-style:normal'>,</i> a multi-media documentation of a
multicultural family history of the quarter is set up. Right now, the third
generation of Turkish immigrants lives in the district, which emphasizes the
motivation for this project. The goal is the creation of a shared multicult=
ural
history. Especially the first generations of immigrants, who came to <st1:p=
lace
w:st=3D"on"><st1:country-region w:st=3D"on">Germany</st1:country-region></s=
t1:place>
as guest workers and have collected a lot of experiences, have local intere=
sts
that have not yet been documented at all. This German-Turkish history shall=
 be
set into contrast with the German family histories in the district. So, the
project will help to create a common practice that has a shared history. Su=
ch a
shared history may support the growth of a shared identity across the diffe=
rent
communities. Naturally, success can only be achieved by involving all
generations and all ethnic communities. The result of the project will be a
collection of multi-media materials that will be the common ground for furt=
her
exhibitions. </p>

<p class=3DMsoNormal>Learning in this context does not appear in a behavior=
ist
manner, but more likely through a process of constructing. Supported by
computers, all participants in the project get the opportunity to search for
historical and social sources within their personal context. Others may lea=
rn
from the resulting artifacts. Based on an emergent common identity, it is
possible to reduce prejudices (yet, we assume that this already happens dur=
ing
the process of constructing). As a result, integration in this context is n=
ot a
social utopia but the product of common and shared practice that includes
respect and comprehension.</p>

<h2>3.7. Playful Acquisition of Computer and Media Skills and Competences</=
h2>

<p class=3DMsoNormal>By the playful computer-supported acquisition of media
competences, participants learn how to work practically with innovative too=
ls
in a natural manner. This naturalness will allow both the children and their
parents to master new challenges more easily. It provides occupational chan=
ces
for the children in the future whereas parents may achieve further social
development and participation in their social life. Furthermore, children g=
et
the chance to explore their own interests. They will externalize these
interests by constructing multi-media artifacts, which again may help other=
s in
their own learning process. Intercultural barriers will be surmounted. This
effect, plus the attraction of computers and new media, will safeguard the
survival and further success of the computer club.</p>

<h1>4. THE FUTURE</h1>

<p class=3DMsoNormal>Actually, the current state of Come_IN must be seen as=
 a
success. One indicator for that is the high rate of participation from the
German and the Turkish community. But, for a deeper and more precise evalua=
tion
it is still too early. We will examine the future progress of the club with=
 the
help of ethnographical studies over a longer period. The results will be the
basis for the further development of the concepts. With regard to the common
practice within the club, an evaluation will have to deal with the following
issues:</p>

<h1>1. INTRODUCTION</h1>

<p class=3DMsoNormal>Distance Education (DE) is becoming increasingly impor=
tant
as its rapid growth rates demonstrate. However, recent statistics on DE show
low retention rates and a poor return on investment (ROI) in various progra=
ms. We
need a better understanding of what are the critical success factors for DE
environments for all constituencies (students, instructors, and institution=
s).
We still misinterpret the reality of this kind of practice, both from the
teacher&#8217;s and the learner&#8217;s point of view [1]. In this article,=
 we
focus on the collective dimension of the learning environments. In fact,
entering a virtual learning community appears as a rational choice for the
students to retrieve information more rapidly [3] and examine with available
peers the actual content. But, students occasionally express a natural anxi=
ety
about sharing their difficulties with strangers, which partially explains t=
he
barriers in establishing trusting and caring learning communities [2].
Well-sequenced pedagogical courses and frequent contacts with the professor
seem to strengthen the cohesion and integration of the students in a group.
Consequently, educational choices and the global architecture of the course=
, by
influencing the formation of these groups, try to compensate &#8212; at lea=
st
partially &#8212; for the deficiencies of DE. The goal of this paper is to
propose solutions to overcome low retention rates and ROI in order to deplo=
y an
efficient DE program using the key solution of a web-based course in an Ame=
rican
public university.</p>

<h1>2. METHODOLOGY</h1>

<p class=3DMsoNormal>To collect the data for this study, we interviewed stu=
dents
enrolled in an introductory MIS course taught exclusively online. Each
semester, over 1200 students register for this 16-week course. They learn a=
bout
management of information systems and Microsoft Excel. The students were pl=
aced
in sub-groups of 30 members to recreate a classroom environment and facilit=
ate
emerging learning communities. The professor enforced strict rules with reg=
ard
to this course, including assignment posting in discussion groups every oth=
er
week and numerous Excel / MIS exams. To reduce student requests, a &quot;<i
style=3D'mso-bidi-font-style:normal'>three before me</i>&quot; rule was
established: to question the professor, students must have first tried to g=
et
answers for their question in three other ways (syllabus of the course,
discussion group, chat with a peer).</p>

<h1><span style=3D'mso-spacerun:yes'>&nbsp;</span>3. OBSERVATIONS</h1>

<h2>3.1. Group Discussions are not Utilized Effectively</h2>

<p class=3DMsoNormal>Discussions groups have not been utilized effectively.=
 Each
sub-group had its own discussion group<b style=3D'mso-bidi-font-weight:norm=
al'> </b>(discussion
group 1,2,&#8230;,40). Students had to post answers to their assignments in
this location. Access to these forums was restricted to the 30 members.
Additional forums were made public by the professor including:</p>

<ul style=3D'margin-top:0in' type=3Ddisc>

 <li class=3DMsoNormal style=3D'margin-top:3.0pt;margin-bottom:3.0pt;mso-li=

     Support - </b>a forum utilized to post questions regarding any technic=
al
     problem encountered during the course.</li>
</ul>

<p class=3DMsoNormal>The group discussions, the most adequate place to deve=
lop a
sense of community, were not utilized. The only messages posted in these fo=
rums
were replies to assignments. These groups were rarely used to ask questions=
 to
other students. As Celina mentioned: &quot;<i style=3D'mso-bidi-font-style:=
normal'>There
really was </i>no posting<i style=3D'mso-bidi-font-style:normal'> in our gr=
oup as
far as problems: there is only one posting</i>.&quot;</p>

<p class=3DMsoNormal>Most of the messages posted in the sub-group discussio=
ns
were assignments or forced replies to other students. When they needed to a=
sk
questions students used the Technical issues and Excel support discussion
groups. Consequently, the discussions on these two forums were not focusing=
 on
Excel or Technical Issues, but on any problem that the students might have
encountered (Figure 1).</p>

<h2>3.2. Redundant Messages</h2>

<p class=3DMsoNormal>Messages posted in the discussion groups were simple a=
nd
could be easily answered by the students themselves if they would read the
content of other members' postings. Messages posted in the discussion groups
and interviews clearly demonstrate aggravation from students whom have read=
 the
content provided in the course. Yet, the worst aspect of these redundant
messages was the confusion they created for certain students. Paula argued =
in
the Excel issue discussion group: &quot;It is frustrating to hear the same
questions over and over. I wonder though if there is confusion on this one
because the course reminder keeps showing &#8216;News&#8217; with subtitle =
&#8216;one
quiz must be submitted soon&#8217;, even after exam one is taken?&#8221;</p>

<p class=3DMsoNormal>Instructions and answers for this question could be ea=
sily
found by the students on the course pages, but the number of redundant mess=
ages
triggered confusion. Learners did not realize that posting a message without
reading others was rude and is comparable to asking the same question over =
and
over in a traditional classroom setting. In a traditional educational
situation, this would not be tolerated. It is an accepted part of flounderi=
ng
online communities, as it was in the case of our course. In fact, prior
research has indicated: &quot;norms that lead to good online etiquette are a
stepping-stone to social capital&quot; [4]. Consequently, students lost
confidence in the question/answer system that was not providing them with t=
he
desired response. Questions accumulated in the technical and Excel question
forums and discussion groups.</p>

<h2>3.3. Absence of Community</h2>

<p class=3DMsoNormal>The lack of community and trust was evident during
interviews. Students did not utilize the help from others in their ISM grou=
ps.
They chose to go out of the course to find peer support (friends, co-worker=
s).
In fact, they were reluctant to interact with the professor following
guidelines (three before me rule), and did not want to post in the intimida=
ting
large discussion groups. One student actually mentioned: &quot;<i
style=3D'mso-bidi-font-style:normal'>basically, I know one thing this class
taught us is how to network </i>&quot;<i style=3D'mso-bidi-font-style:norma=
l'>.</i>
To succeed in this course, learners had to organise themselves in study gro=
ups:
&quot;<i style=3D'mso-bidi-font-style:normal'>Every Friday, we meet up in t=
he
Magruder lab, and we start to go over the Excel and Assignment</i>&quot;
(Lucetta L.).</p>

<h1>4. ANALYSES</h1>

<p class=3DMsoNormal>Discussion participation and student interviews clearly
indicate the necessity to update our pedagogical method. We ought to find in
existing online communities technical and organizational solutions. In this
part we are going to consider the concept of learning communities from an
examination of best practices. At first sight and from a purely structural
point of view, the pedagogical approach that we observed at UCF is similar =
to
that of a learning community. To be precise on this point, we can say that =
in a
&quot;<i style=3D'mso-bidi-font-style:normal'>community of practice</i>&quo=
t;<i
style=3D'mso-bidi-font-style:normal'> </i>partnership refers to tacit knowl=
edge
combined with considered practices and associated with purely professional
problem-solving activities. On the contrary, in a &quot;<i style=3D'mso-bid=
i-font-style:
normal'>learning community</i>&quot; exchanges among members revolve around
explicit knowledge that is restricted constantly in a given domain. These a=
re
exactly the objectives of the community we studied. It is designed to learn
about Excel and to construct operational knowledge associated with this too=
l.
But before going any further let us observe the elements which make up a
learning community. </p>

<p class=3DMsoNormal>When a group of people has become a community they dis=
play a
caring attitude with regard to each other [4]. Here, it is useful to mention
that this type of behavior does not appear so much on the forum as in the
direct exchanges between the students. The students who attend the classes =
are
required by the teaching module to ask two questions in the forum and likew=
ise
to respond to two of the questions asked by their fellow students. If the
purpose of this requirement is to prime the pump and launch discussion, it =
has
a perverse effect in regard to group dynamics and the underlying learning
processes. In effect, if the rules are to ask and respond to two questions,=
 why
go any further? In fact, the teaching module requirements obliterate the
learning dynamics at the heart of the community. An analysis of the exchang=
es
on the forum do not exhibit features of co-operation or caring, which are
considered to be essential characteristics of learning communities, except =
in a
watered down, artificial manner. </p>

<p class=3DMsoNormal>The most significant point about this was revealed dur=
ing
student interviews where many of them explained that they had arranged to m=
eet
frequently and regularly both on and off campus. For example, those who liv=
ed
far from the university would plan to meet in the local public library to
discuss their difficulties, find solutions to their problems and help out o=
ther
members of the group. Others told us that they regularly asked their friend=
s or
members of their family more familiar with Excel to find answers to their
questions and then shared the information with other members of the group. =
In
other words, the &quot;community&quot; was created outside the established =
learning
module tools because these were considered too inflexible. </p>

<p class=3DMsoNormal>Members of these groups also told us that they had pre=
ferred
to stay in touch and exchange information using their own electronic
communication tools. Therefore, it seems that communities were created outs=
ide
of the learning module and without utilizing the communication tools provid=
ed.
In our opinion this phenomenon illustrates the difficulties of managing
interactions &quot;mechanically&quot; between members of a community. It se=
ems
that to impose too rigid a regulatory model on a learning community will da=
sh
any nascent spontaneity. </p>

<p class=3DMsoNormal>This is related to the more general question concernin=
g the
directing or managing of communities and the associated pedagogical
&quot;devices.&quot; On this point, and more specifically concerning
communities of practice, Wenger says, &quot;<i style=3D'mso-bidi-font-style=
:normal'>Just
because communities of practice arise naturally does not mean that
organizations can't do anything to influence their development</i>&quot; [6=
]. Gu&eacute;rin
comments on this saying that, &quot;<i style=3D'mso-bidi-font-style:normal'=
>Wenger's
argument is itself potentially contradictory, in wanting to preside over the
fate of a spontaneous phenomenon</i>&quot; [5]. We can represent the
pedagogical implication in a learning community by a triangle whose points
represent respectively, the community (the group), the learner (a student),=
 and
the person who facilitates the encounter between the subject to be learned,=
 the
student and the group (a teacher). The subject to be learned sits at the ce=
nter
of the triangle. We noticed little communication both within and between
groups, and that the students rarely interrogated the tutor (respecting the
rule of &quot;three before me&quot;). In the end, we observed a rearrangeme=
nt
of the pedagogical structure and its technological tools outside the formal
framework of the institution. This is indicated in our schema by the dotted
lines connecting the learners with their peers (friends, family, etc.), who
replace the original tutor or professor (Figure 2). The rearrangement of the
central, social links of the learning community results in the emergence of=
 ad
hoc groups at the heart of the community from the very beginning and, in
addition, the perimeter of these groups <!--[if gte vml 1]><o:wrapblock><v:=

<h1>5. RECOMMENDATIONS</h1>

<p class=3DMsoNormal>The pedagogical organization of this course is
deterministic. Spontaneous student activities were difficult to express. The
students did not have the right virtual environment to meet using the techn=
ical
tools provided. Clearly, the structure of the course, the strict guidelines
students had to follow and the heterogeneity of the student body prevented
learning communities from emerging. We recommend a better organization of o=
ur
discussion groups to take advantage of our diverse student body. </p>

<p class=3DMsoNormal>At the beginning of the semester, students had to comp=
lete a
practice quiz to access the first module. This first evaluation should be u=
sed
to assess the level of our students. Instead of asking twelve similar
questions, we suggested ten website related questions, ten MIS related
questions, and ten Excel related questions. This test should be administere=
d in
the &#8220;add and drop&#8221; period. The result of this test would help us
better segment students in categories: regular users and power users. The
number of power users should be divided by the number of groups. Then these
power users should be placed equally in each sub-group. The rest of the
students should be added in the various discussion groups. This recommendat=
ion
relies on the belief that caring among users is necessary and
&quot;contagious&quot; [4]. We believe that students, if provided with the
correct incentives, will help and care for each other. </p>

<p class=3DMsoNormal>After grading the pre-test, we identified the power us=
ers.
Part of the grading for this course included posting MIS related responses =
and
replies to two other students. The power users could then be offered the
following trade: instead of participating in the discussion groups by
responding to other students, they had to help others in their group to pro=
vide
technical answers. At the end of the semester, if the other students
participate in the discussion groups, the power user will be rewarded
accordingly. We believe that certain behavior is contagious: the fact of se=
eing
power users help other students will cause learners to be inclined to
participate and help their peers.</p>

<p class=3DMsoNormal>This proposition suggested that the two discussion gro=
ups
(Excel Issues and Technical Issues) be disabled. In effect, we wanted to
concentrate the discussions/questions that might arise from students to the=
ir
individual discussion groups only. This should tentatively help us to avoid=
 the
propagation of unnecessary messages in public discussion groups. Yet, we mi=
ght
observe similar questions within different discussion groups. We enjoyed in=
 the
past when students replied to other&#8217;s questions in the &quot;largest
audience&quot; discussion group, <i style=3D'mso-bidi-font-style:normal'>i.=
e</i>.,
<i style=3D'mso-bidi-font-style:normal'>Technical Issues</i> or <i
style=3D'mso-bidi-font-style:normal'>Excel Support</i>. In this new organiz=
ation,
if the professor realizes that it is necessary to inform the entire classro=
om
of an issue, he will use the main discussion group (a one-way discussion gr=
oup
where only the professor can post messages &#8211; student's messages are
automatically discarded). This relies on the idea that community enhances
students&#8217; experiences and learning. In addition, we believe that a
smaller student group and the participation of power users will provide a
fertile environment for emerging communities. </p>

<h2>5.1. Various Recommendations</h2>

<p class=3DMsoNormal><i style=3D'mso-bidi-font-style:normal'><span
style=3D'font-size:14.0pt'>5.1.1. Ice-Breaker mandatory<o:p></o:p></span></=
i></p>

<p class=3DMsoNormal>We suggest including a simple ice-breaker where studen=
ts can
introduce themselves: Major/Birthplace/Hobbies. Obviously, this short messa=
ge
has to be restricted to the group place.</p>

<p class=3DMsoNormal><i style=3D'mso-bidi-font-style:normal'><span
style=3D'font-size:14.0pt'>5.1.2. Explicit title<o:p></o:p></span></i></p>

<p class=3DMsoNormal>The postings from the students on the discussion groups
should be very explicit. In fact, we cannot force it, but, we might propose
that discussions without a clear title should not expect an answer. Explicit
titles would be presented at the beginning of the semester including [EXCEL]
for an Excel related question or [TECH] for a Tech related question. Assign=
ments
should also be titled properly such as [ASSIGNMENT].</p>

<p class=3DMsoNormal><i style=3D'mso-bidi-font-style:normal'><span
style=3D'font-size:14.0pt'>5.1.3. Contextual help files<o:p></o:p></span></=
i></p>

<p class=3DMsoNormal>The professor suggested that we should create a
&quot;hyperlinked&quot; Web page that would send the user directly to the
associated &#8220;help files.&#8221; This technological enhancement provide=
d to
the user must have with it restrictions on redundant postings, perhaps by
taking points off grades for infractions. For instance, if a student asks a
question on the discussion group that has already been asked in the past he
loses points. Students will then think twice before carelessly questioning
their peers. The help files should also be developed using drop-down menus =
and
presented separating the content: Excel help, MIS help, etc. The help files
should be numbered. In fact, we want power students to refer to these files=
 by
number (after a question from the student, the Power User might propose to =
look
at help file # 24). The help files will be designed using the most frequent=
ly
asked questions from previous semesters. A voting system will have to be
implemented at the end of the help file to find out if the help file helped=
 the
student or not. The top three could be posted in the Home Page or in the Ma=
in
discussion group.</p>

<h1>6. CONCLUSION</h1>

<p class=3DMsoNormal>The entire E-learning or DE project placed the student=
 in
the middle of the learning experience, and aimed to <i style=3D'mso-bidi-fo=
nt-style:
normal'>horizontalize</i> knowledge transfer (student-to-student rather than
professor-to-student), involving the student in his learning experience. Ye=
t,
results are not satisfying and students are progressively loosing confidenc=
e in
this pedagogical concept. After observing and interviewing students from an
online web-based course we realized the importance of caring learning
communities in knowledge creation. We recommend segmenting students accordi=
ng
to their level and give various guidelines to correctly administer large on=
line
classrooms.</p>

feature of many postsecondary education institutions and&#8230;it will beco=
me
only more common in the future&#8221; [3]. In the wave of migration to new
instructional delivery modes, it is necessary for us to critically examine =
some
issues that have arisen, in order to reach an optimal solution for both the
students and the instructors. One of the inevitable tradeoffs in an online
learning environment is a decrease in the quality of social interaction. So=
cial
interaction is innate in traditional face-to-face classrooms. It is not onl=
y a
critical element in helping the learners to develop a sense of belongingness
within a learning community, but also determines the dynamics of the learni=
ng
community, which greatly influence the students&#8217; learning outcomes. <=
/span>Among
the essential components of a community, interaction between the members is
deemed to be the one crucial factor that makes a community alive. Researche=
rs
agree <span class=3DStyleReferencesLeft0Firstline0Char>that helping students
develop a sense of </span>community<span
class=3DStyleReferencesLeft0Firstline0Char> is an important aspect in promo=
ting
positive learning experiences and better learning outcomes in distance lear=
ning
environments [7]. <o:p></o:p></span></p>

<p class=3DMsoNormal>The decreased quality of social interaction in online
learning environments is usually attributed to the decreased degree of soci=
al
presence. Social presence is defined as &#8220;the degree of awareness of
another person in an interaction and the consequent appreciation of an
interpersonal relationship&#8221; [9]. Short, Williams, and Christie argued
that social presence is essential in person-to-person communication [6]. As=
 the
degree of social presence declines, the communication is perceived as more
impersonal. According to Argyle and Dean [1] and Wiener and Mehrabian [11],=
 the
two components of social presence are intimacy and immediacy. Intimacy refe=
rs
to physical proximity, visual cues (such as eye contact, body language), and
topic of communication. Immediacy regards the psychological distance that is
set by the signaler to the receiver in an event of communication. Immediacy
could be verbal and nonverbal, such as physical proximity, facial expressio=
ns,
formality of dress, or body language. </p>

<p class=3DMsoNormal>A factor that contributes to determining the degree of
intimacy and immediacy is information richness. Daft and Lengel [2] describ=
ed
information richness as the capability of information to alter or clarify
understanding within a given timeframe. Information richness is usually use=
d to
classify media&#8217;s capacity to deliver intimacy and immediacy. In terms=
 of
degree of information richness, face-to-face is the richest medium for
communication, and impersonal written documents contain low degrees of
information richness [10]. Face-to-face communication affords the richest
information for the receiver to determine the degree of social presence. The
reason for that is not only because of the face-to-face medium&#8217;s
capability to provide immediate feedback or the visual cues that the signal=
er
exhibits, but also because of the ambient cues from the environment. That t=
he
two physical and psychological measures - intimacy and immediacy - share a
common indicator of physical proximity also provides a theoretical explanat=
ion
for the high degree of social presence in face-to-face communication.</p>

<p class=3DMsoNormal>Present formats of classrooms can be roughly divided i=
nto
two main categories: traditional face-to-face settings and online courses. =
In
the order of degree of information richness, online courses can be further
classified as (1) with videoconferencing capability, (2) with audioconferen=
cing
capability, (3) with synchronous chat room capability, (4) with asynchronous
discussion board capability, and (5) instruction and content display only.
Whiteman [10] suggested that information-rich media facilitates communicati=
on
by increasing opportunities for overcoming different frames of reference
possessed by the members of the communication event. Also, the higher capac=
ity
for processing and decoding complex, subjective messages in information-rich
media helps an individual more easily interpret the psychological aspect of=
 the
message. Therefore, the face-to-face classroom setting is the most ideal me=
dia
for affording optimal social presence because of its capability of providing
full-scale intimacy and immediacy. Online classroom settings could provide
various degrees of social presence depending upon their capability for
information richness. </p>

<p class=3DMsoNormal>As mentioned earlier, social presence is a critical fa=
ctor
that affects the quality of social interaction within a group, and conseque=
ntly
influences the dynamics of the group. Creating a learning environment with a
high level of social presence not only benefits the learners&#8217; need fo=
r social
interaction, but also provides opportunities for collaborative learning.
Collaborative learning enhances learning by providing the learners with
multiple perspectives on the issues under study from each of the members in=
 the
learning community and promotes active engagement in the learning processes
[5]. Moreover, collaboration is a core component in the establishment of a
learning community. The learners&#8217; development of a sense of learning
community will be greatly influenced by their perception of the social pres=
ence
of other members. </p>

<p class=3DMsoNormal>With respect to the low social presence of online lear=
ning
environments, there is a call for an effort to create a &#8220;human touch =
of
attentiveness to their students&#8221; in distance learning [8], and facili=
tate
online learning experiences that more closely resemble traditionally accept=
ed
practices [4] when implementing online courses. The low social presence in
online learning environments creates an invisible obstacle that hinders the
development of a sense of a learning community among the online learners an=
d,
in turn, sometimes decreases the learners&#8217; desire to take online cour=
ses
or undermines their learning outcomes. Thus, the question of how to increase
the two major components of social presence: intimacy and immediacy, is an
important issue in distance education research [9].</p>

<h1>2. THE CASE</h1>

<p class=3DMsoNormal>The <st1:PlaceType w:st=3D"on">University</st1:PlaceTy=
pe> of <st1:PlaceName
w:st=3D"on">Arizona South</st1:PlaceName> is a branch campus of the <st1:Pl=
aceType
w:st=3D"on">University</st1:PlaceType> of <st1:PlaceName w:st=3D"on">Arizon=
a</st1:PlaceName>,
located in <st1:City w:st=3D"on">Sierra Vista</st1:City>, southeast of <st1=
:place
w:st=3D"on"><st1:City w:st=3D"on">Tucson</st1:City></st1:place>. In respons=
e to the
demand of serving a large population of students from rural areas, and the
difficulty students have in traveling long distances to attend classes, the
university implements a &#8220;small scale multiple satellite campuses
model.&#8221; This model turns traditional schooling around so that instead=
 of
the students traveling from all over southeastern <st1:State w:st=3D"on">Ar=
izona</st1:State>
to the headquarter campus, the same courses are offered in multiple locatio=
ns
throughout southeastern <st1:place w:st=3D"on"><st1:State w:st=3D"on">Arizo=
na</st1:State></st1:place>.
The students can choose to attend the classes held on a campus that is clos=
e to
their homes or workplaces. This model capitalizes on the students&#8217;
willingness to take classes from the university, and therefore, promotes
enrollment. However, this model is a double-edged sword: offering multiple
sections of a course in multiple locations can reach and serve a larger stu=
dent
population (particularly in rural areas), yet, at the same time, this pract=
ice
increases the number of instructors needed to teach at the different locati=
ons,
which increases the financial burden of the university with costs such as
salaries and travel funds. </p>

<p class=3DMsoNormal>In order to solve this dilemma and still keep our prom=
ise to
provide equal quality education opportunities to our students, we have
developed a blended instructional delivery method to satisfy the
students&#8217; needs and to balance the cost of offering courses at multip=
le
locations. The blended instructional delivery method we use is a combinatio=
n of
in-class and virtual class meetings. Instead of employing multiple instruct=
ors
or an instructor who teaches at different locations at different times for =
one
course, the course is taught by one instructor with multiple sections. The
multiple sections of this course take place at the same time but at differe=
nt
locations. The instructor is on one campus leading class sessions with stud=
ents
in a computer lab, other students are in a computer lab on another campus, =
and
still other students participate from their offices or homes. All students =
are
equipped with the necessary hardware and are able to run a videoconferencing
system via a high-speed Internet connection. All students may choose to
physically attend class (either on the site where the instructor is or at t=
he
site where only the students are attending), or to participate in the class
virtually from their homes or offices.</p>

<p class=3DMsoNormal>The main rationale for choosing and implementing this =
method
of instructional delivery is to optimize the students&#8217; learning outco=
mes
and experiences by finding a balance between the quality of students&#8217;
learning communities and the limitations of the university. Developing and
delivering instruction totally online is an easier solution. However, enhan=
cing
the quality of learning is more important than seeking a convenient solutio=
n.
In this case, helping students develop a sense of a learning community in
online learning environments by promoting the quality of social interaction=
 is
our focus for reaching the goal. Social presence is a critical factor in
determining the quality of social interaction. In this case, under the
practical considerations and limitations that we have, the blended instruct=
ion
delivery method provides a viable solution to solving administration proble=
ms,
and at the same time, maintains maximum quality of education for the studen=
ts.
In the order of intimacy and immediacy, the degree of social presence in th=
ese
three types of classroom settings in the blended instruction delivery method
is: (1) the classroom with the presence of the instructor and the students,=
 (2)
the classroom with the students only, and (3) virtually participating in cl=
ass.
The first setting, without doubt, provides the maximum quality of social
interaction. The second setting is a compromised solution that provides less
than perfect quality of social interaction for the students. The third sett=
ing,
participating in classes virtually from home or the workplace, provides the
students who are not able to physically attend any of the classrooms due to
geographical or time restraints with the opportunity to take the class. <sp=
an
style=3D'mso-spacerun:yes'>&nbsp;</span></p>

<p class=3DMsoNormal>The two physical class meeting sites are two computer =
labs
on two campuses. In these two computer labs, each workstation is equipped w=
ith
BITS synchronous online collaboration software, a set of headsets with a
microphone, a webcam, and a T1 connection. The BITS collaboration system has
the functions of text-based chat, videoconferencing, application sharing, a=
nd
messenger. The students who choose to participate in the virtual class meet=
ing
have to install the BITS system and the necessary hardware themselves. The =
BITS
system requires a broadband Internet connection due to the high bandwidth
demand for conducting a videoconference during the class sessions. Because =
this
blended instructional delivery method was implemented in our program for the
first time this year, we were interested in what impact the technology impo=
ses
on the students&#8217; learning in terms of building a learning community as
well as individual learning. We were particularly interested in how this
blended learning environment (face-to-face plus semi-face-to-face plus tota=
lly
virtual,) affects (1) their interest and motivation to learn and participat=
e in
the class, and their perception of the interaction with the instructor and
other students (physically present or virtually present), (2) the degree to
which social presence affects students&#8217; interest and learning outcome=
s,
given that students choose whether or not to participate virtually.</p>

<p class=3DMsoNormal>Based on informal observations of the students&#8217;
attendance and interactions both online and in the classroom throughout a
semester, and interviews with the students, we found the blended instruction
delivery method to be an effective means for enhancing social interaction a=
mong
students. The following describes what we learned from the implementation of
this class.</p>

<p class=3DMsoNormal>Our observations confirmed that the degree of social
presence is a critical factor for increasing the quality of social interact=
ion.
Given the choice of participating in the classes by having to come to the
meeting sites or by meeting with the class virtually from home or a workpla=
ce,
a majority of the students chose to come to the meeting sites, either with =
or
without the instructor&#8217;s presence. This indicated that intimacy and
immediacy do play an important role in formulating a more accepted mode of
social interaction. Videoconferences could provide the learners with more
face-to-face intimacy and immediacy, however, the lack of ambient environme=
ntal
information in the videoconferencing environment degrades the learners&#821=
7;
(both signalers and receivers) perceptions of social presence due to its li=
mited
affordability of information richness. In the need to seek psychological and
social support from the learning community, the students felt that forming a
real-life learning community was more important than their own convenience.=
</p>

<p class=3DMsoNormal>One tradeoff of the blended instruction delivery metho=
d was
that the degree of social interaction in the classroom decreased compared to
face-to-face classroom instructional delivery due to the physical setting of
computer labs and the format of interaction. Even though the students were
present in the same physical location with or without the presence of the
instructor, the class sessions proceeded in a form of terminal-to-terminal
communication, rather than face-to-face. This could have resulted from two
factors: the setting of the computer lab or the students&#8217; adaptation =
to
this new instructional delivery method. The physical arrangement of the labs
had the computer terminals arranged in straight rows with the monitors on t=
op
of the desks. Furthermore, because this blended instructional delivery meth=
od
was implemented in our program for the first time, both students and the
instructor were probably still habituated to the typical online class mode.=
 The
main classroom interaction among the students and the instructor leaned more
toward a typical online classroom; that is, communicating through computers
instead of face-to-face (even when they were physically present in the same
location). Yet, some face-to-face interaction was observed. For example, the
students would seek clarification about unclear points or concepts directly
(face-to-face communication) from their fellow students who were in the same
computer lab. This type of communication was seen less between the students=
 and
the instructor. There might have been a psychological barrier that the stud=
ents
(and perhaps the instructor as well) unconsciously imposed upon themselves.=
 The
students and the instructor might have failed to seek alternatives and limi=
ted
themselves to thinking that because the class session was proceeding on the
computer and everyone was sitting in front of a computer, all communication
should be via the computer interface. As a result, they may have overlooked=
 the
higher degree of social presence that was available to them and did not take
advantage of it.</p>

<p class=3DMsoNormal>One of the advantages of the blended instructional del=
ivery
method over a complete online delivery method is the minimum number of
technical skills required of the students. The physical meeting sites elimi=
nate
the demands on students who are unable to deal with technical issues, such =
as
installing necessary software, setting up headsets and cameras, calibrating
audio and video settings in the program, as well as unexpected technical
problems. An online course that utilizes audio/videoconferencing meeting mo=
des requires
that learners possess a certain degree of technical knowledge and an abilit=
y to
troubleshoot. The fact is that not every student is technologically capable.
Most importantly, the focus of the class should be on learning the subject
matter, rather than on training the learners how to use the technology.
Therefore, the technology should be transparent enough so that the learners=
 can
devote all their energy to learning the subject. The blended instructional
delivery method provides the students with facilities equipped with
ready-to-use technology and on site technical support staff. This way, the
students do not have to deal with the hardware and software issues, and are
able to concentrate on their learning. </p>

<p class=3DMsoNormal>An observation we had throughout the semester was that=
 the
students turned off the video windows after only a few weeks of the class. =
One
interpretation for this phenomenon is the immaturity of the technology, whi=
ch
hindered the communication, and as a result, undermined the students&#8217;=
 desire
for obtaining higher degrees of social presence. Even though each
student&#8217;s Internet connection was at the speed of a T1 or DSL, the
transmission of video was not smooth and sometimes slowed down the interact=
ions
in other modes of communication, such as audio or application sharing. The
capability of technology noticeably decreased the students&#8217; willingne=
ss
to use the video function during the class. Until this problem can be solve=
d,
synchronous online classes will still remain primarily based on text and au=
dio
communication. In terms of providing high degrees of social presence in onl=
ine
learning environments, there is still a great deal of room for improvement.=
 </p>

<p class=3DMsoNormal>The blended instructional delivery method appears to b=
e a
promising method that will provide students with an optimal learning
environment under constraints that many institutions and students are facin=
g.
Building a learning community is not only important in traditional face-to-=
face
classroom settings, but also crucial for online learning environments since=
 the
social presence is inherently low in these settings. The blended instruction
delivery method is a method that takes the advantage of both face-to-face a=
nd
online classroom settings, and provides a viable solution to various dilemm=
as.
The intention we had in utilizing the blended instructional delivery method=
 was
to seek the best possible medium for students&#8217; needs, as well as the
institution&#8217;s resource management needs, rather than to make a claim =
for
the superiority of blended instruction. This report is the result of a
preliminary observation of the implementation of a blended instructional
delivery method in graduate courses. More research is needed to systematica=
lly
evaluate the method and provide more insights for educators.</p>

<h1>1. Introduction</h1>

<p class=3DMsoNormal>This paper i<span style=3D'mso-bidi-font-size:10.0pt'>=
ntroduces
the Hook-ups initiative. In this initiative, young people learn by designing
and constructing &#8220;Hook-ups&#8221; - physical objects that can control
games, animations, and other computer programs which they create. Hook-ups =
can
be inspired by traditional computer interfaces (e.g., joysticks) or are
entirely new types of interfaces (e.g., a spaceship steering wheel). In
creating Hook-ups, young people work with objects and materials that they h=
ave
a strong interest in exploring. </span>Youth become designers capable of
integrating virtual media with materials from the world around them. By
engaging in Hook-ups design processes, learners gain confidence and motivat=
ion
to explore topics within areas such as interface design, programming, and
physics.</p>

<p class=3DMsoNormal>This investigation draws primarily from research focus=
ed on
learning through design. Specifically, it addresses the integration of phys=
ical
and virtual design. There are four main ideas on which the Hook-ups initiat=
ive
is based: (1) design is a good context for learning; (2) learners become mo=
re
deeply engaged when they have personal connections to design materials; (3)
design activities should take learners&#8217; individual styles into accoun=
t;
and (4) supporting design-based learning in environments with less structure
than traditional schools is challenging yet possible. </p>

<p class=3DMsoNormal>This paper begins with the relevant theory and work th=
at
guides Hook-ups&#8217; development, followed by a description of the
project&#8217;s design, which includes details of current Hook-ups materials
and activities. Scenarios of Hook-ups being created are then offered. Diffe=
rent
approaches to introducing Hook-ups to youth are analyzed. The paper conclud=
es
by discussing the initiative&#8217;s future directions.</p>

<h1>2. THEoretical Groundings: Learning Through Design</h1>

<p class=3DMsoNormal>The constructionist theory of learning suggests that y=
oung
people learn best through the process of constructing artifacts [3].
Kafai&#8217;s Game Design Project is an example of a learning environment
guided by this idea [2]. Kafai created an environment where fourth-grade
students created video games to help younger children learn about fractions.
Her game design tasks ranged from creating game packaging to designing user
interfaces [2]. The Hook-ups initiative extends Kafai&#8217;s work into the
domain of input device design. Additionally, the Hook-ups initiative focuse=
s,
beyond game design, on other contexts such as interactive art.</p>

<p class=3DMsoNormal>Unlike Kafai&#8217;s Game Design Project, Hook-ups
activities do not start from a pre-defined subject matter. Hook-ups project
subject matter is typically the result of free exploration. For instance, a
learner can start a project by modeling the physical behavior of a familiar
item in a simulation or game - buttons on a toy steering wheel can be conne=
cted
to a computer to control virtual racecar programs, for example. As learners
progress through their projects, they explore concepts in physics, electron=
ics,
and programming in order to realize their interface design ideas.</p>

<h2>2.1. Integrating Physical and Digital</h2>

<p class=3DMsoNormal><span style=3D'mso-bidi-font-size:10.0pt'>Recent resea=
rch
initiatives have provided preliminary indications that integrating both
physical and computational design can offer engaging educational experience=
s to
diverse sets of learners [1; 4]. </span>Programmable Bricks, an initiative
started at the MIT Media Lab, adds computation to physical objects that many
people are familiar with: LEGO bricks. Programmable brick researchers belie=
ve
that young people learn powerful ideas through participating in engaging de=
sign
experiences both on and off the computer. Commercialized versions of
programmable bricks are pocket-sized LEGO bricks (with tiny computers embed=
ded)
called &#8220;Mindstorms.&#8221; To operate Mindstorms, users create progra=
ms
and transfer them to a brick. An example program could activate motors to d=
rive
the wheels of a miniature car. The program could also read sensors to see if

<h1>3. DESIGNING HOOK-UPS</h1>

<p class=3DMsoNormal>Hook-ups are user-created devices that influence the
behavior of computer programs. They have one or more sensors that collect
information from the world and send it to computer programs (that present t=
he
data to users as numbers). For example, a light sensor can continuously rep=
ort
the amount of light in a room. The user can write a program that adjusts the
brightness of a digital image in response to the data received. Sensor inpu=
t is
captured via a Hook-ups interface board (HUB). This board connects sensors =
to
computers through the kind of wire one can find on discarded headphones.
Hook-ups can be designed for a multitude of interface boards and software
packages. The Hook-ups described in this paper interface with a graphics-ba=
sed
programming environment called Scratch [5] that already supports an early
version of the HUB.</p>

<p class=3DMsoNormal>The primary creators of Hook-ups are 10--18 year old m=
embers
of community technology centers (CTCs). <span style=3D'mso-bidi-font-size:1=

<p class=3DMsoNormal><span style=3D'mso-bidi-font-size:10.0pt'>Hook-ups act=
ivities
at CTCs can be introduced in several ways in order to provide research
opportunities for comparison and contrast between various approaches. Hook-=

young people. The second approach includes working with larger groups in
semi-structured workshops. Youth choose to work alone, in pairs, or in grou=
ps,
and the effects of the design processes for each case can be analyzed. The =
next
section highlights multiple approaches to introducing Hook-ups.<o:p></o:p><=
/span></p>

<h2>4.1. The Need for Flexibility in Introducing Design Activities</h2>

<p class=3DMsoNormal>Hook-ups activities are designed for informal learning=
 environments
that depend on the voluntary participation of youth. In such circumstances,
incorporating their pre-existing interests and activities is especially
important. The following passage, taken from my field notes, provides an
example of a flexible approach to introducing Hook-ups that resulted in a
learner using design tools and materials in new ways.</p>

<p class=3DQuote style=3D'margin-right:.5in'>I started Scratch on my laptop=
 to
gauge if onlookers would become interested in using it. I showed a sequence=
 of
sample projects - some with Hook-ups - to the members who asked me what I w=
as
doing. A fellow mentor/researcher then sat with a group of 3 members that o=
pted
to learn Scratch programming. I took approximately 8 other members interest=
ed
in Hook-ups to a table that contained items I brought such as wire, scissor=
s,
and push-buttons. The youth then added to the table materials they found su=
ch
as water bottles, plastic bags and paper plates. After 20 minutes of group
tinkering, a latecomer approached the table with a unique idea. He<span
style=3D'mso-fareast-font-family:"MS Mincho"'> grabbed two wires and reques=
ted
the scissors. He did not cut the wires; instead he taped a wire to each han=
dle.
He explained that when a person was cutting, the wires would meet and trigg=
er
an explosion [on the screen]. Another member used Scratch&#8217;s image edi=
tor
to draw graphics depicting explosions. The visit concluded by my building an
example program that tied together the scissor interface and the explosion
animation.</span></p>

<p class=3DMsoNormal>The Hook-ups initiative will also explore the balance
between structure and flexibility in informal learning environments. As sho=
wn
in the passage above, human support, basic materials, and project examples =
are
provided. Project examples are carefully selected based on their ability to
demonstrate how multiple simple elements come together to make engaging pro=
jects.
Participants have the flexibility to use elements of provided materials in
conjunction with elements they bring to the activities.</p>

<p class=3DMsoNormal>Simple Scratch program examples can quickly be deconst=
ructed
and rebuilt to show how basic programming concepts work. Some learners are =
able
to see an example rebuilt and begin manipulating programs right away. For
others, designing a physical interface to a program makes the programming t=
ask
more approachable. For example, the following passage presents such an inst=
ance
of a learner overcoming a perceived inability to program. As a result of
becoming deeply involved in the construction of a tangible interface, the
learner found the motivation to become involved in the programming of a Scr=
atch
project.</p>

<p class=3DMsoNormal>Six 12-year-old participants attended a 2-day mini-vid=
eo
game design workshop. They decided to collaboratively create a game about
violence and television. Each participant volunteered to lead one aspect of=
 the
game&#8217;s design. No one volunteered to build the Scratch program to
integrate all of the parts (hesitation is understandable given the complexi=
ty
of the task and the limited amount of time available). The workshop leaders
gave the group an introduction to Scratch programming yet some members did =
not
catch on. One member named Jack was unable to understand the basic programm=
ing
concepts and began to lose interest. Jack was presented with a box full of
scissors, tape, wire, and old toys and asked if he was interested in creati=
ng a
controller for the group&#8217;s game. With a small amount of adult assista=
nce,
Jack created a one-button remote control to flip past violent channels on a
virtual TV. With a desire to program something that would respond to his re=
mote
control, Jack became motivated to program. He retained and reused concepts =
in
conditional programming to achieve his task. He even faced the challenge of
programming the TV to loop back to channel 1 after reaching the highest
channel.</p>

<h1>5. future DIRECTIONS</h1>

<p class=3DMsoNormal>The Hook-ups initiative is in its very early stages. F=
uture
Hook-ups research will establish <span style=3D'mso-bidi-font-size:10.0pt'>=
new
activities that integrate multiple types of design. By doing so, a better
understanding will be gained of how young people learn when they are engage=
d in
flexible design processes. The Hook-ups initiative will continue to investi=
gate:
</span>(1) how input device design is a good context for learning; (2) how
learners become engaged in physical and virtual design processes when
connections to different design materials are established; (3) how design
activities adapt to individuals&#8217; learning styles; and (4) how the
structure and flexibility of Hook-ups design activities contributes to youth
learning ideas from areas such as programming, interface design, and physic=
s.</p>

<h1>1. INTRODUCTION</h1>

<p class=3DMsoNormal>Applications of information technology to support syst=
emic
reform in public school systems have taken several forms. Instructional
applications include attempts to more effectively convey information to
students, to empower students' own agency in accessing information and
constructing knowledge, and to aid teachers&#8217; classroom management, le=
sson
preparation, and assessment. Technology has been proffered as a change agen=
t in
itself: teachers will need to change their practices in order to use
technologies designed for doing authentic inquiry and communicating or coll=
aborating
with others [10]. Information technology can also support professional
development through access to online courses, and enable participation in
distributed communities of practice. The work reported in this paper has ta=
ken
this latter strategy. Because today&#8217;s school systems operate in an
environment of constant change, professional development requires a paradigm
shift from a scripted training approach to a more fluid approach that
encourages the incorporation of networks, coalitions, and partnerships. The
capacity to network with other professionals is essential to the notion of
communities of practice. McLaughlin and Mitra argue that sustaining large-s=
cale
theory-based reform efforts &#8220;requires a community of practice to prov=
ide
support, deflect challenges from the broader environment, and furnish the
feedback and encouragement essential to going deeper&#8221; [7]. Barab defi=
nes
a community that advances ongoing and open-ended professional development a=
s a
&#8220;persistent, sustained network of individuals who share and develop an
overlapping knowledge base, set of beliefs, values, history and experiences
focused on a common practice and/or mutual enterprise&#8221; [1]. These
communities change the relationships among teachers, breaking the isolation=
 that
most teachers have found so confining.</p>

<p class=3DMsoNormal>Over the past several years, Hawai`i Networked Learning
Communities (HNLC), a National Science Foundation Rural Systemic Initiative
(RSI), has been supporting communities of educators in <st1:place w:st=3D"o=
n"><st1:State
 w:st=3D"on">Hawai`i</st1:State></st1:place>. The goal of HNLC is to empower
educators to prepare students in economically disadvantaged rural schools f=
or
life and careers in today&#8217;s complex and dynamic technological world by
enabling them to attain high standards in science, mathematics, and technol=
ogy
(SMT). HNLC is the result of collaboration between the Department of
Information and Computer Sciences (ICS) of the <st1:place w:st=3D"on"><st1:=
PlaceType
 w:st=3D"on">University</st1:PlaceType> of <st1:PlaceName w:st=3D"on">Hawai=
`i</st1:PlaceName></st1:place>
at Manoa (UHM) and the Advanced Technology Research Branch (ATRB) of the
Hawai`i Department of Education (HIDOE). One component of our work is a
&#8220;virtual community center,&#8221; realized as a dynamic website
(hnlc.org). We chose to use Internet technology to build and sustain a
community of rural educators because they work in small and isolated schools
separated by island geography. This website targets educators at two levels:
teams of educators who are formally involved in HNLC, and the broader commu=
nity
of educational stakeholders in <st1:place w:st=3D"on"><st1:State w:st=3D"on=
">Hawai`i</st1:State></st1:place>.
The website includes a community forum for sharing news and stories of any
nature deemed appropriate by members, and a database of Hawai`i-based resou=
rces
for education. Two additional tools are specifically intended to support the
work of HNLC school teams: a template that guides unit planning, and an
&#8220;artifact-centered&#8221; discussion tool for sharing and discussing
work.</p>

<p class=3DMsoNormal>In the spring and early summer of 2003 (about 12 months
after hnlc.org was first released), we undertook our first evaluation
specifically targeted at determining levels of teacher use of our online
community tools. This evaluation is summarized in Suthers, et al. [13]. At =
the
time of the evaluation, our work was focused on getting small teams of teac=
hers
to collaborate, online as well as face-to-face, in order to plan
standards-based, assessment-driven and student-centered inquiry units. Over=
all,
respondents had positive attitudes about the use of technology in general f=
or a
range of purposes, but as of summer 2003 they had not made significant use =
of
hnlc.org outside of sponsored events, with the exceptions of school teams
preparing for those events and the initiative of a few individuals. Focus
groups indicated some differences in the expectations of developers and use=
rs.
The results of this study challenged us to rethink our efforts to use Inter=
net
technology in support of systemic reform. In this paper we summarize the mo=
st
important portion of our deliberations concerning the <i style=3D'mso-bidi-=
font-style:
normal'>community</i> and <i style=3D'mso-bidi-font-style:normal'>practices=
</i>
to be supported.</p>

<h1>2. WHAT COMMUNITY SHOULD BE SUPPORTED?</h1>

<p class=3DMsoNormal>Although our ultimate goal is increased <i style=3D'ms=
o-bidi-font-style:
normal'>student</i> performance and participation in SMT, we want to accomp=
lish
this in a sustainable manner, which requires that we change the practices of
those directly responsible for student learning rather than working directly
with students ourselves. Therefore we reaffirmed that we want to support the
work of teachers. Our working assumption from the outset has been that if
teachers experienced the use of technology in their learning they would bet=
ter
understand how to use it for their students&#8217; learning. However, as
discussed below, we found that we cannot neglect designing technology for u=
se
by students.</p>

<p class=3DMsoNormal>HNLC has been working with school teams formed for the
purpose of representing each school to HNLC and developing an integrated un=
it
plan as a model of how education could be done in their school. These teams=
 may
or may not be constituted of prior collaborators. An alternative approach i=
s to
identify existing communities within the schools rather than leaving team
formation up to school administrators [6]. Regardless of how they are forme=
d,
school teams should enable educators of different disciplines or at differe=
nt
grade levels within a school to work with each other towards continuity in =
the
students&#8217; learning experience across classes and grade levels.</p>

<p class=3DMsoNormal>We also recognize that relevant communities can extend
beyond the schools. Teachers specializing in a given subject or grade level=
 may
want to network with each other across schools, forming <i style=3D'mso-bid=
i-font-style:
normal'>communities of practice, </i>the second &#8220;knit&#8221; of a
double-knit organization [14]. They may wish to discuss specific math and
science projects being implemented on multiple campuses as well as applicat=
ions
for curriculum resources being used in various classrooms. There are also
groups defined by administrative structures such as the HIDOE complexes (hi=
gh
schools and their primary and intermediate feeder schools). Collaboration
within a complex could improve the educational experience from the
students&#8217; point of view if innovations at the primary and secondary
levels were coordinated. Finally, we considered whether our HNLC colleagues
within the HIDOE should be the primary targets of our technology support. T=
he
ATRB team members plan the HNLC professional development program and carry =
it
out in scheduled events, school visits, and online instruction. Although AT=
RB
staff suggested that we focus on teachers, we recognize the need to work
closely with the ATRB staff to ensure that the affordances of our technolog=
ies
mesh well with their plans for professional development. For example, we fo=
und
that because participants will most likely try new tools and practices at
face-to-face training sessions organized by ATRB, we need to design for
transitions between face-to-face and online use.</p>

v:shapes=3D"_x0000_s1061"><![endif]><span style=3D'mso-no-proof:yes'>Our ef=
forts
would be diluted if we tried to support all of these communities at once, b=
ut
nor can we focus only on school teams and ignore their context. We now beli=
eve</span>
that hnlc.org must selectively support <i style=3D'mso-bidi-font-style:norm=
al'>nested</i>
and <i style=3D'mso-bidi-font-style:normal'>overlapping</i> communities of
practice [9; 14] that extend beyond the schools and into the general commun=
ity.
We need to focus on teachers as those primarily responsible for student
achievement, but not neglect the larger community context of education. Our
primary focus in the design of hnlc.org is now on both the school teams and=
 on
inter-school collaborations (communities of practice) in which educators and
ATRB staff share ideas and advice (Figure 1). Our secondary focus remains on
the larger community that forms the environment of resources and expectatio=
ns
within which our primary communities grow. Our working hypothesis is that i=
t is
<i style=3D'mso-bidi-font-style:normal'>essential</i> for the sustainabilit=
y of
systemic reform that we not only address the needs of the practitioners who=
se
work immediately impacts upon student performance, but also initiate change=
 in
the broader community that places expectations on the school system as well=
 as
provides the resources to meet those expectations.</p>

<p class=3DMsoNormal>Discussions in the Community-Based Learning Workshop h=
eld at
the 2004 International Conference on the Learning Sciences reinforced our v=
iew
of the importance of nested communities and provided us with some fresh ide=
as
about how we can support these communities. One way is through fostering a
common identity and a culture of shared meaning and practices. A recent
redesign of hnlc.org recognizes the importance of community awareness. Pers=
onal
profiles displaying each member&#8217;s community contributions serve to bu=
ild
their reputations within the community as well as facilitate finding other
contributions by the same member [5]. Allowing the members to personalize t=
heir
online presence by sharing information about themselves creates opportuniti=
es
for finding others with similar interests or complementary skills, thus
facilitating the forming of new collaborative connections and groups [4].</=
p>

<p class=3DMsoNormal>The concept of small group cognition helps clarify our=
 focus
on teacher teams. Small groups are the unit that mediates between individual
learning and community learning, and therefore are the appropriate unit of
action for systemic reform [11]. Yet small groups do not exist in isolation:
they form out of and are supported by communities. We are initiating a new
effort to mobilize and support new members from the statewide community, wi=
th
the expectation that this effort will foster new small communities of inter=
est
and that they will leverage resources provided by the larger community. We
intend to study the interaction between the larger community, small communi=
ties
and groups, and individual teachers in our target population to determine t=
he
effect of embedding in nested communities and how this is mediated by our
technology.</p>

<h1>3. WHAT PRACTICE SHOULD BE SUPPORTED?</h1>

<p class=3DMsoNormal>Having clarified the overlapping and nested spheres of
communities of practice that we intend to support, we are still faced with =
the
question, &#8220;What practice?&#8221; Should we design our system to meet
practitioners&#8217; immediate needs and working practices (as conventional=
 wisdom
in human-computer system design suggests), even if that meant supporting the
existing teacher-centered forms of instruction?</p>

<p class=3DMsoNormal>We would be neglecting the systemic reform&#8217;s obj=
ective
of <i style=3D'mso-bidi-font-style:normal'>changing</i> practice if we mere=
ly
focused on supporting existing practice. Systemic reform requires that
something sustainable change in the <i style=3D'mso-bidi-font-style:normal'=
>system</i>
beyond an immediate impact on this year&#8217;s cohort of students.
Furthermore, systemic reform means change, and that may mean trying to get
educators to do things other than that which they think they most need. We =
need
to change their practices as well as support them. The objective of this re=
form
is a reflective-action form of practice &#8211; akin to action research &#8=
211;
in which teachers use embedded assessment to examine the effects of their i=
nstructional
interventions and the learning opportunities they create for student
performance, and adjust those interventions and seek new opportunities as
needed to improve performance. If <i style=3D'mso-bidi-font-style:normal'>t=
his</i>
were the prevalent practice of our user community, then the tools that they=
 need,
and indeed demand, would be different than at present.</p>

<p class=3DMsoNormal>What role does technology play in driving the change
process? Can we offer technology (integrated with professional development)
that meets the demands of this imagined community of practice of the future,
and thereby perturb the present activity system to change towards that futu=
re?
This strategy will not work if educators don&#8217;t use the tools, and they
won&#8217;t use tools that don&#8217;t meet their present needs. Also, this
approach presents a triple challenge: by asking teachers to (1) work
collaboratively, (2) via online technology, and (3) to plan and engage in
student-centered inquiry learning, we are asking them to do three things th=
at
most of them are not accustomed to doing. If teachers have not engaged in
reflective discussion even in face-to-face settings, it is unrealistic to
expect this behavior in an online environment [6]. Where do we begin?</p>

<p class=3DMsoNormal>Our hope is that the distinction between supporting and
changing practice may be artificial or irrelevant, if the tools we offer are
amenable to supporting both practices in teachers&#8217; current zone of
proximal development as well as more reflective practices of the future.
Strategically, we need to build tools to support current practice, gain acc=
eptance,
and then build on this base to change the practice along with and through t=
he
tools. This process could be supported by technology serving as a collabora=
tive
workspace with functions to enable socialization and interpersonal connecti=
on
[2].</p>

<p class=3DMsoNormal>A related question is how teachers will learn to use
technology. We began under the assumption that educators could learn to tea=
ch
with technology by first learning to learn with technology. However, through
surveys and focus groups as well as informal experience we found that HNLC
educators tend to view technology as resources for use with their students,=
 and
are more likely to be inspired by their students&#8217; use of technology t=
han
vice-versa. Yet they also acknowledge that technology is an important resou=
rce
for their own professional development. Perhaps the resolution to this appa=
rent
tension between teacher-first versus student-first use is to shape professi=
onal
development so that participants use the tools in the way students would be
asked to use them in inquiry-based learning. They would thereby gain
simultaneous training in the practice of inquiry-based learning and the use=
 of
technologies as specifically applied to the inquiry activities of themselve=
s <i
style=3D'mso-bidi-font-style:normal'>and</i> their students.<i style=3D'mso=
-bidi-font-style:
normal'><o:p></o:p></i></p>

<h1>4. WHAT DO WE BUILD?</h1>

<p class=3DMsoNormal>We have so far considered what we can do to support pr=
esent
and future practices of multiple communities and teams. A deeper problem ar=
ises
if many of these communities of practice do not already exist. Then the
question becomes, &#8220;What do we build &#8211; the community, the practi=
ce,
or the tools?&#8221; Communities of practice need to be built from a complex
array of factors and in a manner that is timely and unique to each group. A
community design cannot simply be proffered to a group [3]. Kling and
Courtright contend that it is easier to foster technology <i style=3D'mso-b=
idi-font-style:
normal'>supported</i> community development than to nurture technology <i
style=3D'mso-bidi-font-style:normal'>initiated</i> communities [6]. Communi=
ties
evolve within groups around their particular needs and for purposes that th=
ey
value. Program planners must face issues of sociability as well as usabilit=
y in
developing a design that links to and supports people&#8217;s social
interactions [2; 8]. Fostering trusting and respectful relationships is
paramount. This is the basis for community building, and, once established,
each community of practice then directs the development, adoption, and use =
of
technology for its specific needs. The process combines both bottom-up and
top-down efforts to answer the questions we pose here. When multiple, nested
communities of practice are involved, our responsibilities for attentiveness
and technological responsiveness are correspondingly increased and should be
clearly prioritized.</p>

<h1>5. CURRENT RESEARCH</h1>

<p class=3DMsoNormal>Our continued research is organized around two major i=
ssues:
(1) technology-supported communities and systemic reform (as discussed abov=
e),
and (2) the affordances of technology as a mediating artifact in supporting
these communities [13]. We raise the following questions to guide our
investigation. (1) What strategies can encourage time-pressed,
technology-hesitant teachers to use technology for their own learning and
collaboration? Once technology has been adopted for collaboration, how do t=
he
new relationships and communities so formed influence classroom practices
towards genuine inquiry? How are new relationships formed via technology or=
 via
a mixture of face-to-face and online interactions? Does the embedding of sm=
all
groups within the context of a statewide online community lead to the forma=
tion
and enhancement of small group work? Do technology-mediated groups or
communities change the operation of the organization in which they are
embedded? (2) How is technology used not only as &#8220;communication
channel&#8221; but also as a medium within which questions and problems are
identified and shared solutions are negotiated? How can design of
representational notations influence such collaborative inquiry? How can
workspaces be adapted to users' needs?</p>

There are many other seminal voices concerning distributed cognition from
fields such as phenomenology (e.g., Merleau-Ponty [23]), cognitive science
(e.g., Hutchins [17]), and educational psychology (e.g., Salomon [28]),
including enactivism (e.g., Davis &amp; Sumara [6]). It is well beyond the
scope of this paper to discuss the implications of these diverse approaches=
. </p>
