knowledge-creation model. Distinctions were set up between three modes of discourse:
knowledge sharing, knowledge construction, and knowledge creation. These were applied to
the asynchronous online discourses of four groups of secondary school students (40 students
in total) who studied aspects of an outbreak of Severe Acute Respiratory Syndrome (SARS)
and related topics. The participants completed a pretest of relevant knowledge and a
collaborative summary note in Knowledge Forum, in which they self-assessed their collective
knowledge advances. A coding scheme was then developed and applied to the group
discourses to obtain a possible explanation of the between-group differences in the
performance of the summary notes and examine the discourses as examples of the three
modes. The findings indicate that the group with the best summary note was involved in a
threshold knowledge-creation discourse. Of the other groups, one engaged in a knowledge-
sharing discourse and the discourses of other two groups were hybrids of all three modes.
Several strategies for cultivating knowledge-creation discourse are proposed.

Introduction
For two decades, Carl Bereiter and Marlene Scardamalia have been developing an educational
model intended to make the processes experts use to advance the state of knowledge in their fields
more common in education. The model was initially called
intentional learning
suggesting that knowledge is the product of
a constructive process (Bereiter and Scardamalia 1993 ). But as constructivism has gained wide

Abstract The study reported here sought to obtain the clear articulation of asynchronous
computer-mediated discourse needed for Carl Bereiter and Marlene Scardamalia
to emphasize
that learning needs to be an intended goal rather than the by-product of activities (Bereiter and
Scardamalia 1989 )andthen

acceptance in education, it has become difficult to distinguish knowledge building from
constructivist learning, and Bereiter and Scardamalia have begun to favor the term
knowledge
which is well established in the literature on innovation (Gundling 2000 ; Nonaka and
Takeuchi 1995 ). 1 The term refers to a set of social practices that advance the state of
knowledge within a community over time (Paavola et al. 2004 ). Knowledge creation involves
more than the creation of a new idea; it requires discourse (talk, writing, and other actions) to
determine the limits of knowledge in the community, set goals, investigate problems, promote
the impact of new ideas, and evaluate whether the state of knowledge in the community is
advancing. To support this discourse, Scardamalia and colleagues have developed a Web-based
environment, Knowledge Forum® (Scardamalia 2003 ), which includes tools for asynchronous
problem-solving interactions, idea development, synthesis, and refection.
The integration of computer-mediated asynchronous discourse into classroom practice
needs to be addressed if educational models such as knowledge creation are to be
implemented widely. My experience of working with many teachers suggests that
participant understanding of the nature of the discourse needed for knowledge creation is
crucial for such integration (van Aalst 2006 ). The goal of the study reported here was to
obtain a clearer articulation of the online discourse needed for knowledge creation.
To this end, I distinguish three modes of discourse
knowledge sharing, knowledge
construction, and knowledge creation which correspond to three established theoretical
perspectives. Knowledge sharing refers to a transmission theory of communication (see Pea
1994 ), knowledge construction to cognitive psychology (constructivism), and knowledge
creation to interactive learning mediated by shared objects (Paavola et al. 2004 ). This
division extends the cognitively oriented distinction between knowledge-telling and
knowledge-construction models of writing (Bereiter and Scardamalia 1987 ) in light of
recent theoretical developments that posit cognition as being situated in authentic situations
and practices (Brown et al. 1989 ; Hutchins 1995 ; Lave and Wenger 1991 ). The distinctions
are then applied to the analysis of a Knowledge Forum database.
The remainder of this paper is organized as follows. The next two sections describe the three
modes of discourse and their theoretical underpinnings, and provide a brief introduction to
Knowledge Forum. A case study is then presented, covering the collaboration of four large
student groups that investigated aspects of Severe Acute Respiratory Syndrome (SARS), Avian
Flu, and related topics. The case first examines evidence of collective knowledge advancement
within the groups, and then examines the nature of each group
s discourse in Knowledge Forum
using a newly developed coding scheme. The analysis of the group discourses is matched to
both the evidence of collective knowledge advancement and the three modes of discourse.
Ways to encourage knowledge-creation discourse are then discussed.
Knowledge sharing, knowledge construction, and knowledge creation
Knowledge sharing
Knowledge sharing refers to the transmission of knowledge between people. Strictly
speaking, only information can be transmitted; information is knowledge for the sender and

receiver if they comprehend its content and significance. Examples are providing factual
information to answer a query or uploading various kinds of information to an intranet. One
thing that makes such interactions effective is that the receiver has already identified a need
for the information. For example, someone new to editing digital video may need to be
shown how to add music to the video, which will address an already meaningful goal.
As a social practice, knowledge sharing is an accomplishment, especially in competitive
environments; people are not naturally inclined to share what they know unless doing so is
likely to enhance their own social position. The management literature indicates that
knowledge-sharing practices can make organizations more effective, but they need to be
cultivated (Lencioni 2002 ). In a community engaged in collaborative inquiry, knowledge-
sharing practices involve the introduction of information and ideas without paying
extensive attention to their interpretation, evaluation, and development. The perceived lack
of a need for interpretation and evaluation can be related to naïve realism, an epistemic
position according to which data speak for themselves (Science Council of Canada 1984 ).
A related epistemic belief is
quick learning,
Knowledge construction
Knowledge construction refers to the processes by which students solve problems and
construct understanding of concepts, phenomena, and situations, considered within
cognitive psychology. It is effortful, situated, and reflective, and can be individual or
social (Sullivan Palincsar 1998 ). The basic assumption of constructivism is that the student
must make ideas meaningful in relation to his or her prior knowledge and to the situation in
which the need for ideas arises (von Glasersfeld 1995 ). The cognitive processes are
qualitative changes in the complexity of students
thinking about and
(Moore 2002 , p. 27; also see Biggs
1987 ). Dole and Sinatra ( 1998 ) conceptualize the effort students invest in information
processing as
ranging from simple processing that leads to assimilation
(low), to deeper processing and some reflection that leads to knowledge restructuring
(moderate), and on to substantially metacognitive processing (high).
At moderate to high levels of engagement, knowledge construction can lead to the
substantial restructuring of knowledge, which may include the invention of new concepts
and enhanced meta-conceptual knowledge (e.g., knowledge about the hierarchical nature of
networks of concepts). For example, students may initially consider the motion of an apple
that falls from a tree to be unrelated to the motion of the earth in its orbit around the sun,
but then come to realize that both can be described using the universal law of gravitation.
This change would imply deeper insight into the nature of gravity and would lead to a
restructuring of knowledge; the resulting knowledge structure would explain a greater range
of observations and require fewer assumptions. More generally, synthesis that results in
understanding phenomena on a higher plane and the creation of new concepts is an
important form of knowledge advancement. For example, Mendeleev
engagement,
s introduction of the
periodic table of the elements accelerated progress in chemistry by predicting the existence
of unobserved elements and the creation of new concepts to explain the partially observed
patterns. Scardamalia ( 2002 ) conceptualizes such advances as
rise-above,

because they are mediated (enabled) by social interactions within the particular
group that is working together and by the particular technologies used (Brown et al. 1989 ;
Hutchins 1995 ). Knowledge construction is often associated with deep learning, which

(p. 79). Although Scardamalia proposes rise-above as a knowledge-creation
principle, I regard it as a cognitive act whereby students articulate higher levels of
understanding and not merely reorganize knowledge (Gil-Perez et al. 2002 ); nevertheless,
the need for rise-above is greater when the need for synthesis is greater.
Knowledge construction involves a range of cognitive processes, including the use of
explanation-seeking questions and problems, interpreting and evaluating new information,
sharing, critiquing, and testing ideas at different levels (e.g., conjectures versus explanations
that refer to concepts and/or causal mechanisms), and efforts to rise above current levels of
explanation, including summarization, synthesis, and the creation of new concepts.
However, educational approaches vary considerably in the extent to which they make it
possible for students to engage in these processes. Although most emphasize working with
information and ideas (e.g. Goldberg and Bendall 1995 ; Hunt and Minstrell 1996 ; Linn
et al. 2003 ), there may be limited opportunities for students to pursue problems they have
identified themselves or to synthesize ideas and formulate new concepts. For example, in
problem-based learning (Hmelo-Silver and Barrows 2008 ), students are provided problems,
although these are ill-structured and need considerable articulation. In other approaches,
students may collaborate in small groups on relatively simple tasks that require little
synthesis and reflection on progress. In the vast majority of approaches, knowledge-
construction processes are directed at acquiring the reliable knowledge of a field (Edelson
et al. 1999 ; Kolodner et al. 2003 ; Krajcik et al. 2008 ). Knowledge construction, with its
emphasis on building on students prior ideas, concepts and explanations, and their
metacognition, produces deeper knowledge in complex domains than does knowledge
sharing (Bransford et al. 1999 ; Hmelo-Silver et al. 2007 ).
Knowledge creation
is used in the literature on expertise and innovation to describe
how companies, organizations, and academic fields develop the ideas needed to sustain
innovation (e.g. Engeström 2001 ;Gundling 2000 ; Nonaka and Takeuchi 1995 ). Knowledge
creation depends on conditions in which creative work on ideas is valued and there are
mechanisms for choosing the most promising ideas for further development, and rewarding
creativity. These elements need to work together to create what Gundling ( 2000 ) has called an
knowledge creation
(p. 14).
At one level, knowledge-creation discourse involves the design and improvement of
intellectual artifacts such as theories, explanations, and proofs (Bereiter 2002 ). Drawing
from Popper
that produces
a dazzling variety of new products each year
s theory of objective knowledge, Bereiter considers ideas to be real objects
similar to bicycles or telephones. We may ask how a bicycle can be improved, and we can
ask the same of an idea. This aspect of the discourse is known as
(Bereiter
and Scardamalia 2003 ), with an emphasis on explanations, casual mechanisms, and the
coordination of claims and evidence.
However, knowledge creation is not just a rational effort. For example, the community
periodically needs discourse to identify priorities and long-term goals, decide how to
mentor newcomers, and evaluate knowledge advances. As studies of scientific practice
have shown, the associated discourse tends to be more argumentative (Feyerabend 1975 ;
Kuhn 1970 ; Lakatos 1970 ; Latour 1987 ). To mention just a few examples, in science, good

s reluctance to make public the health hazards
associated with radium, see Quinn 1995 ). In other words, belief-mode discourse also plays
an important role in knowledge creation. Despite individual idiosyncrasies, members of a
scientific field share a goal of innovation and the advancement of knowledge. Commitment
to shared goals within a team is also important in a variety of other innovative contexts
(Gundling 2000 ; Lencioni 2002 ; Nonaka and Takeuchi 1995 ).
In Bereiter and Scardamalia
s knowledge-creation model (Bereiter 2002 ; Bereiter and
Scardamalia 1996 ; Scardamalia 2002 ; Scardamalia and Bereiter 2006 ), a class of students is
considered a community that shares a commitment to creative work on ideas and advancement
of the state of knowledge in that community. Ideas are considered intellectual artifacts of the
community; they reside in the community
s minds. The
community needs to be able to identify gaps in its collective knowledge, map out ways to fill
those gaps, design and manage inquiries, manage social processes, and evaluate progress.
Thus, the community

authoritative sources (Scardamalia 2002 ) such as books, websites, and experiments, treating
them as potentially useful for informing their work. They are also expected to engage in
progressive problem solving, reinvesting cognitive resources to deepen their understanding of
problems and taking on more difficult problems over time (Bereiter and Scardamalia 1993 ).
One of the most important roles of the teacher in this process is to facilitate the development of
an innovation ecology. Important progress has been made in this direction by the development
of a system of principles that describe the socio-cognitive and socio-technological dynamics of
knowledge creation, including collective cognitive responsibility for knowledge advancement,
real ideas/authentic problems, epistemic agency, improvable ideas, rise-above, and constructive
use of authoritative sources (Scardamalia 2002 ). These principles provide a technical
vocabulary that students, teachers, and researchers can use to reflect on the extent to which
there is evidence of a knowledge-creation discourse. Initial studies show that elementary and
secondary school students are capable of engaging in the dynamics described by these
principles (Niu and van Aalst in press ; Zhang et al. 2007 , 2009 ). However, more work is
needed to characterize the innovation ecology, such as by determining the social practices that
make collaboration possible, the overall school culture, and the community s experience at
knowledge creation and its long-term goals (Bielaczyc 2006 ;Truong 2008 ). Knowledge
creation requires discourse for maintaining social relations, setting goals, deepening inquiry,
and lending support to ideas that are already understood by some in the community. For
example, van Aalst ( 2006 ) discusses how a Grade 6 student referred to the scientist Francis
Bacon to support an explanation he had proposed earlier that had not been accepted by the
community. This move was directed less at improving understanding than at improving the
impact of the student s own ideas. Similarly, students who wish to further a line of inquiry need
the ability to argue the case for doing so. These types of moves cannot be understood by
examining short-term goals such as the problem students are currently attempting to
understand, but require the consideration of higher level and longer term goals such as the
diffusion of new insight throughout the community and progressive problem solving (Hmelo-
Silver 2003 ). In groups that work together for short periods, there is less need for such moves.
There are important theoretical differences between knowledge construction and
knowledge creation, although they involve similar processes such as posing questions,
formulating conjectures and explanations, summarizing progress, and proposing rise-above
s goals are emergent. Students are expected to make
problems may not be investigated because they are not currently considered important
(Latour 1987 ). Researchers promote their own work and that of close colleagues by alerting
the community to recent findings, and may ignore important new findings that they do not
find appealing (Reeves 2008 ). Other researchers may not make their insights public, for fear
of attracting criticism (e.g., Madame Curie
