Knowledge-building community model
In the context of education, we define Knowledge-building community model as a socio-constructivist pedagogic strategy developed by what we can call the "Toronto school". It is an instructional design models that focus on a combination of situated learning, writing-to-learn, knowledge building, community, etc. It does have points in common with inquiry-based learning, i.e. the idea that learners should create knowledge through collective and collaborative inquiry. There is also a relation to transformative pedagogy and community of learning concepts.
Bereiter and Scardamalia believe a knowledge-building community should be modeled after scientific research centers, where “problem redefinition at increasingly high levels is the goal, based on a fundamentally social process. Researchers benefit from the advances of others, with continual interplay of findings, not just among scientists working concurrently but from generation to generation.”(1994). Knowledge-building communities support discourses that aim to advance the knowledge of the members collectively, while supporting individual growth with the aim of producing new experts and extending expertise within the community's domain.
A KB community can engage in collecting information, supporting discourse and exchanges, encouraging a social and professional network of learners and experts and making the knowledge acquired collectively available for future use. That even children in elementary school levels can engage in knowledge-building makes the process accessible to all levels of education.
Bereiter and Scardamalia's knowledge-building model for educational contexts suggests a way to organize instruction so that student initiated contributions to the collective knowledge and peer evaluation of knowledge produced is possible. Knowledge forum is their technological response to the needs of building a KB community through "knowledge-building discourse".
2 Knowledge-building discourse
Knowledge-building discourse has certain characteristics defined by Bereiter and Scardamalia (1994) and outlined here:
- Focused on problems, not topics: knowledge is advanced through discussion and argumentation in the effort to understand concepts and resolve discrepancies.
- Decentralized, open knowledge building, with a focus on collective knowledge: through constructive social interactions with others engaged in similar or related problems.
- More knowledgeable members are engaged in the knowledge-building process, but do not delineate the limits of investigation.
- Less knowledgeable members' participation is valued as it determines the gaps, inadequacies, difficulties in the knowledge being created that can demand a clarification of ideas by the 'experts'.
- Engages a broader knowledge community than that involved in the current local problem, bringing in views from the outside.
- Makes for a "second order environment" (one where the one's adaption to the environment changes the environment itself) where one's contributions can determine what contributions will follow, thus changing the direction of the discourse and the knowledge constructed.
These characteristics are built into the framework of CSILE designed as “an enabling technology for knowledge-building discourse.”

3 The instructional design model
The Toronto school advocates a model that differs radically from the current trend of strong scenarisation that we can find in various schools of thought in CSCL or learning design. To state it bluntly, modern learning-design and CSCL is about filling in forms and acquiring existing beliefs and such these approaches are not that different from very traditional instructional systems design.
The model is somewhat related to the inquiry-based learning. The major difference is that advanced teachers not necessarily follow a rigid inquiry circle, but rather opportunistically (in the sense of artificial intelligence planning vocabulary) guide the process. Beginning teachers however, can be encouraged to follow a more structure model. Knowledge building is not unguided ("radical constructivist") discovery learning, since the teacher does play an important role to insure that knowledge-building activities will lead to results.
4 Research approaches and tools
Recent versions of knowledge forum have built-in data-collection and analysis tools. Most Toronto school research can probably be situated in the design-based research tradition founded by Ann Brown in the early 1990s.
To measure increase in scientific thinking and knowledge gain, Jianwei Zhang et al. (2007:112) present a table of research questions and analysis that we reproduce in summarized form:
|Dynamics||Specific questions||Analyses||Expected performances|
|Idea improvement||How do questions and ideas evolve and refine over time ?||Trace the change of student's ideas.||Students shift toward a more scientific view.|
|Real ideas, authentic problems||How are real-world empirical data used ?||Use of empirical data as evidence on quality of ideas.||Students bring valuable data into the discourse and make sense of them.|
|Community knowledge||How do individual contributions spread and how are they used ?||Analyze contributions to the work of others and related knowledge gains.||Students interact in a way that supports conceptual advancement.|
|Constructive use of authoritative sources||What are the patterns of their use ?||Use of expert resources.||Students integrate expert and go beyond given information to generate and improve their ideas.|
|Overall||Overal measure of knowledge gains||Pre- and post-test comparisons; analyses of student portfolios. Correlations.||Improvement of performance pre- to post-test; Students’ portfolio notes reflect high levels of scientificness and epistemic complexity. Indicators of the dynamics correlate with quality of ideas in portfolio notes.|
- This wiki (to some extent only, i.e. DKS believes that he and some of his students learnt something about educational technology by writing and linking concepts)
- Social software websites like built with tools like ELGG (e.g.  or ) may other partial implementations of this model).
- Most "strong" examples can be found in various knowledge forum websites and that are usually not open to the public.
