2. Outline Motivation Virtuality Research Approach Knowledge & Community Learning & Community Virtual Community Issues Research Questions C-KLASS Tools & Prototype Evaluation Conclusion

3. Motivation Why do people participate in virtual communities? –to attract customers/clients –for amusement –to socialize; find comfort (medical communities) –to network, build contacts –to improve what you do (job, personal) –find information/solve problems/learn from others ==> collaboration, knowledge-sharing and learning underlies most of these directly or indirectly Research Question: How best to support this?

4. Goal Increase effectiveness by helping people share knowledge and learn through virtual communities

5. Virtuality = “distance” (requires asynchronous communication) computer representation of information different from reality (alternate representations increase comprehension and exploration) sharing experiences and perspectives flexible organizational structure to meet changing conditions [Mowshowitz 1995]

6. Focus: Virtual Communities around Professional Societies Community Members Researchers Practitioners Instructors Students Organizations serving the community (non-profit; for profit) Aspects Community interested in a specific domain Virtual communities larger than just society membership Supporting systems could be hosted by the society

7. Example Tasks (of individuals) learning about the community domain learning about relevant people in the community teaching a course finding materials on a research topic mentoring members in research or learning developing software using community research developing/selling software to serve community

8. Example Community Tasks (e.g., within a professional society) running a conference conducting elections writing newsletter / submitting to the newsletter making the budget proposing & running a task force recruiting new society members

10. Approach Concept Building regarding knowledge and learning within virtual communities Study testbed communities Prototype tools Prototype procedures Evaluate –virtual communities –learning and effectiveness –the prototype tools and procedures

11. Outline Motivation Virtuality Research Approach Knowledge & Community Learning & Community Virtual Community Issues Research Questions C-KLASS Tools & Prototype Evaluation Conclusion

12. Community Knowledge Resides in... documents (published papers, reports, photos, videos, lesson plans, syllabi, etc.) discussions decisions conceptual models formal educational modules workflows/processes people’s expertise links/relationships among all these

13. Knowledge & Community Community is important for knowledge Social Network Theory: –people develop through exposure to others [Wellman 83] Socially Distributed Cognition: –sharing generates new, more complex knowledge [Cicourel 1990] –shared knowledge becomes a public good [Kollock 1999]

14. Learning & Community constructivist, social activity occurs through collaboration [McCown & Driscoll 1995] occurs through knowledge building [Vygotsky 1962] Knowledge Building: contributing to, authoring, discussing, sharing, exploring, deploying collective knowledge base [O’Neill & Gomez 1994; Perkins 1993]

15. Virtual Community Issues Sustainability Communities need: a clear purpose [Preece 2000] sufficient social value (users, information, resources) continued adoption, use and contribution by a critical mass [Rice 1990; others]

16. Virtual Community Issues continued size (scaling up) diverse membership (time in community, experience, skills, education, language,…) requires effective user interface & tools how to promote virtual community infrastructure? how to manage infrastructure?

17. Outline Motivation Virtuality Research Approach Knowledge & Community Learning & Community Virtual Community Issues Research Questions C-KLASS Tools & Prototype Evaluation Conclusion

18. Research Questions: Virtual Community Structure What structural components characterize a healthy community? How should VC be structured to promote knowledge sharing & learning? How to adapt technologies to support structural components?

19. Research Questions: Knowledge and Learning How do different people create, understand, reuse, and learn from knowledge? Kinds of knowledge & memory to support? How do knowledge & learning improve effectiveness? How to support knowledge-sharing, learning and memory?

20. Research Questions: Improving Effectiveness What activities do members do? Barriers to knowledge-sharing and learning? Interfaces and media to improve activities?

21. Research Questions: Sustainability & Scalability How to promote? How will members “buy in”? How to scale? How the community should manage the infrastructure? Factors for sustainability? Providing on-going feedback for managing and sustaining?

23. Outline Motivation Virtuality Research Approach Knowledge & Community Learning & Community Virtual Community Issues Research Questions C-KLASS Tools & Prototype Evaluation Conclusion

24. Developmental Research No integrated tools to handle the diverse forms of knowledge sharing and learning. No procedures for how to use such an infrastructure effectively. --> Community-KLASS prototype (knowledge, learning and sharing support)

26. Prototype Architecture Digital Library: Multimedia Document Services Asynchronous Discussion Tools (Groupware) Integration Discussing a document

27. Prototype Architecture Digital Library: Multimedia Document Services Asynchronous Discussion Tools/Groupware Hypermedia Services (tours, annotation, linking) Integration Annotating a discussion Tours of documents and discussion comments

28. Prototype Architecture Digital Library: Multimedia Document Services Asynchronous Discussion Tools Hypermedia Services (tours, annotations, links) Processes/Workflows Integration Annotating and discussing a community process

29.

33. Prototype Architecture Financial Transaction Support –charging for services (membership, workshops, training modules, copyrighted materials, supporting products) –Marketplace may facilitate creation, participation, and sustainability for a larger community Digital Video –form for representing knowledge –saves time in communication

34. Evaluation focus on individual-level and community-level Action Research: work actively with participants Propositions/hypotheses and measures Formative Evaluation to assess/improve tools (requirements analysis, usability testing) Summative Evaluation to assess usage, impacts, satisfaction (direct observation, interviews, surveys, usage profiles) Pilots on ALN community

35. Contributions in-depth technical and social analysis of supporting knowledge-sharing and learning within virtual communities tools: integrated C-KLASS environment procedures approach for evaluating virtual communities

36. Further Research room for lots of collaboration regarding issues and tools approach applies to other communities (educational, within companies, government- sponsored) synergies with geo-local community informatics

37. In Conclusion Why do people participate in virtual communities? –to attract customers/clients –for amusement –to socialize; find comfort (medical communities) –to network, build contacts –to improve what you do (job, personal) –find information/solve problems/learn from others ==> collaboration, knowledge-sharing and learning underlies most of these directly or indirectly Research Question: How best to support this?
