MotivationWhy 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?

Goal

Increase effectiveness

by helping people

share knowledge and learn

through virtual communities

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]

Focus: Virtual Communitiesaround 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

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

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

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

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

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]

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]

Virtual Community IssuesSustainability

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]

Virtual Community Issuescontinued

• 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?

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?

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?

Research Questions:

Improving Effectiveness

• What activities do members do?

• Barriers to knowledge-sharing and learning?

• Interfaces and media to improve activities?

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?

Testbed Communities

• Asynchronous Learning Networks• ALN Research Site - pilot site

• Hypermedia • ACM SIGWEB

• Human-Computer Interaction• ACM SIGCHI, British HCI Group

• Human Sciences (formally Home Economics)

• Kappa Omicron Nu Honor Society• Pennsylvania Dept. of Education

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.

• Conceptual Knowledge Structures

• Others...

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

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

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

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

In ConclusionWhy 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
