Program of Research
3 years - 2004-2007 Purpose: develop a model of virtual learning
communities (VLCs) that is grounded in practice Do elements of terrestrial communities exhibit
themselves in virtual learning communities, and dothey inform our understanding of how thesecommunities contribute to learning environments?
How do contextual, pedagogical, social and cultural
issues influence participation in virtual learningcommunities?

Theoretical Underpinning
Social capital (SC) in virtual learning communities(VLCs) is a web of positive or negative relationshipsamong learners
In the context of VLCs, SC serves as:
A framework for researchers to understand the flow of information and knowledge in a community A conduit for information and knowledge sharing among
learners An enabler of interactions that encourages peer-help and can
encourage lifelong learning and socialisation A lubricant for building trust, shared understanding and
collaboration among learners based on reciprocal actions

Theoretical UnderpinningsTypical Indicators of SC
Interaction A mutual or reciprocal action between two or more agents determined by the number of messages sent and received
AttitudesPeoples general perception about each other and how such perceptions relate to interaction inthe community
Community typeThe type of the environment, tools, goals, and tasks that define the group
Shared understanding A mutual agreement/consensus between two or more agents about the meaning, orunderstanding of an object or each other
AwarenessKnowledge of people, tasks, or environment

Theoretical UnderpinningsTypical Indicators of SC
Demographic awarenessKnowledge of an individuals demographic information (country of origin, language andlocation)
Professional cultural awarenessKnowledge of background training, skills and competences
Knowledge task awareness Knowledge about someones capability to perform a given task Capability awareness
Knowledge of peoples competences and skills in regards to a particular task
Norms and social protocolsThe mutually agreed upon acceptable and unacceptable behaviours in a community
Trust A particular level of probability an agent uses to assess the action of another agent

Research Questions - Year 1
How do patterns of online interaction in thecourse inform our understanding of thecatalysts of community?
What is the nature of learning that emerged inthese formal learning environments Are the proposed features of community
manifest in online communication in formal virtual learning environments?

Analysis
*Structural Features Size and complexity of network Density and intensity of interactions
*Interactional Features Kinds of content exchanged in interactions The exchange flow or the directedness of the resulting interaction
*From Fahy, Crawford, & Ally (2001)
Community Features Evidence of social capital (trust, awareness) Observations about nature of learning Evidence of elements of VLC from model

Nature of Learning
Categories emerged from data Learning is multivariate and diverse within the
community - categories are tentative and share variance
Casual observation that there were significantdifferences between two versions of the course, and thecourse that emphasized online discussions andasynchronous events demonstrated qualitatively
different types of learning

Preliminary results: Learning Sharing experiences the dominant expression of learning
The prominence of feedback was, to a large extent, builtinto the design of the discussions
Participants constantly provided feedback to each other There is a reasonable level of shared understanding,
argumentation, evaluation, elaboration, inquiry andreflection
Discussions are normally sustained for a certain periodof time (no measure of persistence yet)

Future Track individual intensity/involvement over time. What are the characteristic elements of learning in
VLCs? What are effective learning strategies in VLCs? Is there any variation in the quality of discussions
generated through synchronous and asynchronousinteractions in VLCs?
How to develop a BBN model of learning in VLCs thatcan be used to understand the nature of learning in
VLCs?
