In this paper, aspects related to discourse structure like message chaining, message date and categorization are used by teachers to coordinate educational forums in the AulaNet environment. These aspects can be computationally analyzed without having to inspect the content of each message. This analysis could be applied to forums in other educational environments.
Humans act collaboratively in a community with mutual understanding of others’ roles in the context of an activity. Collaboration is not productive when mutual understanding is insufficient. This paper proposes “Intellectual Reputation” as a recommendation that is useful to find a right person for a right role in the creation and inheritance of organizational intellect. Intellectual reputation defines...
To facilitate shared understandings of several models of collaborative learning, and collect rational models of effective collaborative learning, we have been constructing a system of concepts to represent collaborative learning sessions relying on existing learning theories. We call the system of concepts Collaborative Learning Ontology, and have been extracting and representing models inspired by...
In our research on social interactions taking place in forum-type tools that virtual learning communities use, we have found that the users have the following particular temporal behavior: they answer generally some messages situated in different threads in a very short time period, in a digest-like way. This paper shows this work pattern through a quantitative study and proposes an integration of...
We have implemented a novel peer-to-peer based environment called Comtella, which allows students to contribute and share class-related resources. This system has been implemented successfully in a fourth year undergraduate course on Ethics and IT. The intermediate results of the ongoing experiment show a significant increase in participation and contribution in the test version in comparison with...
Internet-based virtual learning environments allow participants to refine their knowledge by interacting with their peers. Besides, they offer ways to escape from the isolation seen in the CAI and ITS systems. However, simply allowing participants to interact is not enough to eliminate the isolation feeling and to motivate students. Recent research in Computer Supported Collaborative Learning has...
