Group formation in CSCL environments is either done manually with little support from the system, or the system needs an elaborated model of the learning domain in order to select potential peer learners and to form learning groups in a pedagogically sound way. Our research objectives include the integration of collaborative learning into the learning(More)
D-CSCL (for Distributed Computer Supported Cooperative Learning), refers to approaches that aim at improving learning processes of groups of learners which are geographically distributed and connected by computer networks. The success of such learning technologies critically depends on sound evaluation, formative as well as summative. We first describe a(More)
A common problem of CSCL (Computer-Supported Cooperative Learning) is addressed: How can we coordinate goal-directed, effective interaction in a group of learners? We introduce the concept of learning protocols which originates in script theory. We then discuss which dimensions of cooperative learning can be supported by learning protocols and propose how(More)
In the CLear project we develop a cooperative learning system for supporting learning and training processes of co-located and distributed groups. One of the fundamental concepts of CLear is the virtual room metaphor. We discuss divergent interpretations of this metaphor each appropriate for certain aspects of the learning process. We are exploring the(More)
We conceptualize referencing as a primary means of establishing intersubjective meaning and, therefore, as an important consideration in supporting collaborative learning. What we call group cognition is a discourse-centered analysis of the interactional basis of collaborative knowledge building, establishing common ground and co-constructing shared(More)
