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)
Der Einsatz von Rechnern, insbesondere von mobilen Rechnern kann die traditionelle Präsenzlehre bereichern. In diesem Beitrag wird zunächst die besondere Eignung mobiler Rechner für die Unterstützung der Präsenzlehre vorgestellt. Aufbauend auf der Darstellung verschiedener Szenarien der Rechnerunterstützung für die Präsenzlehre werden wichtige Fragen des(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)
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)
This work introduces an approach to discover collaboration partners and adequate advising experts in a workplace-embedded collaborative e-learning environment. Based on existing papers dealing with work task and user context modeling, we propose the following steps towards a sucessful collaboration initiation. In the beginning, the user’s current process(More)
