This paper presents a model of collaborative telelearning and describes how coordination theory has provided a framework for the analysis of actor (inter)dependencies in this scenario. The model is intended to inform the instructional design of learning scenarios, the technological design of the telelearning environment, and the design of intelligent agents to mediate or to support the mediation of collaborative telelearning. The first section introduces the challenges of telelearning, focusing on the fluid mediation of collaborative learning activity. Computer supported collaborative learning (CSCL) and coordination theory are discussed in the second section. The third section presents the model and its use in distance learning in a strategic management course at Ecole des Hautes Etudes Commerciales in Montreal (Canada); the part of the course that the learning scenarios document utilizes Netstrat, an Internet-based strategic management simulation. Reading the model is explained in the next section. The fifth section discusses the analysis of dependencies between actors in distance learning scenarios and describes the concept of collaborative shared interdependence through a shared activity. A table presents dependencies between activities. Four figures illustrate: the Netstrat simulation game; features of the strategic management course and Netstrat; and the third year learning scenario model. (Contains 11 references.) (DLS)
