Supporting Collaborative Learning Activities with IMS LD

Currently more and more higher education institutes implement CSCL (computer supported collaborative learning) environments to facilitate collaboration among their students. However in order to support effective and reusable collaborative learning design we need represent collaborative learning activities in a formal way so that they can be recognized and processed automatically by the computer. In this paper we present IMS LD, a process modelling language to formalize collaborative learning activities, and then discuss the limitations and extensions of the language in modelling collaborative learning activities.
