Modeling Collaborative Learning Activities on e-Learning Platforms

The scenarization of educational activities, especially those that are going to take place within elearning platforms, has for a number of years represented a major challenge for groups working to favor the emergence of educational standards. In this paper we describe a meta-model, LDL (Learning Design Language), to formalize scenarized activities. We particularly highlight the correct adaptation of this meta-model for modeling various collaborative situations.
