In this paper, a Project-Based Collaborative Learning (PBCL) meta-model is proposed. It allows a teacher to build up a PBCL scenario and to implement it in a learning system which is not designed to this learning method. A MDA (Model Driven Architecture) approach is described to elaborate transformation rules between the PBCL meta-model and that of the learning system. Moodle platform, used in the UIT of Laval, is the chosen case study.
