Abstract
The article presents the concept of appropriation of knowledge in the context of educational writing. The next step is to understand which variables in a scenario are more likely to have an impact on the student apprenticeship. The research conducted is based on a university training context based on collaborative learning in line with the Claroline Connect platform. The experiment concerns 48 learners enrolled in the first year of specialized mater (multimedia pedagogical engineering), in Tetouan, Morocco divided into three experimental groups (G1, G2 and G3) distributed in 12 teams. The results concern the analysis of the appropriation performance of these teams according to the effect of their structuring by the roles, the effect of the structuring of the forum and the interaction of these two effects.
