This oral intervention in Spain will present French distance education management : how LMS is supervised in order to train students. After a brief methodological introduction, I will show results consisting in the description of LMS management whose aim is to improve the learning activity of distance students. I will explain how interactions and "coopetition" are fundamental in students team building. I will end up with a discussion around three notions : effectiveness, efficiency and efficacy in learning. These three notions rely on group interactions in order to reach training objectives.
