چکیده (انگلیسی):

This paper is a revision of the field of the so called “Computer supported collaborative learning”, showing its potentialities as well as some of the problems. It also makes an analysis of the types of task that are well designed to be collaborative, in the thread to find “genuine interdependent” tasks and not just subtasks that are only joined. At last, it raises some difficulties encountered when trying to think collaborative learning as a form of group proximal development zone.
