Assistance au tuteur. Prototype d'un système pour l'adaptation de situations d'apprentissage aux apprenants

Research works presented in this article are dedicated to the tutor instrumentation in distance collaborative learning situations. We develop an on-line tutoring model to identify tutor’s role among the other actors, his/her degrees of freedom and means which he/she has at his/her disposal during the course. We lean on this model to develop, in an iterative process, a generic assistance system for tutor. This system is based on an ontology modelling the tutoring components (actors, their characteristics, activities, their parameters and resources). An inference engine uses the ontology to deduct advices to the tutor. The aim is to help him/her to adapt learning situations to learners and working groups by taking into account their behaviours and interactions. By analysing tutors’ functions, we develop pedagogical rules. We conclude the article by a feasibility study of the system and its evaluation by tutors. MOTS-CLÉS : formation à distance, apprentissage collaboratif, modélisation du tutorat, système d’assistance au tuteur.
