The Exploitation of Traces Serving Tutors for the Reconstruction of Groups within a CBLE

For several years, education has undergone numerous problems, which led researchers to focus on this issue, trying to enable the difficulties encountered during the learning process. Research on the Computer-based learning environments (CBLE) aims to meet challenges as school failure, dropout and the learners groups heterogeneity. Within the context of a remote collaborative activity, the tutor is often not able to have a global perception of the virtual class he leads, thus confronting a real problem in terms of identification of the groups that face difficulties. The exploitation of interaction traces done by the users in the CBLE and the indicators development are able to help tutor monitor the activities of his/her learners. This article presents the researches made to this regard and raises the research prospects.
