In order to help learners take advantage of the MOOC (Massive Open Online Course) they follow, we propose a tool to recommend to each of them an ordered list of “Leader learners” to support him during his learning process. The recommendation phase is based on a multicriteria approach for the periodic prediction of the “Leader learners”. Given the heterogeneity of the learners' profiles, we recommend to each of them the appropriate leaders by using the Euclidean distance and the demographic filtering technique.
