It is also important to customize the learning process according to the skills and requirements of the each group of learners. We present in this study an algorithm called LeCA (Learner’s Clustering Algorithm) to grouping learners according to their profiles. For this, we defined a model of a user profile as well as metrics to calculate the distance between different profiles and also between a profile and a group.
