LOs = learning objects

A major problem of education is the adaptation of the didactic content to the student’s knowledge and to his particular way of learning. Tutoring Systems address this challenge by recommending learning objects appropriate to each student’s learning styles. However, in the context of e-learning, Tutoring Systems present their own challenges. One of these challenges is to find learning objects that cover the concepts that the learner needs to learn. More precisely, the ideal is to recommend LOs that cover all and only the concepts that the student needs to acquire.
