In the context of the personalization of learning, we want to provide teachers with generic tools enabling them to personalize activities they offer learners. The PERLEA project aims at conceiving a system enabling teachers to manage existing learners' profiles. In this system, the Adapte module proposes activities suited to the abilities highlighted in their profiles. Theses activities are either paper and pencil worksheets or activities on an ILE. This paper presents the principles of the Adapte module, its architecture and the implementation which we have done.
