Personalization of learning is a complex task which objectives are manifold. One of them is to provide teachers with tools allowing them to personalize activities assigned to learners. The PERLEA project takes a step in this direction by proposing a system enabling teachers to manage learners profiles. Within this system, the Adapte module is responsible for the creation of activities adapted to a given learner. This task is performed according to the information available in the learner profile and in collaboration with teachers. Created activities are either paper and pencil worksheets or ILE-related activities. This paper describes the mechanism of the Adapte module and demonstrates how it helps teachers to personalize better learning activities.
