If teachers use few ILEs with their students, it may be because they don’t have the opportunity to act upon the available environments. To permit the appropriation of ILEs by teachers, these systems must be adaptable to the learning context and to the teacher’s pedagogical approach. To achieve this we propose a module dedicated to the teacher in the context of the AMBRE project. This module, AMBRE-teacher, allows the user to configure the ILE he wants to use. We identified the functionalities necessary to adapt an AMBRE ILE. We notably designed a knowledge based system allowing the teacher to generate the problems he wants to propose to his students in the ILE. Our approach is implemented for, AMBRE-add, an ILE proposing word additive problems in elementary school.
