This chapter explores a particular form of the "transparency" concept: designing styles of interaction that explicitly reveal the pedagogical foundations of the ECS. Reflection tools and activities can help the learner to internalize an active model of learning. This model would emphasize the active, heuristic and negotiated nature of learning, by opposition to the schoolmade passive idea of what learning is. The system's model of learning cannot be accessed in an abstract way but only through the instantiation of this model by the learner's behaviour.
