Abstract

This research paper presents a study that deals with the choice of a scientific reasoning and the validated hypotheses from several researchers and didacticians such as: Ben Romdhane who proved that the representation of 3D objects helps the learners in creating a mental image in space; to organisation methods of pedagogic and didactic means that provide the teacher with the technology, not only to disrupt the learner’s manner of thinking and mobilize his cognitive resources, or to conduct him to understand and explain the functioning of a complicated mechanism or an abstract phenomenon; but also to give the learners the opportunity to make good use of the learning results in various contexts.
