Abstract
The role of the computer environment on the problem solving processes is investigated in two kinds of situations in geometry: (a) situations in which the computer giving “objective” feedback is used as a tool and (b) situations in which the computer provides an aid based on an evaluation of the performance of the student (guided activity). In the first kind of situations, we analyze to what extent the constraints and feedback of a computer environment may affect the solving processes and the kind of solution elaborated by the student. After presenting the general principles underlying what an intelligent help provided by a computer environment can be, an example is proposed in the case of a specific geometrical task for which a prototype “Hypercarré” has been designed.
