This paper presents the first computer-aided experiment on learning control which took place in Europe at the Faculté des Sciences de Paris. The teaching objectives, the level and the needs of the interaction (dialogue, open answers, feedback to the student) are described in the first part of this paper. Then the computer configuration is given and the technical solutions decided are discussed. The third part of the paper deals with the man-machine communication problem to which has been given great importance in the definition of the experiment. Some examples showing either the way the course is described and put into the system or the dialogue between the computer and a student are included in the paper.
