Une ingénierie didactique fondée sur une démarche d'investigation avec simulation pour enseigner les ondes mécaniques au lycée

Abstract : The thesis begin with a report, Based on a review of the literature, about the difficulties of the pupils and the students in relation to the concept wave. This report is strengthened by our empirical study in master's degree. The objective of our work is to build, and to make out to test, a didactic engineering based on an investigation so proposing an education differ from the custom resting on an IT simulation. After an introduction of the principles and the interest of the didactic engineering, our work is organized in four parts.The first one contains an epistemological analysis and a historic of the concept of wave, where our results show the emergence and the perseverance of the obstacle substantialist. Then, an analysis of the sessions of ordinary education of the concept of wave is realized within the framework of the theory of the joint action in didactics. This analysis highlights the nature of the practices in this Tunisian terminal classes of high school and shows the limits of such an teaching, as we consider transmissif. The cognitive analysis of the key concepts (vibration velocity and wave front) allows to support our report on the difficulties met by pupils. An analysis of the field of constraints closes this first part. The second part consists in justifying choices made to develop an educational scenario based on a situation of type PCDR's inquiry, constituted of four moments: forecast, Confrontation, Resolution and discussion. The third part is reserved on one hand, in the detailed description of the methodology of search and its various levels of analysis and, on the other hand, in an analysis a priori of the practical session of teaching of type PCDR. To finish, the fourth part proposes an analysis of the activities led during the session on the waves in a suburban high school of Tunis and an evaluation of the educational scenario. The obtained results are satisfactory with regard to compared with our waits. Indeed, the discussions of the pupils translate a real interest to solve certain situations of proposed inquiry. Furthermore, the analysis of the results of the post-test shows that the session of teaching with approch by PCDR contributed to the improvement of the number of the correct answers of the pupils and their ways of reasoning.
