Apport de l'étude conjointe de systèmes dynamiques libres et commandés dans la compréhension des concepts d'équilibre et de stabilité

Abstract : The concepts of balance and stability are very important in Control (control systems theory) and more generally in all the domains using a systemic approach aiming, among others, at the understanding or at the implementation of regulation mechanisms (biology, economy, electronics, chemistry, etc.). We were able to notice a relative lack of mastery of these concepts at the students, including after control systems courses, as well to the university as in engineering school. The understanding of the equilibrium concept have been investigated a lot by the research in chemistry education, but enough little in mechanic education and essentially from the point of view of the mastery of the academic knowledge (essentially declarative and procedural one). Yet, our work shows that the students’ (mis)conceptions relative to this concept call on, in a not insignificant way, the non-academic domains and also especially the concept of stability. On one hand, our work consisted in trying to understand the reasons of the difficulties observed from the study of the students’ conceptions and possible factors which could influence their development and, on the other hand, to design and propose a classroom sequence based either on the Didactical Engineering (Artigue, 1988) and the Conceptual Camps Theory (Vergnaud, 1990) at the level of engineer's education, in order to start a conceptual change. This conceptual change was measured by a quasi-experimental design based on pre and posttests.
