Etude didactique d'une activité de conception de protocole expérimental en chimie, supportée par un environnement informatique dédié. Etude de cas d'Educ@ffix.net

Abstract : This thesis highlights the necessary knowledge and learning acquired during an experimental design task in chemistry with the assistance of an ILE (Intelligent Learning Environment).
We focused on the capacity of last year of high school pupils to design an experiment, by using the ILE named Educ@ffix.net, which answers the following problem: “determine the concentration of a substance with a spectrophotometric method”. We attempted to identify the nature of the difficulties met by the pupils, in order to distinguish those related to the discipline from those related to the context. We also studied the chosen strategies as well as the role attributed to the artificial tutor by the pupils during their task. The thesis also studies the acquisition related to the experimental design task with the dedicated ILE. For this propose, we located theoretical and procedural knowledge necessary for the pupils in their task and highlighted the relations performed between a procedural knowledge and an associated theoretical knowledge. The obtained results underline that (1) the studied ILE enables the pupils to achieve the required task, (2) misconceptions of the pupils and the previous didactical contract involve difficulties for them during the experimental design task, (3) theoretical knowledge necessary to the construction of procedural knowledge is not always controlled by the pupils, (4) theoretical course available for the pupils in this ILE and the artificial tutor feedbacks often lead to a discussion within the pair which helps in the success of the task and in the build of procedural knowledge.
