Etayage de l'activité de conception expérimentale par un EIAH pour apprendre la notion de métabolisme cellulaire en terminale scientifique

Abstract : The thesis work involves a scaffold of the experimental design activity carried out by high school students in scientific activities using a TEL system (Technology Enhanced Learning).This type of activity promotes learning, but it is also a complex task that leads to difficulties identified in the literature. The situation highlights a specific cellular metabolism, the alcoholic fermentation, this topic being studied in high school biology classes. Students have to design an experimental procedure to highlight this metabolism.The first step of the thesis consisted in knowledge modelling for designing an experimental situation in biology. The framework used to model knowledge, is the Anthropological Theory of Didactics (ATD) and more precisely the praxeology model (Bosch & Chevallard, 1999). An epistemological analysis has been done in order to identify difficulties in this situation: difficulties related to knowledge and also to experimental procedure.A structured procedure was modelled into steps, actions and parameters, which takes into account difficulties identified a priori and implemented in a web environment named LabBook,.This TEL system offers fixed scaffolds in order to help students in an experimental design activity.The situation implemented in LabBook has been tested in three biology classes in high school, during two sets of experimentation. The analysis is based on the students’ productions and their answers to questionnaires (pre-test and post-test).The results analysis showed that the experimental design activity promotes learning and changes students’ conceptions. Regarding design experiment, the pre structuration helps students to produce relevant and communicable procedures.This reveals that students are able to use the pre-structured experimental procedure tool in LabBook.This is a requirement for students’ errors diagnosis in order to propose automatic personalised feedbacks. We make recommendations for such feedbacks based on the praxeology model developed in this thesis.
