Etayer le travail des élèves avec la plateforme LabBook pour donner davantage de sens aux activités expérimentales réalisées par des élèves de premières S

Abstract : The thesis work involves an analysis of the experimental design activity carried out by students of junior year of high school in sciences using a TEL environment (Technology Enhanced Learning). It aims at understanding how they relate to knowledge and to the experimental approach established by both student and teacher.The thesis gives an account of how the students mobilizes their knowledge and it measures the influence of learning supports proposed by a TEL named LabBook. It also focuses on how the teacher deals with the difficulties encountered by students.Regarding that matter, a didactic engineering was already modelled as part of the Theory of didactical situations (Brousseau, 1986). This engineering focuses on the thematic of "genetic" and more specifically on "the expression of the genetic heritage" - a problematic area for most students. The analyses deal with the students’ productions, their answers to questionnaires (pre-test and post-test) and the teacher-student interactions produced throughout the work in the situation.This work highlighted the role of experimental design in changing the students' knowledge system and the evolution of their knowledge about the gene concept and expression of genetic information. The scaffolds implemented in the LabBook platform offer the students a potential for the implementation of experimental design. Teachers themselves dealt with the difficulties encountered by their students by implementing various aids. The study of these scaffolds allows the development of useful recommendations to improve the LabBook platform so as to help students overcome their learning difficulties.
