La conception codisciplinaire de métaressources comme appui à l’évolution des connaissances des professeurs de sciences : les connaissances qui guident un travail de préparation pour engager les élèves dans l’élaboration d’hypothèses ou de conjectures

摘要

Sciences curricula give nowadays an increasing place to enquiry based learning methods involving teachers of different disciplines. The implementation of such approaches supposes that teachers develop teaching situations that engage students in a process of elaborating hypotheses and conjectures. We articulate epistemological, didactical and ergonomic approaches in order to study the knowledge that allows teachers to design such learning situations. We make two crucial choices in this study : the choice of the design period, focusing on the time of learning situations design; the choice of the design context, focusing on a collective of teachers in mathematics, physics and sciences of life and Earth.We study within this group the interactions between teachers and their consequences, in term of evolution of knowledge, that allows teaching situations to develop. The interactions that the study focuses on are social interactions between teachers and interactions between teachers and shared resources within the group. The analysis of these interactions show evidence about the influence of two levers that concern the evolution of studied knowledge. The first is the conception of specific resources that we call metaresources: metaresources are resources that lean to a reflexive position regarding the activity itself or its effects. The second is the concept of co-disciplinarity as a form of collective work. Co-disciplinarity favours cooperation between disciplines, keeping and articulating each particular epistemology
