Les décisions didactiques d'un enseignant dans un EIAH : étude de facteurs de type histoire didactique

Abstract : This thesis work deals with micro-decisions (Comiti, Grenier & Margolinas, 1995), namely teachers’ decisions in class in relation to the subject they have to teach. Our aim is to contribute to the development of a TEL (Technology Enhanced Learning) that can guide teachers in their decisions.These decisions are analyzed through a specific field: decimal number system in cycle 2 (Tempier, 2013). For the description of this field we have chosen the Anthropological Theory of Didactics (Chevallard, 1998), more specifically an implementable version: T4TEL (Chaachoua, Ferraton, & Desmoulins, 2013), (Chaachoua & Bessot, 2016).Margolinas’s model about structuring the environment (2004) is used to take into account different learning activities during a teaching session. So, teachers’ micro-decisions are studied in relation to their teaching project, their observations of pupils’ activities, their knowledge of epistemic and didactic history type.Our research method is a didactical engineering whose specificity is to involve teachers in the analysis and design stages. In this engineering we have designed (1) a simulation of counting material “counting rods”: “SimBûchettes” ; (2) a bank of exercises for “SimBûchettes” and (3) an experimental device. This device is composed of, a simulation tool whose fundations are didactic – “Simbûchettes” -, on the pupils’ side, and on the teachers’side a classroom orchestration tool which allow teachers to consult and organize pupils’ activities in real time – Chao Framework’s instantiation (Wang, 2016) for “Simbûchettes”.Via our device we have access to teachers’ actions, and we can know what information has been consulted in pupils’ work. Then we can infer the micro-decisions teachers have made.This device has allowed us to observe teachers’ decisions in a primary class (CE1, 7 years-olds) during one school year and refine our teachers’ micro-decisions model.
