This thesis presents an analysis of the practices of five primary school teachers when they propose opened problems during mathematics lessons. The practices are ordinary because we intervened neither in the choice of the problems, nor in the implementation of the sessions. Our analysis allows to answer questions concerning the motivations of teachers who study these problems in classroom, the implementation of sessions and knowledge which could be teach. We observed teachers during a year and organized this research within the framework of the didactic and ergonomic approach (Robert, Rogalski, 2002) while using the notions of professional gestures and routines (Butlen, 2004). This work is articulated around three parts. First, with reference to the theoretical framework of a documentational approach of didactics (Gueudet, Trouche, 2008), we propose explanations of choices made by the teachers in terms of used resources. The second part is an a priori analysis of the chosen problems, especially to determine pupils’ possible reasoning and the nature of the expected solution. The third part is an a posteriori analysis of observed sessions. She allows showing the stability (Robert, 2008) of the teachers’ practices studying opened problems in classroom. Then by identifying professional gestures and routines of the five teachers, we characterize their practices and determine two teachers’ profiles associated to study of opened problems in class.
