Communities, documents and professional geneses: interrelated stories
Résumé
This chapter aims to deepen the documentational approach of mathematics didactics, whose main concepts have already been presented (Chap. 2); the documentational approach, as outlined in Chapter 2, illuminates the importance of the collective aspects of teachers' documentation work. By nature, teaching involves aspects of collective work, but the development of digitalization fosters it. This chapter articulates the frames of communities of practice and of the documentational approach, defining the concept of community documentation genesis . We develop a case study, concerned with an online association of secondary school mathematics teachers, designing and sharing resources. Drawing on evidence from this case study, we explain the interactions between community geneses, community documentation geneses and professional geneses.
