Identification et observabilité de la compétence d'interaction: le désaccord comme microcosme actionnel

This paper presents an investigation of disagreement sequences understood as an actional microcosm that allows us to zoom in onto the development of interactional competence. An analysis of interactional data from French L1 classrooms in French speaking Switzerland is presented, emanating from two levels of schooling (lower and upper secondary). The analysis (a) identifies a series of observables relating to interactional competence, (b) opens a window onto aspects of its development across time and (c) sheds light on the communicative cultures at work in the two school contexts.
