Mesure du potentiel des tâches d’interaction. Expérimentation et perspectives méthodologiques

We present an experimental study designed to assess the potential for acquisition of different interaction tasks performed in pairs by learners of French as a foreign language. After recalling the principles of interactionist paradigm, and his conception of the role of the corrective feedback and the tasks, we present our experimental study protocol, and a summary and discussion of key results. We finally propose a general discussion of the role that experimentation and quantitative analysis can play in the research in second language acquisition. In this respect we defend the idea that analysis of language production should not be restricted to qualitative and descriptive analysis, but must also be quantitative
