Prendre en compte l'interaction : de la recherche descriptive aux études d'efficacité

Evidence-based practices are at the centre of clinical and political discourse about health care. Interaction between researchers and clinical professionals is crucial in order to define and apply the best practices interventions.

In particular, the article proposes a distinction between intervention programs that use interaction as a medium to improve or facilitate language acquisition and interventions whose focus is social interaction. The discussion explores further perspectives for researchers and professionals.
