This contribution aims to examine the dynamics that have emerged from a collaborative research-training approach having relied on collective interviews, in order to shed light on the growing phenomenon of the professional integration of foreign-trained teachers in Quebec schools which seems problematic in various aspects. A conversation analysis was used to identify how the expertises of a research culture and professional cultures come together to serve a knowledge co-production process that seems relevant by the two communities concerned. Three dynamics have (...) been identified : the development of a comprehensive posture, the production of new adjusted interpretations, and the affirmation of its actor’s competency. Their highlighting leads us to reflect on collaborative design and animation strategies that served the co-production of knowledge process. (shrink)
