The present study focuses on the observation of learning processes as they emerge in the context of conversations among two students in three successive tasks designed to foster conceptual change in proportional reasoning. The three tasks were set according to a pre-test treatment post-test paradigm. In the pre-test and the post-test tasks, the two students solved individually several items in the presence of an experimenter. In the treatment task, the two students worked as a dyad to solve similar items; they (...) used a balance to check their conclusions and subsequently continued solving the items when the weighing did not match their expectations. We adopt a micro-genetic approach and develop new analytical tools to observe what happened in the conversation (both socially and cognitively). Throughout the three successive tasks, we observed the interplay between tools, peers, experimenter, and task demands and how they are managed through the rules of conversation. We identified four processes that involved the emergence of new high-order strategies from coordinated actions distributed among peers, the guidance of the experimenter in coordinating actions, and ways the participation in solving a previous task was actualized in a successive one.

Cet article porte sur l'étude processus sociocognitifs qui aboutissent à la co-construction d'une procédure de résolution de problème dans un contexte d'activité médiatisée par un logiciel. Son objectif est de voir comment, dans un contexte d'utilisation d'un logiciel de « fabrication assistée par ordinateur » , de jeunes adultes parviennent à gérer les aspects cognitifs et sociaux . À partir de cette illustration empirique, nous dégagerons un ensemble de propositions: - méthodologiques: comment appréhender le travail collaboratif dans des situations médiatisées (...) par un logiciel? - théoriques: quelles compétences et quelles dynamiques interactives sont activées dans de telles situations?The paper examines the sociocognitive processes that lead to the construction of a procedure for problem solving when software is invovled. The aim is to see how, in the context of the use of computer-aided manufacturing software, young adults are able to deal with cognitive and social aspects. This empirical illustration will be a basis for the extrapolation of a series of questions: - on methodological level : how should we approach collaborative learning in situations where software is used ? - on a theoretical level : which skills and interactive processes are brought into play in such situations ?
