Un modèle de résolution de problème en interaction didactique

Résumé (en anglais)

The use of language is much wider than its mere communicative function, specific to phatic conversation (speak to talk) or to informative dialogues (speak to inform or to get some information). Hence, this article aims at establishing to what extent the didactic interaction (or conversation) is a verbal activity imagined by two individuals in complex situations with a view to obtaining a transformation of the present situation with the help of the interlocutor. So, we will be able to see that the operating model is definitely a pragmatic one: this model turns the dialogue into a practical activity. Our research is based on a new vision on argumentation considered as a phase of conflict resolution superimposed (and not interposed) to problem solving. However, the model we present has its limitations: it does not tackle in a more thorough way the analysis of argumentation acts.
