L'activité conversationnelle d'un jury de validation d'acquis : analyse interlocutoire de la formation d'un concept potentiel

In this contribution, authors try to give an interlocutory analysis of a particular verbal and work situation: a face to face activity of acquired knowledge validation panel. The analysis is made in order to verify the hypothesis that conversational activity, that realises an evaluative activity, is both the place and the instrument of the construction of a potential concept. Vygotski (1934/1997) calls “potential concept” the meeting between a concrete meaning, developed in action, with a “scientific concept”.
