DÉMARCHE EXPÉRIMENTALE, VALIDATION, ET OSTENSIFS INFORMATISÉS. IMPLICATIONS DANS LA FORMATION D'ENSEIGNANTS À L'UTILISATION DE CABRI EN CLASSE DE GÉOMÉTRIE.

Abstract : WE STUDY THE DIFFICULTIES THAT TEACHERS EXPERIENCE IN LEARNING TO USE CABRI IN THEIR TEACHING, AS SEVERAL STUDIES HAVE REVEALED, IN ORDER TO IMPROVE TEACHER'S TRAINING. WE USE A TRIPLE THEORETICAL FRAME, WITH THE ANTHROPOLOGICAL THEORY OF DIDACTICS (CHEVALLARD), THE INSTRUMENTAL APPROACH (RABARDEL) AND THE THEORY OF SITUATIONS (BROUSSEAU). WE HAVE IMPLEMENTED A LONG INGENIERY, WITH AN INTENSIVE COURSE ABOUT GEOMETRIC PROBLEM SOLVING WITH CABRI, A PERIOD OF COACHED PRACTICE, AN INTENSIVE COURS ABOUT TEACHING WITH CABRI, AND A PERIOD OF COACHED PRACTICE. WE SHOW THAT CABRI'S NEW OSTENSIVE OBJECTS REQUIRE A PRAXEOLOGICAL RECONSTRUCTION TO ASSIMILATE THE DYNAMICS AND THE COMPLEXITY AND RICHNESS OF RELATIONS AMONG OBJECTS, AND THAT DESPITE A GOOD ASSIMILATION OF A MATHEMATICAL PRAXEOLOGY, TEACHERS EXPERIENCE DIFFICULTIES IN PRACTISING A DIDACTIC PRAXEOLOGY BASED ON VALIDATION.
