L'orientation des enseignants de mathématiques et sciences sur les modèles constructivistes et transmissivistes d'enseignement. Les résultats de la recherche Prisma sur les enseignants valdôtains des niveaux primaire et secondaire

The article analyzes the nature of teaching and learning processes developed by teachers of Aosta Valley by checking the presence of transmissivistes or constructivist orientations and trying to investigate the differences in the approaches of teachers in mathematics and scientific disciplines. The data used are from the PRISMA research, conducted by the Department of superintendent of schools of the Autonomous Region Aosta Valley and Aosta Valley University by a survey administered to all primary school teachers and secondary first degree in the area. The analysis measures the transmissivity or constructivist orientation that teachers may have developed from the scale attitude offered by TALIS (Teaching and Learning International Survey, OECD 2008). Using factor analysis, based on the answers to these points, two factors were extracted, related to the concepts of constructivism and transmissivisme. The factorial scores were then used to verify the existence of different approaches between teachers of mathematics in relation to other disciplines in the different levels of education.
