APPRENTI GÉOMÈTRE, AN INSTRUMENT FOR LEARNING GEOMETRY AND MAGNITUDES MEASUREMENT

The technological developments influence more and more the didactics of mathematics. Numerous researches are led to determine the gains and the optimal conditions of the use of these new tools of education. In this setting, the Centre de Recherche sur l'Enseignement des Mathematiques (CREM) (Nivelles, Belgium) produced a software of dynamic geometry, named Apprenti Geometre, primarily devoted to the learning magnitudes, fractions, measurements and geometry. To deal with these various fields, it proposes two different “working environments”, two different “geometrical spaces”. It was also conceived as an original complement to paper and pencil context. Two years of experimentation with children from 10 to 12 allowed to assert some positive changes in the learning.
