Intuitive Geometry by Emma Castelnuovo: still contemporary in the digital devices’ era
Keywords:Castelnuovo, DGS, GeoGebra, Intuitive geometry
Emma Castelnuovo has been one of the most influent innovators of the Italian mathematics Education. She published for the first time her book “Intuitive Geometry” in 1949, by which she presented a completely new perspective of geometry teaching/learning. Castelnuovo’s work had a strong impact on mathematics education. Nowadays, educational innovation is often confused with the use of digital devices; so it would seem that intuitive geometry by Castelnuovo, based on material models manipulation, is destined to have no more room in our classes. In this paper, we support the opposite conclusion: dynamic geometry softwares allow performing those explorations, which have always been promoted by Castelnuovo but with some differences. A classroom activity in grade 6 is used as example to support our conclusion.
