What is Mathematics Laboratory

This chapter is focused on the GeoGebra Institute of Torino, Italy (http://www.geogebra.unito.it/), founded in July 2010 at the Dipartimento di Matematica dell’Università di Torino (http://www.dm.unito.it) and operating under the auspices of the human resources of the association La Casa degli Insegnanti (http://www.lacasadegliinsegnanti.it/PORTALE/), which is in charge of organising courses for teachers. GeoGebra is a dynamic geometry software that has had a large diffusion in educational and academic institutions in recent years. This wide diffusion opens new fields of research in mathematics education, in continuity with other software of the same kind, such as Cabri-Géomètre or The Geometer’s Sketchpad. The main research questions deal with teaching practice, pedagogical and methodological choices, teacher education, and teaching/learning experiments at different school levels. Furthermore, several issues relating to the learning of mathematics with GeoGebra, in the context of research and teaching practice are highlighted.
