Visualisation in teaching-leaming mathematics: the role of the computer

Abstract

This paper is centred on the study of the role that information visualisation can have in mathematics learning. A theoretical analysis is worked out in order to give account of the complex phenomena that take place in the classroom in order to allow students to construct a mental image of lhe mnthematical object involved in the activity. This theoretical analysis is the reference to study the different didactical functions that information visualisation can develop in learning process. This different functions are discussed making reference to the role that Cabri Geométre can have in the teachingllearning processes of Euclidean geometry.
