Tabulae: educational groupware for learning geometry

One way to encourage students to think about their own mental models in Mathematics, especially in dynamic geometry (DG), is to allow them to investigate and manipulate variables, by changing their values and trying to observe how they behave. The sharing of individual perspectives also helps students to converge to a common understanding about the subjects discussed. In this paper, we propose a collaboration model for learning geometry, where the combination of the approaches, (learning through experimentation and collaborative learning) provides a rich environment that allows interactions between a student and an object, interactions among students, or interactions among groups of students. This paper describes Tabulae, an educational tool designed to tackle the problem of teaching Math using DG and synchronous communication within computer networks.
