Abstract
Dynamic Geometry Computer Software allows the user, teacher or student, to realize simple or complex geometric constructions. In this way one can directly interact on the screen with geometrical objects. The straightforward way of having students working with such environments is to let them become familiar with geometrical facts, usually called theorems. For more than a decade this approach, based e.g. on Cabri-geometre, has been developed in many countries. In this presentation I will focus on some basic mathematical situations, that can be tackled by students. I will also show how teachers in Physics are using Cabri as a modelling tool for illustrating phenomena's in Optics, Mechanics or Astronomy, where mathematical modeling is crucial. The presentation will end with some more advanced examples in mathematics.
