Abstract
This chapter discusses the use of a Dynamic Geometry Environment for fostering students’ introduction to mathematical proof. Grounded in the theory of semiotic mediation, it explores, on the one hand, the link between computational tools and the personal meanings emerging from their use in classroom activities and, on the other hand, the mathematical notions that are the object of instruction. The discussion uses three interrelated perspectives—the epistemological, the cognitive, and the didactic—to elaborate on findings from a number of longstanding teaching experiments in secondary school classrooms. Some illustrative examples are presented, drawn from research studies carried out in previous years and still in progress.

Following Sinclair and Robutti (2012), I use the term “dynamic geometry environment.” As the authors write, since at least 1996, this term has been used over dynamic geometry software “to underscore the fact that we are dealing with microworlds (including pre-existing sketches and designed tasks) and not just a software program.” (p. 571).
- 3.
The term artefact refers to any generic product of human culture purposefully designed to act or interact in a human setting.
- 4.
An exception is that of mathematical induction. But mathematical induction is very rarely presented in comparison to other modalities of proving, which are commonly considered natural and spontaneous ways of reasoning.
- 5.
Actually a DGE provides a larger set of tools, including for instance “measure of an angle,” “rotation of an angle,” and the like. This implies that the whole set of possible constructions does not coincide with that attainable only with ruler and compass. See Stylianides and Stylianides (2005) for a full discussion.
