Resumen de Compass Avoidance
The talk 's goal is to analyse the conceptual implications for math education that arise from the use of computers in two precise situations:
1) As a tool for geometric reasoning ( automatic theorem proving) 2) As a replacement for ruler and compass, the paradigmatic scientific tools of school (computational geometry). The underlying thesis is that popular dynamic geometry programs such as Cabri are far from fulfilling the conceptual requirements of the 21st century elementary geometry education.
