• Resumen

  • Computer algebra systems (CAS) make us think about WHAT and HOW we teach mathematics. In this article we focus on the HOW by developing a two level framework for understanding, categorfr.i11g, and planning the use of technology, in particular CAS, in teaching and learning mathematics. First we look at two kinds of support a tool can give: automation and compensation. Second we look at four pedagogical approaches for teaching and learning mathematics which are greatly facilitated when using CAS properly: trivialization, experimentation, visualization and concentration. Based on this framework we introduce the scaffolding method as a pedagogically justified sequence of using and not using technology to achieve certain teaching goals.
