Resumen de The Algebraic Calculator as a Pedagogical Tool for Teaching Mathematics
Bernhard Kutzler
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.
