Using Computer Algebra Systems as Cognitive Tools


We describe how Computer Algebra Systems (CASs) can be used as cognitive tools in a learning environment. In particular, we show how a CAS is employed in {\activemath}, how different types of CAS-exercises are designed, and how feedback can be produced with the help of the very same CAS. We report the results of a first preliminary formative evaluation of {\activemath}' CAS-exercises in a university course and some modifications of {\activemath} caused by this evaluation.
