Using Computer Algebra Systems as Cognitive Tools
Abstract:
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.
