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 howfeedback 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.
