Strategien bei Problemen mit rekursiver Lösung

Recursion is not only a means for describing mathematical concepts, it is also an important problem solving tool in both mathematics and computer sciences. Recursion is the object of interest in our research project. In this article, we are going to report on an investigation aiming at the identification of strategies 7th and 8th graders use while coping with the recursive TOWER OFHANOI problem. Our hypothesis is that there are preliminary concepts for the concept of recursion which may vary for different students. We will describe some preliminary concepts in this paper.
