Abstract:

Especially the experiments in those classes where CAS is available in every working situation, in other words, not only in the classroom but also at home and in the exam situation, the hypothesis was confirmed that cognition must be seen as a functional system which encompasses both man and the tool as well as material and social context. Accordingly, the tool "computer" is not only an amplifyer of human performance, it can also change thinking qualitatively and can generate new ability.
We especially observed this significance of the tool "Computeralgebra System" in the field of functions.
