The role of computer algebra in the change of teaching and learning
mathematics is very important.
Computer algebra enables solving of many problems in such a
way that after entering of the problem (e.g. equation) the final solution
appears immediately.
But from the point of view of the learning process, such a capacity is not
always very useful. Especially if one of the aims is learning to know the
process of solution.
The presentation will handle the possibilities of computer algebra
in a step-by-step solution of problems. For example, the
solving of an equation in a way that tranformations between the problem
and the final solution would not be lost. An important question is with
which topics it is reasonable to use such a step-by-step approach and
which topics might be better dealt with using a one-step solution process.
The examples are based mainly on Maple.
