A mathematical notion, problem or algorithm should not be taught for its own sake, art for art. Thus the most important task of a Mathematics teacher is to develop the students’ way of thinking through acquiring certain frames of knowledge. All cognitive operations are essential for both understanding and problem solving. It is substantial that students should solve such exercises or types of exercises that involve several cognitive operations. Furthermore, it is important to create a motivational base. In this, interactivity provided by the use of ICT tools may play an important role. GeoGebra can provide facilities in creating these requirements. Supported with relevant research data, I would like to speak about my experiences of this matter, and I would also like to illustrate through some example programs how we can use GeoGebra in developing cognitive operations.
