CONCLUSIONS
The observed results from the creation and the use of GeoGebra environment have shown that:
Problem-posing situations foster the development of strong interest in the use of GeoGebra environment for creating and solving mathematical problems. They change strongly the role of the trainees - from passive consumers of knowledge to active creators of knowledge.
Students understood the problems and the methods for creating or solving problems more deeply by using technology.
The use of the GeoGebra environment stimulates the mathematical creativity among the students and the problems, which they created, have creative character.
