Similarly to H. Freudenthal, E.
Fischbein and many other mathematics educators, we consider the main way to improve the teaching of mathematics to lie in the change of a teacher's educational style towards the development of pupils' creativity and intellectual autonomy. In our interpretation, it means towards scheme-oriented education based on the theory of generic models which is briefly described.
On the basis of these ideas, the tool for the analysis of a teacher's teaching style is developed. The tool and its application is described in Jirotková's article in this issue.
