The paper presents a research on how to understand, study and improve students' school culture in case of problem solving in mathematics education. This issue, although of utter importance nowadays, is rarely defined and studied on its own.
The author presents an ongoing research in which she analyses situations within the frame of the Theory of didactical situations with the aim to gain a better insight into the conditions under which the approach to problems and their solution are transformed; in other words, to study tools that can transform students' school culture and to evaluate their didactical effects in the perspective of a mathematical activity.
