students had to pose problems based on interesting stories. For these 13 tasks,
students were required not only to pose questions or problems but also to justify their
answers by writing the mathematical solutions of the constructed problems or the
mathematical equation, which corresponded to their own problems.
The tests were administered to the students by the researchers in five 20-minute
sessions. Prior to the administration of the test, which lasted ten working days, one
researcher visited the classes involved in the project and worked with the students on
problem solving for approximately 40 minutes.
