Seventy-seven second year mathematics education specialist undergraduate students from Buca Faculty of Education, Primary School Education Department took part in the research. These seventy-seven students formed two classes (2A and 2B) one of which was randomly chosen to be the strategy group, the other forming the control group. The results of students who took extended periods of absence throughout the study were not taken into consideration. For this reason, slight changes in the number of participants can be seen in the results of the study.
