For this purpose, specific research questions were set : Are there any differences in attribution change in problem solving according to strategy method? Are there any relation between attribution and problem solving. To prove the effects of the program, pretest-posttest control group design was applied. And the differences on attribution of efforts were analyzed using independent t-test. The results of the study were as follows : there were statistically significant differences between the experimental group and the control group in the attribute of efforts.
