* Important at P <.05 level.** Measurements in which differences have been observed as a result of Tukey test.According to Table 5, there is a significant difference between the scores of the groups in pre-test (1), pro-test (2) and retention test (3) [F (2,58)= 5,658, p<0.05]. As a result of the Tukey test, it has been observed that this difference takes part between the control group students' pre-test scores and post-test scores (p <0.05).Table 6: The arithmetic mean and standard deviations of the control group students' pre-test, post-test and retention test
