As seen in Table 3, there is a significant difference between the pre and post test scores of both the experimental group and the control group. Post-test scores of both groups were higher than pre-test scores. While the second hypothesis was accepted, the third hypothesis was rejected. However, while the scores of the experimental group doubled, the score of the control group increased by about half. A covariance analysis was performed to compare the posttest scores of the experimental and control groups. Homogeneity of the regression slopes and equality of variances were tested before the covariance analysis was performed and it was seen that there was no obstacle to the analysis.
