The ninth grade sample consists of 74 female students who were divided into two groups (37 control and 37 experimental) , and the tenth grade sample consists of 86 students who were divided into two groups (42 control and 44 experimental) . After processing the data statistically by (ANCOVA) , the results showed a statistically significant difference at the level of significance (a ≤ 0.05) due to the variable of the group in all the tests, and the differences were in favor of the three experimental groups which received the developed units in the three classes. In the light of these results, a number of recommendations are suggested.
