The more the child develop his abilities in communicating others by benefiting from the different opportunities , situations , playing and practicing physical activities in physical education lesson , the less aggressive his behavior be specially in primary school . The current research aims at .1. The effect of cooperative learning in lessening the violent behavior for female and male pupils .2. Effect of cooperative learning in developing some basic skills for pupils .To achieve the aims of the research , the researcher made the following hypotheses . 1. Statistically significant differences are found between the means of pupils scores in pre and post tests of violent behavior .2. No statistically significant differences found between the means of pupils scores in pre and post tests for some basic skills . 3. No Statistically significant differences are found between the means of pupils scores in post test for some basic skills . The researcher used empirical model due to its appropriateness . The sample consisted (40) pupils representing fifth primary pupils iThe 2004-2005) the strategy was applied in (16) educational units for each group . The application lasted (8) weeks divided into two units for the group comprising (20) pupils . The following statistical means were used . (mathematical means , standard deviation , T-test for two independent samples , T-test for two correlated co-efficient , and percentage . The results were : 1. Using cooperative learning did lessened the aggressive behavior of students in the experimental groups via the moral differences in preened post tests with a bias toward the post test. 2. Moral differences were found between the post tests in lessening aggressive behavior using cooperative learning methodology in favor of second experimental tai group (female) 3. Team games didn't lessen aggressive be heavier only but increased accuracy at some games studied specially females . 4. Statistically significant differences are found in post test between male and female pupils in some basic skills with a bias towards the first experimental group while the score of second experimental group was higher in other skills . Given the results above , the researcher recommend : holding symposiums and specialized conferee to wry school staffs to cooperative learning to lessen aggressive behavior in teaching physical education .
