The Costa model educational technique was used in the research to try to determine its effects on teaching some defensive and attacking handball skills. The research sample included (40) students from Misan University's third-stage Faculty of Physical Education and Sports Sciences. The sample members were divided randomly into two experimental and control groups, with (20) individuals assigned to each group, and members of the experimental group then underwent a three-week educational programme, and a tribal exam was used to determine that the two groups (experimental and control) were equivalent before the program's execution in terms of the two variables of offensive and defensive skills. The pre-test results revealed no statistically significant differences between the two groups' average performance for two independent samples. The offensive and defensive skills tests were used to collect the data needed to answer the hypotheses, and after processing and application to the research sample's participants in the pre- and post-tests, the data were statistically analysed using the T test to get the following results: There are statistically significant differences in offensive and defensive skills between the average performance of experimental group members who learned using an educational approach using the Costa model and the average performance of control group members who did not receive any of their learning in favor of theexperimental group. In conclusion, a number of recommendations and proposals were developed.
