Among the most important results: 1- The educational program using the Jigsaw strategy has a positive effect on athletics competitions for the age group (11-12) years. 2-The educational program using the Jigsaw strategy has a positive effect on estimating the child's behavior for the age group (11-12) years. 3-The educational program using the Jigsaw strategy saves effort and time for learners and teachers.
