اثر استراتيجية التعلم التعاوني على التحصيل الدراسي في مادة العلوم الطبيعية- دراسة شبه تجريبية على عينة من تلاميذ السنة اولى متوسط -

The current study aims to know the effect of using the cooperative learning strategy on the achievement in natural sciences for first-year intermediate students compared to the usual teaching method. In this study, a quasi-experimental design known as the tribal and post-measurement design was used for two groups, one of them is control, and the other is experimental. The experimental group and the number of its pupils (32) students, and the other section represented the control group and the number of its pupils (32) students. After completing the teaching period, which lasted (4) academic weeks for each group, with an average of two lessons per week, the post-test was applied to the achievement test on two groups. The results of the research hypothesis test showed that there were significant differences between the mean scores of students at all levels and for the achievement test as a whole in the pre and post tests for the experimental group in favor of the post test. The results of the research hypothesis test showed that there were significant differences between the mean scores of the experimental group students and the control group students in the post application of the achievement test as a whole and at the following levels: remembering, analysis, in favor of the experimental group. The results of testing this research hypothesis showed that there were no statistically significant differences between the mean scores of the experimental group students and the control group students in the post application of the achievement test at the level of understanding and application level.
