The purpose of this study is to investigate the effectiveness of cooperative learning on the development of some basic volleyball skills (normal sending, receiving, passing the ball to the opponent's area) and the experimental method (pre-test and post-test) was used for secondary school students of Tuiserkan city. 24 students (15-16 years old) were divided into two experimental and control groups of 12 people. The experimental group was divided into two groups of 6 people, each of which has three classes. The results showed that collaborative learning helps to improve the capabilities mentioned in the study.
This study is based on a two-group experimental method: one group is basic and the other is experimental. A sample of 24 people was selected from the community of secondary school students in Tuiserkan city. The sample is randomly selected. To obtain accurate results, this study is based on the test and application of specific capabilities of this sport Therefore, plyometric exercises and educational tools are used to practice the educational units. Student's equation-Pearson correlation for simple relationship-standard deviation-arithmetic mean of this study has used three different tests related to volleyball. Normal sending - receiving sending - transferring the ball to the opponent's area. All materials and tools related to the program for learning volleyball ball capabilities with cooperative learning strategy were used during class lectures in the experimental group, and this group, unlike the control group, was under the supervision of a teacher.
There are significant differences between the pre-test and post-test values of the normal sending of test and control samples, and the calculated T values are equal to 3.26 and 2.82, respectively.
There is a significant difference between the pre-test and the post-test of moving the ball to the opponent's area in the test and control samples, and the calculated T value is 4.74 and 3.53, respectively.
There is a significant difference between the pre-test and the post-test of sending in the test and control samples, and the calculated T value is 5.71 and 3.72, respectively.
After applying the Student's T test, the values of 3.82 to 4.63 were obtained, and the T value of the table is at the significance level of 0.05 and the degree of freedom is 22 equal to 2.07.
According to the tools, results and findings obtained in this study, we concluded that the cooperative learning method has a positive effect on the sample group. The difference between the tests of the training group was more than that of the control group. The difference between the post-tests of the experimental groups was also observed. Cooperative learning method is the best way to develop some basic volleyball skills.
