摘要：The purpose of the research was to determine the effects of 12-week physical activities based on Cooperative Learning Method on development of basic motor skills of Primary School 1st Graders. Pretest-Posttest Design, Semi-Empirical Research Method and Unequaled Control Group Methods were used in the research. To determine the effects of physical activities based on Cooperative Learning Method on the development of basic motor skills, controlling the ball with feet, controlling the ball with hands, running coordination, agility, promptness and dynamic balance skill tests were used. According to the statistical results, no significant differences were detected in pretest average values of the research and control groups in Independent sampling t-test; however, a significant difference was found in favor of the research group in posttest averages. In the t-test for Dependent Variables, significant differences were found in pretest-posttest averages in favor of the posttest values of Research Group. In pretest-posttest averages of Controls, negative significance was found in controlling the balls with hands, and no significant differences were determined in other motor skills. We believe that students are active in application process, and the long-term planned learning-teaching environments with physical activities based on Cooperative Learning Method might contribute to the development of basic motor skills.
