title: Influence of physical activity on concentration among junior high-school students.
abstract: The level and quality of concentration were tested before and after each lesson in one class session. Two of the four classes participated in physical education activities, and the other two studied science. Each subject matter was studied the beginning and at the end of the school day. The research design was 2 x 2 x 2 factorial (two subject matters, two times of the school day, and as a repeated measure two times of test for each group at the beginning and end of each lesson). The level and the quality of concentration found at the end of each lesson were significantly higher than at the beginning. The subject matters did not influence concentration. It may be concluded that the time of day was the main influence on concentration, so teachers' claims against physical education activity lessons can be rejected. The increase in concentration toward the end of the lesson implies the need for careful lesson planning or even the consideration of increasing duration of lessons.
