提高教学质量，是学校追求的永恒主题。随着中学体育教学研究的深入，教学改革的最终目的是实现教学过程中的最优化组织形式，来提高教学质量。按学生身体健康状况和运动能力进行分组教学（按体能进行分组），是更有效地完成体育教学内容和任务的组织措施。 Improving teaching quality is the eternal theme pursued by the school. With the deepening of physical education research in middle schools, the ultimate goal of teaching reform is to realize the optimal organizational form in the teaching process so as to improve the teaching quality. Teaching according to students’ physical health and athletic ability (grouped according to physical fitness) is the organizational measure to accomplish PE teaching contents and tasks more effectively.
