Abstract: On July 24, 2021, the General Office of the CPC Central Committee and the General Office of the State Council issued the Opinions on Further Reducing the Homework Burden and Off-campus Training Burden of Students in Compulsory Education (referred to as the "Double Reduction" policy).In order to interpret the deep impact of the "Double Reduction" policy on the health development of school sports and teenagers, as well as the response to school sports, 6 domestic experts were organized to conduct special discussions on the "'Double Reduction' policy and the development of school sports" in the form of written discussion.Ren Hai from Beijing Sports University believes that the core problem of school sports is how to make students become active from passive participation.The "not serious""play" carries a very serious educational mission and provides indispensable physical and spiritual nourishment for the healthy growth of children."Play" is the soul of school physical education in the compulsory education stage.Therefore, the advantage of the policy of "Double Reduction" should be taken to let "students enjoy fun in physical exercise" and turn "passive sports" into "active sports" through "play".Mao Zhenming from Beijing Normal University holds that the practical problems of Chinese education and the profound meaning of "Double Reduction" should be examined from the perspective of China's development in the new era."Double Reduction" policy is not only the "opportunity" needed to be grasped but also the "danger" to be vigilant on.Students should be made up for the physical health through "Double Reduction" policy, the specialized schools were built with the integration of sport and education, "teaching, regular practice and often competition" of sports courses were realized and students' academic evaluation of physical education and the evaluation for entrance examination were promoted, combining physical education with labor, national defense, security, science and technology and art education.Tang Yan from Shanghai University of Sport believes that school physical education should use the actual time from the potential time obtained from the "Double Reduction" policy.That is, sports departments in higher education, school sports research institutes and physical education teaching and research institutions at all levels should closely cooperate to establish the integrated sports skills level standards, according to the sports construction from the basic action skills to special sports skills.Primary and secondary schools must break the existing physical education curriculum arrangement to carry out physical education teaching; rather, they should follow the principles of sports interest to organize teaching, and those graduate with obvious sports advantage can be recruited to be the primary and secondary school physical education teachers, who could replan the way of campus sports activities, with reference to the new school sports work requirements of "teaching, regular practice and often competition".Wang Xiaozan from East China Normal University considers that with the "Double Reduction" policy, school sports should do "three stick-to": stick to the main position of school sports to make the sports field a warm place; stick to the bottom line of avoiding youth physical health's declining and share the good of school sports for all; stick to the function and value of sports and let students enjoy the "fun" of sports.At the same time, "three breakthroughs" should be achieved: break through the inherent educational thinking, that is, "traditional sports" should be transformed to "new era sports"; break through the inherent teaching mode, i.e., we should begin from "lone fighting" to "home-school-social linkage"; break through the inherent evaluation system, that is, "single evaluation" should be changed to "comprehensive evaluation".Shao Weide from Zhejiang Normal University thinks "a main body, two main lines, three guarantees" of the quality of extracurricular sports activities path should be formed, namely, "sports club" as the main body, "sports competitions" and "hierarchical management"as the main lines, and "policy regulations", "school support" and "internal and external school cooperation " as the guarantee to improve the quality of extracurricular sports activities, based on the "Double Reduction" policy for the reform of extracurricular sports activities.Xu Agen from Shanghai Xinzhong Senior High School believes that, the practice strategy of school physical education should be optimized in terms of sports teaching concept and methods, physical education curriculum and content, school sports activities and competitions under the background of "Double Reduction" policy, so as to lay the foundation for "building a good ecology of education and promoting the all-round development and healthy growth of students".
