| In recent years,the physical health of primary school students and the economic pressure of parents’ out-of-school education and training have been a hot topic of concern from all walks of life.In order to solve this problem,the General Office of the CPC Central Committee and The General Office of the State Council issued Opinions on Further Reducing the Homework Burden and out-of-school Training Burden of Students in Compulsory Education on July 24,2021(hereinafter referred to as "double Reduction").Subsequently,the corresponding policies and opinions issued by the state proposed to create favorable conditions for primary school students’ physical exercise through home-school coordination,in order to enhance students’ physical health.With the implementation of the "double reduction" policy,the time of students’ physical exercise increases,and the development of home-school coordination of physical exercise also welcomes a new opportunity.Therefore,this paper takes the "double reduction" policy as the basis,takes the home-school coordination as the background,and studies the improvement of primary school physical exercise as the purpose.In this paper,the collaboration between primary school physical exercise and school under the "double reduction" policy is taken as the research object,and the main research methods are literature,questionnaire,Delphi,field investigation,interview,mathematical statistics and logical analysis.After two rounds of expert discussion by Delphi method,the questionnaire design of "Strategic Research on home-school Coordination of Primary School Physical Exercise under the" Double Reduction "Policy" was finally determined.The questionnaire mainly conducted a systematic research and analysis on the current situation of home-school coordination of primary school physical exercise under the "double reduction" policy,as well as the situation of students’ physical exercise and home-school coordination.Finally,through the analysis of influencing factors,correlation and regression,the following results are obtained:Through correlation analysis,it is found that there is a significant positive correlation between students’ off-campus physical exercise time and parents’ knowledge of physical education(r=0.379,P<0.001),parents’ physical exercise time(r=0.396,P<0.001)and parents’ and students’ joint physical exercise time(r=0.255,P<0.001).There was a negative correlation with whether they participated in sports interest classes(r=-0.124,P<0.001)and whether they had sports homework(r=-0.065,P<0.05).Regression analysis shows that students’ off-campus physical exercise time and parents’ understanding of physical education knowledge β=0.183(t=4.317,P<0.01),parents’ physical exercise time β=0.227(t=5.341,P<0.01),parents’ and students’ common physical exercise time β=0.119(t=3.905,P<0.01),whether sports homeworkβ=0.067(t=2.275,P<0.05)had a positive correlation,and whether to participate in sports interest class β=-0.017(t=-2.417,P<0.05)had a negative correlation.Through the analysis of the results,the following conclusions are drawn: under the "double reduction" policy,the coordination of primary school physical exercise schools in Liaocheng has achieved certain effects:(1)After the "double reduction" policy,the Liaocheng government actively implemented relevant policies to help the "double reduction" implementation;(2)Schools teach students according to their aptitude and respect their differences;(3)Teachers and parents have a strong demand for co-parenting.There are also some problems,mainly include:(1)the school does not implement the national policy in place,the lack of policy guidance;(2)Different groups have insufficient understanding of off-campus physical exercise;(3)There is no linkage between the school and the home of physical training;(4)The shortage of sports teachers;(5)The supervision and evaluation mechanism of home-school coordinated physical exercise is not perfect;(6)Risks and hidden dangers of physical exercise.In order to better realize the coordination between home and school in primary school physical exercise under the "double reduction" policy,the following strategies are proposed:(1)adhere to the policy guidance direction and strengthen the implementation of local policies;(2)Facing up to the value of physical exercise and clarifying the educational goal of cooperative education;(3)Establish the respective responsibilities of the family and school,and promote the construction of the family and school cooperative education community;(4)Capacity expansion and efficiency improvement,equipping and equipping sports teachers;(5)To improve the collaborative supervision and evaluation mechanism of physical exercisers and schools;(6)Establish long-term supervision and prevention mechanism. |
