| Junior high school students are in the second growth and development of the peak stage,their body form and function rapid development,emotions and interests are constantly enriched and differentiated.Sports ability is the most basic part in the process of cultivating the core quality of junior physical education.It is the comprehensive ability shown by students in the process of participating in sports,which is mainly reflected in the basic sports ability,physical strength,and the mastery and application of special sports skills.However,under the influence of exam-oriented education and modern lifestyle,the sports ability of junior high school students has been declining year by year.Under this background,the concept of sports homework was put forward.Physical homework can help students consolidate the knowledge and skills learned in physical education class,cultivate the habit of physical exercise,develop athletic ability,and form a lifelong concept of physical education.In this regard,this paper aims to explore the influence of different sports homework on the athletic ability of junior high school students,enrich the theoretical research system of sports homework,provide practical methods for the design and implementation of junior high school sports homework,and also provide theoretical support for the promotion and development of sports homework.Using the methods of literature,expert interview,questionnaire survey and experimental research,40 students from classes 801,802 and 803 in Choujiang Middle School of Yiwu City were selected as the experimental objects.Among them,class 801 was used as the control group for daily PE teaching without PE homework.Class 802,as experiment group 1,assigned practical sports homework in the spare time of daily PE teaching.Class 803,as the experimental group 2,assigned practice + written sports homework in addition to daily physical education.Through the experiment of 15 weeks,explore the influence of different sports homework on the sports ability of junior high school students.The results are as follows:(1)The basic athletic ability of both the experimental group and the control group was improved.The scores of the experimental group in men’s 1000 m running,sitting forward bend and volleyball mat were significantly higher than those of the control group after the implementation of sports homework(P < 0.05);There was a significant difference between experimental group 2 and experimental group 1 in men’s 1000 m race(P < 0.05),and experimental group 2 was obviously better than experimental group 1,but there was no significant difference between the two experimental groups in other events.(2)Both the experimental group and the control group made progress in physical fitness.The BMI of the experimental group was significantly different after the exercise homework(P <0.05),and the scores of the three items of sit up,sit forward bend and volleyball exercise were significantly higher than those of the control group(P < 0.05);There was a significant difference between experimental group 2 and experimental group 1 in volleyball exercise performance(P < 0.05),and experimental group 2 was obviously better than experimental group 1,but in other items,there was no significant difference between the two experimental groups.(3)Both the experimental group and the control group had improved in the aspects of special motor skills.After the implementation of sports homework,the scores of the experimental group in volleyball serving,rules and judging methods were significantly higher than those of the control group(P < 0.05);There were significant differences between experimental group 2 and experimental group 1 in rules and judgment methods(P < 0.05),and experimental group2 was obviously better than experimental group 1.To sum up,sports homework can promote the athletic ability of junior high school students,and the effect of practical + written homework is better.The following suggestions are made based on the research conclusions:(1)Optimize teachers’ understanding of PE homework;(2)Improve the operation system and enrich the operation content;(3)Promote a unified operation platform by combining modern educational technology;(4)Combined with the local situation,create characteristic operations. |
