Experimental Study On The Effect Of Physical Exercise On Junior High School Students' Self-control And Academic Performance

Research purposes:This study is based on previous research,design the experimental teaching scheme,mainly uses experimental method,take the first grade students as the experimental object,take moderate to vigorous intensity exercise as a means of intervention,explore the effects of different cumulative time of moderate to vigorous intensity exercise on learning self-control and academic achievement of middle school students,and further research the role of learning self-control in physical training and academic achievement by path analysis method.Research objects and methods:On the principle of easier to get samples,the researchers choose three parallel classes of first grade students in Yangzhou as experimental subjects,the experimental classes take different time in moderate to vigorous intensity exercise intervention,Using the same teacher to conduct the physical exercise class,Before and after the experiment,all the subjects' learning self-control level would be tested by questionnaire,Using their first test scores as academic achievement pre test,final exam scores as latter test.The experimental intervention lasted 10 weeks,the test data will be counted by one-way ANOVA analysis,multi-factor Variance Analysis,repeated measurement analysis of variance,statistical linear regression method,Aim to analysis the effect of different time in moderate to vigorous intensity exercise on learning self-control and academic achievement of junior high school students,and further analysis the role of learning self-control in the relationship between physical exercise and academic performance.Research results:(1)Different time of moderate to vigorous intensity exercise on junior middle school students perform self-control strategy(F = 3.593,P = 0.03<0.05)has a significant effect,self-control feeling(F = 0.599,P = 0.599),self-control tendency(F = 0.041,P = 0.041)no significant influence(P>0.05).(2)Different time of moderate to vigorous intensity exercise on junior middle school students academic achievement scores(F = 2.389),Chinese(F = 1.918),maths(F = 1.306)and English(F?1.444)has no significant influence(P>0.05).(3)The experimental group 2(LLCI = 0.5279,ULCI = 0.5279)compared with control group,the learning self-control significant indirect effect on academic performance.Research conclusions:(l)Moderate to vigorous intensity exercise has a positive impact on learning self-control strategy for junior high school students,the cumulative time accounted for about 60%in total time has best effect.(2)Moderate to vigorous intensity exercise has a positive impact on the academic performance of junior high school students on the theoretical level,but the actual effect is not significant.(3)Learning self-control is the mediation variable that physical exercise has an impact on academic performance.Especially the learning self-control strategy is significant.
