Experimental Study On The Teaching Of "Upgrading And Downgrading" Stratified Teaching Mode In Badminton Selected Courses In Sports Colleges And Universities

According to the existing literature research,we can know that the existing traditional three-base teaching mode and hierarchical teaching mode can improve students' performance to a certain extent,but the overall effect is ideal,which is not conducive to the grasp of individual students or small groups of students,and has certain restrictions on the improvement of their learning ability in the future.This study USES the method of literature,mathematical statistics,logical analysis,experimental method and so on to study the teaching effect of "promotion and demotion" stratified teaching mode in badminton courses in sports colleges.The purpose of this study was,with support from the existing theory of modern education,and according to the specific situation of the students,construct suitable for the teaching experiment,the feasibility of "demotioneing run" layered teaching mode,teaching effect comparison analysis with the traditional teaching mode,provide theoretical basis for the badminton teaching in colleges and universities,and provide a reference for other curriculum reform.In this paper,40 badminton students of social sports major of class 2017 of shandong university of physical education were investigated by experimental method.The experimenters were divided into two groups,the control group and the experimental group.The experimental group adopted the hierarchical teaching mode of "promotion and demotion",while the control group adopted the traditional three-base teaching mode.The performance data of special qualities were tested before and after the experiment.Badminton sport skill level,including basic skills,including forehand serve high ball,forehand high ball,forehand pick ball,forehand rub ball;The basic steps,including four moving steps.Compare the data of the experimental group and the control group before and after the experiment,summarize the results and draw the final conclusion.According to the analysis of experimental data,the following conclusions are drawn: 1.The traditional three-base teaching mode can improve students' performance of special quality to a certain extent,but the improvement range is not large,and the overall performance is not average;2.The hierarchical teaching mode of "promotion and demotion" has a good effect on improving students' performance of special qualities,and the whole is relatively average.2.Compared with traditional teaching,"promotion and demotion" multi-level teaching mode can improve students' special quality and basic badminton skills,with better promotion results.3.Under the hierarchical teaching mode of "promotion and demotion",the overall improvement of girls' basic technical level is faster.4.The growth rate of the traditional teaching mode is basically stable,and the performance gradually increases without obvious growth range;The "promotion and demotion" teaching mode had a faster growth rate and higher performance in the fourth and eighth weeks,and there was no significant difference in the growth rate between it and the traditional teaching mode in the 12 th and 16 th weeks.5.After a long period(more than 12 weeks),the teaching effects of "promotion and demotion" stratified teaching mode and traditional teaching mode have obvious differences,among which "promotion and demotion" stratified teaching mode has more obvious effects.
