Experimental Research On The Application Of "Hierarchical And Asynchronous" Teaching Method In Primary Mini Tennis Teaching

Short tennis,also known as "Mini" tennis,is an emerging tennis sport that is suitable for early childhood tennis enlightenment training,which is made up of standard tennis venues,rules and equipment.As a beginner's entry transition,short tennis has the characteristics of small age,small site air pressure,slow flight speed,low bounce height,simple and safe,and has been loved and sought after by everyone.At present,some primary schools in China have begun to introduce short tennis.Due to the uneven quality of primary school students in terms of physical quality and technical level,this poses new problems and challenges for short-seat tennis teaching for primary school students.This is also short tennis.One of the problems urgently solved in teaching.This study takes the application of "stratified asynchronous" teaching method in the short-sentence tennis teaching of primary school as the research object.A total of 72 natural students in the fifth grade of Zhongshan Elementary School in Songjiang District,Shanghai are selected(36 in the experimental class and 36 in the control class).As a subject of experiment,the students use the forehand shot of tennis,the backhand shot,the teeing technique and the interception technique as the teaching content.According to the physiological development and movement rules of the students,the"stratified asynchronous" teaching experiment research,from the students' The technical study and mastery,physical quality,learning motivation,students' learning ability and the influence on students in different levels have been compared and analyzed in detail,exploring the advantages and disadvantages between the "layered asynchronous"teaching method and the traditional teaching method.To provide an empirical reference for improving the effect of mini tennis teaching and enriching teaching methods.The experimental conclusions are as follows:(1)After the experiment,the experimental group and the control group in the positive and negative hand hitting techniques,the teeing technique,the interception technique and the technical assessment,the four techniques were P<0.05,showing significant differences.The average performance test group of each technology is higher than the control group,which indicates that it is feasible to use the " layered asynchronous " teaching method in the short-sentence tennis teaching of primary school students,and the teaching effect in the standard and technical evaluation is better than the traditional teaching method.This is due to the "layered asynchronous" teaching method to treat the differences between different levels of students can be taught in accordance with the aptitude,step by step in the asynchronous guidance,help to improve students' interest in learning,and promote students' technical learning and mastery.(2)The "layered and asynchronous" teaching method has a positive impact on the four technical achievements of students at different levels.The main influences are as follows:the scores of the students in group A have improved significantly,from 8 before the experiment to 17 after the experiment;from group 18 before the experiment to 11 after the experiment;group C,from the experiment The first 10 people became 8 people after the experiment,and the change was not obvious.The“layered and asynchronous”teaching method has the greatest impact on the B group students with better basic scores.The traditional teaching method has little effect on the comprehensive scores of the students.(3)After the experiment,the average scores of the physical fitness indicators of the experimental group and the control group were P>0.05,no significant difference,indicating that the " stratified asynchronous " teaching method had no significant effect on the physical quality of the students.Except for the influence of climate and other factors,the physical fitness test scores of the two groups after the experiment were higher than the test scores before the experiment.(4)After the experiment,the experimental group compared with the control group students,the teacher praised rewards,interests and hobbies,achieved a sense of accomplishment,and the challenging four motivational component scores were P<0.05,showing significant differences,while exercising,body and The average scores of the three components of appearance and no motivation were all P>0.05,and there was no significant difference.It shows that the "hierarchical and asynchronous" teaching method has different influences on students' internal motivation and external motivation.The "stratified asynchronous" teaching method rewards the experimental group students with rewards,interests and hobbies,and a sense of accomplishment and challenge.The motive component has a significant impact.(5)The use of "layered asynchronous" teaching method is conducive to improving students' enthusiasm for participation,independent research,forming a habit of independent thinking,improving cooperation and interaction among students,gaining a sense of collective honor,promoting communication and improvement among students.The student's ability to learn.
