| The feedback of sports technique means that teachers and students understand the effect of students’ learning technical actions through communication and feedback,which can help students grasp the skills more intuitively,and take effective measures to improve its technical level.In addition,the feedback of sports technology can help teachers master the students’ movement skills better,so as to provide more effective guidance and help for students.Therefore,to choose more intuitive,more timely feedback of sports technology can effectively improve the level of students’ skills.Research purposes: mobile phone video feedback teaching is a kind of teaching method based on the function of mobile phone video recording and playback.It can record the whole process of students’ participating in the skill learning through the real-time shooting of mobile phone,and can also play the students’ training situation and actions in the process of video playing,which is more flexible and intuitive in the teaching mode,students can also get more information through video feedback to enhance their understanding and mastery of skills and knowledge.Video teaching has been widely used in various fields and has become an important carrier of teaching means in the new era..Methods: this paper mainly adopted the teaching experimental method,selected 12pre-experimental badminton player and 16 formal experimental sports training college 2022 undergraduate students,of which 8 were experimental group and 8 were control group,before and after the experiment,there was no significant difference between the experimental group and the control group in body shape,physical fitness,badminton footwork-related test indexes.At the end of the 8-week teaching intervention experiment,the physical quality,two-point footwork in the front field,two-point footwork in the back field,and kill-net footwork of the two groups of students were compared,the effect of the mobile phone video feedback on badminton special footwork was judged by skill consistency score,E-Prime accuracy and reaction time,and classroom satisfaction.The results showed that:(1)there was no significant difference between the experimental group and the control group(P > 0.05)in the physical fitness test,such as three-minute rope skipping,15-meter back-step running,meter-word turn-back running,squatting and multi-direction step jumping;(2)the results of special footwork test showed that the two-point footwork in the front field in the experimental group was 0.67 s better than that in the control group,and the killing-net footwork in the experimental group was0.49 s better than that in the control group The results of two-point step test showed that there was significant difference between the experimental group and the control group(p <0.05)(4)there was a significant difference between the experimental group and the control group(p < 0.05),and the scores of the experimental group were 0.5 points higher than those of the control group There was no significant difference in the level of self-cognition between the experimental group and the control group,but there was significant difference in the level of classroom satisfaction between the experimental group and the control group(p < 0.05).The results show that:(1)the effect of improving students’ physical quality is very obvious in both the experimental group and the control group(2)compared with the control group,the students in the experimental group mastered the basic footwork of badminton more deeply,and the improvement of the accuracy and reaction time of judging footwork by E-Prime was obviously better in the experimental group than in the control group;(3)compared with the control group,the scores of the two-point forward step,two-point back step and net-killing step were higher in the experimental group(4)the results of the questionnaire show that the mobile phone video feedback teaching makes the students master the ability more comprehensively,students’ ability of cooperation and communication,initiative of self-study and ability of correcting mistakes in technical actions have been improved obviously. |
