The Teaching Research Of Volleyball First Attack Tactics Under Digital Information

With the construction of healthy China,sports as a physical exercise to improve students' physical fitness,improve the body's immunity and resistance are promoted at school and at the social level.University sports is also a key hub for linking schools and social sports.Through university sports,students can develop their athletic qualities in schools and society.In university sports,volleyball is a required course for the three major sports.It has a high value for students' physical and mental health and physical fitness.The positive effect of large-scale promotion is also just around the corner.However,in the process of teaching and learning about volleyball for a long time,we discovered that how to teach volleyball match tactics is more difficult than how to operate volleyball,and the difficulty and technical requirements are also very high.Since volleyball needs a good foundation and the students' basics are uneven,there are also certain difficulties for teachers.At present,teachers' intrinsic teaching experience and methods are not sufficient to meet the needs of contemporary students.As a result,students' enthusiasm for learning has declined,and students' learning aspirations have not been met.After a long period of teachers' teaching reflections and classmates'evaluations,it has been learned that the tactical teaching of volleyball is a difficult point.This research uses digital information technology to innovate in volleyball tactics.It aims to innovate the teaching methods of volleyball tactics so as to improve teachers'teaching ability and students,ability to apply new tactics in the game,and further promote tactics to be more reasonable and scientific.development of.This research mainly uses the literature data method to carry on the cognition and the investigation to the existing volleyball tactical teaching method in the university.Adopt software engineering method to present and explain digital information tactics.Experiments were conducted on the Shaanxi Normal University team and the volleyball class of the Shaanxi Normal University.After the test,questionnaire survey method was used to investigate students' teaching satisfaction.The conclusions are as follows:1.Through the questionnaire,it can be found that whether the high-level or low-level teams use the tactical teaching under digital information technology,the degree of acceptance of students is higher than that of traditional tactical teaching methods.Volleyball tactical teaching method under digital informationization can increase the students' interest in learning,and it is more conducive to speed up the students to master tactics.2.From the high-level team experiments,the teaching method of volleyball and tactical teaching under the digital informatization is better than the traditional display teaching method.After t-test(P<0.05),there are significant differences.Applicable to tactical teaching of high-level teams.3.From the low-level team experiment,the teaching method of volleyball-attack tactical teaching under digital informatization is superior to the traditional teaching method.After t-test(P<0.05),there is a significant difference.Suitable for tactical teaching of low level teams.4.Through the comparison of the lower ball rate and the deduction rate between the high-level experimental class and the low-level experimental class before and after,it can be seen that the promotion rate of the high-level class is higher than that of the low-level team,and the volleyball tactics under the digital informationization are high.Students in the horizontal class are better than those in the low level class.The research proposal is as follows:1)According to the development of existing tactics and the physical quality of students,etc.,establish some new tactics,in order to enhance the diversity of tactics,a tactical database system should be established.2)Volleyball teachers establish a corresponding digital informationized volleyball tactical teaching platform so that more students can learn through mobile phones and computers.3)Enhance teachers' ability to use modern technology and promote the development of modern tactical volleyball.School venues should add some large projection equipment to create a good modern teaching environment.4)Teachers should develop and establish excellent courseware,give full play to the advantages of the school environment,and vigorously promote the new excellent volleyball tactics courseware.
