The integration of flipped classroom into university physical education teaching reform practice from the perspective of multimedia

With the development of multimedia, the flipped classroom is deeply loved by educators with its unique, flexible and efficient features, which meet the requirements of physical education reform from a multimedia perspective. In this paper, we first use a genetic algorithm to arrange the physical education course information in a real number coding way to form chromosomes and initial populations. Then the individual fitness F is determined, the outstanding parent individuals are selected, the chaotic crossover and chaotic mutation operations are performed, and the end conditions are judged. According to the calculation of the fitness function, this ensures the diversity of the population and also eliminates the conflicting course plan programs. Then, 83 students from two classes at Guizhou Normal University were used as experimental subjects to explore the effect of integrating flipped classroom teaching into physical education, and the volleyball skills of students in the experimental and control groups were tested in the form of teaching-examination separation. The results showed that there was a significant difference between the volleyball skill test results of students in the experimental and control groups t=2.071, p=0.042, less than 0.05, indicating that the volleyball skill level of the experimental group was better than that of the control group after experiencing 32 credit hours of volleyball teaching. This study promotes the reform of physical education teaching and is of great significance to the development of physical education. © 2023 Bin Feng and Jingjing Zhao, published by Sciendo.
