Research on the Optimization of the Physical Education Teaching Mode Based on Cluster Analysis under the Background of Big Data

With the rise of digital campuses, online learning platforms, and the improvement of educational technology, the interaction between teachers and students has entered a new stage. Especially under the influence of CSCL (Computer Supported Collaborative Learning), computer-assisted collaborative learning, and E-learning (Electronic Learning) network digital learning that emerged in recent times, new technologies are changing the way people learn. Students’ learning is not limited to one-way absorption of knowledge taught by teachers, and the interaction between students and teachers, students and students, and the interaction between students and the teaching environment are increasingly appearing in modern teaching classrooms. This paper optimizes the physical education management based on the clustering algorithm under the background of big data, uses the popular Java language to write codes to realize all the functions of the algorithm, and uses some small examples to prove the correctness of the fuzzy clustering algorithm sex. The algorithm reads a file through the input and output streams FileReader and BufferedReader. The content of the file is the relevant information of the physical education mode. It gives the methods to calculate the cluster center (i.e., the center of mass), calculate the distance, correct the fuzzy classification matrix, and display the matrix. (i.e., output matrix), conversion to deterministic classification method, calculation of classification coefficients, and basic functions such as average fuzzy entropy. According to the data, if the FCM clustering method is not used, but the previous average method is used as the evaluation basis, there will be results that we do not want to see, but if we use the FCM algorithm, the evaluation result is that what we want to see is more specific. From the analysis results, thematic teaching + basic teaching seems to be the most popular mode of physical education.
