Research and Analysis of Evaluation and Expansion of Physical Education Teaching System Based on Internet of Things Communication

Abstract

Under the influence of China’s education reform, the assessment and evaluation of physical education have gradually attracted more and more people’s attention. Teaching evaluation ignores the development of students’ sports lifestyle. The article uses principal component analysis to establish a teaching quality evaluation model and design an extensible teaching evaluation system. The article uses box plots to reflect the characteristics of data changes, which can clearly draw differences between samples. Three variables of experimental class, reference class, and standard class are set up to conduct controlled experiments, and statistics are made from the survey results of the 2018-2019 school year physical education evaluation student evaluation. The experimental results indicate that after using the system, students’ learning satisfaction and enthusiasm have been greatly increased, and students’ weekly exercise time and sports items have also increased. Before and after the use of the teaching evaluation system, the students’ satisfaction with the evaluation system and the degree of movement recognition were tested. The results show that the system has a positive effect on the students’ evaluation satisfaction and movement recognition.
