Physical education class is the basic organizational form of physical education, which mainly enables students to master the basic knowledge, skills and skills of physical health care, realize students' ideological and moral education, and improve the level of sports skills.

The teaching task of physical education class in primary and secondary schools is consistent with the general task of school physical education, including: exercising students' bodies and strengthening their physique; Teaching the basic knowledge, technology and skills of sports; Carry out ideological and moral quality education for students. These three aspects are an organic whole and must be implemented in a comprehensive and coordinated manner. Physical education class exercises through students' physical and mental activities, and through repeated practice, learning and mastering sports knowledge, technology and skills, which is the main feature of physical education class. Another characteristic of physical education class is that students' thoughts and behaviors are more obvious in class, which provides more opportunities for ideological and moral education than other courses. In addition, physical education also includes physical fitness, bodybuilding and other factors related to aesthetic education. Emphasizing the role of physical exercise, attaching importance to moral education and aesthetic education in physical education teaching, cultivating students' habit of loving sports, and making students active, lively and happy in physical education class are the general trends of physical education class's development in modern primary and secondary schools.

The structure of a class refers to several parts of a class, the order of teaching materials, the organization of teaching methods and the distribution of time. In physical education class, I mainly engaged in various sports activities. Living things have to bear certain physiological loads and have certain intellectual activities. Therefore, the structure of physical education class should not only follow the general laws of human cognitive activities, but also follow the laws of physiological activities. The law of physiological function activities is generally divided into three stages: rising, stabilizing and falling, which reflects the general trend of the change of people's working ability.

According to the above two laws, the structure of physical education class is generally divided into: preparation part, foundation part and ending part. From the following table, we can see the relationship between each part of the class and the three stages of human working ability.

The three parts of the above course are the basic structure of physical education class. As for the specific structure of each part, it varies with the specific tasks, teaching materials, students' situation and number, and operating conditions (venues, equipment, seasonal climate, etc.). ). The consistency of the basic structure of the curriculum and the unity of the diversity of the specific structure constitute a complete physical education class structure. In order to strengthen the organization of teaching, physical education class in primary school can also divide the preparation part into two parts: "beginning" and "preparation", which become four classes, and there is no essential difference between them. At present, three-stage courses are widely used. However, in some countries, the structure of physical education class is not strictly divided.
