However, at present, the research on the core literacy of physical education in the field of school physical education is still in the exploratory stage. The research results are mostly inclined towards the construction of theoretical systems, and there are relatively few research results that combine diversified physical education teaching practices and applications. A reasonable and complete physical education teaching system has not yet been formed. The teaching links such as teaching objectives, organization methods, teaching means, and teaching evaluation lack innovation and effectiveness. In the practice of high school physical education teaching, the implementation and operation of teaching objectives, teaching stratification, teaching methods, and teaching evaluation are relatively single, making it difficult to achieve the comprehensive development of motor ability, healthy behavior, and sports morality. How to deeply integrate teaching content under the guidance of the core literacy of physical education, interact and coordinate the advantages and characteristics of various teaching methods, and use diversified physical education teaching practices to stimulate students' interest in sports, improve their motor skills, cultivate their willpower, and then develop healthy behaviors and establish the awareness of lifelong physical education has become an important topic of current high school physical education teaching reform. Especially in the high school stage where students have greater learning pressure, traditional single teaching practices are difficult to stimulate students' motivation to participate in sports, and it is also difficult to achieve the comprehensive development of motor ability, healthy behavior, and sports morality. Therefore, in this predicament, diversified physical education teaching practices are an effective method to stimulate students' interest in sports, improve their motor skills, develop healthy behaviors, cultivate their willpower, and establish the awareness of lifelong physical education.
