PCK(Pedagogical Content Knowledge)is a necessary knowledge for teachers'professional develop-ment,which has not been paid attention to in the field of early childhood physical education so far.Based on this,the research method of procedural grounded theory was used to construct a structural system of preschool teachers'pedagogical content knowledge of physical education and to verify the structure by combining with the analysis of videos of preschool teachers'participation in the competition.The results showed that the teaching knowledge structure system of physical education for preschool teachers included four aspects of knowledge of subject mat-ter,knowledge of pedagogy,knowledge of children and knowledge of environmental contexts,21 categories of basic theoretical knowledge of kindergarten physical education,children's sports safety,physical activity con-tent,children's wrong movement recognition,formulation of physical development plans,establishment of physi-cal activity goals,understanding of physical activity content,teaching characteristics,teaching methods and strat-egies,teaching feedback,teaching evaluation,teaching organization form,teaching time,children's interest in sports learning,and differences in children's sports learning styles,children's movement skills foundation,chil-dren's physical and mental and movement development laws,children's sports cognition,teaching scenarios,kin-dergarten scenarios,community scenarios and etc,as well as 66 concepts and 421 sentences.This structure com-prehensively describes the pedagogical content knowledge in physical education that preschool teachers should have in physical education teaching with a complete system.
