【Abstract】 As key implementers of basic education reform, physical education teachers’ development of pedagogical content knowledge(PCK) directly impacts classroom teaching quality. This study, grounded in grassroots physical education classrooms, employs a case analysis method and a PCK framework to dissect the practical characteristics and formation pathways of their classroom practices. The findings propose insights for teacher development: professional ethics serve as the guiding principle, disciplinary knowledge forms the foundation, and a “practice-reflection-innovation” cycle constitutes the developmental mechanism.更多还原
