The thesis aims to investigate the integration of theory into practice in PE team teaching. On the basis of related researches and in accordance with the samples of team teaching in Nine-Year Integrated Curriculum, the study will follow the patterns of team teaching home and abroad (organizing teaching groups, designing teaching plans, detailing teaching procedures, implementing teaching activities, and mutual evaluation) to demonstrate "single-subject team teaching", "interdisciplinary team teaching", "multi-subject team teaching", "circle team teaching", and "key-subject team teaching".
