针对教学的预设性与生成性要素,从分析教学主体、体育教学主体入手,阐述了体育教学主体的特殊性和体育教学实践活动的独特性,同时认为体育教学的本质是生成的,预设性是教学生成性的一个部分,这个观念更新对于解决当下存在的过于强化课前“教学设计”和课中“放羊式教学”两个极端问题是一个新的尝试。 In view of the pre-formative and generative elements of teaching, starting from the analysis of the subject of teaching and the subject of physical education, this paper elaborates the particularity of the subject of physical education and the uniqueness of the practice of physical education. At the same time, the essence of physical education is generated. Sexuality is a part of teaching creativity. This concept renewal is a new attempt to solve the two extreme problems of pre-class teaching design and class teaching of sheep-raising teaching.
