三种常见力的教学是高中物理教学的基础,其中包含着纷繁复杂的知识点,往往给教师的“教”和学生的“学”都带来了很大的困扰.布鲁纳的认知结构理论强调教学要让学生积极、主动地去掌握学科的基本结构,这种结构具有整体性、联系性、层次性等特性,教师在三种常见力的教学中应体现这些特性. The teaching of three kinds of common forces is the basis of physics teaching in senior high schools, which contains a wealth of complicated knowledge points, which often bring great troubles to teachers ’teaching and students’ learning. The theory of cognitive structure in Na emphasizes that teaching should enable students to master the basic structure of the subject actively and initiatively. The structure has such characteristics as integrity, connection and hierarchy. Teachers should reflect these characteristics in the teaching of three kinds of common forces .
