概念形成和概念同化是学生获取概念的两种主要途径。《因数和倍数》作为一节概念课,学生主要以概念同化的途径获得,即用定义的方式直接向学习者呈现因数和倍数相互依存的关系,学习者再利用认知结构中原有的概念理解这种关系。因此,这样的概念课很容易让学生走入“模仿口述”的怪圈,缺少促使学生思维自发碰撞的引线。那么如何促进学生的思维发 Concept formation and concept assimilation are the two main ways students acquire concepts. “Factor and Multiplier” As a concept class, students obtain mainly through the concept of assimilation, that is to say, the learner directly presents the interdependencies of factors and multiples to the learner in a defined way. The learner reuses the original concept understanding in the cognitive structure This relationship. Therefore, such a concept class is easy for students to enter the “mimic dictation” cycle, lacking the lead that prompts students to spontaneously collide. So how to promote the thinking of students
