在初中数学教学中,教师要根据教学内容和学生实际,精心设计适当的问题情境,促进学生新旧知识认知冲突的形成,在思维碰撞中形成对知识的构建.那么,在教学中应该如何巧妙设计问题以提高课堂效率呢?下面笔者结合自己的教学实践,从教师在问题设计中出现的弊端说起,谈谈自己对问题设计的认识,并提出优化设计的几个原则.一、问题设计中常见的几种现象1、问题情境不恰当情境教学以它生动活泼的形式,易于引
In junior high school mathematics teaching, teachers should carefully design appropriate problem situations according to the teaching content and students’ actual conditions, promote the formation of cognitive conflict between new and old knowledge of students, and form the knowledge construction in the collision of thinking.Then, how to be clever in teaching Design problems in order to improve the efficiency of the classroom? Here I combine my own teaching practice, from the teachers in the problem design problems, talk about their own understanding of the problem design, and put forward several principles of optimal design. Several common phenomenon in 1, the problem situation is not appropriate to situational teaching in its lively form, easy to lead
