数学教学中教师既要讲清楚这道题“应该怎样做”更要讲清楚“为什么要这样做”“应该这样做”这是教师采用综合叙述方法从题目开始一步一步推理一次一次计算解证例题也就是教师利用逻辑的力量使学生信服。如果教学仅止于此只完成了一半教学任务。教师还应该站在学生的角度从学 In mathematics teaching, teachers need to make it clear that this question should be “how to do it.” It is even more necessary to make it clear “why you should do this” and “should do this.” This is a teacher’s use of a comprehensive narrative method to start from step-by-step reasoning once and for all.
