小学数学概念教学,一般是从概念的具体例子开始的,教师在概念的形成和深化阶段,也是紧密结合例子进行的。因此,在概念教学中,教师选例的质量事关概念教学的成败。一、概念的引人,选例要典型概念的引入是概念教学的第一步。学生能否形成准确的概念,很大程度上取决于学生首次感知时所接触的新材料。第一次没有感知准确的事物,以后 Primary school mathematics concept teaching, usually from the concrete example of the concept of the beginning of the concept of the formation and deepening of teachers, is also closely integrated with examples. Therefore, in the concept of teaching, the quality of teacher selection concerns the success of concept teaching. First, the introduction of the concept, the introduction of a typical example of the concept is the concept of teaching the first step. Whether a student can form an accurate concept depends to a large extent on the new material the student first came across. The first time did not perceive the exact thing, after
