“说”在人们印象中,是语文、英语这类科目的事情。人们更多认为数学所强调的是思考、计算。因此很长一段时间以来,在数学教学中当学生对某一个概念不太明了的时候,或是不会解答时,教师常常是“有话说话”。这似乎也解决了学生的问题,但仔细分析,却发现未能从根本上解决问题。其原因就在了未能考虑学生对问题的思考性,直接进行提点,其指导不具有针对性。因此,为了可以更好拓展学生思维,“说”就变得更加重要。 “Say ” In people’s minds, it is a matter of language, English such subjects. People think mathematics emphasizes thinking and calculating more. So for a long time, in maths teaching, when a student is not quite sure about a particular concept, or when he or she can not answer it, the teacher is often “having something to say”. This seems to have solved the problems of the students as well, but after careful analysis, they found that they failed to solve the problems fundamentally. The reason lies in the failure to consider the student’s thinking on the issue, direct mention, the guidance is not targeted. Therefore, in order to better develop students’ thinking, “say ” becomes even more important.
