小学数学知识中蕴含较多的如比较、转化、类比、符号化等数学思想方法,在运用时都需要对知识的共同性和差异性进行辨析。对教学内容,如能时常从“异与同”的关系审视之、思辨之、处理之,则能有效地提升学生的思维能力,为他们的终生学习建起思维支柱。如何处理好“异与同”的关系,我从两个方面进行了思考实践。 Mathematical knowledge in primary schools contains more mathematical thinking methods such as comparison, transformation, analogy, symbolization, and so on. All of them need to discriminate the commonalities and differences of knowledge when they are used. If the content of teaching can often be examined from the relationship between the different and the same, the thinking and handling can effectively enhance the thinking ability of students and build up their thinking pillars for their lifelong learning. How to handle the relationship between “different and the same”, I think and practice from two aspects.
