比较法是通过人们的仔细观察,认真分析,从而发现事物之间的不同点与相同点,将事物之间的关系进行辨析,加深人们对不同事物间的理解,扩大对事物的认识。小学数学中有很多既相似又有区别的概念,容易引起学生混淆,老师应该运用比较法对学生加以引导,提高学生对所学知识的辨析能力。笔者主要从以下三个方面来运用比较法,提高学生的数学思维能力:迁移,自主探究;分类,区别联系;建构,联结成网。一、迁移,自主探究
The comparative law, through careful observation and careful analysis by people, discovers differences and similarities between things, discriminates the relations among things, deepens people’s understanding of different things and expands their understanding of things. There are many similarities and differences between primary school mathematics concepts, easily lead to confusion of students, teachers should use comparative law to guide students to improve students’ knowledge of discrimination ability. The author mainly uses the comparative method from the following three aspects to improve students’ mathematical thinking ability: migration, independent inquiry; classification, distinction between connections; construction, linking into a net. First, the migration, self-exploration
