客观事物之间的联系是普遍存在的,各种矛盾无不在一定的条件下相互转化。事物之间的转化,反映在数学上就是转化思想,又称化归思想。在数学教学中,运用“符号思想、函数与方程思想、数形结合思想、分类思想”等数学思想方法去分析解决问题,其目的是完成复杂向简单、抽象向直观、困难向容易、陌生向熟悉、未知向已知的转化。因此,转化思想是数学思想的核心。在教学中,始终紧扣“转化”
The connection between objective things is ubiquitous, and all kinds of contradictions are mutually transformed under certain conditions. The transformation between things, reflected in mathematics is the transformation of ideas, also known as the return to thought. In mathematics teaching, we use the mathematical thinking methods of “symbolic thought, function and equation thought, numerical conjunctive ideation and classification ideation” to analyze and solve the problem. The purpose is to complete the process from complex to simple, abstract to intuitive, difficult to easy, Unfamiliar to the familiar, unknown to the known transformation. Therefore, transformation thinking is the core of mathematical thought. In teaching, always close “conversion ”
