在中学阶段,数学与语文、外语一样是工具学科,因此,数学在各门学科中占有重要地位。但是,数学又与语文、外语不同,在解决数学题的过程中不仅需要学生具有形象思维能力,更需要学生具有抽象思维能力和推理运算能力,会将繁杂的解题过程进行转化。转化方法是高中阶段的重要数学思维方法。下面,笔者结合教学实践,就高中数学解题过程中常用的几种转化方法进行简明扼要的分析,与读者交流。1一般与特殊的转化辩证唯物主义告诉我们,普遍性(一般性)寓于特
In secondary school, mathematics is the same as language and foreign language. Therefore, mathematics occupies an important position in all disciplines. However, mathematics is different from Chinese and foreign languages. In the course of solving math problems, math requires not only students to have the ability of image thinking but also to have abilities of abstract thinking and reasoning, which will transform complicated problem-solving process. The conversion method is an important mathematical thinking method in high school. The following, the author combines teaching practice, high school mathematics problem solving process commonly used in several conversion methods for a concise analysis, and readers exchange. 1 General and Special Transformations Dialectical materialism tells us that universality (general)
