有理数的加减法运算是有理数运算的基础。本文采用了内容分析法，以人教版初中数学教材和苏教版初中数学教材为例，对“有理数加减法运算”的相关内容进行分析对比研究。研究发现：人教版教材与苏教版教材在有理数加减法运算内容的呈现方面均以问题为主线，重视知识的形成过程。
The addition and subtraction of rational numbers is the basis of rational number operations. This paper adopts the content analysis method to analyze and compare the relevant content of “addition and subtraction of rational numbers” by taking the PPE version of the junior high school mathematics textbook and the Jiangsu Education Press of the junior high school mathematics textbook as examples. The research found that both the teaching materials of the People’s Education Edition and the textbook of the Jiangsu Education Press are based on the problem in the presentation of the content of the addition and subtraction of rational numbers, and pay attention to the formation process of knowledge.
