初中数学教材“二元一次方程组”内容比较分析——以人教版、北师大版、苏教版为例
Comparative Analysis of Junior High School Mathematics Textbook “System of Quadratic Equations”—Taking the People’s Education Edition, the Beijing Normal Education Edition, and the Suzhou Education Edition as Examples

二元一次方程组在数学中占有着非常重要的地位和作用，同时作为数与代数领域里方程与不等式主题的知识点，揭示了数学中最基本的数量关系，作为一类应用广泛的数学工具。本文将通过文献研究法、比较研究法以及统计法，从内容和习题两个层面对三本教材进行比较分析，发现在章前页、内容编排、呈现方式和习题等方面中存在着相同点和不同点，整合三版教材的相同点和不同点，使三个版本都能作为教师的课堂教学有力支撑。
The system of quadratic equations occupies a very important position and role in mathematics, and as a knowledge point of the topic of equations and inequalities in the field of mathematics and algebra, it reveals the most basic quantitative relationships in mathematics, and serves as a kind of mathematical tool with a wide range of applications. In this paper, we will compare and analyze the three textbooks in terms of content and exercises through literature research, comparative research and statistics, and find out the similarities and differences in the pre-chapter page, content arrangement, presentation and exercises, etc., so as to integrate the similarities and differences of the three versions of the textbook, and to make all the three versions serve as a powerful support for teachers’ classroom teaching.
