三版初中数学教材“一元一次方程”内容的比较研究
A Comparative Study on the Content of “Linear Equation with One Unknown” in the Three Editions of Junior High School Mathematics Textbooks

初中数学教材的内容编排对于教学的质量和效果起着至关重要的影响。它不仅是教学活动的基础和保障，也是学生获取数学知识的主要来源。因此，需重视教材的编写和使用，此次研究通过人教版、苏科版、北师大版这三版教材的“一元一次方程”的内容编排方式为研究对象，从章前页、章节、知识点的呈现方式、数学史、课后习题这五个维度进行比较研究，分析三版教材内容的异同点，并提出对教材编排的一些建议。
The content arrangement of middle school mathematics textbooks plays a crucial role in the quality and effectiveness of teaching. It is not only the foundation and guarantee of teaching activities, but also the main source for students to acquire mathematical knowledge. Therefore, it is necessary to pay attention to the writing and use of textbooks. This study focuses on the content arrangement of the “linear equation with one unknown” in the People’s Education Press, Suke Press, and Beijing Normal University Press. A comparative study is conducted from five dimensions: chapter front page, chapter, presentation of knowledge points, mathematical history, and after-school exercises. The differences and similarities in the content of the three versions of textbooks are analyzed, and some suggestions for textbook arrangement are proposed.
