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

方程是一种重要的描述现实世界的数学模型，在解决实际问题中是应用广泛的数学工具。本文对三版教材中的“一元一次方程”章节内容对比研究，发现“一元一次方程”一章的内容在章前页、内容编排、呈现方式、融入数学史数量和例题习题等方面存在异同点。本文的研究，主要是为教材的编写和一线教师的课堂教学提供参考。
Equation is an important mathematical model to describe the real world, and it is a widely used mathematical tool in solving practical problems. This paper makes a comparative study on the content of the chapter of “linear equation with one unknown” in the three editions of textbooks, and finds that the content of the chapter of “linear equation with one unknown” has similarities and differences in the front page of the chapter, content arrangement, presentation mode, the number of mathematical history and examples and exercises. The research of this paper is mainly to provide reference for the compilation of teaching materials and the classroom teaching of front-line teachers.
