初中数学“相交线与平行线”教材比较分析——以人教版与湘教版为例
A Comparative Analysis of the Textbook “Intersecting Lines and Parallel Lines” in Junior Middle School Mathematics—Taking the Humanistic Edition and the Hunan Edition as Examples

“相交线与平行线”是图形与几何这一体系的基础知识，是初中数学第二章节所学的内容。它是图形与几何的延伸，也是整个几何体系中比较重要的基础知识。通过这章节的学习，让学生了解几何起点，知道点与线之间的位置关系。由于学生容易在学习中忽略各种平行关系与定义以及混淆相关平行线性质与定义等关系，造成知识掌握不牢固。本文通过对不同教材的对比分析来让教师能够找出不同教材之间的差异性，以便于让教师能够根据学生的个体发展与差异性来设计更好的教材方法让学生掌握知识，理清学生对图形与几何这一体系的知识框架。
“Intersecting lines and parallel lines” is the basic knowledge of the system of graphics and geometry, which is the content of the second chapter of junior high school mathematics. It is not only an extension of graphics and geometry, but also an important basic knowledge in the whole geometric system. Through the study of this chapter, let students understand the geometric starting point, know the position relationship between the point and the line. Because students tend to ignore all kinds of parallel relations and definitions and confuse the relationship between the nature and definition of the relevant parallel lines in learning, the knowledge is not firm. Through comparative analysis of different teaching materials, this paper enables teachers to find out the differences between different teaching materials, so that teachers can design better teaching materials according to students’ individual development and differences to let students master knowledge, and clarify students’ knowledge framework of the system of graphics and geometry.
