高中数学教材中的比较研究——以直线的倾斜角与斜率为例
A Comparative Study in High School Mathematics Textbooks—Taking the Inclination Angle and Slope of a Straight Line as Examples

教材是知识传承的关键载体，其内容与结构、知识呈现形式对教学成效至关重要。文章通过深入对比人教版高中新旧教材，从内容结构与知识呈现两大维度出发，为教学设计的更新提供有益参考。在内容结构方面包括内容选择、学习要求以及编排顺序，在知识呈现方面，包括章节引言、概念生成、栏目设置以及信息技术的对比分析。根据结论得到以下教学建议：教师应聚焦教学重点变革教学理念，遵循规律激发学生兴趣；注重教学内容与数学史相结合，凸显立德树人的教育功能；强化教学预设提问与作业设计，助力学生成长与发展；教学内容与信息技术深度融合，开启现代化教学新篇章。
Textbooks are the key carriers of knowledge inheritance, and their content and structure, as well as the forms of knowledge presentation, are crucial to the effectiveness of teaching. This research delves deeply into the comparison between the old and new high school textbooks published by the People’s Education Press. Starting from the two major dimensions of content structure and knowledge presentation, it provides valuable references for the updating of instructional design. In terms of content structure, it encompasses elements like the selection of content, learning requirements, and the order of arrangement. When it comes to knowledge presentation, it involves a detailed comparative analysis of chapter introductions, the generation of concepts, the setup of columns, and information technology. Based on the conclusions drawn from this comparison, several practical teaching suggestions are put forward. Firstly, teachers should zero in on the key points of teaching and transform their teaching concepts accordingly. They must follow the educational rules to arouse students’ interest. Secondly, attaching importance to combining teaching content with the history of mathematics can effectively highlight the educational function of cultivating students’ moral character and achieving the goal of nurturing them into individuals with integrity. Thirdly, strengthening the design of preset questions in teaching and the layout of homework can better assist students in their growth and development. Finally, integrating teaching content with information technology in a profound way will open a brand-new chapter in modern teaching.
