高中数学三版教材“复数”部分比较研究
A Comparative Study of the “Plural” Part of the Three Versions of the High School Mathematics Textbook

教材研究与建设一直是课程与教学研究中的核心问题，是教学质量提升和教学改革实施的基本保障。近年来，对数学教材进行比较研究已经在数学领域成为了一个热门话题。通过对比不同版本教材的数学知识，可以帮助教师厘清知识脉络，了解知识点之间的关联，并且可以帮助学生更好地系统掌握数学知识。选取“人教A版(2019年版)”、“苏教版(2019年版)”和北师大版(2019年版)为研究对象，以复数章节为例，利用内容分析法对三版教材进行比较研究，发现人教A版教材更注重知识间的关联性，苏教版教材更注重习题的设置，北师大版教材更注重知识的探究。并提出合理分配习题、培养自主探究能力、加强数学史和数学文化的渗透三条建议，以便更好服务教育教学。
The research and construction of teaching materials has always been the core issue in curriculum and teaching research, and is the basic guarantee for the improvement of teaching quality and the implementation of teaching reform. In recent years, comparative research on mathematics textbooks has become a hot topic in the field of mathematics. By comparing the mathematical knowledge of different versions of the textbook, it can help teachers clarify the knowledge context, understand the relationship between knowledge points, and help students better grasp mathematical knowledge systematically. Taking “Renjiao A Edition (2019 Edition)”, “Jiangsu Teaching Edition (2019 Edition)” and Beijing Normal University Edition (2019 Edition) as the research objects, taking the plural chapters as an example, the content analysis method was used to compare and study the three versions of the textbook, and it was found that the A textbook of Renjiao paid more attention to the correlation between knowledge, the Jiangsu Teaching Edition textbook paid more attention to the setting of exercises, and the Beijing Normal University textbook paid more attention to the exploration of knowledge. It also puts forward three suggestions: reasonable allocation of exercises, cultivation of independent inquiry ability, and strengthening the penetration of mathematical history and mathematical culture, so as to better serve education and teaching.
