Hotspots and Trend Analysis of Comparative Research on Junior High School Mathematics Textbooks Based on CiteSpace

基于中国知网数据库，选取2004~2024年初中数学教材比较研究的文献作为研究对象，运用CiteSpace软件进行关键词共现网络、突现词检测和时区图谱的可视化分析，深入剖析该领域的研究热点分布、演进脉络及其在新课标背景下的发展趋势。研究发现该领域的研究历程随课程改革深化而呈现出阶段性特征，可划分为初步发展期(2004~2010)、平稳发展期(2011~2020)和快速增长期(2021~2024)三个阶段。主要结论为，近20年国内初中数学教材比较研究的主题丰富且聚焦，涵盖的关键词之间联系紧密，且集中度高；近年“跨学科”关键词作为突现性前沿热点凸显，这反映了在新课标强调学科融合的导向下，跨学科视角正成为教材比较研究的重要发展趋势。Based on the CNKI database, this paper selected documents on comparative research of junior high school mathematics textbooks from 2004 to 2024 as research objects. CiteSpace software was used to conduct a visualized analysis through keyword co-occurrence networks, burst word detection, and timeline maps. The study deeply analyzed the distribution of research hotspots, the evolutionary trajectory, and the development trends under the new curriculum standards in this field. The research reveals that the research process of this field has shown phased characteristics with the deepening of curriculum reform. It can be divided into three stages: the initial development stage (2004~2010), the steady development stage (2011~2020), and the rapid growth stage (2021~2024). Over the past 20 years, the themes of domestic junior high school mathematics textbook comparative research have been rich and focused. The keywords are closely related and highly concentrated. In recent years, the keyword “cross-disciplinary” has significantly emerged as a frontier hotspot. This reflects that under the guidance of the new curriculum standards emphasizing interdisciplinary integration, the cross-disciplinary perspective is becoming an important development trend in textbook comparative research.
