2017~2022年国内中小学数学学科大概念研究的回顾与展望

Review and prospect of research on big concept of mathematics subject in primary and s secondary schools in China from 2017 to 2022

为明晰《普通高中数学课程标准(2017年版)》提出学科大概念以来,国内数学学科大概念的研究情况,以中国知网数据库中的348篇数学学科大概念文献作为研究对象,使用CiteSpace5.8.R3软件绘制知识图谱,结合文献计量法与共词分析法,对所选文献作定量和定性分析.研究发现,目前国内数学学科大概念研究存在以下共性问题:数学学科大概念的定义模糊,概念提取还存在难度;单元教学设计需考虑的因素较多,研究梳理不够,未形成系统;教学实践经验不足,缺少优秀的师资队伍.对此提出一些建议:加强跨区域合作,清晰概念定义,解决提取困难;梳理单元教学设计的研究成果,并形成系统;提高教师素养,打造良好的师资队伍.

In order to clarify the research situation of big concept of mathematics subject in China since it was put forward in the Mathematics Curriculum Standards for Senior High Schools.(2017 Edition),348 literatures on big concept of mathematics subject in the database of China National K nowledge Network were taken as research objects.The knowledge graphs were drawn by using CiteSpace5.8.R3 software,and the quantitative and qualitative analysis of the selected literature was made,com bined with the bibliometric method and co-word analysis.The research showed that there were the following common problems in the study of big concept of mathemat-ics in China:the definition of big concept of mathematics was fuzzy,and it was difficult to extract the concept;there were many factors to be considered in unit teaching design,yet the research and sorting were inadequate,and no system had been formed;teaching practice experience was insufficient and lack of excellent teaching staff.For this,some suggestions were put forward to strengthen the cross regional cooperation,clarify the definition of concept,and solve the difficul-ty of extraction;sort out the research results of unit teaching design and form a system;improve the quality of teachers and build a good team of the teachers.
