摘要
为了研究中国初中数学教材内容编写情况,采用内容分析法对中国现行10个版本初中数学教材中“无理数”内容编写特点进行研究.结果表明:各个教材都有自身的理解,编写既有自己的特色,也有普遍一致性;所有的教材都注重无理数概念对无理数的判定;所有的教材注重将有理数的运算与运算法则迁移到无理数.建议教材编写应加强关注学生学习心理与发展特征,调整数学史料编排方式促使学生体会数学史发展过程,搭建知识之间的关联助力学生建构数学知识体系.
In order to study the content compilation of junior high school mathematics textbooks in China,the content analysis method is used to study the compilation characteristics of“irrational number”content in the current 10 versions of junior high school mathematics textbooks in China.The results show that each textbook has its own understanding,and the compilation has its own characteristics and general consistency.All textbooks focus on the concept of irrational numbers to the determination of irrational numbers;all textbooks focus on the transfer of operations and arithmetic rules of rational numbers to irrational numbers.It is suggested that the compilation of textbooks should pay more attention to students’learning psychology and development characteristics,adjust the arrangement of mathematical historical data to promote students to experience the development process of mathematical history,build the relationship between knowledge,and help students to construct a mathematical knowledge system.
