初中数学教材中有理数的内容分析研究

Content Analysis of Rational Number in Junior High School Mathematics Textbooks

教材研究是教育改革的重要保障,既有利于课程开发,也有利于数学教师加深对数学教材的理解。运用内容分析法从数学思想、文本结构、例题习题和概念命题的呈现方式这四个方面对人教版和北师大版教材中有理数内容进行比较研究。研究发现,人教版教材注重掌握新知后的能力提升,北师大版偏向于新知与扩展相结合。研究结果可为初中数学有理数内容的编写和教学设计提供参考。

Research on teaching materials is an important guarantee for educational reform.It is conducive not onlyto the development of the curriculum,but also to teachers of mathematics to deepen their understanding of mathematicstextbooks.The content analysis method is used to compare the rational number content in the PEP and the BNUP fromthe four aspects of mathematics thinking,text structure,example problems and presentation of concept propositions.Thestudy found that the PEP pays attention to the improvement of the ability of mastering the new knowledge.The BNUPtends to combine the new knowledge with the expansion.The research results can provide reference for the compilationand teaching design of rational numbers in junior high school mathematics.
