基于SEC模型的初中数学教材习题与课程标准的一致性研究——以人教版和北师大版的“方程与不等式”内容为例

Research on the consistency of,junior high school mathematics textbook exercises and curriculum standards based on SEC model:Taking the content of"equations and inequalities"in Beijing Normal University edition and People's Education edition as an example

采用SEC一致性分析模型,以人教版、北师大版初中数学教材中“方程与不等式”内容的习题和《义务教育数学课程标准(2022年版)》为研究对象进行一致性分析.研究发现:人教版和北师大版的“方程与不等式”习题与数学课程标准“方程与不等式”内容的一致性较弱;在内容主题上,两版教材习题关于“方程与不等式的相关性质”的题量都较少;在认知水平上,两版教材习题考查水平均高于课程标准的要求.基于此,建议教材习题编写过程中应加强教材习题与课程标准的一致性,以使教材习题与课程标准更加契合,精准把控方向,落实“双减”政策要求.

Using SEC consistency analysis model,the"equations and inequalities"exercises in junior high school mathematics text books of the People's Education edition and the Beijing Nor-mal University edition and the Mathematics Curriculum Standards for Com pulsory Education(2022 Edition)were taken as the research objects for consistency analysis.The results show that the"equation and inequality"exercises in the People's Education Press edition and Beijing Normal University edition are weakly consistent with the"equation and inequality"content in mathematics curriculum standards.In terms of content theme,the textbook exercises of the two editions have fewer questions about"the related properties of equations and inequalities";in terms of cognitive level,the examination level of the textbook exercises in each edition is higher than the require-ments of the curriculum standards.Based on this,it is recommended that the consistency be-tween textbook exercises and curriculum standards should be strengthened during the compilation of textbook exercises,so as to make the exercises more compatible with curriculum standards,thus accurately control the direction,and implement the policy requirements of"double reduc-tion".
