初中数学教材习题的比较研究——以北师版与苏科版“勾股定理”章节为例

A Comparative Study of Exercises in Junior Middle School Mathematics Textbooks—The Chapter “Pythagorean Theorem” in the BNUP and the JPSP as an Example

本文从习题的数量、类型、背景水平以及数学认知水平4个方面,对北师版与苏科版初中数学教材中勾股定理的习题进行了比较研究。结果显示两版本教材在习题的数量上有一定的差异;在习题类型上基本相同;习题背景水平方面,两版本教材都以无实际背景的习题为主;在习题数学认知水平方面,苏科版教材主要以基础计算习题为主,北师版教材更加关注习题的探究与分析。

This paper makes a comparative study on the Pythagorean theorem exercises in the junior middle school mathematics textbooks of BNUP and JPSP from four aspects of the number, type, background level and mathematical cognitive level of the exercises. The results show that there are some differences in the number of exercises between the two textbooks. The types of exercises are basically the same;In terms of exercise background level, the two textbooks mainly focus on exercises without actual background;In terms of the cognitive level of exercise mathematics, the JPSP mainly focus on basic calculation exercises, while the BNUP pay more attention to the exploration and analysis of exercises.
