摘要
数学教材中的习题在数学教学中发挥着重要的作用,习题的难度在一定程度上反映了教材的难度,本文利用一个综合难度模型,选取中国、美国、新加坡三套初中数学教材中"三角形有关的角"的内容,从习题的背景、数学认知、运算、推理、知识综合五个因素进行分析,为我国初中数学教材编写提供参考。
The problem sets in mathematics textbooks play a multi-functional role in mathematics teaching and learning and the difficulty of problem sets affects the difficulty of mathematics textbooks. With three sets of junior school mathematics textbooks from China Singapore and the United States about the angle of triangle the present paper uses a composite difficulty model to analyze the difficulty levels of problem sets in the textbooks with respect to 5 factors—the problem context the mathe？matical cognition the computation complexity the reasoning difficulty and the topic coverage of the angle of triangle.It may pro？vide references for the compilation of junior school mathematics textbooks in our country.
