难度是评价教材质量、衡量教材是否造成学生学业负担过重的重要指标,对教材编写与修订、课程改革实施等都具有重要参考意义.然而,国内外几乎没有用建构模型的方式来定量刻画教材的难度.为构建小学数学教材难度模型,基于文献分析、专家访谈,编制了小学数学教材难度影响因素调查问卷,并采用探索性和验证性因子分析等统计方法分析调查数据,从九个核心影响因素,内容难度、例题难度和习题难度等三个维度构建了小学数学教材难度线性模型N=0.30C＋0.36W＋0.34E,初步验证了模型的有效性.

The degree of difficulty is the important indicator for evaluating the quality of teaching materials and judging whether the teaching materials bring heavy study burden to students. It has referential significance for compiling and revising mathematics teaching materials and implementing mathematics curriculum reform. However, there is very little research using model building to portray teaching materials＇ difficulty home and abroad. In order to build a model of teaching material＇s difficulty of elementary school mathematics, the researchers designed a questionnaire to survey the key factors affecting the difficulty of elementary school mathematics teaching materials based on the literature review and expert interviews. The researcher analyzed the data using such statistical methods as exploratory and confirmatory factor a- nalysis. A linear model of the degree of elementary mathematics teaching materials＇ difficulty N=0.30C＋ 0.36W＋0.34E was constructed with nine key affecting factors in three difficulty dimensions including the difficulty of content, worked examples and exercises. The validity of the model was preliminarily verified.
