摘要
“三角形”是我国初中数学课程中非常重要的内容之一．按已建立的课程难度定量模型和数学题综合难度模型，对3个版本的初中新教材中的“三角形”的课程难度和各章后的复习题难度进行定量分析和比较，表明：3个版本的初中新教材中的“三角形”课程难度与《课程标准》的吻合度较高，其中“浙教版”的课程难度最大，但是它的习题的综合难度并不是最大的；“华师大版”基本与《课程标准》相同，习题难度均在其他两版本之间；“人教版”的课程难度略低于《课程标准》，但是它的习题难度比较大．将复习题难度和教材正文难度相结合对比分析，能更加全面客观地把握教材难度，对各地区教材选用提供帮助．
＂Triangle＂ was a very important mathematics course content of junior middle school, utilized the quantitative model of difficulty of course and exercises composite, carry on comparison and analysis to the difficulty of ＂Triangle＂ course of three new editions textbooks. The results showed that： The three editions textbooks with the curriculum criterion are consistent. The edition of Zhejiang education is the most difficult, but the exercises are not so difficult. The edition of East China Normal University is most approach with the curriculum criterion and the difficulty of the exercises is in middle. The edition of People of education is slightly lower than the curriculum criterion, but the exercises are harder than others. It is more comprehensive to compare the difficulty of the course and exercises, it can help areas to adapt the textbook.
