不同版本教材知识点设置的比较研究——以初中数学平行四边形为例摘要 随着课程改革不断推进，各地出现了各有特点的数学教材,教材的编写者有不同的思路，因此教材在各个方面也会存在一定的差异，同时不同版本的教材对比也有助于教师更好地教学与进行教学研究.通过对人教版、北师大版、苏科版中的“平行四边形”部分进行比较研究,从而帮助对该部分知识点的全面把握,以便更好地把握数学教材内容,优化教学设计.通过文献分析法、对比分析法、统计法、问卷调查法对不同版本初中数学教材从结构 、引入、探究及习题设置进行了比较，从而发现三个版本教材的特色以及各自的异同点.通过对此课题的研究,提供一些有益的数学教学建议.关键词 平行四边形 教材对比 人教版 北师大版 苏科版 A comparative study on the set of knowledge points in different editions of textbooks I—— A case study of Parallelogram in junior middle schoolAbstract With the continuous advancement of the curriculum reform, mathematics textbooks with their own characteristics have appeared in various places. The compilers of the textbooks have different ideas, so there are certain differences in various aspects of the textbooks, at the same time, the comparison of different versions of teaching materials is helpful to teachers. This paper makes a comparative study of the "Parallelogram" section in the people s education press, the Beijing Normal University press and the Soviet section press, so as to help us grasp the knowledge points of this section in an all-round way, so as to better grasp the contents of the mathematics teaching materials and optimize the teaching design. Through literature analysis, Comparative Analysis, Statistics and Questionnaire survey, this paper compares the structure, Introduction, exploration and problem setting of different editions of junior middle school mathematics textbooks, thus discovered three edition teaching material's characteristic as well as...
