摘要
以多边形的面积为例,主要从习题的数量、认知水平和难易程度3个方面对小学数学人民教育出版社和北师大版两版教材进行比较研究.其中,认知水平主要从计算、概念、领会和分析4个水平进行比较分析,难易程度主要运用了鲍建生教授的综合难度模型,从探究、背景、运算、推理和知识含量5个方面进行比较.研究结果发现,在多边形的面积这一部分内容上,两版教材在习题的数量、认知水平和难易程度3个方面都存在一定的差异,这对教材编写和教师教学都有很好的参考作用.
Taking the area of polygons as an example,two versions of elementary school math textbooks of People′s Education Press and Beijing Normal University Publishing House were compared from three aspects:the number of exercises,the level of cognition,and the degree of difficulty.The cognitive level is mainly compared from the four levels of calculation,concept,comprehension and analysis.The degree of difficulty is mainly based on professor Baojiansheng′s comprehensive difficulty model,and comparative research is conducted from five aspects:exploration,background,calculation,reasoning and knowledge content.The results of the study showed that in the area of polygons,there were certain differences between People′s Education Press and Beijing Normal University Publishing House in the number of exercises,the level of cognition,and the degree of difficulty.This has a very good reference function for textbook writing and teacher teaching.
