摘要
人教版和苏教版教材为了达到用样本的数学特征可以估计总体的数字特征的编写意图,采取了不同的编写方式.从课程标准和历史发生发展的角度看,先介绍具有测量背景的数据处理问题,然后依次介绍能用平均数、中位数处理的社会科学或生命科学中的数据问题,能更好的实现教材的编写意图.知识的历史发展顺序符合学习心理的序进原则,参考知识的历史发展顺序编写教材能实现数学知识的序和学习心理的序的有机统一.
In order to reach the instruction purpose of using the numerical characteristics of the sample to estimate that of the population,the way of writing mathematics textbook adopted by People s Education Press was different from that of writing mathematics textbook adopted by Jiangsu Education Press,From the opinion of mathematics curriculum standards and the genesis and development of mean and median,in order to reach fully the intention of the author of mathematics textbook,data-processing problems with the b...
