问题变式：中国数学教材问题设计之特色

摘要

This study tried to uncover an important feature of problem design, one problem multiple changes （solutions） by comparing of the problem organization in the typical textbooks in the topic of fraction division between US and CHINA, which aims to make connections between concepts. This kind of strategy with problem variation reflects both advantage and disadvantage in Chinese curriculum design.%按问题变式（＂一题多变＂与＂一题多解＂）角度分类,中美教材分数除（乘）法内容比较揭示了中国教材较为鲜明的本土特色,中国数学教材＂分数除法＂的问题组织,比美国教材更注重利用＂一题多变＂（一个问题包含多个概念之变式的问题组织）与＂一题多解＂（一个问题包含多个解法之问题组织）,加强新旧概念连接,而美国教材的问题组织极少强调概念连接.问题变式,强调对比变化呈现差异,揭示了中国数学教材设计的特色.
