摘要
现行小学数学教科书中,关于"倍"及"倍数"的教学存在两方面的缺陷:首先是某些章节的描述有错误,再就是有意无意地回避对"倍"这样一个非常抽象的概念下定义,针对这两个弊端,笔者提出具体修改的意见:"扩大若干倍"要慎用,"缩小若干倍"应摒除。
The use of 'time' in primary school textbooks sometimes have many confusion even errors.For example,decrease 10 times etc.It occurs because there are some questions in the field of theory.The solution is that 'increase some times 'should be serious as using,or 'decrease some times' must be cleared out from textbooks.
