化归是把待解决的问题通过某种转化过程归结为一类已经解决或比较容易解决的问题,是中学数学最基本的思想方法.其核心就是将有待解决的问题转化为已有明确解决程序的问题,以便利用已有的理论、技术来加以处理,从而培养学生用联系的、发展的、运动变化的观点观察事物,认识问题.下面以“概率”教学中运用化归思想为例说明.
It is the most basic thought and method of middle school mathematics that the problem to be solved is reduced to some sort of solved or relatively easy to solve through some transformation process.The core of the problem is to convert the problem to be solved into a clear solution to the problem In order to use the existing theory and technology to deal with, so as to cultivate students to use the contact, development, changes in the perspective of things to observe things, to understand the problem.
