摘要
本文对数学中化归的方法含义 ,化归的方法要素和核心作了一些理论探索 ,提出了化归的三条基本途径 :( 1 )向基本模型化归 ;( 2 )向特殊模型化归 ;( 3)向低层模型化归。并对化归方法作了教学实践尝试 ,从熟悉化、简单化、直观化入手提出了化归是一种重要的解决问题的方法。
This article unfolds discussion on the concept of and the theoretical approaches to the'mathematical transformation and classification'.The three approaches summed up here are:1 the basic mode,2 the special mode,and 3 the lower-level mode.Based on the author's teaching experience,it concludes that the mathematical transformation and classification can be a familiar,simple and direct approach to the solution of many maths problems.
