在数学课例教学中,运用化归法的频率很高,可很多教师对化归法还存在一些模糊认识,导致课例教学生搬硬套,教学效果大打折扣。化归法的成功使用,可以将复杂的、深奥的、抽象的数学问题简单化、浅显化、具体化。课例教学化归法运用需要掌握一定的技巧和方法,要处理好化归法的选择、运用、拓展等技术环节。一、选择化归,注重内容契合度数学课例教学要成功引导学生思维进入数理环境之中,教师需要采取多种教学手段,找到学生认知和教
In the teaching of mathematics, the frequency of using the law of return is very high, but many teachers still have some vague understanding of the law of return, which leads to the teaching of the teaching of the course is cumbersome and the teaching effect is greatly reduced. The successful use of the law, can be complicated, esoteric, abstract mathematical problems simplistic, simple, specific. The teaching reform of the teaching of the course needs to master a certain amount of skills and methods, and should be handled properly in the selection, application and development of the law of return. First, the choice of return, pay attention to content fit Math class teaching to successfully guide students into the mathematical environment, teachers need to take a variety of teaching methods to find students cognitive and teaching
