数学课堂教学离不开对问题的探求,老师们也不例外.常用发现问题、提出问题、分析问题、解决问题之所谓“四轮驱动”问题研究的方法,进行课堂教学.试想,如果最后归结为一个前人尚未提及的全新的数学问题,则可为学生树立一个榜样,从而增进他们的学习兴趣.现按上述问题研究的思路,对“平移和轴对称这两种变换在什么情况下是等价的”这一问题,试行深入 The teaching of mathematics can not be separated from the question, the teachers are no exception.It is often used to find the problem, put forward the problem, analyze the problem, solve the problem of the so-called “four-wheel drive And finally comes down to a new math problem that has not been mentioned by the predecessors, which can set an example for students to enhance their interest in learning.According to the above problems, the two translations of ”translation and axisymmetry Under what circumstances is the equivalent of "this issue, pilot depth
