在高三数学复习教学中,我们可以选取课本上较为典型的例题,对题目深入探究并作出变式与猜想,这有利于引导学生主动参与课堂教学活动,有利于揭示知识间的联系、开阔解题思想,从而提高学生的学习效率.本文以人教A版《数学》选修1-1第39页例3为例,谈谈自己在高三数学复习教学中的具体做法.一、题目例题如图1,设点A,B的坐标分别为(-5,0),(5,0).直线AM,BM相交于点同M,
In the senior high school mathematics review teaching, we can choose the typical example of the textbook, explore the topic in depth and make the variations and conjectures, which is conducive to guide students to take the initiative to participate in classroom teaching activities, is conducive to reveal the connection between knowledge and open problem solving Thinking, so as to improve the learning efficiency of students.This paper takes People’s Education A version of “Mathematics” Elective 1-1 Example 39 as an example, to talk about their own practice in the third year of mathematics review teaching. , Set the coordinates of points A, B were (-5,0), (5,0). The straight line AM, BM intersect at the same point M,
