笔者上的一堂“不等式的性质”高三复习课,感觉教学效果良好,下面把这节课的教学过程整理如下.1.题目:已知a>2,b>2,比较ab与a+b的大小,并给予证明.学生表现:1分钟之内,全班36名学生都猜测出了比较大小的结果——ab>a+b有的是赋值试验,有的是大胆猜测“积比和大”.2.学生探讨证明方法(老师巡视学生的解法,但不做点拔和指导). The author on the “” nature of “” high school review class, feeling good teaching effect, following the teaching process of this class are as follows.1. Title: Known a> 2, b> 2, ab and a + b size, and to give proof of student performance: within 1 minute, 36 students in the class all guess the results of a relatively large --ab> a + b some assignment test, some are boldly guess Students explore ways to prove (teachers patrol students’ solutions, but do not point and guide).
