郭思乐教授指出,我们把下定义、找结论、想方法的终结,称为课堂上的判断.课堂改革的措施之一,就是适当推迟判断,使学生有机会参与下定义、找结论、想方法的思维过程.因此,推迟判断是一种教学智慧.那么,如何做到推迟判断呢?笔者在“三角形内角和定理”一节课上,尝试采用推迟判断,效果出人意料,在此与大家分享.教师:大家是否知道,三角形的内角和是多少度?生1:等于180°.师:好,今天我们来研究一下,三角形的
Professor Guo Sole pointed out that we define the end of the definition, find the conclusion, think of the method as a classroom judgment.One of the measures in the classroom reform is to postpone judgments appropriately, so that students have the opportunity to participate in the definition, to find conclusions, think of ways Therefore, to delay the judgment is a kind of teaching wisdom.Then, how to delay judgment? The author in the “triangle interior angle and theorem ” a class, try to use delayed judgment, the effect is unexpected, here to share with you Teacher: Do you know how many degrees the interior angle of the triangle is? Health 1: equal to 180 °. Teacher: Well, today we will study the triangle
