“提问一答问”是教学中最基本、最常规的形式,但是我们常常发现有这样的问题,一些教师重问轻答,或越俎代庖,或蜻蜒点水,对学生的回答或不可置否,或不予点拨,这严重地影响了教学效果。其实,问是开启思路,答是问的延伸,是思维成果的展示,问得妙,答得恰到好处,才是高质量的训练,因此,为了更好地使“问”和“答”这两个环节相互促动,把教学提高到一个更高的境界,我们要高度重视答问的指导。铺垫“问”的背景。教学中,不做好背景铺垫,仓促提问,要学生来答,这是强人所难。比如,要学生指出“下列哪些语句可以确定集合”就得先将清楚集合的确定性;要学生判断函数y=的奇偶性,就得先讲清奇、偶函数的定义或在数轴上表示时关 “Questions and Answers” is the most basic and the most common form of teaching.

In fact, the question is to open the train of thought, answer is an extension of the question, is the demonstration of the result of thinking, ask well, answer just right, is the high quality of training, therefore, in order to better make “question” and “answer ”These two links promote each other, the teaching to a higher level, we should attach great importance to the guidance of the question and answer. Mat bedding “ask ” background. Teaching, do not pave the way for the background, hastily asked questions, to students to answer, this is a strong man hard. For example, students should be pointed out that “the following statement can determine the set,” you must first understand the certainty of the collection; to determine the parity function y =, we must first talk about the definition of odd or even function on the number of axes Express off
