概念课就是让学生通过一定的学习活动,在反复的实践和认知过程中,将事物共同体的本质特点抽象出来加以概括,从感性认识上升到理性认识,从而形成概念的一种课型。显然,从直观到抽象,从感性到理性,对于中学生来说,是非常困难的。通过几年来对初中数学的教学,我对数学知识各个环节的教学方法有了较深刻的认识。其中基础知识的教学是最重要的一个环节,而概念的教学又是学好基础知识的前提。大多数在数学方面学习较差的学生首先是因为对概念不理解而造成的。可以这
Concept lesson is to let students through certain learning activities, in the process of repeated practice and cognition, abstract the essence of things community out to be summarized from the perceptual awareness to rational understanding, thus forming a concept of a course. Obviously, from intuition to abstraction, from sensibility to rationality, it is very difficult for middle school students. After several years of junior high school mathematics teaching, I have a deeper understanding of the teaching methods of all aspects of mathematical knowledge. The teaching of basic knowledge is the most important link, and the teaching of concept is the premise of learning basic knowledge. Most students who study poorly in mathematics are primarily those who fail to understand concepts. Can this be
