一堂课也要有思想方法上的主题 ,而且这主题要较自然的蕴涵、渗透在课的展开之中 .每堂数学课 ,只有题型与训练 ,从头到尾 ,内容充斥得满满的 ,把重要的数学思想方法一概视而不见的做法 ,越来越受到人们的非议 :这样的课 ,还有重要方面需改进 !然而 ,一堂课 ,每讲一道题 ,末了总是去贴上一个个标签 :这是运用方程思想 ;那是逆向思维 ;…只是这样做 ,效果也不会好 ,学生只多听到了一个个名词 ,许多人还不知其所云呢 .每堂课涉及的数学思想方法 ,不是都要去揭示 ,不是揭示了就多多益善 .根据内容的特点与需要 ,在一堂课上 ,重点突出一两个就可以了 .凡所注目的 ,结合内容的展开 ,适度地作点说明 ,主要是要渗透与蕴涵在整堂课的过程之中 .比如 ,这一课的思想方法上的主题就是 :化归与理解 .
There must also be a theme of thought in a class, and this theme should be more natural than the implication and penetration in the development of the class. Each class of mathematics, only the questions and training, from beginning to end, full of content, The practice of disregarding important mathematical thoughts and methods is getting more and more criticized by people: There are still important aspects that need to be improved! However, for each lesson, one lesson is always affixed with a label: This is the use of equations thinking; that is reverse thinking; ... just to do so, the effect will not be good, students only heard one by one, many people still do not know what they are. The mathematical thinking methods involved in each class, not To reveal, instead of revealing, we need to be better. According to the characteristics and needs of the content, we can focus on one or two highlights in a class. Where the attention is focused on, the contents should be appropriately explained. It is necessary to penetrate and implication in the process of the whole class. For example, the theme of this lesson’s ideology and method is: transformation and understanding.
