王荣今同志的这篇文章值得一读。小学数学课本里的内容,虽然很简单,但要把它(包括编排意图)真正弄明白、搞清楚,并不是很容易的。如果没有吃透教材、充分了解学生就匆忙地考虑教学的形式和方法,难免“方底圆盖”不能相合。所以备课首先要注意分析教材,领会编排意图,才能针对学生实际有效地进行教学。 Comrade Wang Rongjin's article is worth reading. Primary school mathematics textbooks, although very simple, but it (including the layout intent) really understand, find out, not easy. If you do not digest the teaching material, fully understand the students to consider the form and method of teaching in a hurry, it is inevitable “square cover” can not match. Therefore, the preparation of the lesson must first pay attention to the analysis of teaching materials, understand the layout intent, in order to effectively deal with the teaching of students.
