一、弄清算理,以理定法任何一种计算方法,都是奠定在一定算理基础之上的,而算理又是以某一概念作为依据的。因此,要提高学生的计算能力,首先必须使学生扎实地掌握基础知识,真正理解相关的概念、法则和算理。在教学过程中,我们必须高度重视基础知识的教学,引导学生以理定法,正确计算,不仅要知其然,还要知其所以然。这样计算的提高才能有切实的保证。例如,在教学“整数 First, to understand the arithmetic, to determine any method of calculation, are laid on the basis of a certain arithmetic, and arithmetic is based on a concept as a basis. Therefore, to improve students’ computing ability, we must first enable students to master the basic knowledge and truly understand the related concepts, rules and arithmetic. In the teaching process, we must attach great importance to the teaching of basic knowledge, guide students to rational law, correct calculation, not only to know it, but also know why. Such an increase in calculation can be effectively guaranteed. For example, teaching ”integer
