初中数学的运算,主要包括数和式的变形和运算,初等超越运算和简单的数据统计和处理,几何图形的边长、角度以及面积的有关运算。因此,运算能力在初中指的就是准确、合理和敏捷的完成上述运算的能力。完成运算具体表现为在定义、性质、运算律的指导下对数、式、几何图形进行组合与分解变形。一般地,培养学生的运算能力有以下途径。1正确理解和掌握数学基础知识培养和提高学生运算能力的根本途径是使学生正确理解和掌握数学的概念、性质、公式和法则等基础知识.培养和提高学生运算能力的根本途径是使学生正确理解和掌握数学的概念、性质、公式和法则等基础知识。新教材的编写,更突出了这些要
The arithmetic of junior middle school mathematics mainly includes number and type of deformation and operation, primary overrun operation and simple data statistics and processing, geometry side length, angle and area related operations. Therefore, computing power in junior high school refers to the ability to complete the above operations accurately, reasonably and quickly. Completion of the operation is specifically manifested in the definition, nature, arithmetic law under the guidance of logarithm, type, geometry, combination and decomposition deformation. Generally speaking, there are following ways to develop students’ computing abilities. A Correct Understanding and Grasping the Basics of Mathematics The fundamental way to cultivate and improve students ’computing abilities is to enable students to correctly understand and master the basic concepts of mathematics such as the concept, nature, formulas and rules, etc. The fundamental way to train and improve students’ computing abilities is to make students correct Understand and master the basic concepts of mathematics, such as the concept, nature, formula and law. The preparation of new textbooks, more prominent these needs
