在数学学习过程中,很多学生对复杂的运算叫苦不迭.学生对数学的厌烦,多数缘于运算的过于繁琐,但运算又是进行数学研究的必要手段和必经之路,运算能力是数学基本能力之一,是高考考察的一个重要方面,所以如何提高学生的运算能力一直是广大师生关心的重要问题.《上海市中小学数学课程标准》中关于运算能力这样指出:理解算理,能够根据问题条件,寻找与设计合理、简洁的运算途径,通过运算进行推理探求.这一方面说明了运算能力的重要性,另一方面也说明了造成复杂运算的原因并不是问题本身的复杂,而是没有找到合理的途径.以下是笔者在教学实践过程中摸索出的关于如何能减少运算的几点看法,旨在改变部分学生的运算观,提高他们的运算能力,期指正.
In the process of mathematics learning, many students complain about complex computing.The students are tired of mathematics, mostly due to the operation is too complicated, but arithmetic is necessary means and must pass through mathematics research, computing power is basic mathematics Ability is one of the important aspects of college entrance examination, so how to improve the computing power of students has always been an important issue of concern to teachers and students.Shanghai primary and secondary math curriculum standards on the computing power that: to understand the arithmetic, to According to the conditions of the problem, looking for and designing a reasonable, concise way of computing, through the operation of reasoning to explore.This one illustrates the importance of computing power, on the other hand also shows that the cause of complex computing is not the complexity of the problem itself, and Is not found a reasonable way.The following is the author in the teaching practice in the process of exploring how to reduce the operation of a few views, aims to change some students view the operation, improve their computing power, correct the period.
