随着素质教育改革的不断深化,学生主体作用的发挥越来越重要。长久以来,由于受应试教育的影响,出现了重数学题的逻辑推理,忽视计算能力的培养,特别是数据偏大,计算麻烦的题目,多数学生只弄清步骤,不下功夫追求一个准确结果。这样,久而久之,学生的重要能力——计算能力,也就难以培养起来。《中学数学课程标准》要求:“中学数学教学的目的是:使学生学好从事社会主义现代化科学技术所必需的数学基础知识和基本技能,培养学生的运算能力,逻辑思维能力
With the continuous deepening of the reform of quality education, the role of students plays an increasingly important role. For a long time, due to the impact of exam-oriented education, there has been a logical reasoning of heavy math problems, neglecting the development of computational ability, especially the problem of too big data and calculating troubles. Most students only clarify the steps and do not devote themselves to pursuing an accurate result. In this way, over time, students’ important ability - computing power, it is difficult to cultivate. The standard of secondary mathematics curriculum requires: ”The purpose of middle school mathematics teaching is to enable students to learn the basic knowledge of mathematics and basic skills necessary for engaging in modern science and technology of science and education, develop students’ computing power and logical thinking ability
