我国基础教育一直将数学运算作为主要内容,《数学课程标准(2011年版)》指出:“运算能力主要是指能够根据法则和运算律正确地进行运算的能力。培养运算能力有助于学生理解运算的算理,寻求合理简洁的运算途径解决问题。”那么,数学运算是否等同于运算技能?学生除了掌握基本的运算技能外,还有哪些有“价值”的学习内容?本文认为运算的本质是映射,通过特定的探究活动,让学生感悟算理和算法。因而,数学运算应以思维为主线、以算理为先导、 The basic education in our country has been regarded as the main content of mathematics, “Mathematical Curriculum Standard (2011 Edition)” pointed out: “computing power mainly refers to the ability to operate correctly according to the law and computing law .Calculate computing power helps students to understand Computing algorithm, to find a reasonable and concise way to solve the problem. ”So, is the mathematical equivalent of computing skills? Students in addition to master the basic computing skills, what else? " Value The essence of computation is mapping, which enables students to comprehend arithmetic and algorithms through specific inquiry activities. Therefore, mathematical operations should take the thinking as the main line, take the calculation as the guide,
