基础复习教学,要重视运算能力的培养。《义务教育数学课程标准》(2011年版)(以下简称《课标》(2011年版))明确指出: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。数学运算既是基本技能,也是思考和解决问题的基本工具,还是一种核心数学能力~([1])。现笔者以“实数复习”一课为例,与各位同行分享交流如何在教学中培养学生的运算能力。1教学分析1.1考点分析本章是学习二次根式、一元二次方程的预备知
Basic review of teaching, should pay attention to the cultivation of computing power. Compulsory Education Mathematics Curriculum Standard (2011 Edition) (hereinafter referred to as “Curriculum Standard” (2011 Edition)) clearly states that computing power mainly refers to the ability to operate correctly according to the law and computing laws. The ability to cultivate computing power helps students understand the arithmetic of computing and seek a reasonable and concise way to solve the problem. Mathematical computing is both a basic skill, a basic tool for thinking and solving problems, or a core mathematical ability ~ ([1]). Now I “real number review ” lesson, for example, to share with colleagues how to train students in the teaching of computing power. A teaching analysis 1.1 test point analysis This chapter is to learn the secondary root, a quadratic equation of the prepared know
