《义务教育数学课程标准(2011年版)》(以下简称《课标(2011版)》)认为:数学在形成人的理性思维、科学精神和促进个人智力发展的过程中发挥着独特的、不可替代的作用[1]。数学概念作为理性思维的基本形式,既是数学学习的基石,也是提高学生数学学习能力、培养数学核心素养的前提。因此,概念教学到底怎样才能让学生在深刻理解数学概念的基础上,灵活运用数学概念解决问题,始终是一个值得思考和研究的问题。下面就以《二元一次方程组(1)》的教学为例与同行分享笔者的粗浅思考。
Compulsory Education Mathematics Curriculum Standard (2011 Edition) (hereinafter referred to as the “Standard (2011 Edition)”) that: Mathematics in the formation of rational thinking, scientific spirit and to promote personal intellectual development in the process of playing a unique, irreplaceable The role of [1]. As the basic form of rational thinking, mathematical concepts are not only the cornerstone of mathematics learning, but also the premise of improving students’ ability to learn mathematics and cultivating the core qualities of mathematics. Therefore, the concept of teaching in the end how to enable students to understand the concept of mathematics, based on the flexible use of mathematical concepts to solve the problem is always a question worth considering and research. The following on the “Binary Equations (1)” teaching as an example with peers to share the author’s superficial thinking.
