数学概念是事物在数量关系和空间形式方面的本质属性,是人们通过实践,从数学研究对象的许多属性中,抽出其本质属性概括而形成的。它是进行数学推理、判断的依据,是建立数学定理、法则、公式的基础,也是形成数学思想方法的出发点。人教版《数学》八年级上册《一次函数》第一节“变量与函数”就是一节概念课课型。函数是数学中最重要的基本概念之一,它揭示了现实世界中数量关系之间相互依存和变化的实质,是刻画和研究现实世界变化规律的重要模型,是初中数学函数入门。如何让枯燥的概念课生动有趣呢?我们一起来欣赏
Mathematic concepts are the essential attributes of things in terms of quantity relations and spatial forms. They are formed through the practice of extracting the essential attributes from many attributes of mathematical research objects. It is the basis for mathematical reasoning and judgment. It is the basis for establishing mathematical theorems, rules and formulas, and is also the starting point for forming mathematical thinking and methods. PEP “math” eighth grade on the book “a function” section “variables and functions ” is a concept course class. Function is one of the most important basic concepts in mathematics. It reveals the essence of the interdependence and change between the quantitative relations in the real world. It is an important model to describe and study the changing law of the real world, and is the introduction of the mathematical function of junior high school. How to make boring concept lesson lively and interesting? Let’s enjoy together
