数学概念是对客观事物的数量关系、空间形式或结构关系的特征概括,是对一类数学对象的本质属性的真实反映。数学概念的教学既是数学教学的关键环节,又是数学学习的核心所在。因此概念教学在数学课堂教学中起到举足轻重的作用。那么如何进行有效的数学概念教学呢?下面我就结合自己的教学实践谈谈看法。一、数学概念的合理引入1.从数学本身发展需要引入概念。从数学内在需要引入概念是引入数学概念的常用方法之一,这样的例子随处
The concept of mathematics is a summary of the quantitative relations of objective things, the spatial forms or the structural relations, which is a true reflection of the essential attributes of a class of mathematical objects. The teaching of mathematical concepts is not only the key link of mathematics teaching, but also the core of mathematics learning. Therefore, concept teaching plays a decisive role in mathematics classroom teaching. So how to carry out effective teaching of mathematical concepts? Now I will talk about their own teaching practice. First, the rational introduction of mathematical concepts 1. The development of mathematics itself requires the introduction of concepts. The introduction of concepts from the internal needs of mathematics is one of the commonly used methods to introduce mathematical concepts, examples of which are everywhere
