基本结构单位”。正确的概念是科学抽象的结果,也是人们对客观事物的一种本质认识。正确理解数学概念是掌握好数学基础知识的前提,是命题推理和证明的基础,是解题的关键,所以,概念教学尤为重要。 一、从实例引人新概念 引入数学概念的感性材料是十分丰富的。教学中可通过学生日常生活中所接触到的事情、事物,也可通过教材中的实际问题以及模型、图形、图表等,
The basic structural unit.” The correct concept is the result of scientific abstraction, and it is also an essential understanding of objective things. Correct understanding of mathematical concepts is the prerequisite for mastering the basic knowledge of mathematics, is the foundation of propositional reasoning and proof, and is the solution to the problem. The key is, therefore, the concept of teaching is particularly important.I.Introducing the new concepts from the examples introduces the perceptual material of the mathematical concept is very rich.The teaching can be through the students in daily life in contact with the things, things, but also through the teaching materials Actual problems and models, graphs, charts, etc.
