在数学教学中,会涉及许多数学概念,几乎每节课都有关于数学概念的数学问题.数学概念是揭示现实世界空间形式与数量关系本质性的思维形式.它是进行数学推理、判断、证明的依据,是数学思想和方法的载体.这些概念是学生在学习中正确思考问题的基础,使学生有创见地解决问题.它既是数学教学的重要环节,又是数学学习的核心.一、重视引入概念一个概念在学生的记忆中形成是具有一定过程的,教师在教学过程中应从具体到抽象,从现象到本质.引导学生也要从现象到本质逐步形成概念,而运用直观对比的方法往往比单纯、孤立地讲授概念效果
In mathematics teaching, there are many mathematical concepts involved, and almost every lesson has mathematical problems about mathematical concepts.Mathematical concepts are essential forms of thinking that reveal the relationship between spatial forms and quantities in the real world.It is a way of mathematical reasoning, judgment, proof Based on which is the carrier of mathematical ideas and methods.These concepts are the basis for students to correctly think about the problem in their study and enable students to creatively solve the problem.It is not only an important part of mathematics teaching but also the core of mathematics learning. The introduction of concepts A concept is formed in the memory of students is a certain process, teachers in the teaching process should be from the specific to the abstract, from the phenomenon to the essence.Leading students to gradually form the concept from the phenomenon to the essence, and the use of intuitive comparison method often Lecture concept effect than simply, in isolation
