众所周知,数学概念是数学知识结构的联系点,由其反映的数学思想方法是联系数学知识的强力纽带。教学目标的制定,教学方法的选择,教学过程的设计,教学效果的评价等都围绕着数学概念。为了使学生对数学概念的透彻了解和巩固,达到概念教学的最佳,那么,对数学概念的教学要进行优化。结合本人的教学经验,要优化数学概念教学,应做好以下几点:一、情境创设,事过功倍数学概念是揭示物质的本质属性与共同特征的。具有抽象性、复杂性和严密性,并蕴含着丰富的内涵,具有固定和同化新知识的功能。概念的导入是教师引导学生迅速进入学习状态的一个重要环节。一个引人人胜的数
It is well-known that the concept of mathematics is the contact point of the structure of mathematical knowledge, and the mathematical thinking method reflected by it is a powerful link in connection with mathematical knowledge. Teaching objectives, the choice of teaching methods, teaching process design, evaluation of teaching effectiveness are all around the concept of mathematics. In order to make students understand and consolidate the concept of mathematics, to achieve the best concept of teaching, then the concept of mathematics teaching to be optimized. Combining my teaching experience, to optimize the teaching of mathematical concepts, we should do the following: First, the creation of the situation, the multiplication of mathematical concepts is to reveal the essential attributes of the material and common characteristics. It has abstraction, complexity and rigor, contains rich connotation, and has the function of fixing and assimilating new knowledge. The introduction of the concept is an important part of the teacher to guide students to quickly enter the learning state. A fascinating number
