掌握几何知识对学生今后的发展有着积极的意义。因此,数学教师应当遵从学生的认知规律,利用多样化的教学手段,引导学生准确把握几何的概念,让他们理解得又快又深。一、紧扣关键词,帮助学生认知概念本质概念是对客观事物本质属性的抽象概括。教材中几何概念往往是几个字词组合在一起形成的定义,概念中有几个关键字词是整个定义的点睛之笔,抓住这些关键字词是理解概念的关键所在。小学生年龄较小,认识的字词有限,让学生独
Grasp the geometric knowledge of the future development of students has a positive meaning. Therefore, mathematics teachers should follow the students’ cognitive rules and use diversified teaching methods to guide students to accurately grasp the concept of geometry and make them understand faster and deeper. First, closely linked to keywords, to help students understand the concept of the concept of nature is an abstract summary of the essential attributes of objective things. Geometry concepts in the textbook is often the definition of a few words together, the concept of several key words is the crowning touch of the entire definition, to seize these key words is the key to understanding the concept. Pupils are younger and have limited knowledge of the words to make them independent
