数学是系统性很强的学科,新旧知识密不可分,在学习新知识的同时,旧知识有相当大的影响和作用,在教育心理学中称此为“学习的迁移”。初中数学教材中,存在着大量的类似的定义和概念,知识之间存在着紧密的联系,类比成为知识联系的纽带,教师如果能够适当引导学生加以类比,旧知识对新知识就能产生积极的促进作 Mathematics is a highly systematic subject. Both old and new knowledge are inseparable. While learning new knowledge, old knowledge has a considerable influence and effect. In educational psychology, it is called “learning transfer”.

There is a close connection between knowledge and analogy as a link of knowledge connection. If teachers can properly guide students to analogy, old knowledge can produce positive Promote work
