数学是一门逻辑性、系统性很强的学科。学生学习是循序渐进的知识积累过程。因此,在教学中,应时刻注意由学生的生活经验和已有的知识导入到新知识的学习,从而降低学习坡度,提高学生学习的积极性;并注意知识的纵横联系,使之系统化、条理化,形成立体的知识网络,真正起到提高学生数学素质之目的。下面就《长方形的认识》这节课,谈谈我的做法和体会。一、利用已有知识经验为新知铺路搭桥学习新知之前根据学生已有知识设计基本训练,可以加强学生对旧知识的记忆,亦为新知学习作铺垫。同时,启动学生已有的生活经验,在原有认识结构上,寻找新知识的生长点而导入新课,这样激发了学习动 Mathematics is a logical and systematic discipline. Student learning is a gradual process of knowledge accumulation. Therefore, in teaching, we should always pay attention to the students ’life experience and existing knowledge into the learning of new knowledge, so as to reduce the learning gradient and improve students’ enthusiasm for learning; and pay attention to the vertical and horizontal links of knowledge to make it systematized The formation of three-dimensional knowledge network, the real play to improve the quality of students mathematics purposes. Below on the “rectangular understanding” of this lesson, talk about my approach and experience. First, the use of existing knowledge and experience to pave the way for the new knowledge Learning before the new knowledge based on the existing knowledge of students to design basic training, students can enhance memory of old knowledge, but also pave the way for new knowledge learning. At the same time, starting the students’ existing life experience, introducing the new lesson into the original knowledge structure and finding the new growth point of knowledge, thus stimulating the learning movement
