教师要想上好每一节课,最基本的要求是要读懂教材、理解教材、吃透教材。作为一名数学教师,研读教材要做到以下几点:研读教材,弄清知识脉络。数学知识具有连续性、渐进性、系统性,数学教材的编排遵循了数学知识的一系列规律,教师在研读教材时,一定要弄清知识的脉络,比如某一知识是由哪些知识生发拓展而来的,是为今后哪些知识的学习服务的,某一知识的学习与其他哪些知识有关系、有关联,要想学习某一知识必须具备哪些知识基础等等。比如在教学“减法各部分之 Teachers want to make every good class, the most basic requirement is to read the textbook, understand the textbook, thorough textbook. As a math teacher, to study textbooks to do the following: study textbooks, to clarify the knowledge. Mathematical knowledge is continuous, progressive and systematic. The arrangement of mathematics textbooks follows a series of laws of mathematical knowledge. When teachers study textbooks, it is necessary to find out the context of knowledge, such as which knowledge germs develop from a certain knowledge To come, what knowledge to learn for the future service, a knowledge of learning and what other knowledge is related to the association, in order to learn a knowledge must have which knowledge base and so on.
