要讲好一堂课,首先要备好课,教师要备好课,首先要注意知识的结构,新旧知识的联系,真正弄懂、弄通、弄透整个中学阶段的教材,搞清本与本、章与章、节与节的内在联系,如沪科版教材中简单机械在初二课本上有,初三课本上也存在,但各有侧重,初二时的简单机械着重让学生了解简单机械的分类及应用,而初三这一部分着重研究其在使用时的效率如何,怎样把握重点,引导学生将新旧知识有机地联系起来,让分散的知识点连接成线,形成知识网络,使其更系统化,更有利于学生掌握和运用,这都是备课时首先应注意的,

First, we must pay attention to the structure of knowledge, the link between old and new knowledge, and really understand, make, and learn through the teaching materials of the entire middle school stage. The intrinsic links between chapters, chapters, chapters, festivals, and festivals, such as the simple mechanical textbooks in the Shanghai edition, are also available in the second and third grade textbooks, but also exist in the third grade textbooks. The classification and application of machinery, and the third part of this part focuses on the efficiency of its use, how to grasp the key, guide students to organically link the old and new knowledge, connect the scattered knowledge points into a line, form a knowledge network, make it More systematic, more conducive to student mastery and use, this is the first thing to pay attention to when preparing lessons.
