一、教材分析1.教学内容的地位和作用《显微镜和望远镜》是人教版初中物理第八册第五章“透镜及其应用”第五节的教学内容,它是在学生掌握了凸透镜成像规律的基础上教学的,也是前面所学知识的扩展。让学生知道两个凸透镜的组合所产生的神奇效果,激发学生探索物理知识的热情。学习显微镜和望远镜的知识,对学生加深理解凸透镜成像原理,了解科学知识的应用,提高自身的科学素质都是有益的。2.教学目标知识目标:了解显微镜、望远镜的基本结构。
First, the textbook analysis 1. The status and role of teaching content “Microscopes and telescopes” is the PEP Junior High School physics eighth chapter fifth chapter “lens and its application,” the fifth section of the teaching content, which is mastered in the students Convex lens imaging based on the law of teaching, but also an extension of the knowledge learned earlier. Let students know the magical effect of the combination of two convex lenses, to stimulate students enthusiasm to explore physical knowledge. Studying the knowledge of microscopes and telescopes is beneficial for students to understand the principle of convex lens imaging, understand the application of scientific knowledge and improve their own scientific quality. 2. Teaching Objectives Knowledge Objectives: To understand the basic structure of the microscope, telescope.
