初中物理《常见光学仪器》教学时,学生对显微镜和望远镜的原理及特点区分不开,难以掌握.为便于学生正确区分、轻松把握显微镜和望远镜原理和特点,我在教学中根据显微镜和望远镜成像光路图,将显微镜和望远镜的基本原理和特点作了对比分析,总结了五同五不同. Junior high school physics “common optical instruments” teaching, the students on the microscope and telescope principles and characteristics of the distinction is not open, it is difficult to master .In order to facilitate the students to correctly distinguish, easy to grasp the principle and characteristics of microscopes and telescopes, I teach in microscopy and telescope imaging Light Road map, the microscope and telescope basic principles and characteristics for a comparative analysis, summed up five different five.
