摘要
人教版八年级上册"凸透镜成像规律"这一章节的主要内容有光的折射、成像规律等,所以在教学中,教师应该从多个角度出发,让学生懂得凸透镜在不同情境下成像的基本情况。基于此,本文从初步认知、教学方案、虚拟实验和生活探索四个方面为出发点,重点探讨了这一知识的教学策略,以期为初中物理教师教学提供一定的参考。
The main contents of the chapter "imaging law of convex lens" in the eighth grade volume I of PEP include light refraction,imaging law,etc.,so in teaching,teachers should start from multiple angles to let students understand the basic situation of convex lens imaging in different situations.Based on this,this paper focuses on the teaching strategies of this knowledge from four aspects: preliminary cognition,teaching scheme,virtual experiment and life exploration,in order to provide some reference for junior high school physics teachers.
