《探究凸透镜成像规律》这一节的教学内容较多,逻辑关系较复杂,对学生的思维能力要求较高,如何避免假探究、强硬塞,让学生真正经历探究过程,在实验数据的基础上深入分析,水到渠成地得出凸透镜成像规律,一直以来是一线教师关注的问题.2015年11月下旬,笔者在六合励志学校进行了一节《探究凸透镜成像规律》的研讨课,在课后的交流过程中,听课的老师们畅所欲言、各抒己见,笔者也是受益匪浅、感触颇多,现将精彩片段记录与此,并略
The section “Exploring the Law of Convex Lens Imaging” has more teaching content and more complicated logic. It has a higher requirement for students’ thinking ability. How to avoid spurious inquiry and hard plugging allows students to really experience the inquiry process based on experimental data. In-depth analysis of the law of lenticular imaging in water to reach the ground has always been a concern for front-line teachers. In late November 2015, the author conducted a seminar on “Learning the law of convex lenses” in the Liuhe Inspirational School, and exchanged ideas after class. During the process, the teachers who listened to the lectures expressed their opinions freely and expressed their opinions. The author also benefited a lot and felt a lot. Now we record the highlights with this.
