“眼睛与眼镜”不仅是凸透镜成像规律的拓展,更是初中光学知识的重要应用,在初中光学教学中具有重要地位。本文以高端备课的研究视点,深入研究“眼睛与眼镜”教学的物理内涵,以期对这节课的教学有所裨益。一、问题提出与分析现行人教版教材首先将眼球比作一架照相机,并对眼球的结构进行介绍。随后,阐述晶状体和角膜的共同作用相当于一个凸透镜,把来自物体的光会聚在视网膜上,形成物体的像,视网膜上的感光细胞受到光刺激产生信号,通过视神经把信号传输 “Eyes and glasses ” is not only the development of convex lens imaging law, but also an important application of optical knowledge in junior high school, which plays an important role in the optical teaching of junior high school. In this paper, the high-end preparation of the research perspective, in-depth study of the “eye and glasses” teaching the physical connotation, with a view to the teaching of this lesson is beneficial. First, the question put forward and analysis of the current peopl teaching textbook first eye compared to a camera, and the introduction of the structure of the eye. Subsequently, the lens and the cornea explain the role of the equivalent of a convex lens, the light from the object in the retina to form the image of the object, the photoreceptor cells on the retina by light stimulation signal generated through the optic nerve signal transmission
