眼球的折光系统是继学生了解了凸透镜成像规律的基础上进行的.可以先用自制 CAI软件动画展示凸透镜成像规律,形成知识的迁移,探究得到眼球折光系统的组成.再通过设计一系列探究性实验方法揭示眼球折光系统的成像及原理,进而运用调查法、自学法、探究法、竞猜等形式学习近视的成因和矫正,最后运用对比思维方法探究远视的成因和矫正. The refractive system of the eyeball is based on the student’s understanding of the imaging law of the convex lens. You can use the self-made CAI software to animate the imaging law of the convex lens to form a knowledge transfer and explore the composition of the eyeball refraction system. Then design a series of inquiries. The experimental method reveals the imaging and principle of the eyeball refraction system, and then uses survey methods, self-study methods, inquiry methods, and quiz to learn the causes and corrections of myopia, and finally uses the comparative thinking method to explore the causes and corrections of hyperopia.
