利用自制教具构建光的折射模型

Constructing the light refraction model by self-made teaching device

综合初中物理教材中“光的折射”设计理念,自制了实验装置.通过该实验装置可以开展折射规律、趣味捕鱼、虚像位置真实呈现、全反射、生活中折射现象扩展解释、海市蜃楼模拟等实验,并能够体现视觉表征学习方法,变抽象为形象,从而培养学生的建模能力.

Synthesizing the design concept of the refraction of light in the junior high school physics textbooks,the experimental device was developed.The experimental device could performe xperiments on the law of refraction,interesting fishing,real representation of virtual image position,total reflection,extended interpretation of refraction phenomenon in life,mirage simulation,and so on.It could also reflect the learning method of visual representation and transform abstraction into image,so as to cultivate students’modeling ability.
