“测定玻璃折射率”是高中物理教学的一个重要实验,实验目的是利用光的折射定律测定玻璃的折射率,加深对折射定律的理解,实验关键是确定光的光路图。通过实验让学生自行探究折射率的测定方法,体会探究的过程。只有切实理解、掌握实验原理和方法,才能以不变应万变,达到知识迁移和举一反三的效果,才能培养学生的思维变通能力,即培养学生的创新思维。 “Determination of glass refractive index ” is an important experiment in high school physics teaching. The purpose of the experiment is to determine the refractive index of glass by using the law of refraction of light and to deepen the understanding of the law of refraction. The key of experiment is to determine the optical path of light. Experiment by allowing students to explore the determination of refractive index, experience the process of inquiry. Only by comprehending and mastering the principle and method of experiment can the students be able to cultivate students’ creative thinking by keeping the status quo unchanged and achieving the effect of knowledge transfer and giving top priority to others.
