“测量玻璃的折射率”实验原理简单,操作简便.也正因为如此,以它为命题内容来考查学生时,如果不加变换则学生对它基本上无思维障碍.为了考查学生能力,就必须对现有实验进行变换创新,而创新方向的不同带来了对此内容考查方法的多样性. “Measuring the refractive index of glass ” experimental principle is simple, easy to operate and therefore because of it as the proposition content to examine the students, without changing the students to it basically without thinking obstacle.In order to examine the student ability, It is necessary to transform and innovate the existing experiments, and the differences in innovation direction bring about the diversity of methods for examining this content.
