物理学是一门以实验为基础的学科,物理上的许多规律都是通过实验总结出来的,实验过程设计得是否巧妙、实验现象的观察是否明显将直接影响到实验的效果,影响学生对物理概念的建立和对物理规律的理解,更会影响到教学过程中教师对重、难点的突破.本文从实验设计的角度介绍了如何利用发光二极管进行巧妙设计来达到突破教学难点的目的.
Physics is an experiment-based discipline. Many laws of physics are summed up through experiments. Whether the experimental process is designed is clever or not. Obviously, the observation of the experimental phenomena will directly affect the experiment’s effect and affect students’ The establishment of the concept and the understanding of the laws of physics can even affect the teacher’s heavy and difficult breakthroughs in the teaching process.This paper introduces how to use LEDs to design cleverly so as to achieve the purpose of breaking through teaching difficulties from the perspective of experimental design.
