摘要

角动量和角动量守恒定律是大学物理教学中的重点和难点。文章介绍了一套自制的集定性演示角动量的矢量性、定性演示和定量验证角动量守恒定律为一体的便携式角动量演示教具，探讨了其在研究型课堂演示实验教学过程中的应用。该教具主要由旋转圆盘、穿珠圆盘、电动机、变速控制器等部分组成。教具整体结构紧凑，方便携带，操作简便，现象十分明显，可将角动量矢量性和角动量守恒定律可视化，有利于突破角动量相关概念和规律的教学难点，实现高效课堂的生成。

Abstract:

Angular momentum and the law of angular momentum are key and diffieult points in college physicsteaching. lt introduces a self-made portable angular momentum demonstration instrument that integratesqualitative demonstration of the vectorization of angular momentum , qualitative demonstration and quantitativeverilication of the law of angular momentum conservation, and explores its application in classroom teachingThis teaching aid mainly consists of rotating dises ,ball piercing dises ,electric motors , variable speed controllersand other parts. The overall structure of teaching aids is compact, easy to carry and operate, and thephenomenon is very obvious.lt can visualize the vectorization of angular momentum and the law of angulalmomentum conservation , which is conducive to breaking through the teaching difficulties of concepts and lawsrelated to angular momentum and achieving efficient classroom generation.

Key words: angular momentum demonstration instrument vectorality law of angular momentum conservation classroom teaching
