演示实验改进简析

Demonstrative Experiment Improvement Analysis

演示实验是中学物理课堂教学中一种重要且有效的教学方式,但由于课堂距离和上课时间等因素的限制有些演示实验在操作中会存在一些不足。本文通过对部分力学演示实验进行重新实践、分析,并在此基础上进行改进,尝试利用随手可取的生活物品进行演示实验,使得改进后的演示实验达到取材方便,制作简单,实验现象更加明显直观的目的,从而为物理课堂教学提供帮助。

The demonstration experiment is an important and effective teaching method in the middle school physics classroom.However,some demo experiments will have shortcomings due to the restriction of the class distance and the time of class.This paper tries to re practice some of the mechanical demonstration experiments and improve it.The goal of improved demonstration experiment is to carry out the readily available experiment phenomenon with the living items.As well as it can be provided to help for the physics classroom teaching.
