开发课堂实验 激发学生学习兴趣——自制磁滞回线演示教具

Developing the In-class Demonstrating Experiments Stimulating the Students’ Learning Interest Self-made Magnetic Hysteresis Loop Demonstrating Experiment Tool

物理学是一门以实验为基础的科学，课堂演示实验是物理教学的重要手段。它可将抽象的概念变为直观的现象和具体实在的数据；把枯燥的理论变为生动活泼的现实情景，吸引学生的注意力，增加感性认识，激发学生的学习兴趣和求知欲望。教学实践中我们非常重视演示实验的开发研制工作，并且收到了良好的教学效果。

Physics is a science based on experiments; in--class experiment is a very important way of phys- ics teaching. It can turn the abstract concept into visual phenomenon and specific data, the dull theory into vivid present scene, and attract the students~ attention, so that they can have a better perceptual knowl- edge, and more interest in learning and stronger desire to learn physics. In teaching, we take the develop- ment of administrating experiment tool, and have a very better effect in teaching.
