示波器在物理实验教学中的应用

The Application of Oscilloscope in the Experimental Teaching

以示波器使用为中心,对传统的教学内容进行了改革与创新。实验中用不同的方法对学生自制信号源进行了频率校准,锻炼了学生的发散思维能力;通过让学生观察稳压源各工作端口信号经过整流和滤波后的变化,培养了他们学以致用的思想。通过实验内容的合理编排与设计,学生的实际操作及解决问题的能力得到了提高,该实验收到较好的教学效果且受到了学生的欢迎。

In this paper,as the oscilloscope as the center, the traditional contents of oscilloscope are reformed and innovated. In the experiment, we ask the students to calibrate the self-frequency signal source with two different methods, which exercises divergent thinking ability of students. By observing the changing of the working port regulator signal after rectifier and filter, the students＇ thinking of using their knowledge to the reality is set up. Through the experiment contents being reasonably layouted and designed, the students＇ practical and problem-solving abilities have been improved, and the effect of this experiment is good and it is welcomed by the students.
