对一种典型振荡器实验方法的探讨

Inquiry on Typical Oscillator Experiment Teaching Method

在提倡素质教育的今天 ,模拟电子实验教学中仍存在一些理论与实际脱节的问题 ,例如有些即将毕业的大学生 ,对示波器和一些常用仪表还不怎么会用。造成这种问题的原因是有些学生在做实验时 ,遇到问题不愿意多加思考 ,只是简单的采取拆线重新连接电路的做法 ,从而失去了对实验现场的分析与动手使用仪器的训练机会 ,这将不利于教学改革的发展。面对这样的实际问题 ,本文笔者提出了解决实际教学中存在问题的有效方法。

In today of promotion quality education, there are still the problem of theory disconnected with practice in the teaching of analog electronics experiments. For example, Some students to graduate soon from university are still not able to operate the basic instruments correctly such as the oscilloscope ect. This problem is caused by following situation. Over a long period of time, not a few students encountered the problems when doing their experiments, they were not ready to add more than expected the consideration, only easy way of work taking the disconnection and reconnection of the wires in the electronic circuits of experiments, as a result they lost the analysis of experiment condition and the opportunity getting to work the training. This shall not benefit the present reform in education development. Being confrontation with so actual problem, the author proposes a individual concept to probe into a valid means by which the above problem can be resolved and illustrated using a typical Wen-bridge oscillator experiment.
