Under the pattern of cyber - education , open laboratories are becoming inseparable parts which still are weak in the process of teaching . as for electric experiment category , there are many problems in common , for instance , less safe in equipment systems , less functional in instrument protection , thus forcing students to spend large quantity of time reviewing , recording , and analyzing data , while students do experiment only with less time , which have negative effect on purpose of experiment , at the same time , this does not reflect benefits that internet brings us
然而当前大多数高校的实验教学环节还比较薄弱，其中对电类实验来说存在诸多共性问题，比如：实验系统安全性差，仪表保护功能少，导致实验器材损坏严重：仪表性能不稳定，零漂、温漂现象严重，元器件线性度校正不够，仪表测量精度差；学生做一次实验要花大量时间记录数据、整理数据、写实验报告，真正用在做实验上的时间并不多，从而使实验效率大大下降；同时也没有充分利用校园网所带来的便利和信息共享及互动的功能。
