基于数字电路的线上实验教学模式探索

Exploration on Teaching Mode of Online Experimental Based on Digital Circuits

数字电路实验是理工科高等院校的基础实验课程,现有实验箱授课方式时空不够灵活,虚拟仿真实验授课方式无法还原真实实验操作,两者均不能满足学生的课程学习需求。针对以上问题,该文构建了基于实际硬件电路的远程在线实验教学平台,通过互联网保证学生能随时随地在真实的硬件电路上进行实验操作。设计多层次多类型的实验教学内容和利用线上数字化教学资源,构建远程数字电路课程的实验教学体系,使在线实验教学与线下实验教学在实验设计、操作方法、测试步骤等方面实质等效,提升了实验教学效果。

Digital circuit experiment is a fundamental experimental course in science and engineering colleges.Existing teaching methods of experimental box are not flexible enough in time and space,and virtual simulation experiment cannot restore the real experiment operation,both of which can not meet the needs of students’course learning.In response to the above problems,a remote online experimental teaching platform based on actual hardware circuits has been built.By using the internet,students can operate real hardware circuit experiments at any place and any time.Multi-level and multi-type experimental teaching content and online digital teaching resources are designed to construct an experimental teaching system for remote digital circuit courses.The online experimental teaching achieves substantial equivalence with offline experimental teaching in the experimental design,operation methods,testing steps and other aspects,improving the effectiveness of experimental teaching.
