基于网络实验装置的常规水处理实验教学项目建设

Web-based Experimental Installation Construction of Conventional Water Treatment Experimental Teaching Project

高校常规水处理实验教学由于实验学时数少、实验场地不足等原因使实验内容和形式受到限制,影响学生实践创新能力培养。实验装置是水处理实验教学的重要组成部分。为突破常规实验教学开展在时间与空间上的限制,尝试将网络通信、传感器和控制技术应用在实验装置上,让学生通过网络操作完成实验。实践应用表明,在线实验能产生良好的教学效果,在保证操作过程体验的同时,实验操作自由度激发了学生的实践积极性,实验内容深度和广度都有所拓展。这种在线实验教学方式促进了实验教学资源共享,是常规实验教学模式的有益补充。

Conventional water treatment experimental teaching in colleges and universities cause limitations on the experimental contents and form with narrowsite and schedule.The effects of the limitation on capacity development of practice and innovation are negative.Experimental installation are key components of water treatment experimental teaching,on which the elements of network communication,sensing and regulating are used to get a online operation in order to breakthrough the restrictions of site and schedule.The application results indicated a satisfactory teaching effectiveness.Practical enthusiasm,aroused with the liberation from operational restrictions without cutting the process experience,expanded the depth and breadth of experimental contents.The online method is a beneficial supplement to routine experimental teaching,which promotes efficient work of the students and shareable experimental resource.
