基于共享虚拟仿真资源的污水处理教学实践

Teaching Practice of Sewage Treatment Based on Shared Virtual Simulation Resources

在疫情防控常态化的背景下,环境工程专业的实践越发受到宏观因素的制约,成为了提升学生实践能力的瓶颈。基于国家虚拟仿真实验教学课程共享平台的典型项目,在污水厂运行与管理课程教学和认识实习中开展“双点切入”教学探索,探讨了虚拟仿真教学在不同阶段的适用性,对仿真程序和教学设计中存在的不足进行了探讨。结果表明,虚拟仿真项目在认识实习和污水厂运行与管理课程中均发挥了良好作用,但在认识实习中的适用性更强。为培养学生解决复杂工程问题能力,虚拟仿真项目应在模型的仿真度、操作的自由度以及程序本身的功能性上做出提升。

Under the background of regular epidemic prevention and control,the practice of environmental engineering is increasingly restricted by macro factors such as safety,which becomes the bottleneck of improving students'practice ability.Based on the typical project provided by iLAB-X.com,a“Two point”teaching method was implemented in cognition practice and operation and management of wastewater treatment plant course.In this research,the applicability of virtual simulation in different teaching stages was discussed,the shortcomings of VS program and teaching design was both analyzed.The results show that,VS played a positive role in both cognition practice and operation and management of wastewater treatment plant course,but it seems more applicable in cognition practice.To cultivate students'ability to solve complex engineering problems,VS projects should improve the authenticity,functionality and operational freedom of program.
