虚拟仿真实验在环境卫生学实验教学中的应用与效果评价

Application and Evaluation of Virtual Simulation Experiment in Experiment Teaching of Environmental Hygiene

目的:探讨虚拟仿真实验在预防医学专业课程环境卫生学实验教学中的应用和效果。方法:调查环境卫生学中-突发生活饮用水污染应急处置虚拟仿真实验的应用及效果。结果:仿真实验内容包括污染事件处置的整个流程。采用课前学生操作、课中答疑讨论、课后提交报告三段式全程考核教学模式。调查显示,67.17%的同学对虚拟仿真实验持认可的态度。超过95%的同学表示学习后掌握了应急处置过程。95.86%的学生表示喜欢这种教学方式。结论:虚拟仿真实验能够改善原有教学条件,提高实践教学的质量和效果,提升学生的基础知识、个人事件处理能力以及公共卫生职业素养。

Objective To explore the application and effect of virtual simulation experiment for emergency response to sudden domestic drinking water pollution in the experiment teaching of environmental hygiene in preventive medicine courses.Methods Using the emergency treatment experiment of sudden drinking water pollution,the teaching application and effect were carried out in the course of environmental hygiene.Results The virtual simulation experiment includes nine modules.In the process of teaching implementation,a three-stage and whole-process assessment teaching mode is adopted.Firstly,students learn by themselves and finish the virtual simulation experiment online,then,teacher’s answering and discussion during class,Finally,students submit report of the emergency disposal process after class.The survey on the evaluation of students’teaching effect shows that an average of67.17%of the classmates have an approval attitude towards the virtual simulation experiment.More than 95%of the students said they have mastered the emergency response and disposal ability after class.Over 95.86%students like this teaching model.Conclusion The application of virtual simulation experiment can improve the original teaching conditions,improve the quality and effect of practical teaching,and improve students’basic knowledge,personal event handling ability,and public health professional quality.
