虚拟仿真实验在病毒学检验教学中的应用研究

Application of virtual simulation experiment in the teaching of Laboratory Sciences for Virus Infection Testing

目的:探讨虚拟仿真实验在病毒学检验教学中的应用价值。方法:以2020级卫生检验与检疫专业本科生(n=58)为研究对象。在病毒学检验课程教学中纳入“BSL-2实验室中流感病毒分离鉴定虚拟仿真实验”。通过自制调查问卷评价虚拟仿真实验的应用效果。结果:共50名学生有效填写调查问卷。在使用虚拟仿真实验后,96.0%学生认为该实验的仿真度较高。学生能了解实验的仪器组成、内部构造、操作流程和注意事项。52.0%学生认为该实验对自主学习有影响。学生认为该实验可以增加课程趣味性(88.0%)、增加对理论知识的掌握(60.0%)、提高分析和解决问题的能力(46.0%)。72.0%学生认为虚拟仿真实验运行速度慢。学生评价该实验优点前3位的是操作容易、不会损坏仪器及不担心实验中会出现危险、对专业学习有用,有助于理解所学知识。该实验缺点前3位的是对自己动手能力没有提升、没有机会熟悉仪器的使用、与真实实验的感觉有差异,实验过程过于理想化。66.0%学生认为虚拟仿真实验应与传统教学相互补充。结论:虚拟仿真实验可进行传统实验室难以开展的危险性实验,能够提高学生对理论知识的掌握,提升学习兴趣,提高分析和解决问题的能力。但其应用仍存在一些问题,应与传统实验教学有机结合,从而提高教学效果。

Objective:To investigate the application value of virtual simulation experiment in the teaching of Laboratory Sciences for Virus Infection Testing.Methods:Undergraduate students(n=58)majoring in Health Inspection and Quarantine of grade 2020 were selected as the research objects.The"Virtual simulation experiment of influenza virus isolation and identification in BSL-2 laboratory"was included in the teaching of Laboratory Sciences for Virus Infection Testing.The application effect of the virtual simulation experiment was evaluated by a self-designed questionnaire.Results:A total of 50 students completed the questionnaire effectively.After completing the virtual simulation experiment,96.0%of the students thought that the simulation degree of the experiment was high.Students could understand the instrument composition,internal structure,operation process,and matters needing attention.And 52.0%of the students thought that the experiment had an impact on autonomous learning.Students believed that the experiment could improve their interest in the course(88.0%),increase their mastery of theoretical knowledge(60.0%),and improve their ability to analyze and solve problems(46.0%).And 72.0%of the students thought that the running speed of the virtual simulation experiment was slow.The top three advantages of the experiment evaluated by students were easy operation,no damage to the instrument and no worry about the dangers in the experiment,and helpful to understand the knowledge.The top three disadvantages of this experiment were no improvement in practical ability,no familiarity with the use of instruments,different feelings from the real experiment and too idealized experimental process.And 66.0%of the students thought that virtual simulation experiments should complement traditional experimental teaching.Conclusions:Virtual simulation experiment can carry out dangerous experiments that are difficult to perform in traditional laboratories.It can improve students'mastery of theoretical knowledge,enhance their interest in learning,and improve their ability to analyze and solve problems.However,there are still some problems in its application,which should be combined with traditional experimental teaching to improve the teaching effect.
