虚实结合的多元化实验教学研究

Research of Diversified Experimental Teaching with the Virtual-actual Combination

基于大型仪器设备开展的传统实验教学在软硬件配套和实践能力培养方面存在诸多限制,为提升实验教学成效,拓展知识面的广度与深度,虚拟仿真技术进入课堂。但虚拟实验操作利弊兼具,不能完全满足实验教学的目的。为寻求课程建设与人才培养的科学合理途径,以生物大分子表征及成像技术课程为例,通过采用虚实结合的模式,以虚拟仿真实验辅助现场实践教学,分设线上线下双重考核标准,让“多元化”体现在知识板块的组成以及教学形式的多样化上。此外,将平行对照实验引入实践教学环节,科学合理地分析数据、协同合作,实现人力与物力的资源优化,保障课程考核的公平有效。

The traditional experimental teaching based on large-scale instruments has many limitations in hardware and software matching and practical ability training.In order to improve the effectiveness of experimental teaching and expand the breadth and depth of knowledge,the virtual simulation technology has been used in the classroom.However,operation through virtual experiment has both advantages and disadvantages,which could not completely meet the purpose of experimental teaching.To find a scientific and reasonable way for the curriculum construction and talent training,taking the course of“Characterization and Imaging Technology of Biological Macromolecules”as an example,the mode of virtual-actual combination is adopted,which means the virtual simulation experiment should be used to assist the on-site practice teaching,and the online-offline assessment standards need to be set,so that the“diversity”would been reflected in the composition of knowledge modules and teaching forms.In addition,a parallel controlled experiment is introduced into practice teaching in order to analyze data scientifically and rationally,which can optimize human and material resources and ensure the fairness and effectiveness of course assessment.
