虚拟实验技术在分子生物学实验教学中的应用

Application of Virtual Experiment Technique in Molecular Biological Experiment Teaching

目的建立医学分子生物学虚拟实验教学平台,探索出有效的虚拟实验教学运行机制.方法将昆明医科大学2011级临床专业学生随机分为2组,虚拟实验技术教学组195人,传统实验教学组205人,采用问卷调查了解学生对教学效果的评价,并统计学分析2组期末考试成绩.结果同学对虚拟实验的教学方式接受程度较高,有助于同学对实验实际操作及理论知识的理解和掌握.2组期末考试成绩无统计学差异(P>0.05).结论虚拟实验技术作为一种新的教学手段,具备许多传统实验所不具备的优点,但其不能完全代替传统实验,在医学分子生物学实验教学中,应合理运用虚拟实验与传统实验两种教学手段.

Objective Set up virtual experimental teaching platform of medical molecular biology, and explore effective operating system of virtual experiment teaching. Methods 400 students of majored in clinical medicine in Kunming Medical University in Grade 2011 were randomly divided into the virtual experiment teaching group （n = 195 ） and the traditional experiment teaching group （n = 205 ）. We realized the teaching effect by questionnaire survey, and analyzed the final exam results of two groups statistically. Results The experiment teaching way of virtual experiment has been widely accepted by students, and it could help students to understand and master experiment operations and theory knowledges. No statistical difference was found between two groups on the final exam. Gonelusion Virtual experiment technology as a new teaching method has a lot of advantages, but it can＇t completely replace traditional experiments. We should use both the two kinds of teaching methods reasonally in the medical molecular biology experiment teaching.
