医学细胞生物学虚拟仿真实验教学的效果评价研究

Evaluation study on the effectiveness of virtual simulation laboratory teaching of medical cytology

目的利用虚拟仿真系统开展医学细胞生物学实验教学,探讨虚拟仿真教学平台的应用效果。方法选取本校临床专业2022级118名本科生作为研究对象,随机分为两组,传统教学方式组(未使用虚拟仿真软件辅助教学),虚拟仿真教学组(在传统教学方式上增加虚拟仿真实验环节)。连续观察一个章节学习效果,分析使用虚拟仿真软件辅助教学前后学生成绩、和教学评价的差异。结果虚拟仿真教学组学生理论测试成绩(91.24±1.26)高于传统教学组成绩(85.17±3.65)分,差异有统计学意义(P<0.01)。在课堂参与度评分方面,实验组课堂讨论参与度、合作与协作能力,以及提问能力评分均高于对照组,两组比较差异有统计学意义(分别为t=-4.06,-4.91,-6.86,均P<0.01)。在对两组学生不同能力的评价方面,实验组学生在学习能力、理论知识掌握能力、团队协作能力、自主学习能力和自我展示能力均高于对照组,差异均有统计学意义(均P<0.01)。实验组对教学的总体满意度也高于对照组,差异有统计学意义(Z=-2.74,P=0.004)。结论虚拟仿真实验教学平台的应用,可以有效地提升教学效果。该平台强化了学生对理论知识的掌握,提高了操作技能。

Objective To explore the application effect of virtual simulation teaching platform in medical cell biology experimental teaching.Methods Virtual simulation technology was utilized to build an experimental teaching platform for medical cell biology including learning mode and examination mode.One hundred and eighteen undergraduate students of the 2022 class of clinical expertise at the Hebei North University were selected for the study.Randomized into two groups,Group of traditional teaching methods(without the use of virtual simulation software to assist teaching and learning),Virtual Simulation Teaching Group(adding a virtual simulation lab session to the traditional teaching method).Observing the learning effects of one chapter in a row,Analyze the differences in student achievement,and instructional evaluations before and after using virtual simulation software to aid instruction.Results Students'scores on the theory test were higher in the virtual simulation group(91.241.26)than in the traditional teaching group(85.173.65),The difference between the two groups was statistically significant(P<0.01).In terms of classroom participation scores,the experimental group's classroom discussion participation,cooperation and collaboration ability,and questioning ability scores were higher than those of the control group,and the differences between the two groups were statistically significant(t=-4.06,-4.91,and-6.86,respectively,all P<0.01).In the evaluation of the different abilities of the two groups of students,the experimental group was higher than the control group in learning ability,theoretical knowledge mastery,teamwork ability,independent learning ability and self-presentation ability,and the difference between the two groups was statistically significant.In addition,the experimental group's overall satisfaction with teaching was higher than that of the control group,and the difference between the two groups was statistically significant(Z=-2.74,P=0.004).Conclusion The application of virtual simulation experimental teaching platform can effectively improve the teaching effect.The platform strengthens students'mastery of theoretical knowledge and largely improves their mastery of operational skills.
