基于网络教学平台的线上课堂与线下课堂的病毒学检验教学效果比较

Teaching effects of online and offline classroom teaching based on the network teaching platform in Laboratory Sciences for Virus Infection Testing

目的:探讨基于网络教学平台的线上课堂与线下课堂的病毒学检验教学效果。方法:利用我校引进的“知行医苑”教学平台,成功建设了病毒学检验课程的网络教学平台。以2017级(n=54)和2018级(n=55)卫生检验与检疫专业本科生为研究对象。2017级学生采用基于网络教学平台的线上课堂教学,2018级学生采用基于网络教学平台的线下课堂教学。通过期末考试成绩和自制调查问卷评价教学效果。结果:线上课堂组期末考试成绩显著高于线下课堂组(P<0.01)。2组在网络教学平台的学习情况差异无统计学意义(P>0.05)。2组对混合式教学方法的评价各方面差异无统计学意义(P>0.05)。2组对教学效果的评价中,线上课堂组在课堂专注度、师生互动性方面满意率显著低于线下课堂组(P<0.05)。结论:基于网络教学平台的线上课堂和线下课堂教学各有优缺点,但在教学效果评价中线下课堂优于线上课堂。混合式教学方法能够提高学生自主学习能力以及分析和解决问题的能力。

Objective:To explore the teaching effects of online and offline classroom teaching based on the network teaching platform in Laboratory Sciences for Virus Infection Testing.Methods:A network teaching platform for Laboratory Sciences for Virus Infection Testing was constructed based on the“Zhi Xing Yi Yuan”platform.The undergraduates of grade 2017(n=54)and grade 2018(n=55)majoring in Health Inspection and Quarantine were selected as research objects.The grade 2017 students received online classroom teaching based on the network teaching platform,and the grade 2018 students received offline classroom teaching based on the online teaching platform.The final exam score and self-made questionnaires were used to evaluate the teaching effect.Results:The final exam score of the online classroom group was significantly higher than that of the offline classroom group(P<0.01).There was no statistically significant difference in the learning situation between the two groups on the network teaching platform(P>0.05).There was no statistically significant difference in the evaluation of blended teaching method between the two groups(P>0.05).In the evaluation of the teaching effect,the satisfaction rates of the online classroom group in terms of classroom concentration and teacher-student interaction were significantly lower than those of the offline classroom group(P<0.05).Conclusions:The online and offline classroom teaching based on the network teaching platform have their own advantages and disadvantages,but offline classroom teaching are better than online classroom teaching in the evaluation of teaching effects.Blended teaching method can improve students′autonomous learning ability and the ability to analyze and solve problems,and is worthy of application.
