突发公共卫生事件期间线上和线下团队学习法在医学本科生细胞生物学教学中的应用

Application of Online and In-Person Team-Based Learning Methods in Cell Biology Teaching for Medical Undergraduate Students during the Public Health Emergency Events

团队学习(team-based learning, TBL)结合了主动和协作学习,同时合并了翻转课堂教学法和基于问题的学习方法。然而突发公共卫生事件给TBL效果带来了一定的挑战。该研究调查了TBL对医学本科生细胞生物学课业成绩的影响,比较了经典的面对面(线下方式)和由于疫情影响而进行的线上团队学习方式。在传统的两节授课之后,笔者团队在细胞生物学课程中引入了非必修TBL环节,然后将参加TBL(线上和线下)和没有参加TBL同学的考试成绩和作业表现进行了比较。结果显示,无论是线上还是线下参加TBL的同学(n=120)在考试成绩(P<0.05)和相关课程作业(P<0.05)中都比未参加的同学(n=175)表现得更为优异。与未参加TBL的同学相比线上和线下参加TBL的两组同学的成绩分布更为集中,且未通过考试的同学分布于未参加TBL的同学中。线上和线下TBL两组之间在考试成绩(P=0.184 0)和课程作业(P=0.359 7)方面并没有明显差异。该研究显示,线上和线下TBL均可以成功地补充传统的课堂教学内容,进而提高学生学习能力,尤其是对于复杂的医学科目。该研究结果表明,线上TBL也可以收获很好的效果,这就表明在高等教育中可以灵活使用TBL教学方法。

TBL(team-based learning)combines active and collaborative learning and incorporates flipped classroom teaching method and problem-based learning method.However,the public health emergency events have brought some challenges to the effect of TBL.This study investigated the impact of TBL on the academic performance of Cell Biology for medical undergraduates.This study compared the classic face-to-face approach(inperson)with the online team learning approach due to the impact of the epidemic.After two traditional lectures,non-compulsory TBL was introduced into the course of Cell Biology.This study compared the test results and homework performance of students who participated in TBL(online and in-person)and those who did not.The students who participate in the TBL(n=120)online or in-person did better in the examination(P<0.05)and related course assignments(P<0.05)than those who did not(n=175).Compared with the students who did not participate in the TBL,the scores of the online and in-person groups were more concentrated,and the students who did not pass the exam were distributed among the students who did not participate in the TBL.There was no significant difference between online and in-person TBL groups in terms of test scores(P=0.1840)and course assignments(P=0.3597).Online and in-person TBL can successfully supplement the traditional classroom teaching,thereby improving students’learning ability,especially for complex medical subjects.This research results show that good performance can also be achieved through online TBL,which indicates that TBL teaching methods can be flexibly used in higher education.
