We appraised the effectiveness of online (Zoom) delivery versus live campus-based delivery of lectures in biochemistry and genetics courses and assessed the security of remote versus campus-administered exams.
Participants were 601 students entering Michigan State University College of Osteopathic Medicine in 2019 or 2020. The former cohort completed courses and exams on campus, while the latter completed courses online due to the COVID-19 pandemic. For the biochemistry and genetics courses, the same lecturers delivered the same content and used identical exam questions for assessments in 2019 and 2020. The investigators compared percent correct for each question in 2019 and 2020.
This study found 84 of 126 (67%) of the questions yielded little difference (3% or less in % correct) between live delivery and Zoom delivery. For questions whose % correct index differed by 4% or more, Zoom delivery yielded a better performance for 16 questions (13%), while 19 questions (15%) showed live lectures performed better. Seven of the questions (6%) had an identical mode of delivery in 2019 and 2020 (e.g., self-study exercise). These served as "control questions" for which equivalent student performance was expected. The 126 questions analyzed spanned a wide range in the % correct index, from 60% correct to > 90% correct.
The results suggest that Zoom and on-campus delivery of the content in biochemistry and genetics yielded similar achievement of course objectives. The high concordance, between 2019 and 2020, of the % correct for individual questions also speaks to exam security including online proctoring.
我们评估了在生物化学和遗传学课程中，通过在线（Zoom）授课与在校园现场授课的效果，并评估了远程考试与校园管理考试的安全性。
参与者为2019年或2020年进入密歇根州立大学整骨医学院的601名学生。前一组在校园内完成课程和考试，而后一组由于新冠疫情在网上完成课程。对于生物化学和遗传学课程，相同的讲师在2019年和2020年讲授相同的内容并使用相同的考试题目进行评估。研究人员比较了2019年和2020年每个问题的正确百分比。
本研究发现，126个问题中有84个（67%）在现场授课和Zoom授课之间差异不大（正确百分比相差3%或更少）。对于正确百分比指数相差4%或更多的问题，Zoom授课在16个问题（13%）上表现更好，而19个问题（15%）显示现场授课表现更好。其中7个问题（6%）在2019年和2020年的授课方式相同（例如自学练习）。这些作为“对照问题”，预期学生表现相当。所分析的126个问题的正确百分比指数范围很广，从60%正确到>90%正确。
结果表明，在生物化学和遗传学中，通过Zoom和在校园授课在实现课程目标方面取得了相似的成绩。2019年和2020年单个问题正确百分比的高度一致性也说明了包括在线监考在内的考试安全性。
