Background: During the coronavirus disease 2019 (COVID-19) pandemic, medical colleges in China had to use online teaching. This study explored the effect of COVID-19 knowledge learning online in a flipped classroom based on micro-learning combined with case-based learning (CBL).
Methods: There were 74 undergraduate medical students who were randomly grouped to an observation group and a control group with 37 participants in each virtual classroom on the Network Teaching Platform. Students learning in the control group utilized face-to-face lecture with PowerPoint pre-provided, while students learning in the observation group were conducted in a flipped classroom based on micro-learning combined with CBL. We compared the effect of both formats of COVID-19 knowledge learning online and the impact on clinical practice attitude in two groups.
Results: All 74 students (100%) responded pretest, posttest and retention test, and completed the questionnaire online. Both formats significantly improved COVID-19 knowledge acquisition at the conclusion of online COVID-19 curriculum. Students’ knowledge test scores including total score and scores of five knowledge dimensions of COVID-19 were significantly higher in the observation group than those in the control group (P < 0.05). Compared with students in the control group, students in the observation group performed better in retention test and had a significantly more positive clinical practice attitude (P < 0.05 in all items).
Conclusion: A flipped classroom based on micro-learning combined with CBL showed greater effectiveness in COVID-19 knowledge gain in undergraduate medical students and made their attitude toward clinical practice more positive.
