Coronavirus Disease 2019 (COVID-19) Learning Online: A Flipped Classroom Based on Micro-Learning Combined with Case-Based Learning in Undergraduate Medical Students

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: <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.
