The Effectiveness of a Serious Game Versus Online Lectures for Improving Medical Students' Coronavirus Disease 2019 Knowledge.

The sudden disruption of university teaching caused by the coronavirus disease 2019 (COVID-19) pandemic has forced universities to switch to online teaching. It is vital for graduating medical students to learn about COVID-19 because they are likely to treat COVID-19 patients after graduation. We developed a COVID-19 lesson for medical students that used either an online lecture or a serious game that we designed. The aim of this study is to explore the effectiveness of a serious game versus online lectures for improving medical students' COVID-19 knowledge. From our university's database of knowledge scores, we collected the prelesson, postlesson, and final test knowledge scores of the students who participated in the lesson and conducted a retrospective comparative analysis. An analysis of scores concerning knowledge of COVID-19 from prelesson and postlesson tests shows that both teaching methods produce significant increases in short-term knowledge, with no statistical difference between the two methods ( > 0.05). The final test scores, however, show that the group of students who used the game-based computer application scored significantly higher in knowledge retention than did the online lecture group ( = 0.001). In the context of the disruption of traditional university teaching caused by the COVID-19 pandemic, the serious game we designed is potentially an effective option for online medical education about COVID-19, particularly in terms of its capacity for improved knowledge retention.
