Abstract：
BACKGROUND: Massive open online courses (MOOCs) have become innovative open-learning approach in medical education. This study aimed to evaluate the dynamic changes in the construction and application of medical MOOCs before and after the coronavirus disease 2019 (COVID-19) pandemic in China.
METHODS: The dynamic changes of usages about medical MOOCs before and after 2020 were mainly searched on the Smart Education of China Higher Education platform, and the detailed learning profiles and outcome indicators were further analyzed using 40 national first-class medical MOOCs from \'zhihuishu\' platform.
RESULTS: A total of 2,405 medical MOOCs were exported from the Smart Education of China Higher Education platform, of which 1,313 (54.6%) were launched since 2020. The total and average numbers of participants of 141 national first-class medical MOOCs peaked during the initial spread of COVID-19 in 2020. We further analyzed the dynamic usage of MOOCs from 2018 to 2022 based on 40 national first-class medical MOOCs launched on the \'Zhihuishu\' platform. The findings revealed that the number of registered learners (3,240 versus 2,654), questions and answers (27,005 versus 5,116) and students taking the final examination (2,782 versus 1,995) per semester were significantly higher since 2020 compared to these before 2020. Especially, the number of registered learners, registered schools, questions and answers, and students participating in online discussion, taking the unit quiz, taking final examinations and passing final examinations all peaked in the 2020 spring-summer semester. Pearson\'s correlation analysis found that the number of questions and answers and the number of learners who participated in online discussion were both positively correlated with the number of students who passed the final examination, and the correlation was especially strong since 2020. Moreover, the number of publications on medical MOOC research has soared since 2020 and has maintained a continuous upward trend.
CONCLUSIONS: High-quality medical MOOCs have been launched rapidly since the COVID-19 pandemic in China. The number of participants and online interactions of medical MOOCs peaked during the initial spread of COVID-19 in 2020. MOOCs are reliable and valid digital sources that facilitate medical higher education and play irreplaceable roles in emergency management.

摘要：
背景：大规模开放在线课程（MOOC）已成为医学教育中创新的开放学习方法。本研究旨在评估中国2019年冠状病毒病（COVID-19）大流行前后医疗MOOC的构建和应用的动态变化。
方法：主要在中国高教智慧教育平台上搜索2020年前后医学MOOC用法的动态变化，并使用“智汇书”平台的40个国家一流医学MOOC进一步分析了详细的学习概况和结果指标。
结果：从中国高等教育智慧教育平台共输出了2,405个医疗MOOC，其中1313起（54.6%）自2020年以来推出。在2020年COVID-19首次传播期间，141个国家一流医疗MOOC的参与者总数和平均人数达到峰值。我们进一步分析了2018年至2022年MOOCs的动态使用情况，基于“智汇书”平台上推出的40个国家一流医疗MOOCs。调查结果显示，注册学习者的数量(3,240对2,654)，自2020年以来，每学期的问题和答案（27,005对5,116）和参加期末考试的学生（2,782对1,995）明显高于2020年之前。尤其是,注册学习者的数量，注册学校,问题和答案,和学生参与在线讨论，参加单位测验，参加期末考试和通过期末考试都在2020年春夏学期达到顶峰。Pearson的相关分析发现,参与网络讨论的问答人数和学习者人数与通过期末考试的学生人数均呈正相关,自2020年以来，这种相关性尤其强。此外，自2020年以来，医学MOOC研究的出版物数量激增，并保持持续上升趋势。
结论：自COVID-19在中国大流行以来，高质量的医疗MOOC迅速启动。医疗MOOC的参与者数量和在线互动在2020年COVID-19首次传播期间达到顶峰。MOOCs是可靠有效的数字资源，可促进医学高等教育，在应急管理中发挥不可替代的作用。
