During the COVID-19 epidemic, many countries faced a critical situation in terms of the global economy and human social activities, including education. In China, the coronavirus is better controlled. Chinese university students have returned to school to study. Despite previous research on online education and learning, the readiness of students for the online and offline learning models implemented at this particular time is not well understood. This paper discusses a hybrid education model for undergraduate students in the safety engineering major. Questionnaires are administered to faculty and students from different colleges and universities in the same major to statistically summarize the influencing factors of mixed or hybrid education. The system dynamics (SD) model is constructed and simulated to determine that using online in the tenth to fifteenth, twenty-fifth to thirtieth, and fortieth to forty-fifth min of classroom teaching (50 min in total) can effectively increase students' interest and engagement in learning. More hands-on activities should also be considered to enhance students' motivation to acquire knowledge, and consideration could be given to encourage interaction among students. This study will be continuously improved by a follow-up study of undergraduate student performance. This study has important implications for educators implementing online and offline blended instruction.
在 COVID-19 疫情期间，许多国家的全球经济和人类社会活动都面临着严峻的形势，教育也不例外。在中国，冠状病毒得到了更好的控制。中国大学生已经回到学校学习。尽管之前已经对在线教育和学习进行了研究，但学生对当前实施的在线和离线学习模式的准备情况并不清楚。本文探讨了安全工程专业本科生的混合教育模式。我们向不同院校的教师和学生发放了问卷，对混合教育的影响因素进行了统计总结。构建了系统动力学（SD）模型并进行了模拟，确定在课堂教学的第十至十五、二十五至三十和四十至四十五分钟（共 50 分钟）使用在线教学，可以有效地提高学生的学习兴趣和参与度。还应考虑增加更多的实践活动，以提高学生获取知识的积极性，并考虑鼓励学生之间的互动。本研究将通过对本科生表现的后续研究不断改进。本研究对教育工作者实施在线和离线混合教学具有重要意义。
