新型冠状病毒疫情下生物化学与分子生物学线上教学实践与思考

Practice and thinking of Biochemistry and Molecular Biology online teaching in the context of COVID-19 epidemic

新型冠状病毒肺炎疫情爆发期间,线上教学模式成为教学常态。如何确保线上课程教学质量是全体教师关注的核心问题。课程组紧紧把握“两性一度”内涵,以学生为中心,依靠超星学习通平台构建生物化学与分子生物学课程资源库时兼顾基础型和提高型需求,围绕课前-课中-课后三个环节合理设计教学计划,开展反馈式线上教学,将思政教育贯穿始终,通过案例式思维导图训练和生物化学趣味赛强化学习效果,取得了满意的教学效果。平台数据统计显示,学生学习表现出较好的持续性,95%以上同学综合平时成绩80分以上。本文进一步总结了线上教学的优势与不足,以期为后续线上线下混合式教学的开展与完善提供经验参考。

Online teaching has become one of the most prevalent teaching modes due to the epidemic of2019-corona virus disease(COVID-19). No surprisingly, how to keep the quality of online teaching remains a key concern for all teachers. Inspired by the evaluation criteria of “Golden Course”, our teaching team established a Biochemistry and Molecular Biology online course on Super-Star learning platform considering both the differential needs of regular students and top students, as well as making reasonable teaching planning around pre-class, in-class and off-class. We carried out the student-centered online class by teaching the most important knowledge points in detail based on the feedback from the students who has done the preview work.Further, we designed several case-based mind-mapping training assignments and organized biochemical competitions to improve the online teaching quality. Data from the Super-Star learning platform showed that over 95% of students achieved a comprehensive score of more than 80 points. In addition, we rationally summarized the advantages and disadvantages of online teaching in the aspect of teaching form, learning and teaching supervision and mutual communication between teachers and students, so as to provide college peers reference and inspiration for the following optimization and improvement of online and offline mixed teaching.
