Evaluation and perception of online teaching of molecular biology using DingTalk for international medical students during the COVID-19 pandemic.

The COVID-19 pandemic has greatly impacted the education of international students. The authors taught a molecular biology course using the DingTalk platform for international medical students (IMS) in the autumn semester of 2020. We assessed the effect of this online teaching based on an online questionnaire and by analysis of the final examination scores. Our findings demonstrate that the DingTalk platform is a free, effective and convenient online teaching tool for international students. The students' feedback showed that most of them were satisfied with this live teaching with DingTalk. They considered who viewed that the questions used in the live classroom setting were helpful for their learning. There is nonetheless still scope to improve this online teaching mode for international students, such as providing more pre-recorded teaching videos for offline application and use of a virtual simulation experimental molecular biology course. We hope that our findings regarding the experience of IMS with this teaching mode will be of value to other academic faculty.

The impact and evaluation of COVID-19 pandemic on the teaching model of medical molecular biology course for undergraduates major in pharmacy.

Molecular biology is a very important basic course for undergraduates major in pharmacy. During the novel coronavirus epidemic, we first adopted an online teaching of molecular biology course with rain class and tencent meeting for undergraduates major in pharmacy, following a blended teaching mode. Finally, we evaluated the effect of this special-time teaching by analyzing the anonymous questionnaire and final examination scores. Student feedback showed that most of students were satisfied with this online teaching, classroom teaching, and experimental teaching, and considered that postlecture quizzes were very helpful for their study. The majority of students supported that classroom teaching should be integrated with online teaching. Analysis of final examination scores showed that the effect of 2020-year teaching was not worse than that of 2019-year teaching, but even better in the excellence rate and rate of poor and failure. Here, we share the experience and thinking of blended teaching of medical molecular biology course during the novel coronavirus epidemic, and hope it helpful for other teachers' teaching.
