Transnational online education in biochemistry during and after the COVID-19 pandemic in Binzhou Medical University: challenges, strategies and outcome.

Background: Due to the global outbreak of the COVID-19 epidemic, schools were forced to shift teaching from face-face to online. During this period, a large number of studies on how to better carry out online teaching emerged. However, these studies were basically conducted with domestic students as teaching objects. The research on transnational online education conducted by overseas students is very limited. Methods: We first conducted a questionnaire survey on the obstacles of transnational online learning of 64 international students from our school who were staying abroad at the beginning of the fall semester of 2020, analyzed the results using the two-tailed student's t-test and changed the teaching platform accordingly and compared the results of the biochemistry exams conducted for 2018 spring class with those of 2018 fall class and the 2019 fall class, so as to verify the superiority of the DingTalk as a transnational online education platform. Results: The results showed that the main difficulties of overseas students in transnational online learning are poor network conditions and time difference. By using DingTalk as an online teaching platform, these difficulties were overcome. In the spring class of 2018, the results of online study students' biochemistry were significantly lower than those of students in face-face study (t-test, p = 0.01). However, after the switch to the DingTalk platform, online students' results in the 2018 fall class (t-test, p = 0.35) and the 2019 fall class (t-test, p = 0.7) were equivalent to the academic performance of face-face students. Conclusion: Our exploration and application of DingTalk software in transnational online education successfully solved the dilemma of overseas students' online learning, and provided a feasible method to guarantee the efficacy of online teaching.
