Abstract: Objective To review and evaluate the effect and learning outcomes of web-based teaching during COVID-19 pandemic and find the pathway of continuous development of teaching method to meet the learners' needs in future. Methods Eighteen questions included time period of web-based learning, effects, advantages and disadvantages of the learning, the willingness of students to accept web-based learning pathway. One hundred and eight medical students completed survey by response to the questionnaires. Results Only 12 students (11%) believed they could get 100% from web-based teaching as compared with face-to-face teaching, while 55 students (51%) believed they could get 80%-99% from their web-based teaching. Thirty-four students (31%) thought current web-based teaching did not bring their learning anxiety, but 30 students (28%) thought the web-based teaching brought their anxiety because of worrying not able to understand the courses thoroughly. Sixty-nine (64%) students would like to take the playback of the courses. The most common factor affecting the effect of web-based courses was absent-mindedness (64%), followed by trouble of internet access (57%). The advantages of web-based teaching courses included: flexible time (85%), freedom of place(83%), more comfortable learning environment (59%) and saving time (56%). Eighty-seven students (81%) were willing to obtain web-based teaching in their future medical learning, and only 21 students (19%) were reluctant to have web-based teaching. The higher the proportion of understanding of online courses compared to face-to-face courses, the more likely they were to choose online courses (P＜0.01). Students who felt anxiety because of worrying not learned thoroughly would not choose the web-based teaching (12/21 vs. 18/87, P＜0.01). Fail to keep concentration at learning was the main reason why students do not like online teaching in the future when the pandemic is over (7/21 vs. 75/87, P＜0.001). Conclusions During on the pandemic of COVID-19, most medical students thought web-based teaching is a feasible way to learn medical courses and can achieve relatively good effect.
