Abstract: Objective    To explore the application of online teaching based on internet in the course of abnormal human morphology experiments during COVID-19 epidemic. Methods  The undergraduates majoring in stomatology, Traditional Chinese medicine and prevention of Capital Medical University were selected as the subjects of the study. The students in grade 2018 were selected as the experimental group and the students in grade 2017 as the control group. The experimental group adopted online self-study + live teaching + online evaluation, while the control group adopted traditional teaching methods. The final examination and questionnaire survey were used to evaluate the effect. Results   In the experimental group, 86.49% of the students were satisfied with the effect of online teaching and learning. The average scores of the final multipile choice question examination based computer were 75.81 ± 11.88, and the difficulty index and the coefficient of discrimination of the test paper was respectively 0.7581 and 0.2767. The average scores of the final digital slices diagnosis examination were 95.34±9.04, but the difficulty index and the coefficient of discrimination of the test paper was respectively 0.9534 and 0.1581. Conclusion  The online teaching mode of abnormal human morphology experiment based on internet is recognized by students, which improves students self-learning ability and has good teaching effect. The method of online multipile choice question examination computer-based is feasible for abnormal human morphology, and the method of online digital slice diagnosis examination needs to be further improved.
