目的：分析眼科学线上教学所面临的问题，并分析其中原因。

方法：调查时间为2020-05/06。采用自行设计的调查问卷及成绩对比的方法。问卷调查包括课前课后用时、线上教学面临的困惑和教学效果自评等。调查对象为63名五年制本科学员和眼科学所有带课教员。

结果：学员线上和线下教学课前平均用时接近，但教员线上课前用时明显长于线下教学。63%学员认为线上教学课后复习需更长时间，95%学员承认线上教学因缺乏互动而走神，73%教员因缺乏互动而影响激情。73%的教员预计线上教学效果会差于线下教学，但95%学员认为通过重复观看视频，知识掌握无明显差别； 线上教学最终成绩与往年同类学员线下教学无差别； 91%教员和79%学员推荐录播与直播相结合作为未来的线上教学模式。

结论：缺乏互动是影响线上教学效果的最主要因素。线上教学效果与线下教学类似，但课后所需复习时间更长。录播与直播相结合是师生推荐的线上教学方式。

METHODS:A self-designed questionnaire survey and result of examination comparison were used. The contents of the questionnaire include the time used before and after class, the confusion faced by online teaching and the self-evaluation of teaching effect. 63 students and all teachers were participants in the questionnaire survey. The survey is from May 2020 to June 2020.

RESULTS: The average time spent by students before class of online teaching had no difference with that of offline teaching, while the average time spent by teachers for online teaching before class was significantly longer than that for offline teaching. 63% of the undergraduates considered that online teaching takes much more time to review after class. 95% of the students admitted that online teaching was easier to lose concentration because of lack of interaction with teachers, and 73% of teachers though that for online teaching they had less passionate compared to off line teaching. Regarding to the questionnaire survey, 73% of the instructors expected that the effect of online teaching would be worse than that of offline teaching. Surprisingly, 95% of the students thought that there had no significant difference in knowledge mastering between online and offline teaching after reviewing of courseware. For the future teaching model, 91% of the teachers and 79% of the students preferred the combination of watching pre-recorded video and live broadcasting.

CONCLUSION: The lack of interaction is the primary issue of online teaching. Online teaching can achieve the same effect as offline teaching,whereas it needs more post-class time for students. The combination of watching pre-recorded video and live-broadcasting is the online teaching mode recommended by teachers and students.
