Abstract: The teaching mode of universities has changed greatly after COVID-19 epidemic than before, leading to the adjustments and changes of the direction of teaching supervision. The combination of online and offline teaching will become the new format of college teaching in the post-epidemic period. The rapid promotion and popularization of the combination of offline and online teaching brings new challenges and opportunities to the teaching supervision in universities. In the traditional teaching mode in the past, teaching supervision played an important role in the supervision, inspection, guidance and evaluation of teaching activities, teaching procedures and teaching principles. As the important part of the teaching quality control system in universities, the teaching supervision should consider their new position and how to improve their ability and what function they should play, which needs constant discussion and deep thinking.

Key words: teaching supervision, online and offline, quality control
