With the rapid development of digitalization, online teaching is no longer a supplement to on-site courses but maybe one day become an essential way of acquiring knowledge. For teachers, the changes lie not only in where but also in how to deliver the knowledge effectively. In this session, based on the speaker’s practical experience in online teaching, we will present case studies on interactive online classes and dual-teacher classes. In addition, we would also like to share the application of Wacom in live teaching with some typical cases and its potential opportunities.
