I am in contact with several ex students who are university teachers of English in China and they are currently replacing classes that would have been face to face with online classes. Classes at schools also seem to be interrupted and online teaching is being used through an app called DingTalk - students of mine also refer to Tencent as another platform (Wang 2020).
It will be interesting to see what emerges in terms of a new experience of online learning. Perhaps there will be new innovative practices or possibly students and teachers will feel that online learning is inferior (if it is used badly, this seems possible). I wonder whether researchers will use this as a test case.
In informal chats through WeChat, my ex students refer to problems related to poor broadband speeds or other technical problems and, of course, this is a problem we face at the Open University.
