Exactly, a teacher's role is not that of an entertainer. Being an entertainer which is often expected by Chinese TC owners is the role of a white monkey in a muppet show.

Ultimately an entertainer is more concerned with themselves and their performance whereas a teacher puts their students first and seeks ways to get the most out of them. To do this in the field of ESL a teacher needs to allow his or her students to take centre stage, encouraging them to interact and use the language as much as possible. While a teacher may often provide the initial topic and/or stimulus for a discussion they should also know when to step back, mediate and observe - not the sort of thing most entertainers do in their day to day jobs.
