After all, for that term with his students, he is not there to entertain them

Really? Haven't you heard of 'Raoul's white monkeys'?Unfortunately,at many Chinese educational institutions such as kindergartens,junior middle schools,senior middle schools and colleges,students expect to be entertained by their FT's.The trouble is the Chinese education system has given its students the power to choose their teachers by allowing them to fill out forms assessing the teaching.Oftentimes,clueless FT's who promise their charges that no-one will fail will be popular with students,while strict FT's who try to make students work hard will be given low marks.Apart from at the more prestigious Chinese educational establishments,which are relatively thin on the ground,by the way,being an entertainer is more important for an FT than being able to impart useful knowledge,I'm sad to say.So,what's the point of learning to teach well?Much better to learn how to entertain them by clowning around and playing games in class.
I get the impression you don't realise how bad the education system here is.I think it's in a dreadful state.
Those talented Chinese who get top grades do so in spite of that!
