While I'm really happy to see that someone is publishing a desperately needed book -- their forthcoming Teaching EFL in China: What Every Foreign Teacher Should Know Before They Go -- I'm disappointed to see that a) it is not being published by a reputable academic publisher and b) at first glance it does not appear to be substantially revised from the previous articles they have put up on their website.
Niu and Wolff are saying some really important things about a really important sector of global ELT, but their work frequently comes off as recalcitrant and unrealistic. I don't mean to be harsh, but hope their new book(s) will prove to be otherwise.
