I was wondering if anyone has any experience teaching English to hospital staff (for them to become conversant with foreign patients)?
I've been teaching this for a few months but the course has been extended to last a whole year. I'm looking to recommend a textbook for this class (and preferably a series - where knowledge builds through 2 or 3 levels) but I've not had much luck with my search so far. If anyone can point me in the right direction I'd be most grateful.
