Many teachers, such as yourself, being experienced, wouldn't need such training; however, clearly JN was referring to teachers who have had no experience and show up on the doorstep of a school without the slightest hint of what to expect or what they should deliver in the way of quality English training. Perhaps you would be best suited as one who provides such training or, at the very least, a few seminars on what you have found works best for you. The downside of the idea, though I think it a good one, is that excess pride often gets in the way; that is, too often a "teacher" simply because he/she is a native speaker carries the false belief that they can provide adequate second or foreign language training when, in fact, that is rarely the case. Moreover, administrators of most English programs in China proceed under the false assumption that because a "teacher" is a native speaker he/she must, therefore, be able to provide English training - if, that is, they're even bothering to concern themselves with that or any other issue beyond the growth of their bank accounts.

Unfortunately, I have no doubt in my mind that things are going to get a lot worse before they get better.
