Spread the good cheer
I for one would be interested to hear the views of those, Thai or otherwise, who are responsible for EFL programmes in Thailand. On this website we hear from current or former EFL teachers on what is wrong and what should be done about it; there is no shortage of opinion, some of it seems reasonable. In my short experience of TEFL in Chiang Mai I tried to establish a professional dialogue with Thai colleagues who taught English. I suggested, for example, the possibility of exchanging ideas about what vocabulary to teach and how to do so; how we might help one another in classes, for the benefit of students.
I always received a polite response, sometimes a friendly one, but I sensed that my attitude seemed an alien one. Perhaps they would have been more receptive if my suggestions were dropped in casually in the context of a shared meal or social event.
Unless there are meaningful exchanges between teachers/administrators I don't see how small improvements can be made. Of course we always have the option of adjusting our attitude to the status quo, as I found most of the foreign EFL teachers I met to have done.
