Well, in Thailand English teaching and learning problems cannot be solved by employing the "native speakers". As mentioned earlier, Switzerland, and many other European countries where teaching and learning English is a big success, do not rely on what my colleague Dr. Sorin, call as "na (t) ive" speakers but on their own teachers of English.
In Asia, a good example is India. Although colonized formore than two centuries India does not employ foreigners to teach English. Yet, it has a huge population that can speak and write English. It has grown its own crop of English teachers. They are all graduates of Indianuniversities majoring in English. Singapore and Malaysiaalso followed the same model. It created its own pool ofexcellent English teachers.
If the Thai Ministry of Education is genuinely interested in improving English education, then they have to do the following:
Improve the quality of Thai English teachers. The teachers of English have to be good; they have to be aninspiration for their students. It would be very natural for young Thai students to say "if my teacher could do it, I can do it too". A white hillbilly native speaker from Texas, USA without a degree in English literature can never be an inspiration for Thai students.
