English Village is a set up inside a designated public school for area schools to bus their students in to attend English-only programs throughout the year.
Some of them, like the English Wonderland in Chayi, are sleep-over camps where the students come for three days/two nights, but I think most of them are day programs, with the students coming two or three days at a time.
I don’t think it’s so much a variant of public schools so much as they try to hire FETs (who are public school teachers) to be the teachers so that the county governments have bragging rights about having foreigners in their classrooms.
If you apply to be an FET and you don’t specify that you won’t work at an English Village, you could get stuck at one, but most FETs just work at regular public schools and not English Villages. Some counties, however, have “English on the Go”, which, as I understand it, is a traveling English classroom with a similar concept to EV. The difference is that the FETs who have run it these past few years seem to have had total control over their curriculum and can do whatever they think needs to be done to make things run smoothly. Though they have had some things to say about that too…
The public school I currently teach at has an “English Village”, but it’s really just two classrooms with a lot of “fancy” computer and other tech equipment that they spent a few million dollars on back in the early 2000’s and never used ever. (as you can imagine, the students’ phones are more engaging than anything in that room). Every once in a while, they ask me to create a curriculum for it, but when I ask them who the target students will be, they can’t give me an answer and they don’t bother asking me for another few months. In three years, I’ve never gone in there for any reason beyond curiosity.
If you’re fresh off the boat, they might try to get you to do English Village, but, as I said before, I think most counties make the Fulbright ETAs do it because enough FETs have pointed out the worthless waste of time that the whole concept is and have enough pull (a teaching license, for example) that they can get themselves into a better teaching situation.
tldr: traditional public schools are exactly what they sound like. English villages are located within some public schools featuring short “immersion camps” with themed classrooms where you teach the same thing every day to different groups of kids.
edit: I know Fulbright ETAs teach in traditional schools 4 days a week and English villages one day a week, so it’s possible that’s what FETs used to be expected to do but there was enough feedback that FETs no longer have said responsibility.
