Kindergarten here at English Village is based on total (or as close as you can get while still living in Korea) immersion into the English language. From the moment they arrive until the moment they leave the kids do not speak Korean. They talk to all teachers in English, they study through English they even play through English and it works. Kids are like sponges and they pick up and use new words at an amazing speed. It is very rarely now that I have to put on my teacher voice and say "Don't speak Korean". Ok, they forget at times or don't know a word so use the Korean but apart from that, English.
To be able to speak English for Koreans is a major advantage. Most, if not all, major companies have English proficiency tests as mandatory requirements during the hiring process. With this in mind it is no wonder that English language teaching jobs are so readily available in Korea. English Village is a popular choice as it is not just an hour or so of English classes a day but all classes being taught through English, but because of this it's expensive. Most of my students have parents who are doctors or own their own businesses, etc. The downside to the exclusiveness of our school is that many people from the area just wouldn't be able to afford it and thus we have to advertise a lot.
The enrolment for next term is beginning shortly and so once again the advertising is in full blast. This term they decided an online "preview" of our school would be a cute idea too so we all had the pleasure of a camera filming our classes while we taught one day a few weeks ago and here is the final product:
