I'm an English teacher in Japan, working at a small, private school. Part of the job is creating new possible classes that would be interesting and fun for students. I had the idea of building a class around American TV shows. I'm sure I could handle the logistics of it
Today while the public schools (generally) continue to teach English by translation, grammar rules and endless testing, many of the private English schools (not the test-preparation "cram schools") use the English only method.
