I'm a math teacher with future aspirations of teaching at some decent international schools in Latin America and Japan, so I believe I need to get a masters degree. There's one thing I'm very confused about and can't seem to find the answer to: does having a masters degree automatically make you a qualified teacher? Do they have masters programs that come with a teaching credential? I have seen programs for "masters in math education" - does THAT make you a qualified teacher? How can I become qualified to teach math at a good international school? Can anyone recommend any programs? Thank you.
