I'm guessing that your initial course was at Certificate level or maybe a taster before the actual Cert. That's really why I asked the question in my earlier post.
For people who wish to get observed teaching practice, I normally suggest finding a willing colleague. It helps if the colleague is more experienced or more qualified than yourself but less experienced colleagues can also make excellent comments and contributions. I'm afraid I don't know how you can get observed teaching practice if you are isolated. The only thing I can suggest is talking it over with a teacher of any subject; is there anybody else at all? Another good way to learn about teaching is to sign up for a course in any subject at all. You'll learn by observing your own teacher. Recently, I've learnt Spanish, singing and self-defence and I learnt something about teaching from all of my teachers. But then you said you don't have time...
The only other thing I can say to somebody who is isolated and doesn't have time is to keep in touch with sites such as this. Maybe write in again when you do have some time.
