Having recently returned to England (where I am an Open University tutor) after having spent about 18 years teaching Physics and Astronomy at the University of Nigeria at Nsukka in the Eastern part of Nigeria, I find myself in an unusual position to understand the difficulties of teaching such a rapidly changing subject as astronomy in an isolated place like Nsukka. For example I have seen a great contrast between the OU Astronomy and Planetary Science course material and the few available text books at Nsukka. Although not very mathematical, the OU material includes a lot of the latest research results and theories, whereas at Nsukka the books have hardly changed in the past 20 years.
