A few people have been asking about the free on-line education links I mentioned earlier, so I thought I would post them
www.saylor.org is the site that has impressed me the most. It is basically a "free" online version of an undergraduate US degree which people can work through. I am not sure how it stands up from a credits POV, but if you are simply interested in a subject and want to learn more about it, it is a very good resource. I've been looking at the History module and worked my way through the 1st unit and was impressed by the links. Am going to have a look at the Greek Civilization module next. There are modules in the History section that cover all major periods.
They also cover majors such as English Lit, Political Science, Biology etc. I had a quick look at the biology module and it was decent. If you are studying any of these areas, this site may have some helpful links
http://openlearn.open.ac.uk/ is a link to the Open University free section. There are links to short courses. Basically, these are short selections from the fee-paying modules. Some of them are very interesting and worth doing, but others (introduction to classics) are simply a teaser to try and get you to sign up to the full module.
http://www.openculture.com/freeonlinecoursesThere are a whole load of openware courses from top universities in the US now available online. Most of these are in the form of videos of the lectures. These include courses from MIT, Yale, Harvard etc. The above link lists most of these under various subject headings.
http://www.onlinecollege.org/2009/05/27/100-free-courses-to-teach-yourself-world-history/is a link to History courses. These vary in whats available. This course from Yale on Ancient Greek History has been recommended by loads of people. It is very comprehensive and has both videos and transcripts of the lectures
