I wasn't aware that there were so many sites that provide video clips or on-line lessons. Maybe I shouldn't have been surprised given the explosion in home schooling over the last few years as a knee-jerk reaction to the perceived problems in schools concerning standards of education.
I had come across the TED talks before - however the TED ED was new to me - and I certainly hadn't heard of the Khan Academy.
The above sites are the main ones that I have been checking out. I liked the Khan Academy with its myriad lessons and the challenges. (I confirmed all over again that I am lousy at maths by taking one of the challenges) http://www.khanacademy.org/exercisedashboard
I also liked the idea of designing or constructing a lesson relevant to the teachers needs and then putting it up there to be used or tweaked by others. With students that are comfortable with self-directed learning, this would be great.

My 88 year old mother had been telling me about U3A - University of the 3rd Age - and grumbling that she hadn't been able to find anything that interested her on the website. I suggested that she should check out these sites and see if there was anything there that appealed to her.
Although I cannot see myself using any of them at school, I will more than likely return to them again for my own personal interests. I was happily engrossed in watching a video about Darwin and his ideas on skin colours and genetic diversity when I was interrupted by someone wanting me to work!! I don't think they believed me when I said I was studying.
