I am amazed that so many teachers are not aware of TED.com. Tagline: Riveting talks by remarkable people, free to the world
It doesn’t matter what subject you teach – there is something there for you. I like it because it is a counter to the compartmentalisation of knowledge which is so endemic in secondary schools.
So what should I recommend? I was going to try to list a few, but that would actually go against the spirit of TED; there is no ‘best’. Simply go to the home page and just browse through a category that interests you. It won’t be long before you get pulled out of your comfort zone.
But keep it a secret; if the powers-that-be find out how incredible it is they may just have to block it.
Last two videos watched:
Dan Ariely asks, Are we in control of our own decisions?
Jonathan Haidt on the moral roots of liberals and conservatives
Think for Yourself 
I discovered Ted just after I left college and I think I learned more after 1 month of watching videos than I did during 3 years of my degree!
That pretty much sums it all up. Isn’t it incredible how so many go through this process called education and learn so little after anything up to 14 years in the system?
