TED will need no introduction for some people. If you are one of those who has enjoyed a TED talk in the past, go and get this free app and have TED talks streamed or downloaded onto your iPad for those moments when you are stuck on a train, waiting at the dentist or just need some inspiration. If you have never heard of TED, then go and get this free app and find out what you have been missing!
The app also allows you to search and bookmark talks, and has a few other nice tools too.
For me, TED is a great antidote to the average newspaper as it tells inspiring stories of people doing great work in all sorts of ways. There are TED talks that you might want to share with your students.
If you are really interested, you might even want to go and visit TEDEd, TED for Education, which helps you build lessons around TED talks.
If you want to see the format of a TED talk, this talk published one month ago, give you an idea of how they work.
