How I Use It
There are some great videos here including 'The Unexpected Math Behind Van Gogh's Starry Night' - and others as well. I use these both as lead ins to discussion with my students on a broader topic and as 'emergency sub lessons' - sub can show one of these videos and then students can write or record a reflection either on their laptops or in their sketchbooks. A lot of these need to be 'teacher led' as they introduce concepts that students may not understand without teacher introduction or teacher led discussion afterwards (or both).
This is a great start of what can be done with TED videos but there are unfortunately very few video choices here and some of the most famous TED talks on the arts are noticeably absent (including Phil Hansen's 'Embrace the Shake' and Sir Ken Robinson's 'How Schools Kill Creativity'. The videos that are here are great choices as 'starters' for lessons and deeper discussions about the arts for both students and teacher.
