I first discovered TED Talks when I was convalescing from my ski accident almost 2 years ago. They're usually good for stimulating thought; on the other hand, sometimes they project that NPR-like elitist veneer. That's not to say that I wouldn't enjoy attending one some time, just that not every word spoken in them is gospel.
I was watching some of the videos last night and these two interested me. Under the new Common Core standards, the first video should generate many huzzahs and accolades. The second just makes sense to me. (full disclosure: I teach stats)
