Is it just me or have TED talks dipped in quality over the past few years? Seems like you need to go through a couple before finding the really good ones. I sincerely enjoyed this one about a teacher who designed a special game for nine year olds to help them understand how the world operates. It sounds like an amazing class and formative experience but I just wonder what it must be like to be the teacher who gets these students the year after. John Hunter sets the bar high.
