Every Tuesday we bring you a TED Talk on education we find especially thought-provoking. How do we learn best? Where does creativity come from? How can we become a more educated world?

In this talk, child prodigy Adora Svitak says the world needs "childish" thinking: bold ideas, wild creativity and especially optimism. Kids' big dreams deserve high expectations, she says, starting with grownups' willingness to learn from children as much as to teach.
