In Peer to Peer University we believe that the design of a Challenge should encourage peer learners to get a deep understanding of big ideas that go beyond mere facts.

To complete this task we want you to ask yourself; what is the big idea -- the really big idea (!) -- for this challenge? What do you want your peers to understand? For example "I want them to understand that the web is a system of interrelated parts". Think of something beyond the content, that your peers will remember after say a years' time has passed.
