My student teacher was able to get the kids outside for a little geocaching in order to prepare for the AP test in a unique way.
He and I spent the morning typing up personalized examples of literary devices they seemed to be struggling with. Each of the samples featured one of the students. We hid them outside all over campus in sandwich bags, making sure to plot each of their locations with device.
Students spent their mornings finding each of the literary device clues. Once they found one, they used their iPhones (or iPod Touch) to tweet the example and notate which of the literary devices it was. This kept all the groups that were spread out around campus truly "connected" to each other as they all were posting to and reading from the back channel.
