In a month-long summer school course, middle school students will design and build an app that will allow anyone to play a city-wide scavenger hunt on their mobile phones. The students will ride bikes gathering digital media that tells stories about their community. They will evaluate and adjust their work plans using a software sprint development model. Throughout the course, students will be given increasingly more control over how they plan their day. By the end, they will run the entire program as a group, without instructor support. The students will learn leadership, teamwork and compassion for themselves and others.
