The challenge was to "Design an iPhone app that is useful to our school community." I used a challenge-based learning approach to inspire a group of beginning programmers to design questions, conduct guiding activities and find the resources they needed to invent a solution to a campus-wide problem. Along the way, I documented their thinking and used video and online tools to capture the story of how our app was published on the App Store and how this process transformed our classroom into a student-centered, fully collaborative learning environment.
