Ice Breaker is a web application designed to allow students to ask real-time, anonymous questions during class. Once started, it allows the creation of rooms, each with its own set of keys: a private instructor key, and a public student key. Each key exposes a different view of the room; students see only a form that allows them to submit questions (optionally including a name), whereas instructors see a stream of incoming questions from students. The envisioned use of this application is that one of the instructors (most likely a TA) monitors the instructor view during class, and asks any incoming questions by proxy. The hope is that this will lower the barrier for shyer students to ask questions during class.
