This article reports on an urban living laboratory that designed a suite of play-based prototypes, as an attempt to “institution” collaborative smart city governance in the city of Boston. This project was called “Beta Blocks,” and it geographically defined “Exploration Zones,” governed by local residents and business owners, who decided whether, where, and why to temporarily install technologies in the public realm. To recruit and facilitate the participation of Zone Advisory Group members, the authors fabricated a lavender, parking-space-sized, inflatable art exhibition (Beta Blob) that hosted a suite of public-facing activities. Although the composite model failed at “institutioning” itself into Boston’s government through this prototype, the discrete components succeeded in centering play in public learning situations and prototyping a model for collaborative governance between publics, and the public and private sectors.

We present a tablet-based system to collaboratively track discussion topics and ideas in a seminar-style discussion classroom. Each student uses his or her own tablet to share text ideas in a synchronized, visual environment. The system is designed to promote diverse participation and increase engagement. Our findings are based on observations of twelve class sessions and interviews with participating students. Instead of simply introducing an additional text-based communication channel into the classroom, we find that the system creates a new "stage" (in the Goffman sense) on which students could perform in ways that the main spoken stage could not support. This stage coexists with spoken communication, and augments how students attend to the material and each other. We conclude that spoken participation alone poses barriers for some participants and the addition of a non-oral, text-based stage can help establish equitable and engaging discussions in the class.
