Through the process of partnering with a community organization and working in the context of in real-world challenges, students will explore and practice techniques for at-scale change through the social lab. In this second part of the social lab, after the challenge has been identified, students will focus on prototyping small-scale responses while evaluating from an at-scale perspective keeping in mind goals and metrics identified from the previous semester. Together with our partner, students will learn to apply emerging IxD craft and process skills to engage partners through group processes. Equally important, students will use their emerging reflective skills to identify the work to be done in the context of this challenge. During the semester students will develop a more focused response, as well as a pitch for funding to run their challenge at scale during the summer semester. Finally students will deepen their understanding of how to move through personal, group and lab issues in the context of the social lab.
