The Common Ground for Action (CGA) online deliberation platform is a dynamic tool designed to encourage diverse group members to identify collective responses to deeply controversial or "wicked" public problems that have no simple solution. The program promotes authentic deliberation, while minimizing the tactics of horse-trading and negotiating. We detail the structure of the CGA platform, including how deliberative talk is encouraged, outline a sample assignment that can be used with CGA, and professional training offered to faculty and Teaching Assistants.
