This chapter emphasizes social spaces promoting citizen co-creation of their shared social and political worlds as being essential to support meaningful democratic civic learning. It focuses on direct citizen participation and the need for the open exchange of ideas, opinions, and differences. The analysis presents traditional conceptions of the public sphere alongside new conceptions, such as counterpublics, migrating publics, ephemeral publics. Three examples of institutionally structured civic participation—participatory budgeting, deliberative polling, and citizen assemblies—are examined. By creating environments that facilitate civic participation, public spheres provide spaces where individuals can gain practical knowledge and agency, thus translating learning into long-term civic learning.
