Online environments are now central to political life, especially for young people. They are prominent contexts for activities that include: fundraising, political debate, sharing political perspectives, mobilizing individuals and groups to act, and applying pressure to governments, corporations, and nonprofits. Much of this online politically focused activity occurs within a broader media ecology that can be characterized as a participatory culture (Jenkins, H., R. Purushotma, K. Clinton, M. Weigel, and A. J. Robison. [2009]. "Confronting the Challenges of Participatory Culture: Media Education for the 21st Century." Occasional Paper on Digital Media and Learning. Chicago: John D. and Catherine T. MacArthur Foundation). Many have argued that media literacy efforts are needed for youth to fully leverage these digital opportunities, but rigorous studies of such educational efforts are just beginning to emerge. Drawing on an original panel survey, this paper examines whether efforts to promote digital engagement literacies increase youth online engagement in politics. We find that they do. Educators' efforts to foster digital engagement literacies increase youth engagement in participatory politics and in applying targeted political pressure to government, corporations, and nonprofits.
