Youth create a social issue video and post it on YouTube. After a tweet, retweets, and more tweets, the video goes viral. That issue that youth care about is suddenly all over the net and receiving broad traditional media attention. With a simple click of the mouse, youth voices are being heard—loudly. What's going on? This webinar is a discussion of the research and practice of youth civic engagement and what participatory cultures and social media mean for youth programming, civic engagement, and leadership. Youth engagement in participatory cultures brings a new approach to addressing long-standing civic and social issues. This non-traditional civic engagement format has youth using new media to organize, to create content, and then to circulate that content around the world—click activism.
