If educators want to discover how they can engage students as well as themselves in the 21st century, they must move beyond skills and technologies. They must explore the interconnected social media literacies of (1) attention; (2) participation; (3) cooperation; (4) network awareness; and (5) critical consumption. In this article, the author focuses on these five social media literacies. He argues that the most important fluency is being able to put all five of these literacies together into a "way of being" in digital culture. Just as the print technologies and literacies shaped the Enlightenment, the social media technologies and literacies will shape the cognitive, social, and cultural environments of the 21st century.
