This document discusses social media and its uses in education. Social media includes tools like Twitter, Facebook, blogs, and YouTube that engage users in conversation. For education, social media allows for connecting, networking, influencing, marketing and administration. However, there are also challenges like age restrictions, cyberbullying, stranger danger, and teachers' dual roles.
