Social media and Web 2.0 tools are changing the way we teach and learn. These tools allow for greater accessibility, immediacy, and interactivity in communication. Over half of online youth ages 12-17 use social networking sites like Facebook and Twitter, primarily to connect with friends and meet new people. Tools like YouTube, microblogging on Twitter, Google Apps, Wikipedia, and social bookmarking have implications for teaching and learning by engaging students, facilitating collaboration and sharing, and developing skills like visual literacy, research, and information literacy.
