Web 2.0 allows users to create and share dynamic content, moving from a "read only" web to an interactive "read and write" experience. It includes social media sites, blogs, wikis, video and photo sharing. Using these tools in education provides opportunities for students to collaborate, share information, and engage in constructivist learning. Educators should consider their objectives and appropriate tools to achieve them while balancing privacy and security issues. Examples of free Web 2.0 tools discussed are blogs, wikis, YouTube, social bookmarking, and social networking.
