“What does Web 2.0 mean for education? These tools are changing how people, including our students, interact with the world. The changing nature of information and the new ways our students understand and make sense of the world signal that we need new strategies and new tools for teaching and learning.”
Web 2.0 new tools, new schools by Gwen Solomon and Lynne Schrum


Web 2.0 is organized by using tags. A tag is a word or words that an author uses to describe the information that he or she is sharing. For example, if you are sharing a picture of an airplane, the tag would simply say “airplane.” By typing in this tag name in a search, you would then be able to search all pictures or information with airplanes as a result.
