  What is Web2.0? Web 2.0 refers to what is thought to be the second generation of web development. Web 2.0 emphasizes sharing, collaborating, and communicating. In Web 2.0, the Web is a participation forum rather than a passive medium The phrase “Web 2.0” was first brought forth by Darci DiNucci in 1999, but is more closely associated with the O’Reilly Media Web 2.0 conference in 2004.

  Characteristics of Web2.0 Search The ease of finding information through keyword search. Links Ad-hoc guides to other relevant information. Authoring The ability to create constantly updating content over a platform that is shifted from being the creation of a few to being constantly updated, interlinked work. In wikis, the content is iterative in the sense that users undo and redo each other's work. In blogs, content is cumulative in that posts and comments of individuals are accumulated over time.

  Implications for TeachingThe teacher surrenders control as the font of knowledge. Rather, the teacher acts as a guardian for appropriate behavior and responsible knowledge. Non-linear curriculum Because student-centered learning of this kind is random, the curriculum will have to be flexible. Staff Development The teachers will have to know the technology in order to manage the classroom.

  Implications for Schoolsand Districts Districts need to foster safe social networking. Currently, most districts respond by blocking most social networking sites. To avoid this, administrators will need to be trained on how to provide safe access to students, and teachers will need training on how to integrate these tools in the classroom.
