What is Web 2.0?
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.
Features of Web 2.0
Users run software applications through a browser.
Users own the data on a Web 2.0 site, and control that data.
Data can be shared with other users, who often can add or change that data.
Data can often be embedded in other Web-based software applications.
Characteristics of Web 2.0
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.
Characteristics of Web 2.0
Tags Categorization of content by creating tags: simple, one-
word user-determined descriptions to facilitate searching and avoid rigid, pre-made categories.
Extensions Powerful algorithms that leverage the Web as an
application platform as well as a document server.
Signals The use of RSS technology to rapidly notify users of
content changes.

Web 2.0 and Education
Implications for Learning
Democratizes Learning Students are now responsible for researching,
generating, sharing, and modifying content.This means that there is no single source of
information, whether it be the teacher or the textbook.
Constructivist The very nature of these media makes learning a
constructivist experience. Information and processes are relevant and authentic
in today’s digital world.
The Digital Natives are restless. Leave Me Alone….I’m Socializing
Implications for Teaching
The 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 DevelopmentThe teachers will have to know the technology in
order to manage the classroom.
Implications for Schools and 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.
