This report presents findings from a two-year investigation of the ways in which Web 2.0 tools and social networking technologies are being used to support teaching and learning in classrooms across the United States. With funding from Intel®, the Education Development Center's Center for Children and Technology (EDC/CCT) interviewed or visited over 30 educators in 22 different schools throughout the country as they employed these tools in their classrooms in innovative ways. We also spoke with and observed a number of students in these schools. Currently, there is much discussion and excitement about Web 2.0 in education, but we still know very little about how these tools actually work in the classroom. Therefore, the goal of this research was simply to interview and observe educators and students who are experimenting with these tools in the classroom to see what uses are emerging and to explore the learning affordances of blogs, wikis, and other Web 2.0 tools.

Web 2.0 describes World Wide Web sites that emphasize user-generated content, usability, and interoperability. The term was popularized by Tim O'Reilly and Dale Dougherty at the O'Reilly Media Web 2.0 Conference in late 2004, though it was first coined by Darcy DiNucci in 1999.[1][2][3][4] Although Web 2.0 suggests a new version of the World Wide Web, it does not refer to an update to any technical specification, but rather to cumulative changes in the way Web pages are made and used. A Web 2.0 site may allow users to interact and collaborate with each other in a social media dialogue as creators of user-generated content in a virtual community, in contrast to Web sites where people are limited to the passive viewing of content. Examples of Web 2.0 include social networking sites, blogs, wikis, folksonomies, video sharing sites, hosted services, Web applications, and mashups.[5] Whether Web 2.0 is substantively different from prior Web technologies has been challenged by World Wide Web inventor Sir Tim Berners-Lee, who describes the term as jargon.[6] His original vision of the Web was "a collaborative medium, a place where we [could] all meet and read and write".[7][8] On the other hand, the term Semantic Web (sometimes referred to as Web 3.0)[citation needed] was coined by Tim Berners-Lee for a web of data that can be processed by machines.[9]

Teacher educators are constantly revisiting and revising their teacher education programs. Historically, research, educational policy, and accreditation requirements have been the impetus for renewal in teacher education. For the past 20 years, technology innovation has played an increasingly significant role in rethinking teacher education. This paper discusses recent changes in a social studies teacher education program and the role Web 2.0 tools played in helping to rethink pedagogy.

What is Web 2.0? A simple definition of Web 2.0 is the “Read/Write Web.” Originally, the Internet was a place to locate information - mainly a "Read Only Web." As the Internet slowly changed, web sites were developed that let people "write," collaborate, and share information, such as Wikipedia and Facebook.
