ANALYZINGWEB2.0PRINCIPLES FROMALEARNINGPERSPECTIVE The term“Web 2.0”runs danger of becoming a buzzword as empty as “e-learning”: some years ago, every learning software that used the Internet in some way was coined as “e-learning software”, regardless of whether it was innovative or helpful for learning. Today, Web 2.0 faces the same fate: every Web-site with a fancy interface is sold as Web 2.0. However, careful analysis shows that Web 2.0 can be used to describe a new set of software applications that distin- guish itself from previous applications by a number of prin- ciples. While in the beginning of the Internet, software was modeled after the practices prevalent at that time, slowly a new kind of applications emerged. The defining principles of these applications were first captured by O’Reilly [30]. Anderson [6] used a slightly different categorization of what he calls the “big ideas” of Web 2.0 and gives examples of current usages of Web 2.0 services for learning and digital libraries. None of the principles is a new technology or development for itself. As the inventor of the Web, Tim Berners-Lee, points out, Web 2.0 works on the same standards as Web 1.0 [6], and his original vision of the Web was the one of a “read-write-Web”, where everyone could add and edit Web pages [9]. However, taken together the “big ideas of Web 2.0” have reached a critical mass that transforms the way of publishing and information exchange so distinctively that the term “Web 2.0” is warranted. In the following, we will analyze Web 2.0 principles (based on [30, 6]) and analyze each principle with respect to the im- plication on technology-enhanced learning. This will allow us to make general statements about the implications of Web 2.0 on pedagogy based on the inherent technical features of Web 2.0.
