In the third wave of computing, people will interact with multiple computers in multiple ways in every setting. The value of ubiquitous computing is enhanced and reinforced by another trend: the transition to a Web 2.0 world. In a Web 2.0 world, applications and data reside on the Web itself.

However, students are increasingly gaining access to computers outside of school. In this article, the author discusses how schools can be enhanced in the era of Web 2.0 ubiquitous computing.
