Has the wave of the open web crested? What does "open educational technology" look like, and does it stand for anything? In this article, the authors discuss the rise of open educational technology. The present range of Web 2.0 service providers offers a self-evident strategic technology framework. Without much effort, online teachers and learners can quickly assemble dynamic, networked personal learning environments simply by adopting the most popular tools in any particular domain. There are simply too many applications of open-source software, open content, and public-service teaching and learning practice. The authors present outlines of two of their favorite examples of open educational technology. More-detailed descriptions, as well as interviews with the practitioners, are available online (http://www.educause.edu/er/LambGroomCaseStudies). (Contains 23 notes.)
