As Web 2.0 technologies impact the evolution of online learning, they are certain to blur the definitional lines between electronic portfolios and personal learning environments (PLEs). According to Gary Brown, director of Washington State University's Center for Teaching, Learning, and Technology, the Web 2.0 technologies that are emerging now--technologies that incoming students increasingly use to organize their personal lives--are changing what people think of as an ePortfolio. Mashups, for example, allow students to combine web-based applications and resources into something new that they own themselves and can make available to anyone. Brown's aversion to definitions notwithstanding, right now PLEs can be loosely defined as systems designed to hand off much of the control and management of the learning process to the learners themselves. Through PLEs, students set their own learning goals, track their own progress, select and organize their own learning content, and interact with peer students and others across the campus and the globe. Here, the author discusses the evolution of Web 2.0 and the ePortfolio, as well as the link between ePortfolios and PLEs. While ePortfolio and PLE users experiment, and visionaries prognosticate, the eLearning product vendors are not quite sure where Web 2.0 is taking the ePortfolio. No matter: They're forging ahead and adding Web 2.0 capabilities to their offerings, in anticipation of "whatever" may come next. The author discusses what comes next on the ePortfolio horizon.
