Industry analysts say the systems have reached a mature adolescence, having grown from mere electronic filing cabinets into multimedia platforms that can operate with a variety of e-learning tools. Their fullest potential still lies ahead. This article talks about electronic portfolios--better known as e-portfolios, and how e-portfolios are taking on new capabilities by integrating with a range of other e-learning technologies. E-portfolios were among a handful of maturing educational technologies that have cleared the fin and are now heading, slowly, toward mainstream adoption. The sexiest e-portfolio enhancement of the moment is social networking technology (blogs, wikis, IM, etc.). Helen Chen, research scientist at Stanford University's Center for Innovations in Learning, has been investigating how social networking services, such as Facebook and MySpace, might help e-portfolio developers evolve their systems to better serve the digital natives who use them. The author presents a sampling of some of the major providers of e-portfolios that are jostling for position in the marketplace.
