I thought some faculty might enjoy this Sloan-C Webinar on e-portfolios. (If you don't have the software already loaded, it will load automatically; just keep clicking "allow" and "OK" as needed! There is audio overlay to the slides, so make sure you have speakers or headphones.)
I can't think of any discipline in which it wouldn't be both prudent and educational for a learner to produce an e-portfolio. There are lots of resources out there as well as innovative applications of the tools. I'll create a special e-portfolio section of this blog page for linking you to the latest and greatest in e-portfolios.
