What is an e-Portfolio?

Interesting to see the different definitions of e-portfoilos. I think that the JICS one resonates with me the most:

“Portfolios, in education and personal or professional development, are collections of documents and other objects that can be shown as evidence to support claims a person makes about what they know, what they have achieved, and what they can do. As for eportfolios, a common starting point is that they are simply electronic versions of physical portfolios that contain digital objects instead of physical objects. They are ‘… the new generation of the old three-ring binder’.”

Its quite high level and is therefore flexible, the e-portfolio is evidence of what I know, what ive done and what I can do. Im not too sure how I would evidence ‘what I can do’ surely that feeds from ‘what I know’ and ‘what ive done’. Im also wondering as an e-portfolio is evidence based, is it backward looking element of a ‘personal development file’, whereas the PDP must be the forward looking element?

PDP - a structured and supported process undertaken by an individual to reflect upon their own learning, performance and/or achievement and to plan for their personal, educational and career development.
