The above presentation, recently produced by JISC RSC Scotland South & West is an excellently crafted document which clearly articulates present thinking and concerns relating to ePortfolios. Click here to see for yourself.
However, yet again, this author appears to believe that the whole content delivery system, learning management and assessment, CPD and showcasing can all be crammed into what is essentially a private and learner-owned tool. As I tried to make clear, several years ago, (Who's Hijacking My ePortfolio - best read in Full Screen mode) institutions have their own individual agendas and appear to expect the ePortfolio to do all the conventional tasks of a VLE but without the expense! Admittedly, some VLEs are expensive as are assessment tools, plagiarism checkers etc.
As regular readers will know, one of my pervading mantras is "Let the VLE do what it does best and leave the ePortfolio to do what it can best do."
But, again, let me say, a good presentation which is worthy of further discussion.
