8. Easy alternatives
I don;t have an e-portfolio but I do have a blog, which I've been writing for ten years and a history on social media and files I've securely backed up and stored. All of these mitigate against hte e-portfolio idea as they are my trusted sources.
9. Yes in vocational
There is, of course, a strong argument for e-portfolios in vocational learning, where the learners are being asked to create concrete things that can be stored digitally - graphics, design, photography and so on. We don;t want to throw out the portfolio baby with the bathwater.
