Helen Barrett's home page on eportfolios for learning. She includes a keynote address she did on portfolios for an educators group in Hamilton, NZ in February 2015. Lots of excellent individual slides on lifelong learning and how the portfolio is a laboratory.
Excellent exploration of a PLE and how it may or may not integrate with a formal institutionally based and managed VLE (through a school or employer perhaps?) and how the learner needs to own his/her PLE for lifelong and portable learning. Acknowledges the eportfolio that a school might provide a learner (but this can be set up and managed by learner as a formative and summative device).
GOOD INFO: This web page provides information on common software tools available on personal computers and/or the Internet to facilitate assessment FOR learning in electronic portfolios.
nice explanation of how professor uses email, scanner, Evernote, and Dropbox to build a fully searchable portfolio to organize and store bits of information that need to be compiled when being considered for tenure.
