The Flourish project:

Flourish, funded by the JISC, looked at eportfolio for HE staff in annual appraisal, accredited PGCert in Teaching in HE course, and CPD/Training. They used PebblePad in a “low-risk” environment running workshops, elearning retreats, staff information sharing channels, and using it with students.
The key message is if you want to use an eP for students you need to use it with staff first.
