Here, in New Zealand, we have many schools (primary and secondary) who are using ePortfolios through MyPortfolio.
An ePortfolio can be used as an online collection of reflections and digital Artefacts (such as documents, images, blogs, resumés, multimedia, hyperlinks and contact information). Learners and teachers can use an ePortfolio to show their skills, their learning and their development. These can then be shared with a selected audience.
An ePorfolio allows the learner to build reflective activities through blog functions and the creation of diaries in which users can reflect on their learning and experiences over a given time frame or activity. This can then become a two way process with a teacher or peer providing feedback via the same diary.
