Includes a google app about this
http://nickrate.com/2010/12/13/dimensions-and-dashboards/
Includes a classification:
Dimension 1: The Dedicated
A dedicated eportfolio system such as Mahara.
Dimension 2: The Managed
The eportfolio functionality or module built in or attached to a learning management system such as UltraNet, KnowledgeNet, Moodle etc.
Dimension 3: The Blogged
ePortfolios that are contained within an online tool such as Blogger, WordPress, Wikispaces, Weebly etc.
Dimension 4: The Mashed
An eportfolio that is not contained in any one place. It draws on the functionality of several online spaces and web technologies, using the best features of those tools to create and share learning. An example could be this netvibes dashboard.
Dimension 5: The Saved
ePortfolios that are created using desktop software and are not online. They are typically shared after being saved to a disk. Common software for this includes PowerPoint, Keynote, iWeb etc.
Dimension 6: The Integrated
ePortfolios that are seamlessly integrated into the way students are learning. It is a direct reference to the work being done by Hapara with their Teacher Dashboard.
