Electronic portfolios or ePortfolios are digital collections of work that allow for multimedia content and reflection. They serve purposes like celebrating learning achievements, tracking personal growth, creating employment portfolios, and presenting work to audiences. ePortfolios offer advantages over traditional paper portfolios like requiring minimal storage space, allowing easy backups, being portable, and increasing technology skills while remaining learner-centered. Web 2.0 tools are well-suited for ePortfolios as they are mostly free, accessible online from anywhere, encourage interactivity and engagement, and can incorporate multimedia content like blogging and digital storytelling beyond just text.
