The "Handbook of Research on ePortfolios" is the single source for comprehensive coverage of the major themes of ePortfolios, addressing all of the major issues, from concept to technology to implementation. It is the first reference publication to provide a complete investigation on a variety of ePortfolio uses through case studies and supporting technologies, and also explains the conceptual thinking behind current uses and potential uses not yet implemented. Over 100 international experts with countless years of experience lend this handbook the credibility that assures its readers of its extensive, recent, and reliable content. The "Handbook of Research on ePortfolios" is the first handbook to investigate commercial and academic ePortfolio systems--home-grown, off the shelf, and open source--and to supply proof-of-concept evidence of successful systems.
