Blurb/Shorttext:
In this study, I reviewed the literature in ePortfolio systems and Web2.0 technologies, discussed design problems in practices, and then developed an Information Systems Design Theory (ISDT) for the next-generation ePortfolio systems guided by the design theories, practices, and a design research methodology by Walls et al. (1992). Following this ISDT, I developed KEEP Social Learning Suite (SLS) based on an open-source Carnegie-funded ePortfolio project. New social learning features implemented in KEEP SLS include: search, browse, annotation, blog connection, and group collaboration. I conducted usability tests and refined the system accordingly. Finally, I evaluated KEEP SLS by surveying volunteer subjects who had used KEEP SLS within the period of one month. The results show significant improvement in the users’ perceived value of the new system in terms of usefulness as a tool, effectiveness in achieving users’ goals, knowledge, learning, and social effects. The results also reveal that the perceived value of the system are positively related to SLS participation and perceived ease of use.
