Abstract: This survey paper uses a framework derived from Herman and Winters (1994) to analyze seven selected research studies for evidence of electronic portfolios’ technical quality, implementation effects, fairness, feasibility, and tool effects. Analysis sought to determine what methodologies and instruments for data collection yielded useful information about electronic portfolios, and what the findings and methods suggest about directions for future e-portfolio research. The author’s recommendations are placed in the context of an educational technology research agenda proposed by leaders in the field.
