A volume in Research Methods in Educational Technology Series Editor Walter F. Heinecke, University of Virginia While Research on the effectiveness of electronic portfolios for assessment and accreditation is emerging, many who are now using, or who are beginning to use, electronic portfolios are looking to justify the cost and effort involved. The purposes of this volume are to create an in-depth portrait of ways in which electronic portfolios efforts can be evaluated effectively, and to provide examples of e-folio evaluation in the form of case studies. The intention of these chapters is to serve as models for assessment and evaluation of electronic portfolios in teacher education, as well as to spark further investigations on this tool that is becoming ubiquitous in so many SCDE's across the United States and abroad.
