This study developed a knowledge management behavior scale of e-portfolio for university students based on the approaches of Web-based fuzzy Delphi and fuzzy AHP. According to the experts' opinions, the constructs of the scale included knowledge sharing, innovation, acquisition, application, and accumulation. The items in each construct consisted of the activities of e-portfolio implementation, which were reflection, assignment improvement, self-evaluation, organization of learning contents, teacher feedback, review and learning, and communication and discussion. All the constructs and items had weights and ranks and were by acceptable reliability and validity. Among all the items, the overall weight of reflection was highest, while following was assignment improvement. It applied that reflection had a highest effect on knowledge management. Therefore, the scale can be used as a knowledge management performance measurement tool for e-portfolio implementation.
