수행평가를 위한 교육공학적 접근: 웹 기반 전자포트폴리오 개발 = Technological Approach to Performance Assessment: Development of a Web-Based Electronic Portfolio

다국어 초록 (Multilingual Abstract)

This study empirically examined the effects of technology to support performance-based classroom learning and assessment by developing a web-based electronic portfolio prototype and applying it into an elementary school in Korea. Recently, the role of portfolios as a tool to support performance assessment is highly stressed for improving the quality of classroom learning and instruction. However, its practical usefulness is very limited mainly because it requires too much time and space for managing students` portfolios. Using a computer`s capabilities of rapid information processing, multimedia supporting, limitless information storing and random accessing to the information may overcome the practical problems of traditional paper-based portfolio assessment. Based on this idea, a web-based electronic portfolio system was devised, developed and implemented in an elementary school`s fifth grade classrooms. Data collected and analyzed through student`s portfolio and survey indicate that web-based electronic portfolios support efficient and effective performance assessment. It was also found that students were actively involved in performing authentic tasks, reflecting and thinking deeply while developing their electronic portfolios and evaluating others`. In conclusion, electronic portfolios have potentials to make learning, instruction, and evaluation of a classroom more performance-oriented and integrated.
