The Development and Use of Literacy Portfolios for Students,Classes, and Teachers
Abstract:Portfolio assessment is one of the most interesting and widely discussed of the new alternative assessments. In this paper we explore the portfolio metaphor as it is applied to literacy portfolios. We suggest that portfolios provide a powerful tool for the enhancement of instruction and assessment, addressing educators' concerns about authentic assessment, documentation of academic progress, and teacher and student involvement. However, we caution that there are many important and unresolved issues that must be confronted if portfolio assessment is to succeed. Fundamental issues of validity and reliability must be addressed as well as practical issues of implementation, standard setting, sufficient resources, and teacher expertise. We argue that the ultimate success of portfolios will rest on our ability to communicate portfolio-based assessment information to others. We offer the teacher's class portfolio as a promising strategy for aggregating and reporting information, while preserving the integrity of individual student portfolios and teacher judgment. Whether the emphasis is on individual student portfolios or classroom portfolios, educators must be committed to the staff development and additional research that portfolio assessment demands.
