This videotape cassette portrays the role of portfolios for educational improvement through assessment in a California classroom participating in the Apple Classrooms of Tomorrow (ACOT) educational technology program. Elementary school students at the Stevens Creek School used computers for writing assignments, and included the best of their assignments in portfolios of completed work. The portfolios are computer-stored. Interviews with students and teachers indicated that both found it relatively easy to use portfolios for conferences and for discussions of the writing process, but that using portfolios for assessment has proven to be more complicated. As in all assessment, setting the standards is of primary importance. Teacher inservice workshops have been conducted so that teachers could learn how to use portfolios for fair and meaningful assessment. Coordination of school district goals and the technology program will eventually enable the establishment of benchmarks for the measurement of achievement at various levels of education. (SLD)
