The interactive classroom television system (ICTS) creates a visual classroom environment for partially sighted students using a multicamera, multimonitor closed circuit television system with videotaping and videoreplay capacity. This paper describes an evaluation of the educational impact of the ICTS on visually impaired elementary students. Chapter I describes the two ICTS sites and participants; Chapter II describes the evaluation design and data collection schedule, and presents the results of the first project year in three areas of evaluation: academic achievement, perceptual skills, and psychosocial mediators of school success. Chapter III describes changes introduced into the evaluation procedures, and examines outcomes for the second project year. The two years of evaluation data suggest that the ICTS has a strong and stable positive impact on students' learning experiences.
