Interactive Classroom Television Systems: Educational Impact on Partially Sighted Students.

摘要

An Interactive Classroom Television System (ICTS) is a way of creating a visual classroom environment for partially sighted students by making use of the magnification brightness and contrast capabilities of television cameras and monitors. More precisely, an ICTS is a multicamera, multimonitor closed circuit TV system with videotaping and videoreplay capacity. Such a system permits teachers and their partially sighted students to be in continuous two way visual communication with one another. Moreover, it allows partially sighted students to function visually in classroom situations that are closely akin to those experienced by their fully sighted peers; that is, they can read ordinary printed matter, look at pictures, write with pen or pencil, do workbook problems, consult the blackboard, draw or paint. Thus the use of an ICTS both prepares students for eventual matriculation into classrooms for the fully sighted and provides an appropriate visual aid which enables students to make the fullest possible use of their residual vision. The first two years of an ICTS demonstration project suggest that it has a strong and stable positive impact on the learning experiences of partially sighted elementary school students.
