ABSTRACT

Sciences at Stanford University has operated a three-year computer-assisted instruction (CAI) network for hearing-impaired or deaf students; the effectiveness of the two main curricula in the program, elementary mathematics and language arts, was evaluated. The computer network spans the United States and in it three years has Involved 5,000 deaf students. The curriculom in elementary mathematics is divided into strands, serie. t related problems, and the language arts program tries to teach gr,., atical rules by the inductive approach. Groups of students were systematically selected for evaluation of the two curricula and received pre- and post-tests. The results showed that CAI could be used successfully by deaf students and that gains in mathematical computation two tio three times greater than classroom instruction could be achieved by CAI. Furthormore, these gains could be precisely predicted from the number of CAI sessions. (NH
