The Computer Pilot Program of the Division of Computer Information Services of the New York City Board of Education was designed to investigate the claim that comprehensive computer-based instruction (CBI) might best be used to improve the basic skills of educationally disadvantaged students. This ongoing project is designed to identify comprehensive CBI programs and implementation factors that can combine to positively affect the academic performance, attendance, and attitudes of educationally disadvantaged students. In the 1987-88 school year, 13 such programs were placed in 26 elementary and secondary schools in New York City. The investigation consisted of site observations, interviews with staff members and students involved with the programs, statistical comparisons of students' 1989 and 1988 scores on city-wide tests of reading and mathematics achievement, and questionnaires sent to the vendors of the CBI programs. The programs were generally well received by both staff and students, and their use generally resulted in significant achievement gains; however, students in the lower grades tended to show greater gains than students in the higher grades. Almost all of the programs involved both computer management and computer delivery of instruction. All but two programs covered reading, language arts, and mathematics, and many covered other subjects as well. Most of the programs used a task-analytic, learning-by-objectives approach, and about half of them were designed specifically for remedial populations. Most ran on either IBM, Apple II, or proprietary networks. This report summarizes these findings for each of the 13 programs evaluated. (BBM)
