A computer-assisted instructional system has been implemented in 21 elementary schools in Chicago. The system runs on a UNIVAC 418-III computer which processes concurrently the reading, language arts, and mathematics drill and practice strand programs of the Computer Curriculum Corporation. All students participating qualified under the Elementary and Secondary Education Act Title I guidelines for compensatory education and all were achieving at least one year below grade level upon entering the program. Results of the project after the first year showed it to have been highly successful. Individualized instruction was provided, and teachers were freed from drill activities for more creative work. Most importantly, students showed gains to nearly one month for each month in the program, a figure substantially better than the national average for compensatory education students, which stood at 5.6 months for every 8 months of instruction. As a consequence, further expansion of the program to 11 new schools was planned for the following year. (PB)
