Language Development Support Systems (Project LDSS) offered 215 limited English proficient (LEP) students at two New York City elementary schools the opportunity to improve their English skills through special language learning centers. These language learning centers were established at both schools and provided students with instruction in reading, writing, and content area subjects. Students were also trained in the use of microcomputers. Computers were used to assist in the instruction of certain subjects. The project's primary goals were to increase language development and reduce language regression in students while teaching them to become computer literate. Technical assistance and opportunities for development were made available to staff working with these students. A secondary objective of the project was to increase staff effectiveness at fulfilling job-related responsibilities. A statistically significant improvement in students' scores on the Degrees of Reading Power test indicated that the project achieved its primary objective, and observations of educators' classroom performances suggested that the secondary objective was also realized.
