The Albuquerque (New Mexico) Public Schools conducted a three-year study of integrated computer-based learning systems, including WICAT, Dolphin, PLATO, CCC, and DEGEM. Through cooperation with the Education Consolidation Improvement Act Chapter 1 program, four large integrated learning systems (ILS) were purchased and studied. They were installed and implemented in 1984. Due to budget constraints, the PLATO program was dropped from the study. The DEGEM system will be evaluated during the second year of the project and is not included here. The primary application of the ILS was to provide Chapter 1 students with supplemental instruction in reading, language arts, and mathematics through computer assisted instruction (CAI). The evaluation compared the four systems' effectiveness. Aspects of the evaluation included the match between ILS, curriculum content, and standardized achievement test content; instructional and technical characteristics; documentation; management systems; diagnostic placement; programming; staffing and training; cost effectiveness; and student and teacher perceptions of value. Results indicated the CAI programs were under-utilized during their first year, largely due to staffing patterns. Mathematics impact was generally greater than reading. The importance of a full-time laboratory operator was repeatedly noted. (GDC)
