Presented is the final report of a 3-year project in which an instructional program model was developed and implemented with 103 educable mentally retarded and learning disabled children (6-to 10-years old) in three Mississippi schools. General objectives of the project are said to include development of an experimental special education model which could be adopted by a school system and of a model curriculum involving individual and small group instruction. Noted are concepts on which the Instructional Program Model is based such as regular class placement (in non-graded classes), small group and individualized instruction, and instructional strategies derived following comprehensive diagnosis. Outlined in detail are the following curriculum units: math (Cuisenaire Rods), social studies ('Our Working World'), sciences, reading, language, and perceptual-motor skills. Examination of the project model includes job descriptions of the staff. Summarized are services and evaluation given by the medical, speech and hearing and psychological consultants, and by the social worker, and principals. Test data are analyzed to reveal the children's progress in reading, perceptual motor development, and intellectual and psycholinguistic abilities. A major finding reported was that 101 of 103 children involved in the program obtained achievement gains that would allow them to read independently as well as under instruction. (LS)
