The Teaching Research Infant and Child Center classrooms service moderately to profoundly handicapped preschool children by providing comprehensive individualized curriculums emphasizing self help, motor development, language, and cognitive skills. Each model classroom contains 12 children with a teacher and an aide, and utilizes volunteers and parents to assist in instruction. Individualized instruction, one to one teaching relationships, is used. Evaluation data demonstrates that the educational procedures employed within the Teaching Research model produce an accelerated effect on learning rates that cannot be attributed to change or maturation. Data also demonstrates that the Teaching Research procedures and methodologies are sufficiently defined to be transmitted to another professional who can in turn produce similar effects in a different educational site. A chart presents random samples of individual programs. (SBH)
