Results of the first 6 months of the Ypsilanti-Carnegie Infant Education Project are provided, including quantitative data and a case study, a discussion of the curriculum employed in the home and illustration of curriculum practices, and research design changes. The purpose of the project is to assess the effectiveness of systematic intervention by public school teachers, starting at the period of infancy, in preventing the intellectual deficits commonly found in children from disadvantaged populations. To control some of the important variables, four groups have been established: an experimental group, a contrast group, and two control groups. The experimental group utilizes home teaching by public school teachers; the contrast groups employs home visits by volunteer college students and young women from the community to provide adult attention for the child and service to the family; one control group is a no-treatment group receiving only the same testing as other groups; and the other control group is a no-treatment, no-testing group. Testing instruments used are: Maternal Behavior Inventory; Teacher's Report, Form B; Infant Cognitive Home Environment Scale; Infant Information Inventory; Infant and Maternal Medical History; Ypsilanti Picture Sorting Inventory; Bayley Infant Scales of Development; and Kagan Measures. The pilot study conducted during the first 6 months of the project focused upon organization of the home teaching program, the data collection procedures, and staff orientation. (DB)
