Home visitors were used to teach mothers to be more effective educational change agents in their own homes. The one-hour visits continued over 30 weeks. The initial sample consisted of 72 Negro mothers and their first grade children. All children has had 8-week summer Head Start. Five treatment groups were (1) Mother-Involved Cognitive home visitor actively solicited the mothers' participation, and content supplemented the first grade curriculum, (2) Child-Centered Cognitive home visitor worked only with the children and did not solicit mother involvement, content same as for first group, (3) Mother-Involved Physical Training home visitor actively solicited mothers' participation, content designed to teach gross motor activities, (4) Local Control, and (5) Distal Control. The children were pre- and posttested on measures of intelligence, readiness and achievement, and the Maternal Teaching Style Instrument was used to assess the mothers' teaching behavior. Results suggest that a good treatment program might be a cognitive program which works to involve the mother by first demonstrating improvements in the child's behavior. (NH)
