In an effort to evaluate the effects of "Sesame Street", 943 3-, 4- and 5-year-olds, including disadvantaged children from the inner city, advantaged suburban children, children from rural areas, and disadvantaged Spanish-speaking children, were tested by adults from the children's own neighborhoods. Results indicate that: (1) the children who watched the most learned the most; (2) the skills that received the most time and attention on the program were, with some rare exceptions, the skills that were best learned; and (3) the program did not require adult supervision for the children to learn. The children viewing at home showed gains as great as, and sometimes greater than, children who watched at school supervised by the teacher. Various disadvantaged groups made as much progress as advantaged children in learning from television. Measuring techniques developed for the study proved especially valuable when combined with the services of coordinators and testers who lived in the communities being tested. (MK)
