This study of the use of television in full-day child care tested a variety of ways to use the Public Broadcasting Corporation's television program Mister Rogers' Neighborhood in child care programs. Part 1 presents the results of an initial survey of child care centers and home care providers in the Toledo, Ohio metropolitan area, while part 2 discusses a 5-month study of the use of Mister Rogers' Neighborhood and accompanying support materials at 27 day care centers. Observations of teachers and children, and written and verbal feedback by teachers, parents, and center directors, were assessed. It was found that Mister Rogers' Neighborhood helped child care teachers and providers enhance the emotional development of preschool children, and that parents had positive attitudes toward the use of "quality children's programming" in child care. Thirteen appendices include various teacher, parent, and director survey questionnaires, viewing schedules, planning and activity logs, and student observation forms. (MDM)
