The Joan Ganz Cooney Center has conducted a national survey of more than 1500 parents of children ages 2-10 to find out how much of children's media time is devoted to educational content, platform by platform, age by age. "Learning at Home: Families' Educational Media Use in America" is the first comprehensive analysis of parents' experiences with the educational media their children use: Which subjects do parents feel their children are learning the most about from media? Which platforms do they perceive as being most effective? And what are some of the obstacles to greater use of educational media? All of these issues are explored by age, gender, race/ethnicity, and socioeconomic status. The report measures the degree to which children and parents use media together, overall and by platform, and looks at how this joint media engagement changes as children get older. The study also examines children's reading behaviors, especially online or on electronic reading devices. The full text of the questionnaire and all topline results are appended.
