In order to test the strengths of radio as a learning tool for children, research was conducted in which radio and television were compared in relation to their abilities to stimulate children's imaginations and to transmit information to children. The research involved a series of studies in which children were presented with two unfamiliar stories in both a radio and a television format. Each study involved 24 boys and 24 girls, in 2 age groups: 6 1/2 to 8 and 9 to 10 1/2 years. Studies included children from middle- and working-class white and black families. For the study of imagination, both the video and audio presentations were stopped prior to the ends of the stories and children were asked to complete them. As hypothesized, radio stimulated imagination more than did television, but this finding was most pronounced among white children. For the study of memory, children were asked to recount the story and were asked specific questions about its content. On most measures, memory was equivalent for radio and television. A reference list accompanies the text. Appendices to the report include the texts of the stories used in the studies, the scoring manual used in the studies of imagination, and the lists of questions used to measure recall. (Author/JL)
