The articles, in this issue, by more than 40 authors, are divided into five parts: the first two parts provide an historical perspective of radio and television (both commercial and educational) and a basis for judging the impact of broadcasting on society; the third part concerns the teaching of broadcasting in the school and the uses of radio and television for supplemental, enrichment, or direct instruction within the curriculum; the fourth part surveys future utilization of these media in the schools--e.g., television for the exceptional child, teacher and administrator roles, closed circuit television; and the fifth part contains advice and direction regarding the study and uses of radio and television in the school. A bibliography on radio and television is included. (JMC)
