Notes are presented on classroom organization, discipline, motivation, and teacher concern for use with instructional radio. Attributes of a regular classroom and a good radio classroom are compared, including teacher/radio positioning, materials organization and presentation, the use of sound and silence, cueing and voice use, demonstrations, lesson plans and format, timing, student-teacher relationship, and individualization and pacing. Hints for making the radio program more like the classroom are also provided, and include having an opening theme song, greeting the students, using an opening involvement exercise, theme music to open each lesson segment, sound effects, announcing upcoming segments, providing clear demonstrations, using a single teacher and different format for each segment, making instruction clear and simple, consistent sequencing, keeping worksheets out of the way when not in use, keeping the pacing up throughout the program, establishing a quiet working atmosphere, using lesson summaries and relaxation segments, developing skills, and ending each day's work in a standard way.
