The use of audio/visual media as an aid to instruction is a common practice in today's classroom. Most teachers, however, have little or no formal training in this field and rarely a knowledgeable coordinator to help them. "The Practical Audio-Visual Handbook for Teachers" discusses the types and mechanics of many of these media forms and proposes ways in which they may be used for greater effectiveness. The suggested projects are designed for all grade levels and most scholastic subjects. The manual covers the uses of slides and filmstrips, motion pictures, overhead projectors, recorders and records; radio, T.V., and sound systems. Information is also given on chalk and display boards, flat graphics, mounting and lettering and three dimensional models. Photographs, graphs, charts, drawings and disgrams illustrate the handbook.
