The booklet is designed to acquaint geography teachers with a variety of projected media materials and with effective techniques for their use in the classroom. Projected media include slides, filmstrips, opaque and overhead projections, and motion pictures. The use of projected media helps teachers simplify, clarify, analyze, and synthesize relationships between man and his environments. Using media in the classroom helps students form clear mental pictures of geographical principles, patterns, and concepts. One major advantage in using projected media is that teachers can prepare materials in advance that are specifically suited to the presentation of a particular topic. For media to be used successfully, teachers must adequately plan and relate the medium to the chosen topic. This booklet is divided into sections on various media, each containing discussion of the nature of the medium, advantages, disadvantages, special considerations, and selected references. Slides are flexible, available, inexpensive, easy to use, and combinable with other projected media. Filmstrips require a minimum of commentary, present a sequential development of an idea, are inexpensive, and contain informational captions. Overhead projectors allow the teacher to maintain eye contact with students, project many objects, and control the pace of the presentation; however, they are costly, require special storage facilities, and create distortion of images. Although motion pictures add realism to learning, offer technical flexibility, and are easily available; they are complex and expensive. The use of projected media involves principles of selection, introduction, facilities, presentation, and follow-up. (ND)
