Geography teachers have available to them a wide variety of audiovisual aids. But the methods by which these materials should be used to produce the greatest impact upon learning deserve careful consideration. The Audio-Visual-Tutorial (ATV) laboratory at Carroll College purposes to improve the content of the freshman-sophomore course in physical geography, stimulate interest, promote independent learning, provide flexibility of class meeting times, make adjustments for the diversity of educational backgrounds, and promote economy in instruction. Fifteen study carrels are equipped with tape transports, slide projectors, and space for displaying models, samples, and instruments as needed. A large demonstration table also exhibits materials and instruments. Eight millimeter continuous-loop, rear projection units, independent study booths, and a weather station are also provided. The course consists of laboratory work and discussion sessions. Approximately 40 per cent more content is thus presented and examination scores have improved 28.75 per cent. (MM)
