The author discusses uses and sources of photographs as effective teaching aids in social studies classrooms. Pictures are not new among learning resources, but they adapt well to new focuses in social studies education. One third of the pamphlet explains how photographs can enhance learning. They can promote discovery learning, concept development, and affective as well as cognitive learning. They are useful resources for independent and ethnic studies projects. Situations are described in which photographs clarify values, reinforce learning, correct stereotypes, promote good self-images in children, and stimulate quiet students. Free sources of photographs include old textbooks, travel bureaus, family pictures from trips, embassies, and local and state libraries. Magazines, books, and study prints can be purchased specifically for pictorial study. Over 30 such resources are identified by title and publisher. Teachers are encouraged to mount pictures so they will last, keep files easily accessible, and cross-reference files to get greater use from the contents. Provocative questions for indepth study of pictures are suggested. The pamphlet concludes with a list of manufacturers of inexpensive cameras and film, and a bibliography of 15 books on the use of pictures. (AV)
