This ERIC Digest promotes the use of museums as social studies teaching resources. Because of the wealth of information and the breadth of scope of material found in museums, they can be invaluable as resources for the classroom as well as for tours. The guide covers the recent trend of museums catering to the educator through the development of lesson plans, brochures, student classes, newsletters, videos, and even traveling outreach persons. The Digest identifies a wide variety of materials available both on- and off-site, including five specific web-sites. (KCM)
