This guide provides an introduction to many different types and sources of social studies materials. The guide is divided into three sections representing classroom material, outreach activities, and professional resources. Each section is subdivided by resource type. Larger sections use categories to facilitate location of material by curriculum field; the typical arrangement of categories is General, Anthropology/Cultures, Civics, Economics, Geography, and History. Smaller sections are alphabetically arranged by the title of the resource, organization, or program. The first section covers "Classroom Instructional Resources," such as textbooks, trade books, multimedia resources, curriculum guides, journals, Web sites, dramatizations and model programs, games and simulations, and human resources. The second section covers "Outreach Activities," which typically involve experiences with learning sites or programs which are located or originate outside the school building. The third section covers "Professional Development and Planning Resources" for teachers. The index provides integrated access by subject and organization to all 845 entries. (BT)
