This resource represents a virtual library of still and moving images, documents, maps, sound clips and text which make up United States history from the Pre Columbian era to the early 1990s. The interdisciplinary range of materials included is compatible with standard textbooks in middle and high school social science, social studies, history, and art history courses and is designed for interactive use by teachers and/or students. The videodisc provides access to 2,512 still images, with captions and overviews, for research, independent study, or a wide range of instructional purposes. Images include illustrations, paintings, and photographs of historical figures and events, political cartoons, historic sites, architecture, artifacts and works of art. Sixty eight motion picture clips present persons and events from Theodore Roosevelt and the Rough Riders to President Clinton and Newt Gingrich. Sound bites pair brief recordings by individuals who made history or were witnesses to historic events with appropriate visual images and printed captions. The materials are arranged in 10 sections according to time period. Each section contains an overview, narrated by Charles Kuralt, which may be used as an introduction or a review of the period presented. Basic, intermediate, and advanced level student quizzes are provided on the CD-ROM. The interactive function allows the user to import additional digitalized pictures and create specialized presentations. The barcoded, annotated videodisc Master Guide, and the CD-ROM Index locate specific items and allow data grouping by keyword category. (MM)
