This ERIC Digest examines the uses of databases in the social studies, including what a database is and how to use it, types of databases available for social studies classroom use, and the role this educational tool can play in achieving the goals and objectives of the social studies. A distinction between print and computerized database files and a simplified example of the use of Boolean logic in searching computer databases is provided. Two types of databases currently applicable in the social studies classroom, on-line databases and database software, are then examined. Listed are some of the on-line databases relevant as student research tools in the social studies, including The New York Times Information Service; America: History and Life; Historical Abstracts; Facts on File; Educational Resources Information Center (ERIC); and Magazine Index. Uses of database software are discussed and examples of commercially available database software programs are also provided. That database development and maintenance are fast becoming essential skills for effective citizenship participation is offered as a compelling rationale for incorporating this tool into social studies instruction. By creating and using databases, students develop research and organization skills. By searching databases, they learn to identify information needs, make problem statements, retrieve and sort information, and design strategies for organizing data. (LH)
