Six dimensions of computer literacy for social studies educators to address are discussed. In preparing social studies teachers for the 21st century, educators need to determine which aspects of computer literacy are essential to incorporate into teacher education. First, teachers must have knowledge of the basic sources of information, such as relevant periodicals. Second, teachers must understand the process of communicating with microcomputers. While teachers do not have to be programmers, they must have some first-hand experience in trying to communicate with computers in order to appreciate their limitations. Third, teachers need to know about hardware components. Fourth, teachers must know about available software and its compatibility with hardware. The fifth area in which teachers must be knowledgeable is in microcomputer applications in the social studies. Programs can help students learn data processing and interpretation, communication skills, group participation skills, facts, concepts, and problem solving. Teachers can also use computers in the management of classroom tasks. And, finally, teachers must know about the social implications of microcomputers. (RM)
