This guide demonstrates the many ways in which social studies departments can use microcomputers to teach U.S. history. Computers can be used to enhance the learning process by assisting students in recording and categorizing data, formulating conclusions, and establishing concepts. This guide is intended as a supplement to existing curriculum materials, presenting possible alternative methods for teaching individual topics. Lesson plans for 104 topics are presented and include the topics of U.S. history from early European contact to the present time, technological developments, foreign policy, government and politics, the Constitution, and map skills. Appendices included are: (1) "The Constitution of the United States of America"; (2) "Amendments to the Constitution"; (3)"Software Used in This Text"; (4) "Software Duplication Guidelines"; (5) "Copying Public Domain Diskettes--MS DOS"; (6) "Copying Public Domain Diskettes--Apple II"; (7) "Caring for Your Diskettes"; and (8) "For More Help...."
