The ideas and theories of Immanuel Velikovsky are introduced to social studies teachers and a nine-week minicourse designed to investigate his theories is reported. The contradictions and inconsistencies that Velikovsky found between the events as recorded in original records of the ancient Middle East and the chronological timetable of this historical period as it is presently constructed, form the basis of this inquiry unit for high school students. Four general course objectives listed and discussed are: to familiarize students with the basic works and theories of Velikovsky; to examine some of his theories in light of historical, scientific, cultural, and religious evidence and cources; to review the chronology of ancient history as presently constructed and compare it with the revisions suggested by Velikovsky; and to review the reaction of scientific and literary critics to his published works and theories. Through use of both the expository and inquiry modes of learning, the unit emphasizes the students' efforts to identify and articulate the inconsistencies which present themselves, and to make decisions to reconcile these discrepancies. Learning activities and instructional materials are suggested; materials distributed in class are reproduced. (KSM)
