The purpose of this module is to introduce students (grades 7-8) to the concept of change and factors influencing change. The module is composed of two major sections. Section 1 examines the development of the telephone system in the United States and introduces four futures forecasting techniques (Delphi probe, cross-impact matrix, trend analysis, and scenario development). In section 2, students use the forecasting techniques they have learned to examine the development and applications of the computer. In addition to futures forecasting techniques, readings, role-playing simulations, and small/large group discussions are employed. The module may be used as a separate unit of study, as a mini-course, or incorporated into social studies, history, general science, or language arts courses. (JN)
