"Preparing for Tomorrow's World" (PTW) is an interdisciplinary, future-oriented program incorporating information from the sciences/social sciences and addressing societal concerns which interface science/technology/society. "Beacon City," one of a series of program modules, is an urban land use simulation. Land use planning techniques patterned after the work of Ian McHarg and strategies/techniques developed in the emerging field of futuristics (such as futures forecasting) are integral parts of the module. Like other PTW modules, Beacon City promotes responsible citizenry with increased abilities in critical thinking, problem solving, social/ethical reasoning, and decision-making. Provided in this teaching guide is an overview of the module (which includes a description of the simulation, objectives, and discussion of strategies for promoting student development) and a discussion of the Socio-Scientific Reasoning Model (theoretical basis of the PTW program). Instructional strategies for module activities are also provided. These include suggestions for using the filmstrip/audio-cassette recording (complete script provided), a game, role playing cards, data files, and student worksheets. The module is recommended for such high school courses/areas as social studies, history, geography, urban studies, environmental planning, and earth science. (JN)
