These instructions describe the use of BRIDGE, a computer software simulation model that is designed to compare the costs of expanding a college campus using distributed instruction (television or asynchronous network courses) versus the costs of expanding using lecture/lab type instruction. The model compares the projected operating and capital costs of the two types of campuses over a period of years, with cost projections based on the values of approximately 100 parameters that describe the general context of the simulation, and the resource requirements and associated costs of the lecture/lab and mediated campuses. The instructions provide a step-by-step guide to using the BRIDGE software, including the adjustment of default settings. Five appendixes provide information on the implications of various combinations of remote sites and campus course-sharing options, average section enrollment versus average annual enrollment, faculty salary calculations, distribution of faculty effort, and BRIDGE the web site.
