The objectives of this volume are to demonstrate methods for the use of computers in undergraduate instruction of geography; and to develop geographical course material so that, as time-shared terminals become more widely available, geographers will have course material whose learning achievement has been demonstrated. The editors provide a brief introduction to computer assisted instruction. They describe five computer based programs, covering the concepts of map projections and scale, climate types, energy budgets, urban geography, and spatial association. The learning objectives, computer language, and equipment used in each program are noted. In addition to the actual program, they provide flow charts, sample printouts, chargs and graphs. Two generative computer programs are described which are not dependent upon time-shared terminals. Students enter variable information, into a model of a process and note the change in the model. One model can be used to illustrate how the land use pattern is altered by environmental change. The other model uses an inexpensive analyzer, an analog field plotter, to serve as a link between a set of assumptions and the cartographic portrayal of the consequences. Some chapters are supplemented by bibliographies. (JY)
