The geography unit is designed for use in upper elementary grades. The unit objective is to help the student learn facts about the landscapes of the United States, the Netherlands, Australia, Russia, and Central Africa, and acquire generic ideas which he can apply to the analysis and comparison of other landscapes. The unit is an attempt to apply David P. Ausubel's concept of advance organizers to an elementary social studies unit. During the first three days of the unit, a conceptual rural landscape model is taught as the advance organizer. The following inclusive organizing model concepts are identified and developed: population, density, culture, earth complex (land, climate, vegetation), and technology. Specific informational data within this general framework is then presented in each case study. Through questioning techniques the teacher leads the student through an analysis of the data. Among the 18 units outlined are the following: 1) the family farm in the United States; 2) the Netherlands; high population density and extensive sheep stations; 4) the earth complex of the U.S.S.R.; huge and cold; and 5) Ituri Pygmies: subsistence hunters and gatherers in Central Africa. An overview, a list of terms used, an outline of unit ideas, and course content including diagrams, pie charts, graphs, tables, maps, and questions are provided for each unit. (RM)
