The geographically informed person must understand that physical and human phenomena are distributed across Earth’s surface and see meaning in their arrangements across space. Geography usually starts with questions such as, “Where?” “What is it like here?” and “Why is this located there and not here?” When considering “where” questions, geographers seek regularities—that is, patterns as well as relationships among phenomena (the features of Earth and activities that take place on Earth). They describe and explain patterns in terms of distance, direction, density, and distribution. They use spatial concepts, processes, and models as powerful tools for explaining the world at all scales, local to global.
Therefore, Standard 3 contains these themes: Spatial Concepts, Spatial Patterns and Processes, and Spatial Models.
Spatial concepts provide a language for describing the arrangement of people, places, and environments. Arrangements can be characterized in terms of proximity, distance, scale, clustering, distribution, etc.
Once students start to identify spatial patterns and use maps and remotely sensed images to discover patterns, then they can begin to explore why the patterns and relationships among phenomena exist as they do, that is, what processes produce the patterns. Processes are the driving forces and underlying causes of observable patterns.
Students must understand the mechanisms underlying processes, from the physical activities that shape the environment to the human processes of economic development, urbanization, migration, and cultural change. Models are idealized and simplified representations based on assumptions about reality, and they can help students analyze spatial organization by demonstrating properties of physical and human features, by simplifying the complexity of reality, and by serving as a source of working hypotheses in research. Models can be organized along a continuum from concrete reality (a globe or a diorama) to higher degrees of abstraction and generalization (models of urban structures, spatial interactions, and physical processes).
Understanding these themes and related concepts enables students to explore the patterns of human and physical phenomena and the processes that influence these patterns. Students use models to convey knowledge and generalizations related to Earth’s spatial organization. The use of spatial thinking brings a deeper understanding and appreciation of the complexity and interconnectedness of the physical and human world.
