The document outlines the 18 standards for geographic education published in 1994 to guide instruction in the United States. The standards describe the key concepts and understanding of geography that students should master, including how to use maps and technology to analyze spatial patterns on Earth's surface; understand the relationship between physical systems and human systems; comprehend the characteristics of places, regions, and human and physical environments; appreciate the connections between environmental and societal changes; and apply geographic knowledge to interpret the past, present and future. The overall goal was for all American students to become geographically informed through implementation of the standards in classrooms.
