The use of geographic information systems (GIS) in the classroom provides a robust and effective method of teaching the primary spatial skills of identification, description, and explanation of spatial pattern. A major handicap for the development of GIS-based learning experiences, especially for non-GIS specialist educators, is the availability of spatial datasets that are not only inexpensive and easy-to-use, but incorporate a large array of topical and regional themes. ArcAtlas Our Earth is a possible solution to these dual problems. This article describes the composition and structure of this database that is designed for academic and educational applications. It also provides a workable example, links the exercise to Bloom's Taxonomy, and the National Geography Standards, includes a suggested grading rubric, and provides suggestions for additional exercises.
