Spatial Concept Perspectives

We have gathered ~300 excerpts from published works about fundamental spatial concept terms. These have been cross-referenced with the concept lexicon appearing on the left. Those terms were drawn from the U.S.National Science Education Standards (NSES 1996) for topic areas B - Physical Science, C - Life Science, D - Earth and Space Science, as well as from the 1994 U.S. Geography Teaching Standards for grades 9-12. Those standards can be browsed here.

disciplinary perspectives on "adjacency"

adjacency

Adjacency can be thought of as the nominal, or binary, equivalent of distance. Two spatial entities are either adjacent or they are not, and we usually do not allow a middle ground (p. 36/see source for more).
