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.
