The purpose of this study was to investigate the categorization capacity of College students in a categorizing grid of general chemistry compounds and to compare their classification ability with other categorization schemes like conceptual maps and tables.  These studies have been done for several semesters with about 50-60 subjects for reproducibility.  Almost all students have showed very little knowledge of the classes of compounds/taxonomic rules.  There was not significant statistical difference between the mean scores of majors/non-majors.  Since classification is pervasive in nature and science this study is relevant in Science Education.
