Isolated facts may be learned and remembered for no apparent reasons
a student may learn and remember that Charles G. Dawes served as vice president in the administration of Calvin Coolidge and at the same time learn the names of other vice presidents
Most frequently, though, a specific learned fact is related to others in a total set or to a larger body of information
a student may learn a number of facts about Mexico that are related to each other in the sense that they pertain to aspects of Mexico's geography, economy, or culture
