Not to be mistaken for a
flash card, a learning card is basically a small paper card containing the name of a single
subject,
idea,
component or any other small part of a body of
knowledge such as an
academic field of
study. Apart from the name, the card holds a brief but precise description of the subject, component etc. By simply flipping through a small stack of cards, a person can grow familiar with enough pieces of a field of study to understand its basics.
Well-made learning cards have a simple
system of
reference between them. A common system is to simply have words in a cards description section written in
italic or
bold, if that word corresponds to the name of another card. This way, the cards form a collected whole, showing the
relations between things described.
