By illustrating words, symbols can help a student to learn and recall information. This is particularly true for those students who operate more visually and whose visual memory may help to recall facts. It is also true that symbols can help to remind students of a concept. The symbol itself cannot teach the concept, but once a concept has been understood, symbols can reinforce that understanding and help make the comprehension more permanent.

For example, we have developed many Science symbols where the images can help students to recall the meaning of the concept, even though they may be perfectly capable of reading the word. Even difficult concepts, such as voltage (the push sending the current round a circuit) and the current (the flow that results) can be well illustrated with symbols.
