As discussed earlier, schema represents a generic concept and
is the make-up of how our knowledge is organized within memory. These schemas are then used to make sense
of new information. Schema is constantly
changing and evolving as new information is processed. Three methods have been identified by
Rumelhard and Norman (1978) to modify or create schema:
Accretion: an abstract
concept is added to an existing schema connecting to that schema without
altering its essence.
Tuning: an existing schema is modified slightly to better conform to existing experience.
Resturcturing: the creation of a new schema which substitutes or incorporates old schema.
