In the process of learning, large numbers of schemas are created, thereby lowering the cognitive load of the information; for example, remembering how to do simple mathematical operations improves one's ability to solve complex algebraic equations. 

Schemas and Intrinsic Cognitive Load

The cognitive load caused by the complexity of the knowledge. Information with low element interactivity creates low intrinsic cognitive load.

There are three types of cognitive load: intrinsic cognitive load, extraneous cognitive load, and germane cognitive load.

Cognitive Load Theory

Intrinsic Cognitive Load

The cognitive load caused by the way in which the information is presented. Some procedures of instruction present too many elements at once, resulting in a heavy extraneous cognitive load that interferes with learning.

Extraneous Cognitive Load

The cognitive load resulting from the creation of schemas.
