Cognitive load theory

/ˈkɑɡnətɪv loʊd ˈθiəri/ noun

Definition

A theory that describes how the human cognitive system processes information, proposing that working memory has limited capacity and that learning is optimized when cognitive load is managed effectively. The theory distinguishes between intrinsic, extraneous, and germane cognitive load.

Etymology

Developed by John Sweller in the 1980s, combining 'cognitive' from Latin 'cognoscere' (to get to know) and 'load' referring to the amount of mental effort required. The theory emerged from research on problem-solving and instructional design.

Kelly Says

Your working memory is like a juggler who can only keep a few balls in the air at once - add too many and everything crashes down! This is why multitasking makes you less efficient and why good teachers break complex topics into digestible chunks.
