Cognitive Load Theory

An instructional theory about working-memory demands for unfamiliar interacting information, prior knowledge, and learning. Intrinsic load can be managed through sequencing and prerequisites; avoidable demands should be reduced.

Cognitive load theory connects instructional design to limited working memory for unfamiliar interacting information and the organizing role of knowledge in long-term memory. Intrinsic load depends on both element interactivity and what the learner already knows; sequencing and prerequisite instruction can manage it. Extraneous demands arise from avoidable features of the task or presentation.

The familiar three-load account has evolved: some contemporary formulations treat germane processing as resources devoted to learning rather than a separate additive load. The practical aim is not to maximize mental effort. Provide enough structure for the learner to understand relationships, then reduce support as expertise makes earlier guidance redundant.

When to use it

When learners lose track of interacting elements or an instructional design imposes avoidable search and coordination demands.

How it can help

Match guidance and task complexity to prior knowledge, remove unnecessary processing, and fade support when independent performance warrants it.
