For: Teachers, instructional designers, course creators

Draft — awaiting approved content

Cognitive load theory splits the demand on working memory into three parts. Telling them apart is the single most useful skill the theory offers — it tells you what to cut and what to keep.

  • intrinsic
  • extraneous
  • germane

What it is

Draft section — approved definitions to be added for each of the three types: intrinsic (inherent difficulty), extraneous (presentation), germane (productive effort that builds understanding).

Why it matters

Draft section. Why the goal is to reduce extraneous load while protecting germane load — not simply to make everything "easier."

A practical example

Draft section. One example showing the same lesson re-designed to cut extraneous load.

A common mistake

Draft section.

How to apply it

Draft section. A short diagnostic for spotting each load type in your own material.
