Pillar IV: most learning is forgotten by design.
What it does
Pillar IV: most learning is forgotten by design. Build the engine — encoding, retrieval, spacing, interleaving, feedback — that makes it stick.
Before and after


How to use it
- Design each component of your retention engine. The designer reads your plans and flags the components left to chance — usually spacing and retrieval. Write how each component works in your course. Retention is engineered, not hoped for.
