Every lesson asks memory to do three things: encode (take it in), store (keep it) and retrieve (bring it back out). Teaching usually focuses on the first. Learning depends on the third.

Try it: press Learn it, then Recall it a few times. Then let a week pass and recall again.

• Working memory is a small desk; long-term memory is a huge library.
• Every successful recall thickens the path back — and an effortful recall thickens it most.

In your class: plan moments where students pull ideas out, not only moments where you put them in.
