Why do we learn something better by doing it than by only watching or listening?

Answer: Doing makes you recall and apply knowledge, and mistakes show up at once

Hands-on practice suits the learning style most people are born with — Matching teaching to a personal learning style has not held up in research: reviews find no adequate evidence that people learn more when taught in their preferred style. Studies instead tend to find that the same method works best for all kinds of students, and active practice is one of those methods.

Doing makes you recall and apply knowledge, and mistakes show up at once ✓ — Doing forces you to pull knowledge out of memory and use it, and retrieving a memory strengthens it more than rereading does: in a classic experiment, students who practiced recalling a text remembered substantially more of it a week later than students who restudied it. Doing also exposes mistakes while there is still time to fix them. Across 225 studies, students in lecture-only science classes were 1.5 times more likely to fail than those taught with active learning.

Muscles store the new skill themselves, easing the load on the brain — Muscles do not store skills; so-called muscle memory lives in the brain, in circuits linking the cerebellum, the motor cortex and the basal ganglia. Practice reshapes those circuits until the movement runs smoothly, so learning by doing gives the brain more work, not less.
