Mastery learning moves tests of what it taught (~0.25) and barely moves independent measures (~0.05) — and time-to-mastery gaps widen, converting ability differences into time.

Teaching movement teaches movement: the skills improve, but transfer to cognition, achievement, or lifelong activity is near zero in the best trials.

Does teaching movement transfer to cognition, achievement, or lifelong activity? · physical-development · ages 4–18
Selective CTE high schools raise male graduation 8-10pp and early-career earnings 17-35% on lottery and cutoff designs; test scores, degrees, and every outcome for girls are flat.

Yes — sight-reading, performance and aural skill move about half a standard deviation under instruction — but the evidence is quasi-experimental and thinner than the transfer literature built on top of it.

Life-skills courses reliably teach the content and rarely change the conduct; behaviour moves only where instruction sits close in time to the decision, and driver education is worse than nothing.

Do life-skills courses — money, cooking, driving, health — change what students actually do? · practical · ages 6–18
Not at school: the largest randomised trials find nothing on reading, maths or cognition. A small effect on laboratory executive-function tasks is contested, may be real at ~0.2 SD, and is end-of-treatment only.
