Practice means designed work with feedback — Ericsson’s construct, not Gladwell’s hour ticket.
Where Macnamara et al. 2014 published domain bands (games ~26%, music ~21%, sports ~18%, education ~4%), this page uses those rounded figures and does not invent new precision.

Checklist
- A learner changed — The only test.
- A second representation — Design.
- A check existed — Not hope.
- Charisma discounted — Halo.
- System named — Not only a star.
- No national teacher-gene — Editorial.
- Late path honoured — Low early window.
- Ethics of the room — No humiliation as “rigour”.
Drills
- Error clinic — Five wrong answers, find the bug.
- Silent demo — Materials only, Montessori-ish.

- Hint ladder of three — Zone.
- Two-minute teach-back — Gap.
Pitfalls
- Born-teacher talk — Stops design.
- Stage halo — Video.

- Ignoring the system — Finland’s lesson inverted.
Tools
- A second representation — Always packed.
- An exit ticket — Change score.
- A colleague’s eyes — Lesson study.
- Vygotsky in one page — Zone, not a poster.
Teaching talent: design the hour; retire the poster. Education is not a diagnosis.
