The effects of verbal instruction, modeling, rehearsal, and feedback on correct posture during flute playing.

Three elementary girls learned to hold a flute with correct posture.

The trainer used four steps: tell, show, practice, and give feedback.

They tracked posture during real band class and checked again one to two months later.

All girls hit almost 100 % correct posture by the end.

Good form lasted after lessons stopped.

The simple package worked without extra rewards or tokens.

Tarifa-Rodriguez et al. (2025) later moved the same four-step plan into a Facebook group for college students and still raised grades.

Hawley et al. (2004) warned that heavy drill does not always help skills stick, yet Ellen’s short rehearsal round did stick—showing quality feedback beats mere repetition.

Frame et al. (1984) also used a multiple-baseline design in elementary classrooms, but they needed public photo posters to cut dental plaque, while Ellen only needed instruction and feedback for posture.

You can copy the four-step package anywhere you need a motor skill: tell the rule, show the move, let the learner try, and give immediate feedback. No tokens, no tech, no long drills. Try it for handwriting grip, scooter safety, or tooth-brushing stance next Monday.
