Instructing beginning teachers in reinforcement procedures which improve classroom control.

Three new teachers tried a classroom game. When kids stayed on task, the teacher gave praise and let them keep playing.

If the class got rowdy, the teacher stopped the game and cut break time short. The researchers flipped these rules on and off four times to see what happened.

Each time the rules were in place, kids studied more and acted out less. When the rules stopped, the problems came back. The changes were big and fast.

Sanders et al. (1971) later used the same idea with third-graders. They swapped the game for a play area: finish work, go play. Both studies show that letting the teacher control free time keeps kids working.

Laposa et al. (2017) moved the trick into a juvenile lock-up. Teens managed their own DRL plan and still hit near-zero swearing. It shows the same logic works even when students, not teachers, hold the leash.

TCruz-Montecinos et al. (2024) ran a pure DRL group plan with autistic boys. They used the same ABAB flip design and also cut noise. The method travels across diagnoses and decades.

You do not need fancy tools. Praise, a game, and shorter breaks can flip a classroom in one period. Try pairing these three levers the next time you coach a new teacher or design a class-wide plan.
