A note on a simple procedure for redistributing a teacher's student contacts.

The researchers worked with a third-grade class. They told kids, "Finish your work, then go to the play corner."

They watched who finished work and who the teacher talked to. They wanted to see if the rule moved teacher time to slower workers.

More kids finished their work when the play corner waited. The teacher also spent more time with the kids who needed help.

The rule acted like a magnet. Finished kids left, so the teacher could focus on the rest.

Hall et al. (1968) used group prizes and games to raise study behavior. Both studies show simple teacher-run rules can flip a whole classroom.

Iwata et al. (1990) and Moxley (1989) worked with preschoolers and proved that if you reinforce a behavior, it shows up. The 1971 study moves the same idea into a real school lesson.

Thiessen et al. (2009) trained adults with a manual and a small bonus. Their work shows you can teach people to run tight contingencies like the play-area rule.

You can set up a quick completion rule instead of policing each desk. One cue—"Work done, then play"—boosts work and frees you to teach the strugglers. Try it next session: pick a fun corner, state the rule, and watch both work and attention shift.
