Stimulus control in the classroom as a function of the behavior reinforced.

Barnard et al. (1977) compared two ways to run a classroom token system. One group earned tokens only for correct academic work. The other group earned tokens for staying on-task. The teacher used an alternating-treatments design, switching the rule every few days. Kids were in late-elementary general-education classrooms.

When tokens paid for correct answers, kids kept working even after the teacher left the room. Disruptive behavior dropped and work output stayed high. When tokens paid for sitting quietly, work fell apart the moment the teacher stepped out. Academic contingencies won.

Wilson et al. (1975) got the same lift two years earlier. They used academic tokens with hyperactive boys and saw math and reading scores jump from 12 % to 85 % while hyperactivity fell to drug-like lows. Barnard et al. (1977) sharpen the point: the payoff is the product, not the posture.

Cariveau et al. (2017) extend the idea to group contingencies. They showed that a randomized class-wide system can keep second-graders engaged during small-group reading after the reward is gone. The thread is clear—tie rewards to academic output and the behavior sticks.

Mace et al. (1990) used the same alternating-treatments token design in a special-ed room. They found kids shifted their time toward the task that paid more tokens. Barnard et al. (1977) mirror that result: when correct work paid, kids gave more correct work; when sitting still paid, they sat still but learned less.

Stop reinforcing quiet hands and start reinforcing right answers. Put tokens, points, or praise on accurate math problems, completed readings, or correct science facts. Check the work, deliver the reward, then step back. The data say your students will stay productive even when you leave to grab copies, take a call, or support another kid. Product over posture—every time.
