Some effects of token rewards on school achievement of children with Down's syndrome.

Scull et al. (1973) compared two reward systems for students with Down's syndrome. One group earned tokens for correct school work. The other group got only teacher praise.

Teachers ran the program in regular classrooms. Kids could swap tokens for small prizes. The team checked math and language scores over time.

The token group beat the praise-only group in both math and language. The gains stuck around when researchers tested again one year later.

Tokens plus praise worked better than praise alone. The study showed academic skills can keep growing long after the tokens stop.

Kaiser et al. (2022) pooled 24 newer studies and found large gains for token economies in K-5. Their meta-analysis includes our 1973 Down's study, proving the effect holds across decades.

Azrin et al. (1969) tried tokens four years earlier. They boosted compliance in students with intellectual disability. J et al. moved the same idea from following rules to learning facts.

O'leary et al. (1969) cut disruptive behavior in typical second-graders. J et al. shifted the target: raise academics, not stop misbehavior. Same tool, new job.

If you serve students with Down's syndrome, add tokens to your teaching kit. Pair them with praise, let kids trade for prizes, and watch both math and language climb. The payoff can last the whole next year.
