Decreasing classroom misbehavior through the use of DRL schedules of reinforcement.

Three teachers tried a simple deal with their classes. If the kids kept talk-outs under a set number, they earned free time.

One class had teens with intellectual disability. Another had typical fourth-graders. The third was a small math group.

The plan is called DRL: reward low rates. The teachers counted talk-outs each period and posted the running total on the board.

Disruptive talking dropped fast in every room. Rates fell at least a large share within the first week.

Free time cost only five minutes per period, so kids still got most of their work done.

The teachers liked it because they could teach instead of scolding.

Conyers et al. (2004) tested DRO in preschool. DRO stops all disruption for a short time, then gives a reward. DRL lets some talking happen, just less. Both cut problem behavior, so pick the rule that matches your class goals.

Steinhauser et al. (2021) swapped DRL for DRA plus redirection to curb stereotypy. Their package worked when DRA alone failed. The pattern shows the whole differential-reinforcement family can be tuned to the behavior you target.

Demello et al. (1992) added a functional analysis before picking DRA. Their adult subject learned self-care while problem behavior dropped. The lesson: check why the student acts out, then choose DRL, DRO, or DRA.

You can run DRL tomorrow with just a tally sheet and a kitchen timer. Set a fair limit, post the count, and hand out short free time when the class stays under. It works in both special-ed and regular rooms, and it keeps the lesson moving.
