A comparison of three methods for eliminating disruptive lunchroom behavior.

The researchers tested three ways to stop loud, out-of-seat lunchroom behavior in fourth and fifth graders. They used an alternating-treatments design. Each day kids got either basic rules, basic rules plus punishment essays, or basic rules plus short 'mediation' essays they wrote themselves.

The mediation essay asked kids to name what they did wrong and how it hurt others. Kids wrote it right after lunch if they broke a rule. The study ran during normal school lunch periods.

Adding the student-written mediation essay almost wiped out disruption. Basic rules alone helped a little. Punishment essays helped a bit more. Mediation essays beat both by a wide margin.

The effect showed up fast and stayed strong across the whole study.

Fiene et al. (2015) looked at 18 single-case studies on behavior contracts and found a solid, mid-size benefit. Their meta-analysis covers contracts that reward or fine tokens, similar to the basic rules used here. The 1974 mediation essay gives an even bigger drop in problems, suggesting the reflective writing piece adds extra power.

Tracey et al. (1974) ran in the same year and also used fourth graders. They compared reward tokens versus cost tokens. Both token styles worked equally well. The mediation essay outperformed their best token result, showing a free, low-prep writing task can beat buying and managing tokens.

McKenna et al. (2017) moved the same lunchroom-disruption goal into today's classrooms but used function-based replacement training for individual kids. Their approach cut problem behavior too. You now have two solid choices: teach a new replacement skill one-on-one, or add a quick group mediation essay after lunch.

You can copy this tomorrow. Post three lunch rules. If a student breaks one, hand them a half-sheet that asks: 'What rule did I break? Who did it hurt? What will I do next time?' Collect it on the way out. No tokens, no money, no extra staff. The 1974 data say you should see a fast, big drop in noise and wandering. Try it for two weeks and track rule violations. If it works, you just saved your recess duty voice.
