Using performance feedback to improve treatment integrity of classwide behavior plans: an investigation of observer reactivity.

The researchers wanted to know if performance feedback helps teachers stick to class-wide behavior plans.

They watched several teachers and gave them quick feedback notes. Then they checked if the teachers still followed the plan when no one was watching.

A multiple-baseline design showed each teacher got feedback at a different time.

Every teacher’s plan use went up right after feedback.

Scores stayed high even when the observer left the room.

Observer reactivity did not matter — feedback worked either way.

Ingham et al. (1992) did the same thing earlier in special-ed rooms and saw the same lift. Their study is a clear predecessor — same method, different kids.

Zhu et al. (2020) pushed the idea further. They gave feedback over Zoom to BCBA trainees in China and still raised fidelity. This shows the trick travels across ages, cultures, and screens.

Downs et al. (2008) ran almost the same design in the same year. Instead of class plans, they targeted discrete-trial accuracy. Both papers landed on the same takeaway: brief feedback after training keeps skills above 90 %.

You can stop worrying that your presence skews results. Give teachers (or aides, or parents) short, specific feedback right after you watch them, then walk away. The skill sticks without you. Use email, Zoom, or a sticky note — the medium is less important than the quick, clear praise and correction. Try it in your next classroom visit: five minutes of feedback, then step out and see the plan hold.
