Practitioner Development

A classroom demonstration of self-monitoring, reactivity, and interobserver agreement.

Carr et al. (1995) · The Behavior analyst 1995
★ The Verdict

Run a 10-minute clicker demo to let students experience IOA error and reactivity before you assign real data collection.

✓ Read this if BCBAs who teach measurement classes or run staff training in schools.
✗ Skip if Practitioners looking for new treatment data or client programs.

01Research in Context

01

What this study did

Dugan et al. (1995) ran a 10-minute classroom demo for college students. Each student watched a short video and quietly pressed a clicker every time a target behavior happened.

After the clip, students compared counts with a neighbor. The teacher then explained why numbers often differ and how watching your own behavior can change it.

02

What they found

The paper does not report data. It simply describes the steps so other instructors can copy the activity.

03

How this fits with other research

Bailey et al. (2010) took the same self-monitoring idea and gave it to classroom aides. Aides used a one-page checklist to track their own token-economy steps. Integrity rose above 90% and kids’ readiness skills improved.

Romani et al. (2018) moved the IOA lesson to a psychiatric unit. Staff carried clickers, timers, and short sheets. IOA jumped for all eight children with ID/DD.

Bernardy et al. (2023) and Walker et al. (2021) are like the target: each offers a ready-made class activity with no new data. Together they show that demos stay popular when instructors want quick, low-prep lessons.

04

Why it matters

Use this 10-minute script the next time you teach IOA or reactivity. Students feel the measurement problems firsthand instead of just hearing about them. Once they grasp the concept, you can point to Bailey et al. (2010) and Romani et al. (2018) to show how the same tools fix real-world staff integrity and data quality issues.

03Original abstract

A brief classroom demonstration designed to introduce students to the concepts of self-monitoring, reactivity, and interobserver agreement is presented. The demonstration provides students with opportunities to monitor their own behavior, record the behavior of others, and calculate interobserver agreement percentages. Results of using the demonstration with students from two classes are presented.
