Production and elimination of disruptive classroom behavior by systematically varying teacher's behavior.

The authors watched a fourth-grade class during math.

They counted every time a child yelled, left a seat, or poked a peer.

Then they told the teacher to change what she said.

In one phase she praised kids who were working.

In another phase she scolded the loud ones.

The phases flipped back and forth four times.

When the teacher tripled praise, disruption dropped fast.

When she tripled reprimands, noise and out-of-seat behavior rose.

The same pattern returned every time the condition switched.

Whitehead et al. (1975) extended this idea.

They showed that a quick verbal cue—"Look how Johnny is sitting"—lets the whole class copy the praised child.

Without the cue, only the praised kid improves.

Dunlap et al. (1991) seems to disagree.

They found that severe problem behavior makes adults teach less.

The two studies do not clash; they show a loop.

Teacher attention changes child behavior, and child behavior changes teacher attention.

Crane et al. (2009) add that untrained teachers often escape disruption by giving in.

This escape can accidentally reward the problem, so coaching staff is key.

You can cut disruption faster with praise than with corrections.

Set a timer if needed—three praises for every reprimand.

Also watch your own escape patterns; if you back off when kids yell, you may feed the fire.

Train aides to do the same and the loop works for you, not against you.
