The Last Fifteen Minutes: A Grade 8 Class That Unravels
Mahmoud teaches English to 42 boys in Grade 8 at a double-shift school in Irbid. The class meets five times a week in 40-minute periods. The last 15 minutes of nearly every lesson collapse: two students at the back call out, neighbours turn to talk, and Mahmoud raises his voice until the bell. The school behaviour policy allows a written referral but forbids sending a student into the corridor. He has already moved the two students to the front, kept them after class twice, and telephoned one father, who said his son is 'bored because the lesson is easy'. Reading data show 11 students at grade level, 19 below, and 12 who are strong orally but write very little. Mahmoud's supervisor visits in three weeks and expects to see 'clear classroom routines and evidence of differentiation'. Mahmoud is exhausted and is considering requesting a transfer.
1. Analyse the disruption with an antecedent–behaviour–consequence frame. What does the pattern suggest about the likely function of the behaviour, and what should Mahmoud change first? Explain why repeating a seating change would be a poor use of the three weeks before the visit.

What the pattern shows. The behaviour is concentrated in one predictable window (the final 15 minutes), not spread across the lesson. That points to the task and its consequences rather than to fixed traits of two students.
- Antecedent: the class moves into the end-of-lesson segment, usually with a single instruction given while 42 students are still settling, and the task is the same for readers three years apart in level.
- Behaviour: call-outs that spread to neighbours.
- Consequence: teacher attention (a reprimand), peer laughter, and the segment quietly abandoned at the bell.
Two functions are plausible and testable: escape from a task that is too hard for the 19 below-level readers and too easy for the 12 strong oral students, plus peer attention.
First change. Restructure the final segment into a short, tightly timed, visibly differentiated task with a fixed end point - for example an 8-minute paired oral task with sentence frames for the below-level group and an open response for the strong oral group - collected as an exit ticket at the door. That removes the ambiguous downtime that feeds both escape and attention.
Why not seating again. Seating was already tried and did not hold, so it addresses the wrong variable and produces no evidence. Instead he needs a baseline: for three lessons, tally call-outs in 5-minute blocks and note which activity was running. That turns a morale problem into data he can show the supervisor.
2. Design a two-week routine plan that also addresses the wide reading spread and would be visible to a visiting supervisor. Specify timings and what evidence of implementation will exist.

Lesson frame (40 minutes, used every period).
| Minutes | Segment |
|---|---|
| 0–4 | Entry task on the board, started before the bell; teacher greets at the door |
| 4–14 | Explicit modelling of one skill; choral or paired retell |
| 14–28 | Differentiated practice: core task, support version with frames/audio, extension task |
| 28–35 | Independent writing or exit ticket |
| 35–40 | Collect exit tickets, close, hand out materials |
Week 1 is spent teaching the routines explicitly, not assuming them: the signal for silence, materials routine, noise level for pair work, and what to do when stuck (ask two peers, then the teacher). The two students get a private cue card and a two-minute check-in at the start, not a public confrontation. Two positive phone calls home in week 1.
Week 2 adds roles in pair work (reader, recorder, reporter) and a simple points chart for on-task intervals rather than for misbehaviour.
Visible evidence for the supervisor: the routine chart on the wall, a laminated timer in use, the exit-ticket tracker with three weeks of results, three work samples at different levels, and a one-page log of the call-out baseline and what changed.
3. A senior colleague advises: 'Write all 42 names on the board and erase a minute of break for each infraction - punish the group until they police each other.' Evaluate this advice.

It fails on several grounds.
- It punishes students who did nothing. Collective sanctions violate procedural fairness, and adolescents respond to perceived injustice with more, not less, disengagement.
- It does not teach the target behaviour. No student learns what to do in the last 15 minutes; they learn only to avoid the teacher.
- It strengthens the escape function. Students who are already avoiding a too-hard or too-easy task now have a new reason to disengage.
- It is administratively unworkable. Erasing 42 names accurately while teaching is impossible, so the sanction becomes arbitrary and eventually collapses - which teaches that threats are empty.
- It carries risk under the school's discipline policy, which is framed around corrective and formative measures; an unsanctioned group punishment can become a complaint from parents.
What to use instead. If a group contingency is used at all, make it positive and achievable: the class earns minutes of a preferred activity for every 10-minute block with fewer than three call-outs, with the criterion set so that the class succeeds on day one. Keep individual accountability for the two instigators separate and private. And keep the primary intervention where the data point: the task design in the final segment.
