The Fastest Worker in Class VII

The first change is to the task structure, not to Ravi. He finishes the exercises in half the time the class takes, which means the behaviour is being produced by an empty half-period; punishing him for what the lesson design causes is both unfair and ineffective, and it will confirm his view that school is a place where he is told off. The mother's complaint is real, but it is a symptom, and a public apology would address her anger while making Ravi's status in the class worse. So in the next period, every exercise set gets an extension task prepared before the lesson begins - a harder problem, a 'write the question this is the answer to', or a check-and-explain role - and Ravi is given the extension as a matter of routine, not as a reward. That single change removes the occasion for calling out. The conversation with Ravi comes after, not before, and it is about the laughing incident specifically, not about his character.

First, privately and briefly, name the specific behaviour and its effect on one named person: 'When you laughed on Tuesday, she stopped putting her hand up.' Do not ask for a confession or a promise; ask only that it not happen again. Second, give him a role that uses the speed: he prepares the board or holds the answer key for the last ten minutes, so that finishing early gives him status in a useful direction. Third, agree a private signal - a hand flat on the desk - meaning 'hold it', so that correction happens without an audience; the point of a signal is that it lets him self-correct, which a telling-off does not. Fourth, protect the girl: speak to her separately, do not call on her immediately after Ravi has called out, and let her see that the matter has been dealt with. Fifth, telephone her mother and report what you have done, not what Ravi is like. What I would not do is send him out of the class; he would return with more to prove.

The plan should not turn the top nine into unpaid teachers, which usually bores them and stigmatises the bottom nine. One structural device: every period begins with a ten-minute core task the whole class does, so no group is publicly labelled. The nine above 70 per cent get a parallel challenge set on the same concept rather than more problems of the same type - same topic, different demand. The nine below 35 per cent work with me at the board in a small group on the two or three prerequisite skills, not on the whole chapter, because their gap lies earlier than the current chapter. The middle 24 work in pairs on the standard exercises with a checklist that lets them mark their own work. Once a week, mixed pairs work on one problem that requires explaining, so the strong students explain a method as a one-off rather than serving as tutors for three weeks. The unit test will show whether the bottom group moved on the prerequisites; that, not syllabus completion, is what I would report to the headmistress.
