Lewis lists four main recommendations to minimize misbehaviour of students at risk. The teacher must stay calm. “A teacher who reacts to an attention-seeker with irritation and annoyance, to a power-seeking student with anger and exasperation, to a revenge-seeking student with fear or hurt, or to a withdrawing student with despair or helplessness, becomes part of the problem, not part of the solution.”
The teacher also must give encouragement according to effort rather than achievement, signalling the student is useful and an integral part of the class.
