Classroom intervention focusing on peer interaction persuades children to develop positive behaviour. Peer interaction plays a significant role in managing problem behaviour among adolescent children. It facilitates identifying weaknesses in children's justification for their problem behaviour. Thus, the study aimed to propose a classroom intervention based on meta-cognitive strategies to subdue problem behaviours among secondary school children. The activities were prepared to inoculate the three components of metacognitive skills--awareness, control and regulation. The study conducted on 36 secondary school children shows a positive change in the behaviour among students who have done the intervention. A quasi-experimental design is used for the study. Both quantitative and qualitative analyses of the data were done. A repeated measures ANOVA (RMA) indicated a significant effect on the outcome, p < 0.05. Post-intervention interview results showed students' interest in regulating their problem behaviours. The implication is that the proposed learner-centred class intervention can be part of the secondary school curriculum.
