The problem
Intervention: Irie Classroom Toolbox - a teacher-training programme comprising an initial 5-day workshop followed by monthly hour-long in-classroom follow-up sessions over 8 months, designed to teach teachers positive discipline techniques and reduce use of violence
Who it was tested with: Pre-primary school teachers (aged 3-6 years) in Kingston, Jamaica; 105 teachers in intervention group, 85 in control group.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"The intervention is explicitly teacher-focused and aims to help teachers to gain skills, motivation, and opportunity to use positive discipline techniques. Teachers are supported via an initial 5-day workshop, and monthly hour-long, in-classroom, follow-up sessions over 8 months." The design represents a rigorous experimental approach with blinded assessment and randomization to test whether structured teacher training can reduce violence in early childhood settings.
The commentary does not provide full details of the trial methodology, sample sizes by school cluster, statistical significance levels, or long-term follow-up beyond 12 months. Measurement challenges are acknowledged, including bias from direct observation and potential underreporting in self-report measures.
