Interactive Groups are an effective form of classroom organisation, capitalizing on peer interaction and community involvement to improve learning outcomes and wellbeing. Students are organised into small heterogeneous groups, each supported by an adult volunteer who ensures equitable participation and maximizes opportunities for dialogic interactions among peers, helping and supporting each other. Interactive Groups can be used for any school subject, and require no additional resources from the school. The human resources available are distributed to support all students included in the regular classroom.
