All for one and one for all: The good inclusion game

Abstract The Good Inclusion Game (GIG) is a class‐wide education intervention employing interdependent group contingencies to increase inclusive behaviors between pupils with and without special educational needs (SEN). While previous research provided evidence of effectiveness when the class of children was split into two groups, it did not assess the effects of the GIG for one whole‐class group or in the long term. The present study addresses both of these issues. Using an ABAB design, results show a one‐team version of the GIG to be effective in increasing inclusive behaviors between pupils with and without SEN. Gains were maintained across time. Implications for inclusive education interventions and teacher training are discussed.
