Background: Children who are learning English as an Additional Language (EAL) may start school with smaller vocabularies than their monolingual peers. Given the links between vocabulary and academic achievement, it is important to evaluate interventions that are designed to support vocabulary learning in this group of children.
Aims: To evaluate an intervention, namely Sign-Supported English (SSE), which uses conventionalized manual gestures alongside spoken words to support the learning of English vocabulary by children with EAL.
