A systematic review of language and literacy interventions in children and adolescents with English as an additional language (EAL)

This systematic review presents a synthesis of evidence regarding the effectiveness of language and literacy interventions targeting children with EAL. It updates the systematic review by Murphy and Unthiah [2015. A systematic review of intervention research examining English language and literacy development in children with English as an additional language (EAL). http://www.naldic.org.uk/Resources/NALDIC/Research and Information/Documents/eal-systematic-review-prof-v-murphy.pdf.], using the same methodology. Four databases were searched resulting in 2217 records identified. After screening 25 interventions, found in 26 studies, were eligible for inclusion. The results provide collective evidence that explicit vocabulary instruction and targeted oral language practice yield language gains for EAL learners, with a tendency for larger intervention gains in learners with the lowest initial pre-test scores. Shared reading interventions show positive effects when combined with the pre-teaching of vocabulary, embedded definitions into the text, or post-reading reinforcement activities. The review also highlights the paucity of interventions in the UK and in particular, a lack of interventions for adolescents, especially those in upper secondary school (ages 14-18).
