Objective: A synthesis of evidence discussing the effectiveness of language and literacy interventions in children with English as an additional language. Our key research questions were: 1) What intervention studies have been published since 2014 addressing the language and literacy development of children with English as an additional language? 2) What is the impact of those interventions? We sought to update a 2015 systematic review evaluating language and literacy outcomes for EAL children (Murphy & Unthiah, 2015) with current intervention studies and to see which of those interventions could be adapted for classrooms in the UK. Methods: Four databases were searched; PsychInfo, British Education Index, Education Resources Information Center and Web of Science. Only peer reviewed journal articles published between 2014 and 2017 and written in English were included. The population tested were children of school age with English as an Additional Language who were classed as typically developing. All interventions had language or literacy as an outcome. Data was extracted using a standardised form and quality was assessed through a risk of bias analysis. From this screening process, 26 studies were eligible for inclusion in the current review. Key Findings: Explicit vocabulary instruction and targeted oral language practise 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 preteaching of vocabulary, embedded definitions into the text, or post-reading reinforcement activities. Voice recognition software appears promising, as demonstrated in three interventions with small to medium effects on reading fluency and comprehension. There is a lack of interventions taking place in the UK. There is a lack of interventions for adolescents, especially those in upper secondary school (ages 14-18). More interventions targeting continued professional development for teachers are recommended. Conclusions: Children with English as an additional language can benefit from targeted interventions. Suggestions are made as to how the most beneficial interventions could be replicated in the UK. Limitations: Limitations include a variability in terms of the rigour of intervention methodologies, leading to a high risk of bias and inconsistent effect sizes for several studies in this report. A proportion of successful interventions used the child's first language to aid learning. Such interventions might not be replicable in the UK, where classrooms typically feature children from a very large number of different home languages.
