A research report published in the International Journal of Language and Communication Disorders investigates the effectiveness of teaching assistant (TA)-delivered narrative and vocabulary interventions to secondary school children with language difficulties.
Researchers at City University of London and University of Oxford conducted a randomised controlled trial in two outer London boroughs. Across 21 schools, 358 Year 7 underperforming pupils (mean age = 12.8 years) were recruited, and randomised to four groups within each school: vocabulary intervention, narrative intervention, combined narrative and vocabulary intervention, and delayed waiting control group. The narrative programme focused on the understanding and telling of stories, using a story structure to support story generation. Pupils were introduced to different types of stories (fictional, non‐fictional, scripts) and narrative genres. The vocabulary programme focused on developing key concepts and vocabulary items relevant to the curriculum (eg, nutrition) and age-appropriate (eg, careers). A variety of tasks including word associations, categorisation, mind‐mapping and word‐building were used to reinforce word learning.
The language and communication programmes (narrative, vocabulary, and combined narrative and vocabulary) were delivered by TAs in the classroom, three times per week, for 45–60 min each, over six weeks, totalling 18 sessions. Assessments were conducted pre- and post-intervention.
Overall, pupils in the intervention groups made greater improvements on standardised measures of narrative (effect size = +0.296), but not vocabulary skills, compared with control group children.
