Phonological awareness and language intervention in preschoolers from low socio‐economic backgrounds: A longitudinal investigation

This study examines the literacy outcomes for children from socially disadvantaged backgrounds who had received specific whole‐class phonological awareness (PA) and language intervention in preschool. The participants were 57 children who had been involved in the original intervention study. Their PA skills, letter‐sound knowledge, real word and non‐word spelling and reading comprehension were assessed in Grade 2. The results indicated that children who had received intervention in preschool performed similarly to the children who had not received intervention. The gains made in PA and language skills post intervention had failed to augment further literacy development. A post hoc examination of individual student profiles, however, revealed that a subgroup of children who had received intervention had maintained their enhanced performance and that the intervention cohort had similar scores on tests of PA ability to their age‐matched peers in the population. It was concluded that whole‐class, teacher‐delivered, PA and language intervention, while effective in the short term, does not lead to a generalized improvement in literacy skills in Grade 2. Possible reasons for the failure of the program to produce medium term gains are discussed.
