Preschool morphological training produces long-term improvements in reading comprehension

Abstract We evaluated the effect of morphological awareness training delivered in preschool (8 months before school entry) on reading ability at the end of grade 1 and 5 years later (in Grade 6). In preschool, one group of children received morphological awareness training, while a second group received phonological awareness training. A control group followed the ordinary preschool curriculum. The comparison between each training condition and the control condition is quasi experimental, whereas the comparison between the morphological and phonological treatments is randomized at group level. In Grade 1 children in the morphological awareness training group had significantly higher scores than children in the control group on both word reading and text reading measures, but no differences were found between the experimental groups. In Grade 6 children in the morphological awareness training group had significantly higher scores compared with the control group on a latent measure of reading comprehension, whereas the children in the phonological awareness training group did not differ from the controls; although the experimental groups did not differ significantly from each other. The results suggest that early training in morphological awareness can have long-term effects on children’s literacy skills

Is there a direct relation between the development of vocabulary and grammar?

Previous studies of individual differences have revealed strong correlations between children's vocabulary and grammatical abilities, and these data have been used to support theoretical accounts positing direct developmental relations between these two areas of language. However, between‐person differences do not necessarily reflect intra‐individual dynamics. Thus, in the present study, we analysed longitudinal data from three annual assessments of vocabulary and grammar in 217 children (Mage = 4 years and 3 months at first assessment) using a modelling strategy with some utility in distinguishing relations at the between‐ and within‐person levels. The results revealed strong correlations between grammar and vocabulary at the between‐person level, but the evidence of direct dependencies between the variables at the within‐person level was rather limited. Specifically, we found a small direct contribution from grammar to vocabulary for children between the ages of 4 and 5, but there was no evidence of any direct contributions from vocabulary to grammar. Further analyses suggested that the home literacy environment may represent a common source of individual differences in children's vocabulary and grammatical skills. In light of these results, we argue that the evidence of direct relations between vocabulary and grammatical development in preschool‐aged children may not be as strong as previously assumed

Preschool phonological, morphological and semantic skills explain it all: Following reading development through a 9-year period.

Background There is increasing recognition of the contribution of morphological skills to the development of reading fluency. However, theoretical models and recent research raise questions about how different language skills influence reading development. Methods The present study was designed to follow the reading development of a large sample of Norwegian children (N = 323) from preschool to Grade 9, assessing their performance on a wide range of language‐related and reading skills including morphological awareness. We employed confirmatory factor analyses of the cognitive, linguistic and reading variables prior to modelling the contribution of the preschool language variables to reading comprehension in Grades 1, 2 and 9. Results Preschool measures of phonological, morphological and semantic skills were best represented by a single language latent variable. Reading in Grades 1 and 2, assessed by measures of both decoding and comprehension, was also best represented by a single latent variable. Preschool language skills have long‐range direct and indirect effects on the development of reading comprehension. Overall, preschool language abilities accounted for 69.2% of the variance in reading comprehension 9 years later. Conclusions The results demonstrate the powerful influence of early language on later reading and suggest that language intervention programmes, combining phonological, morphological and semantic activities, may help to reduce the incidence of reading problems

Lexical Quality Matters: Effects of Word Knowledge Instruction on the Language and Literacy Skills of Third- and Fourth-Grade Poor Readers

The purpose of this study was to explore the hypothesis that teaching students knowledge of word forms and meanings supports the development of decoding and linguistic comprehension, which are fundamental components of reading comprehension. We examined this hypothesis by investigating the effects of a comprehensive word knowledge intervention on the language and literacy skills of poor readers. The participants included 118 monolingual third- and fourth-grade students from 12 Norwegian elementary schools. A quasi-experimental approach was employed with students in the treatment and control groups matched on grade and reading comprehension level. The intervention was delivered by teachers in small groups for 60 minutes three times per week over a period of 10 weeks. At the end of the intervention, the treatment group showed significantly greater gains than the control group on researcher-created and transfer measures of language and a transfer measure of reading comprehension. There were no statistically significant effects of the intervention on two measures of decoding. The results support the hypothesis that comprehensive word knowledge instruction is effective in improving language abilities underpinning reading comprehension. The utility of this approach for improving decoding abilities remains unclear.

Sentence repetition is a measure of children’s language skills rather than working memory limitations

Sentence repetition tasks are widely used in the diagnosis and assessment of children with language difficulties. This paper seeks to clarify the nature of sentence repetition tasks and their relationship to other language skills. We present the results from a 2-year longitudinal study of 216 children. Children were assessed on measures of sentence repetition, vocabulary knowledge and grammatical skills three times at approximately yearly intervals starting at age 4. Sentence repetition was not a unique longitudinal predictor of the growth of language skills. A unidimensional language latent factor (defined by sentence repetition, vocabulary knowledge and grammatical skills) provided an excellent fit to the data, and language abilities showed a high degree of longitudinal stability. Sentence repetition is best seen as a reflection of an underlying language ability factor rather than as a measure of a separate construct with a specific role in language processing. Sentence repetition appears to be a valuable tool for language assessment because it draws upon a wide range of language processing skills

The profile of social functioning in children with Down syndrom (The Down Syndrome LanguagePlus-project)

Background: Practitioners and researchers have asserted for decades that social functioning is a strength in children with Down syndrome (DS). Nevertheless, some studies have concluded that children with DS may be at greater risk of impaired social functioning compared to typically developing controls. This cross-sectional study explores the profile of social functioning (social capabilities and social problems) in six-year-old children with DS, compares it with that of typically developing children and reveals possible differences in predictors between groups. Method: Parental reports and clinical tests were utilized. Results: The children with DS had generally weaker social capabilities compared to nonverbal mental age-matched controls, but no significant differences were found for social interactive play, community functioning and prosocial behaviour. No significant differences in predictors for social capabilities between the groups were found. The children with DS had more social problems than the typically developing controls with a similar chronological age and those with a similar nonverbal mental age, but no significant differences in emotional symptoms were found between the children with DS and either comparison group. Vocabulary was a more important predictor of social problems in the children with DS than in the typically developing control groups. Conclusion: Interventions for children with DS should strongly focus on integrating vocabulary skills and social functioning starting at an early age.

The advantages of jointly considering first and second language vocabulary skills among emergent bilingual children

This cross-sectional study investigated first (L1) and second (L2) language receptive and expressive vocabulary in a sample of 542 typically developing bilingual children of immigrants (age range 6–13), coming from six different L1 backgrounds in Norway. Results demonstrated that children’s L1 and L2 vocabulary skills increased with age. From a deficit perspective, the study confirms that in each age group, there is a vocabulary gap between the ranges of Norwegian vocabulary known by Norwegian monolinguals and by Norwegian L2 children. At the same time, when an additive, conceptual scoring approach (taking into account bilingual children’s known L1 and/or L2 vocabulary) was used, the persistent gap in vocabulary knowledge diminished or disappeared altogether. This finding is most evident in older age groups. Conceptual scoring provides a more sensitive and positive picture of bilingual children’s overall range of vocabulary. The findings demonstrate a need for more nuanced assessment procedures of semantic knowledge across children’s’ L1 and L2

Preschool Predictors of Later Reading Comprehension Ability : A Systematic Review

The objective for this systematic review is to summarize the best available research on the correlation between preschool predictors related to reading and later reading comprehension ability. The review aims to answer the following questions: 1) What is the magnitude of the correlation between linguistic comprehension skills in preschool and later reading comprehension abilities? 2) To what extent do phonological awareness, rapid naming, and letter knowledge correlate with later decoding and reading comprehension skills? Do these variables contribute uniquely to reading comprehension after linguistic comprehension skills in preschool have been taken into account? 3) To what extent does working memory in preschool correlate with later reading comprehension abilities, and does this have an impact beyond linguistic comprehension skills? 4) To what degree do other possible influential variables (e.g., age, test types) contribute to explaining any observed differences between the included studies
