Children with low performance in early numeracy are at risk of facing learning difficulties in mathematics, but few trials have examined how this can be ameliorated. A total of 120 first-grade children (M[subscript age] = 6.4 years) were randomly assigned to an intervention or a control condition. The 14-week intervention targeted early numeracy skills and was delivered in small groups three times a week. Immediately after the initial 8-week intervention phase, moderate and positive effects were found on early numeracy (d = 0.19), word problem solving (d = 0.41), and approximate number sense (d = 0.35). However, only the effects on word problems were significant, and all effects disappeared after the children undertook a second 6-week intervention phase. Overall, results indicate that (a) early numeracy skills are malleable in low-performing children, but (b) frequent and long-term interventions are needed for the positive effects to last.

Bilingualism appears to be related to poor language and reading comprehension in the instructional language (L2). However, in the long term, an early age of second language acquisition (AoA) may produce higher levels of second language skills than a later onset of L2 exposure. Most studies on school-aged second language learners (L2 learners) include children with 3-7 years of second language (L2) exposure. We compared 91 early bilingual (Norwegian and a variety of different native languages) 5th graders with 196 monolingual peers on a range of linguistic skills and their relationships with reading comprehension. All bilingual learners in the sample had been exposed to the instructional language by at least the age of 2. The results, using structural equation modelling and latent variables, show that early bilingual learners' vocabulary, listening comprehension, and reading comprehension are significantly lower than those of monolingual learners. Nevertheless, they have similar levels of knowledge of conjunctions and decoding skills and corresponding predictive patterns from linguistic skills to reading comprehension. We discuss the implications of the findings.

Knowledge about the smallest meaningful units of language, morphemes, is crucial for vocabulary and reading comprehension. This meta-analysis of 43 studies examined differences in morphological knowledge in the societal language between language-minority and language-majority children. There was a moderate to large mean group difference in morphological knowledge in favor of the language-majority children. Studies that examined inflectional knowledge (walk-walked, rose-roses) reported larger differences than studies that examined knowledge of derivations (coexist, serious) and compounds (bluebird, highlight). Studies that used oral tests and tests of expressive language reported larger differences than studies that used written tests and tests of receptive language. These findings show that morphology is an area of weakness in language-minority children. Paired with the evidence that morphological instruction improves general language ability and reading comprehension, the results suggest that morphology could be an essential component in language interventions for language-minority children.

Listening comprehension involves the ability to understand and extract meaning from spoken sentences, stories, and instruction. This skill is vital for young children and has long-term effects on school achievement, employability, income, and participation in society. There is a lack of measures of young children's listening comprehension skills. We report on a new measure of listening comprehension (LURI) that we tested in a group of at-risk preschoolers. Using IRT (Item Response Theory) analysis, we examined the psychometric properties of the instrument. Moreover, in a series of regressions, we found that the LURI measure predicted a range of other language skills better than standardized measures. Thus, the LURI test is a reliable and valid measure of listening comprehension. Assessing listening comprehension is a time-effective way of measuring a skill critically important to language development and represents the product of a range of different oral language processes.

This paper describes a randomised control trial (RCT) of a small group intervention targeting articulatory consciousness in first graders with a reading delay (control condition: n = 57, intervention condition: n = 64). The programme in the intervention condition consisted of basic decoding and spelling tasks using articulatory cards to symbolise speech sounds. Training took place four times per week for five weeks. The control condition received "business as usual". The results show that the children in the intervention condition learned to use the articulatory symbols, but there were no effects of the intervention on reading and phonological awareness measures. Also, there was no relationship shown between initial phonological awareness skills and gains, or lack thereof, from the intervention.

This study evaluates the effect of an intervention whose aim is to make articulatory consciousness a tool in decoding and spelling. The sample comprises 11 students with severe dyslexia (2 "SD" below the mean pseudoword scores), and the intervention programme consists of 32 individual sessions over 8 weeks. The study applies a multiple baseline/probe design with five baseline tests that correspond to a control condition, eight tests during the intervention and five post-intervention tests. On average, the results show significant improvement in all reading and spelling outcomes. However, there were also significant effects on an irrelevant control task (the pegboard test), perhaps indicating testing effects on the dependent variables, making it difficult to draw firm conclusions from the study. Consequently, testing the intervention in randomised trials of children with severe dyslexia is recommended to draw more firm conclusions about its efficacy for this group.

We examined the concurrent relationship between narrative skills (the Renfrew Bus Story Test) and core language measures (vocabulary, grammar and verbal memory) at age 4 and the longitudinal relationship between core language and listening comprehension skills at age 7 in a sample of 215 children using latent variables and structural equation modelling. Our main purpose was to investigate to what extent narrative retell constitutes a unique influence on later language and listening comprehension skills. The results support a two-factor model of narrative retelling and core language representing different but related constructs at age 4. Narrative retell explained unique variance in later language skills but did not explain additional variance beyond the 58% explained by the age 4 language construct. Similarly, narrative retell predicted unique variance in later listening comprehension, but not beyond what was explained by core language skills at age 4. The strength of the relationship between narrative retelling at age 4 and the age 7 measures was not related to the level of narrative skills. The results indicate that age 4 traditional core language measures capture more of the skills that are important for later language and listening comprehension than narrative skills at the same age.

The simple view of reading proposes that the development of reading comprehension in early elementary school is best predicted by children's fluent decoding and oral language skills. Recent studies challenge this view and suggest that executive functions should also be included in this theoretical model; however, the empirical evidence is not strong enough to clearly support or refute this hypothesis. In this short-term longitudinal study, we used latent variables to test whether executive functions have direct effects on the development of reading comprehension in 184 Romanian second graders, beyond fluent decoding and oral language skills. The results indicated that the initial stages of reading comprehension were associated with executive functions, but only the language skills could independently predict the development of reading comprehension. Our findings show that executive functions do not have a significant direct effect on the development of reading comprehension in early readers beyond fluent decoding and oral language skills in languages with transparent orthography. The results also suggest that once children learn to decode well, their language skills (and not their executive functions) have a strong effect on the development of reading comprehension. Therefore, reading interventions in elementary school should stress on the development of oral language skills.

Impaired procedural learning has been suggested as a possible cause of developmental dyslexia (DD) and developmental language disorder (DLD). We evaluate this theory by performing a series of meta-analyses on evidence from the six procedural learning tasks that have most commonly been used to test this theory: the serial reaction time, Hebb learning, artificial grammar and statistical learning, weather prediction, and contextual cuing tasks. Studies using serial reaction time and Hebb learning tasks yielded small group deficits in comparisons between language impaired and typically developing controls (g = -0.30 and -0.32, respectively). However, a meta-analysis of correlational studies showed that the serial reaction time task was not a reliable correlate of language-related ability in unselected samples (r = 0.03). Larger group deficits were, however, found in studies using artificial grammar and statistical learning tasks (g = -0.48) and the weather prediction task (g = -0.63). Possible reasons for the discrepancy in results from different tasks that all purportedly measure procedural learning are highlighted. We conclude that current data do not provide an adequate test of the theory that a generalized procedural learning deficit is a causal risk factor for developmental dyslexia or developmental language disorder.

Background: Children with speech sound difficulties often require educational psychology services, yet systematic reviews examining the association between these difficulties and language or reading problems are lacking. This metaanalysis examines whether these children are at higher risk of language and reading difficulties compared to their peers. Method: The study analyzed 290 effect sizes from cross-sectional and longitudinal studies that compared language and reading skills between children with speech sound difficulties and controls. Additionally, we evaluated 37 effect sizes from correlational studies in general populations to examine the relationship between speech sound skills and language or reading skills. Results: Children with speech sound difficulties showed significant concurrent language (Hedges' g = --0.60) and reading (Hedges' g = --0.58) problems. Correlational studies also demonstrated a relationship between speech sound skills and language (r = .23) and reading (r = .23) skills. Phonological awareness and study quality were significant moderators. Longitudinal studies showed persistent or increasing group differences over time in language (Hedges' g = --0.85) and reading (Hedges' g = --0.50). These findings were consistent regardless of the severity or types of speech sound difficulties, nonverbal IQ, country, age, and publication year. However, a precision-effect test and the precision-effect estimate with standard errors analysis suggested a potential decrease in effect size due to publication bias from small sample sizes in primary studies. Conclusion: Children with speech sound difficulties are at an increased risk of language and reading difficulties, emphasizing the need for broader language assessments and early interventions to mitigate future academic difficulties.

This study investigated the psychometric properties of the Early Numeracy Screener. The Early Numeracy Screener is a teacher-administered, paper-and-pencil test measuring counting skills, numerical relational skills, and basic arithmetic skills. Three hundred and sixty-six first graders took the Early Numeracy Screener at the beginning of the school year. Confirmatory factor analysis was conducted in order to examine whether the screening tool was identified as a one-factor model or a three-factor model. The confirmatory factor analysis found evidence for the three-factor model, establishing construct validity. Evidence for criterion-related validity was found in crosstabulation and correlation with the national test measuring overall mathematics performance taken towards the end of the school year. The Early Numeracy Screener may serve as an indicator of young children's performance in early numeracy. The brevity and ease of use of the Early Numeracy Screener make it suitable for classroom instructional settings.

While we know that interventions targeting oral language can be effective, little is known about what drives these effects. In this study, we examine whether gains in transfer measures are mediated through the specific words that are trained in a language intervention. Based on a large-scale randomized controlled trial of language intervention in 4- to 5-year-old children, latent mediation models were used to disentangle oral language gains in transfer measures. The results first showed that the effects of the language intervention and the transfer effects are generated through expressive rather than receptive measures of language. Second, we found that the effects of the intervention on intermediate transfer measures of language were mediated through the ability to define the trained words. Third, and critically, for far transfer measures that did not contain any of the trained words, the effects were mediated through the trained words. The findings relate to theories of transfer and support the idea that far transfer is possible, at least within the same domain. In addition, it seems that effects on receptive language skills are difficult to obtain and that what is improved is instead the children's ability to express themselves and use procedures to explain words. Thus, to optimize intervention effects, future studies should focus on expressive language.

Studies have identified concurrent, longitudinal, and bidirectional associations between language difficulties and internalizing problems. This is commonly explained by social exclusion or withdrawal from peers, but underlying mechanisms are not well understood. This study uses sibling data to investigate if the comorbidity between language difficulties and internalizing problems is best explained by familial factors shared by siblings, such as genes or family environment, or nonfamilial factors specific to each child, such as peer environment. Data include 5,568 siblings at 5 years and 3,654 siblings at 8 years participating in the Norwegian Mother, Father and Child Cohort Study (MoBa). We constructed a latent factor model at 5 and 8 years, including a family comorbidity factor capturing correlations between language and internalizing problems that were equally strong between as within siblings. Results showed that the correlation between one sibling's internalizing problems and the other sibling's language problems was mostly accounted for by a family comorbidity factor. The best-fitting longitudinal model included stability of the family comorbidity factor and stability of language and internalizing problems within each sibling and no cross-sibling or cross-trait longitudinal associations. This suggests that the association between language and internalizing problems may be best explained by family factors.

This protocol presents the plan for a systematic review that investigates the effect of oral language interventions for children with intellectual disability (ID), language disorder (LD), autism spectrum disorder (ASD), Down syndrome (DS), Williams syndrome (WS), and fragile X syndrome (FXS). Language development is a highly frequent area of difficulty for children within these diagnostic groups, and oral language interventions are therefore important. However, to provide better evidence-informed practice, what oral language interventions are effective and for whom needs to be investigated. The systematic review not only investigates the effect of oral language interventions targeted at specific disorders but also identifies interventions that may yield similar improvements in different neurodevelopmental disorders.

Children who begin school with proficient language skills are more likely to develop adequate reading comprehension abilities and achieve academic success than children who struggle with poor language skills in their early years. Individual language difficulties, environmental factors related to socioeconomic status (SES), and having the educational language as a second language are all considered risk factors for language and literacy failure. Intervention programs have been designed with the aim of supporting at-risk children's language skills. In these programs, the instructional methods typically include a strong focus on vocabulary instruction within the context of storytelling or text reading. Elements that directly activate narrative and grammatical development are often included. This Campbell systematic review examines the effects of linguistic comprehension instruction on generalized measures of language and reading comprehension skills. The review summarizes evidence from 43 studies, including samples of both preschool and school-aged participants.

Abstract Few studies have examined how socioeconomic status (SES) affects two essential parts of human development, namely vocabulary and reading comprehension, in children facing severe poverty. The Roma population is the largest minority group in Europe, the majority of whom live in severe poverty. This study compared the development of 322 Roma children with the development of 178 non-Roma children, between the ages of 7 and 10 years, living in Romania. The Roma children had poorer initial vocabulary and reading comprehension skills as well as slower growth rates for both compared to the non-Roma children. Importantly, SES had a direct influence on growth in both reading comprehension and vocabulary. The effect of SES was partly mediated by school absence and nonverbal IQ. This is a powerful finding since it suggests that poverty may have detrimental effects not only on reading but also on the development of verbal abilities.

The two major determinants of reading comprehension are language comprehension and decoding, but prior studies of the development of reading comprehension from an early age show inconsistent results. To clarify these inconsistencies we report a 6-year longitudinal study (starting at Age 4 years) where we control for measurement error and track the development and interrelationships between a range of predictors of reading comprehension (language, decoding, and cognitive skills). We found two main pathways to reading comprehension: a highly stable language comprehension pathway (reflecting variations in vocabulary, listening comprehension, grammar, and verbal working memory) and a less stable code-related pathway (reflecting variations in phoneme awareness, letter knowledge, and rapid automatized naming). Early language comprehension at Age 4 years is strongly related to code-related predictors (phoneme awareness, letter knowledge, and rapid naming), and influences decoding indirectly through these constructs. Early oral language skills predicted initial levels of reading comprehension and its growth between the ages of 7 and 9 years. Strikingly, language comprehension and decoding, together with their interaction and curvilinear effects, explain almost all (99.7%) of the variance in reading comprehension skills at 7 years of age. Our study adds to prior knowledge in several important ways and provides strong support for an elaborated version of the simple view of reading (Gough & Tunmer, 1986).

Purpose: This longitudinal study examined the contribution of preschool morphological awareness to word reading skills and reading comprehension, as well as to the developmental change of reading ability beyond other well-established oral language and cognitive predictors. A distinction was made between the domains of inflectional and derivational morphology. Method: Two hundred and fifty-nine Norwegian-speaking children (46% female) with a mean age of 5.5 years were assessed in preschool on language measures and again in Grades 1 and 3 on measures of word reading accuracy and fluency and in Grades 3 and 4 on reading comprehension. We fit latent change score models with preschool predictors using parceling to control for measurement error. Results: We found a unique contribution of preschool morphological awareness to reading comprehension in Grade 3, but no unique contribution to Grade 1 decoding. Neither awareness of inflections nor awareness of derivations predicted developmental change in word reading fluency between Grades 1 and 3 or change in reading comprehension between Grades 3 and 4 beyond the effect of control variables. Conclusion: Our findings confirm the relevance of morphological awareness only for early attainment in reading comprehension and highlight the importance of accounting for measurement error in studying associations among variables aiming to discover specific contributions.

Social functioning and reading proficiency are critical for success in school and society. Therefore, identifying children with such problems is important. This study had 2 parts: first, a random sample of 234 elementary schools was surveyed about which instruments they use to assess reading proficiency and social functioning. Second, a systematic review of the quality of these instruments was conducted using international standards for examining the quality of assessment instruments. The survey showed that schools more often assessed and had more instruments available for reading than for social functioning. The systematic review of the assessment instruments used revealed that the psychometric qualities of many was weak or undocumented, while the dimensions of test material quality were generally good. The findings demonstrate a need for a more thorough examination of the psychometric properties of assessment instruments to be used in school.

This study investigated the psychometric properties of the Elementary Social Behaviour Assessment (ESBA), a teacher-report measure of students' social skills and academic engagement adapted for use in Norwegian schools. At two times, 8 weeks apart, 151 teachers rated 793 students in Grades 1-6 on the ESBA and the Social Skills Rating System Teacher's form (SSRS-T). Exploratory factor analysis with the first assessment suggested one or possibly two factors. Confirmatory factor analysis with the second assessment confirmed the one- or two-factor models but did not offer strong evidence for one over the other. The ESBA demonstrated good to excellent reliability. Strong concurrent and predictive correlations with the SSRS-T established criterion validity. The school and teacher levels explained only a limited amount of the total variance in ESBA scores, suggesting that teachers rate students quite similarly. The Norwegian-adapted ESBA paralleled the reliability and validity evidence from US samples.

Background: Children with language comprehension difficulties are at risk of educational and social problems, which in turn impede employment prospects in adulthood. However, few randomized trials have examined how such problems can be ameliorated during the preschool years. Methods: We conducted a cluster randomized trial in 148 preschool classrooms. Our intervention targeted language comprehension skills and lasted 1 year and 1 month, with five blocks of 6 weeks and intervention three times per week (about 75 min per week). Effects were assessed on a range of measures of language performance. Results: Immediately after the intervention, there were moderate effects on both near, intermediate and distal measures of language performance. At delayed follow-up (7 months after the intervention), these reliable effects remained for the distal measures. Conclusions: It is possible to intervene in classroom settings to improve the language comprehension skills of children with language difficulties. However, it appears that such interventions need to be intensive and prolonged.

Second-language learners display poorer general language skills in the language used at school than their monolingual peers, which is a concern because general language skills (vocabulary, grammar, language expression, and comprehension) provide the foundation for later academic success. In a randomized controlled trial, we examined the efficacy of an intervention to improve second-language learners' general language skills in their second language. One hundred and fifteen children (mean age = 5.5 years) were randomly assigned to a business-as-usual control group or to an 18-week intervention program conducted by kindergarten teachers during the last semester of kindergarten. The children were assessed at pre-intervention, post-intervention and a seven-month follow-up. The children in the treatment group demonstrated significant improvements on a custom measure of taught vocabulary. The language intervention program also produced effects that generalized to standardized measures reflecting expressive language skills. These findings suggest that intervention programs designed to enhance second-language learners' expressive language in the second language can be successfully implemented in kindergarten settings before school entry.

This review aims to improve the understanding of intervention studies targeting two core constructs: linguistic comprehension and reading comprehension. Linguistic comprehension is defined as the process by which lexical (i.e., word) information, sentences and discourses are interpreted (Gough & Tunmer, 1986;). It refers to the ability to understand and express oral language, often assessed by tests of vocabulary or listening comprehension (Bornstein, Hahn, Putnick, & Suwalsky, 2014; Foorman, Herrera, Petscher, Mitchell, & Truckenmiller, 2015b; Klem et al., 2014, Melby-Lervåg & Lervåg, 2014). The primary aim of this review is to provide an overview of studies on interventions targeting linguistic comprehension and their effects on measures of generalized linguistic comprehension and/or reading comprehension. By strengthening the researchers knowledge of this subject, they can potentially obtain insight into how related deficits can be ameliorated. This information is critical in making policy decisions about whether such programs are suitable for implementation in early childhood education and later schooling. Reviewing training studies may also provide a more refined understanding of the underlying causal mechanisms through which interventions are effective. This aspect is vital for providing a sound theoretical foundation for constructing better and more targeted intervention programs. [For the systematic review, see EJ1266849.]

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 objective for this systematic review is to summarize the best available research on the correlation between reading-related preschool predictors and later reading comprehension ability. The findings in this planned review are of practical significance, as they have direct implications for how to best prepare children for reading instruction. Additionally, with early knowledge of the patterns of normal development, there is the potential to recognize the signs of delayed or divergent development. When a child show signs of poor language development additional efforts can be focused on with better certainty that will help prevent later struggles with reading. To recognize when a child displays signs of struggles with language risk factors or early reading ability, it is essential for research to provide important indications of the different language and environmental markers that can be predictors of later reading skills.
