The Dimensionality of Language Ability in Young Children

The purpose of this study was to empirically examine the dimensionality of language ability for young children (4-8 years) from prekindergarten to third grade (n = 915), theorizing that measures of vocabulary and grammar ability will represent a unitary trait across these ages, and to determine whether discourse skills represent an additional source of variance in language ability. Results demonstrated emergent dimensionality of language across development with distinct factors of vocabulary, grammar, and discourse skills by third grade, confirming that discourse skills are an important source of variance in childrens language ability and represent an important additional dimension to be accounted for in studying growth in language skills over the course of childhood.

Language, motor and cognitive development of extremely preterm children: Modeling individual growth trajectories over the first three years of life

UNLABELLED Survival rate of extremely low gestational age (ELGA) newborns has increased over 80% in the last 15 years, but its consequences on the short- and longer-term developmental competencies may be severe. The aim of this study was to describe growth trajectories of linguistic, motor and cognitive skills among ELGA children, compared to full-term (FT) peers, from the first to the third year of life, a crucial period for development. Growth curve analysis was used to examine individual and group differences in terms of initial status at 12 months and rate of growth through the second and the third year of life with five points of assessment. Twenty-eight monolingual Italian children, of whom 17 were ELGA (mean GA 25.7 weeks) and 11 were FT children, were assessed through the BSID-III at 12, 18, 24, 30 and 36 months for language skills and at 12, 24 and 30 months for motor and cognitive skills. ELGA children presented significantly lower scores than FT peers in language, motor and cognitive skills and they did not overcome their disadvantage by 3 years, even if their corrected age was taken into account. Concerning growth curves, in motor development a significant increasing divergence was found showing a Matthew effect with the preterm sample falling further behind the FT sample. In linguistic and cognitive development, instead, a stable gap between the two samples was found. In addition, great inter-individual differences in rate of change were observed for language development in both samples. Our findings highlight the theoretical and clinical relevance of analyzing, through growth curve analyses, the developmental trajectories of ELGA children in language skills taking into account their inter-individual variability also across motor and cognitive domains. LEARNING OUTCOMES After reading this article, the reader will interpret: (a) characteristics and growth trajectories of ELGA children from the first to the third year of life with respect to FT children in language, motor and cognitive development; (b) the method of growth curve analyses to describe group as well as inter-individual trajectories; (c) the rate of inter-individual variability in language as well as motor and cognitive skills, which gives useful indications for early interventions.

What are preschool teachers reading in their classrooms

The present study describes preschool read-alouds in terms of the types of texts to which children are exposed. The methods involved analyzing the genre and instructional foci of 426 titles read by 13 teachers throughout an entire academic year. Additionally, associations between teacher characteristics and texts teachers read in their classrooms were examined. Findings indicated that (a) narrative texts were the dominate genre read-aloud; (b) childrens exposure to alphabet books, nursery rhymes, books featuring math concepts, and multicultural content occurred at generally low rates; and (c) few significant associations exist between quantity of books read and teacher characteristics.

Impact of Professional Development on Preschool Teachers' Print References during Shared Read Alouds: A Latent Growth Curve Analysis.

Abstract This large-scale, experimental study aimed to (a) describe the extent to which teachers of preschool children at risk for reading difficulties make references to print during whole-class, shared-book read alouds and (b) empirically test the extent to which participation in professional development influences teachers’ frequency of references to print during shared read alouds across the academic year. Eighty-five preschool teachers working in targeted-enrollment preschool programs were randomly assigned to receive professional development aimed at increasing their use of print referencing or to a comparison condition involving alternative training; all teachers implemented a shared read aloud program in their classrooms. Implementation was documented via twice-monthly videotaping of shared read aloud sessions. Videos were coded for the frequency of print references and analyzed using latent growth curves. Despite considerable variability in teachers’ use of print referencing, findings showed sustained, meaningful changes in teachers’ use of print referencing with results favoring those who experienced the experimental professional development. Implications concerning effective professional development for supporting preschool childrens emergent literacy skills are discussed.

Uncorrected Hyperopia and Preschool Early Literacy: Results of the Vision in Preschoolers-Hyperopia in Preschoolers (VIP-HIP) Study.

PURPOSE To compare early literacy of 4- and 5-year-old uncorrected hyperopic children with that of emmetropic children. DESIGN Cross-sectional. PARTICIPANTS Children attending preschool or kindergarten who had not previously worn refractive correction. METHODS Cycloplegic refraction was used to identify hyperopia (≥3.0 to ≤6.0 diopters [D] in most hyperopic meridian of at least 1 eye, astigmatism ≤1.5 D, anisometropia ≤1.0 D) or emmetropia (hyperopia ≤1.0 D; astigmatism, anisometropia, and myopia <1.0 D). Threshold visual acuity (VA) and cover testing ruled out amblyopia or strabismus. Accommodative response, binocular near VA, and near stereoacuity were measured. MAIN OUTCOME MEASURES Trained examiners administered the Test of Preschool Early Literacy (TOPEL), composed of Print Knowledge, Definitional Vocabulary, and Phonological Awareness subtests. RESULTS A total of 492 children (244 hyperopes and 248 emmetropes) participated (mean age, 58 months; mean ± standard deviation of the most hyperopic meridian, +3.78±0.81 D in hyperopes and +0.51±0.48 D in emmetropes). After adjustment for age, race/ethnicity, and parent/caregivers education, the mean difference between hyperopes and emmetropes was -4.3 (P = 0.01) for TOPEL overall, -2.4 (P = 0.007) for Print Knowledge, -1.6 (P = 0.07) for Definitional Vocabulary, and -0.3 (P = 0.39) for Phonological Awareness. Greater deficits in TOPEL scores were observed in hyperopic children with ≥4.0 D than in emmetropes (-6.8, P = 0.01 for total score; -4.0, P = 0.003 for Print Knowledge). The largest deficits in TOPEL scores were observed in hyperopic children with binocular near VA of 20/40 or worse (-8.5, P = 0.002 for total score; -4.5, P = 0.001 for Print Knowledge; -3.1, P = 0.04 for Definitional Vocabulary) or near stereoacuity of 240 seconds of arc or worse (-8.6, P < 0.001 for total score; -5.3, P < 0.001 for Print Knowledge) compared with emmetropic children. CONCLUSIONS Uncorrected hyperopia ≥4.0 D or hyperopia ≥3.0 to ≤6.0 D associated with reduced binocular near VA (20/40 or worse) or reduced near stereoacuity (240 seconds of arc or worse) in 4- and 5-year-old children enrolled in preschool or kindergarten is associated with significantly worse performance on a test of early literacy.

Children with Communication Impairments: Caregivers' and Teachers' Shared Book-Reading Quality and Children's Level of Engagement.

This study addressed two aims: First, to examine the quality of adult shared book-reading behaviors for teachers and caregivers of children with communication impairments (CI) and, second, to compare the level of child literacy engagement during the teacher-led (group) and caregiver-led (one-on-one) shared book-reading sessions. Sixteen children with communication impairments were observed in both teacher-led and caregiver-led book-reading sessions using four matched manipulative storybooks. Children were observed during the fall and the spring of their preschool year. The quality of book-reading was evaluated using the ‘systematic assessment of book reading’ (SABR). Children’s level of literacy engagement was documented using the Children’s Orientation to Book Reading Rating Scale. Results indicated that teachers’ shared book-reading quality was significantly higher than caregivers’. Children’s level of engagement was high across both adult-led contexts.

School-readiness profiles of children with language impairment: linkages to home and classroom experiences

BACKGROUND This study represents an effort to advance our understanding of the nature of school readiness among children with language impairment (LI), a population of children acknowledged to be at risk of poor academic achievement. The academic, social-emotional, and behavioural competencies with which children arrive at kindergarten affect the nature of their future educational experiences, and their overall academic achievement. AIMS To examine whether there are reliable profiles that characterize children with LI just prior to kindergarten entrance, and the extent to which profile membership is associated with characteristics of childrens homes and preschool experiences. Questions addressed were twofold: (1) To what extent are there reliable profiles of children with LI with respect to their school readiness? (2) To what extent is childrens profile membership associated with characteristics of their homes and preschool classrooms? METHODS & PROCEDURES Participants were 136 children with LI from early childhood special education classrooms. We utilized latent class analysis (LCA) to classify individuals into profiles based on individual responses on school readiness measures. We then used multilevel hierarchical generalized linear models to examine the relations between profile membership and childrens home/classroom experiences. OUTCOMES & RESULTS LCA analyses revealed that a four-profile solution was the most appropriate fit for the data and that classroom experiences were predictive of these profiles, such that children in classrooms with more instructional/emotional support were more likely to be placed in profiles characterized by higher school readiness skills. CONCLUSIONS & IMPLICATIONS These results suggest that the school readiness profiles of young children with LI are associated with the quality of childrens classroom experiences, and that high-quality classroom experiences can be influential for ensuring that young children with LI arrive in kindergarten ready to learn.

Methodological Review of the Quality of Reach Out and Read Does It “Work”?

A considerable percentage of American children and adults fail to learn adequate literacy skills and read below a third grade level. Shared book reading is perhaps the single most important activity to prepare young children for success in reading. The primary objective of this manuscript was to critically review the methodological quality of Read Out and Read (ROR), a clinically based literacy program/intervention that teaches parents strategies to incorporate while sharing books with children as a method of preventing reading difficulties and academic struggles. A PubMed search was conducted. Articles that met three criteria were considered. First, the study must be clinically based and include parent contact with a pediatrician. Second, parental counseling (“anticipatory guidance”) about the importance of parent-child book reading must be included. Third, only experimental or quasi-experimental studies were included; no additional criteria were used. Published articles from any year and peer-reviewed journal were considered. Study quality was determined using a modified version of the Downs and Black (1998) checklist assessing four categories: (1) Reporting, (2) External Validity, (3) Internal Validity—Bias, and (4) Internal Validity—Confounding. We were also interested in whether quality differed based on study design, children’s age, sample size, and study outcome. Eleven studies met the inclusion criteria. The overall quality of evidence was variable across all studies; Reporting and External Validity categories were relatively strong while methodological concerns were found in the area of internal validity. Quality scores differed on the four study characteristics. Implications related to clinical practice and future studies are discussed.

School Readiness of Children with Language Impairment: Predicting Literacy Skills from Pre-Literacy and Social-Behavioural Dimensions.

BACKGROUND School readiness generally captures the notion that children do best when they arrive at formal schooling with a certain threshold of skill that will help them thrive in the classrooms academic and social milieu. AIMS To examine the dimensionality of the construct of school readiness among children with language impairment (LI), as well as the extent to which these dimensions relate to childrens end-of-kindergarten literacy skills. METHODS & PROCEDURES Participants were 136 preschool-aged children with LI. Children were assessed on measures of pre-literacy, social, and behavioural skills in preschool and reading and spelling in kindergarten. OUTCOMES & RESULTS Confirmatory factor analyses indicated that school readiness for this sample of children with LI is best characterized as two dimensions: pre-literacy and socio-emotional. Of the two dimensions, pre-literacy readiness was predictive of childrens future performance in reading and spelling. CONCLUSIONS & IMPLICATIONS The results further our theoretical understanding of the dimensions of school readiness, as well as our knowledge of how these skills are related among children with LI. Identifying domain-specific readiness skills that are predictive of kindergarten success can help to identify means of early assessment and targets for speech-language intervention.

The dimensionality of Spanish in young Spanish–english dual-language learners

PURPOSE This study examined the latent dimensionality of Spanish in young Spanish-English dual-language learners (DLLs). METHOD Two hundred eighty-six children participated. In their prekindergarten year, children completed norm-referenced and experimental language measures in Spanish requiring different levels of cognitive processing in both receptive and expressive language modalities. RESULTS The best-fitting model suggested a bifactor solution with a single general language factor L plus two additional factors word knowledge and integrative language knowledge. The general trait L reflects the proportion of common item variance for all of the items, and the group traits of word knowledge and integrative language knowledge explain additional domain-specific variance for those item subsets. CONCLUSION Results suggest that the Spanish language in preschool-age Spanish-English DLLs is not separable into content, form, and use, nor is it separable by higher- and lower-level language domains or processing demands. Instead it appears that a general language factor underlies oral language in Spanish in DLL preschoolers and that other factors account for additional variance over and above L. Findings are discussed in relation to a companion study of monolingual English-speaking prekindergarteners.
