Exploring the relations between teachers' high-quality language features and preschoolers and kindergarteners' vocabulary learning.

This study explored the use of sophisticated vocabulary, complex syntax, and decontextualized language (including book information, conceptual information, past/future experiences, and vocabulary information) in teachers' instructional interactions with children during the literacy block in prekindergarten and kindergarten classrooms. The sample included 33 teachers and 421 children. We examined correlations among these language features and their unique contributions to children's vocabulary learning.

A Growth Mindset Message Leads Parents to Choose More Challenging Learning Activities.

Prior research has shown that the home learning environment (HLE) is critical in the development of spatial skills and that various parental beliefs influence the HLE. However, a comprehensive analysis of the impact of different parental beliefs on the spatial HLE remains lacking, leaving unanswered questions about which specific parental beliefs are most influential and whether inducing a growth mindset can enhance the spatial HLE. To address these gaps, we conducted an online study with parents of 3- to 5-year-olds.

Child effects and child care: Implications for risk and adjustment.

Evocative effects of child characteristics on the quality and quantity of child care were assessed in two studies using longitudinal data from the NICHD Study of Early Child Care. We focus on the influence of child characteristics on two important aspects of the child care experience: language stimulation provided by caregivers and quantity of care. In Study 1, associations between the developmental status of children aged 15 to 54 months and the language stimulation provided by their caregivers were examined using path models, and longitudinal child effects were detected across the earliest time points of the study.

Parental Writing Support and Preschoolers' Early Literacy, Language, and Fine Motor Skills.

The current study examines the nature and variability of parents' aid to preschoolers in the context of a shared writing task, as well as the relations between this support and children's literacy, vocabulary, and fine motor skills. In total, 135 preschool children (72 girls) and their parents (primarily mothers) in an ethnically diverse, middle-income community were observed while writing a semi-structured invitation for a pretend birthday party together. Children's phonological awareness, alphabet knowledge, word decoding, vocabulary, and fine motor skills were also assessed.

Longitudinal Relations Between Parental Writing Support and Preschoolers' Language and Literacy Skills.

Parental writing support was examined over time and in relation to children's language and literacy skills. Seventy-seven parents and their preschoolers were videotaped writing an invitation together twice during one year. Parental writing support was coded at the level of the letter to document parents' graphophonemic support (letter-sound correspondence), print support (letter formation), and demand for precision (expectation for correcting writing errors).

The Contributions of Parental Management Language to Executive Function in Preschool Children.

This study investigated relations between preschoolers' emergent executive function skills and their interactions with parents, with particular focus on the verbal utterances parents use to guide children's behavior (i.e., management language).

Relative Contributions of Pre-Kindergarten and Kindergarten to Children's Literacy and Mathematics Skills.

A difficulty for developmental researchers is disambiguating children's general maturation from the influence of schooling. In this study, we use a natural experiment to examine the influence of pre-kindergarten and kindergarten schooling experiences on the development of literacy and mathematics. Children (n = 60) whose birthdates fell within two months of the state-determined cut-off date for pre-kindergarten and kindergarten entry were administered four subtests of the Woodcock-Johnson Tests of Achievement III in the fall and spring of the school year.

Vocabulary learning in Head Start: Nature and extent of classroom instruction and its contributions to children's learning.

In the current study, we employed the 2006 cohort of the large-scale, nationally representative, Head Start Family and Child Experiences (FACES) dataset to construct a snapshot of vocabulary instruction and learning in high-poverty preschools. Specifically, we examined Head Start teachers' reports of the frequency of vocabulary instruction in their classrooms as well as the overall quality of their classroom instruction. We also explored the teacher- and center-level factors that predicted these dual aspects of instruction, and the role of that instruction in children's vocabulary development over the preschool year.

Conventional and piecewise growth modeling techniques: applications and implications for investigating Head Start children's early literacy learning.

This article reviews the mechanics of conventional and piecewise growth models to demonstrate the unique affordances of each technique for examining the nature and predictors of children's early literacy learning during the transition from preschool through first grade. Using the nationally representative Family and Child Experiences Survey (FACES) data set, 1997 cohort, the authors show how piecewise models revealed discrete contributions of child, family, and classroom experiences to children's literacy skills within particular years, whereas conventional models, which considered the whole 3-year trajectory of change as a single outcome, revealed fewer of these nuanced contributions.
