The role of verbal working memory (VWM) in early language and literacy development among typical and atypical monolingual children exposed to different orthographies is well established. Less is known how English Language Learners (ELLs) allocate their VWM resources in early stages of literacy acquisition in English (L2). This study examined the…

Models are central to the practice and teaching of science. Yet people often fail to grasp how scientific models explain their observations of the world. Realizing the explanatory power of a model may require aligning its relational structure to that of the observable phenomena. The present research tested whether "relational…

General measures of process quality are widely used in the early childhood education (ECE) field. However, the evidence regarding associations between the most widely used process quality measure, the Classroom Assessment Scoring System (CLASS; Pianta et al., 2008), and children's school readiness gains during the preschool year is mixed. Using…

Alleviating disadvantage in low-income environments predicts higher cognitive abilities during early childhood. It is less established whether family income continues to predict cognitive growth in later childhood or whether there may even be bidirectional dynamics. Notably, living in poverty may moderate income-cognition dynamics. In this study,…

This study investigates whether age-related changes in the structure of 5 complex working memory (WM) tasks (a) reflect a general or domain specific system, (b) follows a similar trajectory across different age spans, and (c) contribute domain general or domain specific resources to achievement measures. The study parsed the sample (N = 2,471)…

Assessing English learners (ELs) in US schools is challenging because many widely used assessments have not been designed with ELs in mind. Yet if teachers are sensitive to how ELs may perform differently from native speakers on such assessments, these assessments reveal useful information about ELs' language and literacy skills. This mixed-method…

This study investigated the classification accuracy of the "Dynamic Indicators of Vocabulary Skills" (DIVS) as a preschool vocabulary screening measure. With a sample of 240 preschoolers, fall and winter DIVS scores were used to predict year-end vocabulary risk using the 25th percentile on the "Peabody Picture Vocabulary Test--Third…

The Adult Basic Education (ABE) population consists of a wide range of abilities with needs that may be unique to this set of learners. The purpose of this study was to better understand the relative contributions of phonological decoding and morphological awareness to spelling, vocabulary, and comprehension across a sample of ABE students. In…

There are currently 2 principal models of publicly funded prekindergarten programs (pre-K): targeted pre-K, which is means-tested, and universal pre-K. These programs often differ in terms of the economic characteristics of the preschoolers enrolled. Studies have documented links between individual achievement in school-age children and the…

Efficacy of an intensive reading intervention implemented during the nonacademic summer was evaluated in children with reading disabilities or difficulties (RD). Students (ages 6-9) were randomly assigned to receive Lindamood-Bell's "Seeing Stars" program (n = 23) as an intervention or to a waiting-list control group (n = 24). Analysis…

A classroom randomized trial (n = 31 classrooms) was conducted using the Second Step Early Learning (SSEL) curriculum compared to usual curricula. Head Start and community preschool classrooms enrolling low income children were randomly assigned to deliver SSEL (n = 16) or usual curricula (n = 15). Data are reported for four year olds…

This study investigated longitudinal pathways leading from early spatial skills in first-grade girls to their fifth-grade analytical math reasoning abilities (N = 138). First-grade assessments included spatial skills, verbal skills, addition/subtraction skills, and frequency of choice of a decomposition or retrieval strategy on the…

In this study, the relations among a range of literacy-related home practices and children's acquisition of language and literacy at the outset of preschool are examined in a sample of linguistically diverse children from low-income families in the United States. Specifically, the study focuses on sources of variation found in mother-child…

A substantial literature documents the benefits of early childhood education and formal preschool experiences on children's school readiness, with low-income and otherwise disadvantaged children benefitting the most from these programs. However, these academic benefits often fade out as children age, and most disappear by the end of kindergarten…

This research used prospective longitudinal data to examine the associations between first-grade teachers' over- and underestimation of their students' math abilities, basic reading abilities, and language skills and the students' high school academic performance, with special attention to the subject area and moderating effects of student…
