Peer interaction offers critical learning opportunities for preschool students, yet exposure to peers of different skill levels varies within and across classrooms. We explore two ways peers may affect learning: differences in who children play with in a classroom and differences in student composition across classrooms. We find that playing with…

The simple views of reading (SVRs) and writing (SVWs) reflect useful frameworks for the psychoeducational evaluation of literacy difficulties. They describe reading comprehension and written expression as the outcome of oral language, decoding, and transcription skills. Prior research has demonstrated that these components explain the vast…

Within the context of the Direct and Indirect Effects Model of Writing (Kim & Park, 2019), we examined a dynamic relations hypothesis, which contends that the relations of component skills, including reading comprehension, to written composition vary as a function of dimensions of written composition. Specifically, we investigated: (1) whether…

Recent work has stressed the importance of considering child-level propensities and environmental opportunities when studying early math achievement; however, few studies investigate the interaction between these factors. This study examined whether children's inhibitory control moderates the association between parental math input and children's…

The neighborhood literature consistently documents associations between neighborhood socioeconomic status (SES) and child development. Yet, this approach may miss important heterogeneity in neighborhood resources (e.g., libraries, doctors' offices) that have important implications for children. Moreover, the mechanisms that explain the relation…

Decades of research on early care and education have shown that four-year-old children who enroll in prekindergarten (pre-K) programs start kindergarten scoring higher on assessments of academic skills than those who do not. A handful of long-term follow-up studies of pre-K have also found that these programs can have lasting beneficial impacts on…

The Tennessee Voluntary Pre-K Program (TN-VPK) is statewide full-day program that gives priority to children from low-income families. A regression-discontinuity design with a statewide probability sample of 155 TN-VPK classrooms and 5,189 children participating across two pre-K cohorts found positive effects at kindergarten entry with the largest…

Within the context of the Direct and Indirect Effects Model of Writing (Kim & Park, 2019), we examined a dynamic relations hypothesis, which contends that the relations of component skills, including reading comprehension, to written composition vary as a function of dimensions of written composition. Specifically, we investigated (a) whether…

Media use could be detrimental to children's language and literacy skills because it may displace other language-enhancing activities like shared reading and caregiver-child interactions. Furthermore, the extent to which children use media with adults (joint media engagement), the extent to which they use interactive media (apps/games), and the…

Self-regulation in early childhood is an important predictor of success across a variety of indicators in life, including health, well-being, and earnings. Although conceptually self-regulation has been defined as multifaceted, previous research has not investigated whether there is conceptual and empirical overlap between the factors that…

Media use is a pervasive aspect of children's home experiences but is often not considered in studies of the home learning environment. Media use could be detrimental to children's language and literacy skills because it may displace other literacy-enhancing activities like shared reading and decrease the quantity and quality of caregiver-child…

As individuals with intellectual or developmental disabilities (IDD) mature, it is important to train them not only in functional/vocational skills, but also to continue to develop their literacy skills. There is little conclusive information regarding what facilitates reading comprehension in this population. Some previous research indicates that…

Research Findings: The present study examined the transition practices reported by 59 pre-kindergarten (pre-k) and 186 kindergarten teachers in the rural Southeastern United States, and asked if transition practices related to skills at the beginning and end of kindergarten for 387 children. Analyses indicated kindergarten teachers offered more…

This study examined the associations of preschool children's executive function (EF) and learning behaviour (CLB) with their concurrent academic skills and the role of CLB as a mediator for the EF-academic skills link. One hundred seventy-nine children were assessed on EF and math and literacy skills. Parents and teachers completed a questionnaire…

This investigation examined patterns of codeveloping internalizing and externalizing problems from early childhood through adolescence (i.e., Grades 1 to 12). Subgroups of children with heterogeneous developmental trajectories (i.e., pure and co-occurring internalizing and externalizing problems) were identified and their long-term associations…
