Academic performance of K-12 students in North America could be improved in that the majority of students produce undistinguished results in every international assessment of academic proficiency. The purpose of this study was to investigate whether student's self-discipline and parental involvement in student's academic activities have any impact…

Acadience Reading (AR) is a screener for early detection of reading problems in elementary students. Limited research exists, however, on its technical adequacy for evaluation of English Learners (ELs). In this study, we tested the long-term predictive validity and diagnostic accuracies of AR and examined the differences between native…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

The provision of high-quality early mathematics instruction and intervention is critical to ensure that all students are on track for academic success. Given this, identifying and utilizing assessments that can enable the detection of nonresponse to mathematics instruction is a critical aspect of early intervention. To this end, the current study…

In this large-scale study of students from Title 1 schools (N = 14,773), we used multiple-group latent change score (LCS) modeling to investigate the developmental relations between vocabulary knowledge and reading comprehension in students with a school-identified learning disability (LD; n = 627) and typically developing students (n = 14,146).…

This technical report is an addendum to a study we initially reported on in 2014 (Wray, Lai, Saez, Alonzo, & Tindal, 2014). In response to a request for additional analyses, in particular reporting confidence intervals around the results, we re-analyzed the data from the Wray et al study. This supplementary report presents the results of the…

This review examined the relations between grit and academic achievement based on a meta-analysis of 137 studies yielding 156 dependent samples (N = 285,331). Using the robust variance estimation, we found that the correlations of overall grit level with academic achievement were generally weak to moderate (weighted r = 0.19). The correlation of…

Multiple, simultaneous stressors in the family context during early childhood may compromise healthy adjustment to school, with potential long-term implications. Moreover, stressors across multiple contexts (e.g., home and school) can exacerbate the negative influences of stress on children's functioning. We investigated associations between…

Because schools often do not begin formal processes to identify students with gifts and talents until the third grade, many kindergarten through second-grade teachers face challenges in identifying and meeting the needs of these learners. We examined gifted education plans from a sample of seven districts in and around the Charlotte, North…

This Study Snapshot highlights key findings from a study that examines full-day kindergarten (FDK) implementation in Oregon. The evidence base on FDK is generally positive for short-term effects and unclear for longer-term effects, with some prior research associating FDK with gains in student outcomes such as grade 3 math and reading standardized…

This study examined the role of initial skill in moderating intervention effects of a 50-lesson mathematics intervention program, ROOTS, for at-risk kindergarten students focused on developing whole-number concepts and skills. The study utilized a randomized block design with at-risk students (n = 592) within classrooms (n = 60) randomly assigned…

This research responds to the call by early childhood educators advocating for more challenging mathematics curriculum at the primary level. The kindergarten Project M[superscript 2] units focus on challenging geometry and measurement concepts by positioning students as practicing mathematicians. The research reported herein highlights the…

Since March 2020, COVID-19 has required the implementation of remote learning options in K-12 public schools across North Carolina, ranging from fully online classroom experiences to hybrid scenarios in which students attend school both in person and remotely. In some locales, students continue to attend school in person most of the time, but with…

Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…

This study examines the long-term effects of a home visiting program, Home Instruction for Parents of Preschool Youngsters, on students from mostly low-income, Latino families (n = 254). Children who were in the home visiting program during their early years were compared with a similar demographic group who participated in prekindergarten in the…
