This study was to evaluate weight status and sociodemographic disparities in physical activity (PA) intensities (i.e., vigorous PA [VPA], moderate PA [MPA], and light PA [LPA]) during different segments of the school day, including physical education (PE), recess, and lunchtime. Participants were 287 third-grade students (Mage = 8.38, SD = 0.50).…

The current study tested changes in modern/contemporary art valuation among students ages 6-15. Participants rated abstract paintings and conceptual works (and two control categories--traditional Western figurative paintings and everyday objects) on the dimensions of liking and art classification. As we hypothesized, modern/contemporary art was…

A key lever for improving instructional quality centers on providing teachers with professional development (PD) opportunities customized to their instructional needs. To examine whether teacher evaluation reforms led such PD opportunities, we explored the extent to which teachers received PD based on their instructional profiles. To do so, we…

The importance of mathematics in early grades has been well established. Two variables that are associated with mathematics achievement are student-teacher relationships (STR) and student type (students identified with a disability and students not identified with a disability). The current study investigated the interaction between perceived STR…

Coaches develop and use strategies to gain access to teachers' classrooms to support teacher learning and instructional improvement. These strategies respond to the specific conditions in which coaches work, including organizational structures and interpersonal factors that can either facilitate or impede access. In this interview study of 28…

Mathematical flexibility is thought to be a critical component of mathematical proficiency, and the term "mathematical flexibility" has been used by teachers, researchers, and policy makers for more than 2 decades. Although there seems to be consensus on the importance of mathematical flexibility as a construct, the way it is defined and…

Boys and girls sit together in most classrooms, but do they interact? Based on 40-year-old evidence, coeducational classes may not be coeducational but instead segregated by gender, which may undermine student success. Our goal is to answer this question in today's classrooms. We used longitudinal data to assess gender segregation in 26 classes in…

Young students at risk for reading difficulties are likely to have long-term reading difficulties if they are not provided with evidence-based, supplemental instruction. This pilot study evaluated the feasibility of a Tier 2 reading intervention ("Reading RULES! Kindergarten;" RRK) and its promise to improve outcomes for kindergarten…

Parent-teacher relationships are germane to child outcomes and are especially important when children experience social-behavioral difficulties. We used dyadic methods to assess levels and congruence in parent-teacher relationship joining (affective quality) and communication-to-other (communication behaviors). The study also examined whether…

Elementary school principals play a key role in leading school personnel to provide prekindergartners and kindergartners with the support needed to ensure their short- and long-term school success. Yet, few studies examine how principals conceptualize what it means for children to be ready for school and how principals support students as they…

It is urgent to ensure that science, technology, engineering, and mathematics (STEM) education meets the needs of our nation's increasingly diverse student population. This study examined whether a second-grade science program, Scientific Explorers, supported educational equity in STEM achievement for diverse student populations. Sociodemographic…

Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

Classroom reading instruction is the foundation of Multi-Tiered Systems of Support in Reading (MTSS-R) and the focus of many state reading reforms, initiatives, and policies. The purpose of this study was to evaluate whether comprehensive and coordinated Tier 1 core reading instruction was associated with higher early reading outcomes of students…

Motivation is known to fluctuate, often declining, over time. Research on how motivation changes across school years is ubiquitous, yet little research examines changes in motivation within one school year. In this study, we model how third- through fifth-grade students' mathematics motivation (i.e., expectancies and values) changes over two years…

Early mathematics achievement is a strong predictor of later mathematics achievement, and student competence in fractions and division may be the strongest predictor of success in secondary-level algebra. We used a multisite cluster-randomized trial to estimate the impact of a mathematics teacher professional development (PD) program on student…
