The study examines students' skills at kindergarten entry and gains in skills across the kindergarten through first-grade period (pre-COVID-19) for predicting literacy, language, math, inhibitory control, and social-adjustment outcomes in the spring of fourth grade, after schools reopened. In a large US school district, longitudinal data were…

Longitudinal models of individual growth typically emphasize between-person predictors of change but ignore how growth may vary "within" persons because each person contributes only one point at each time to the model. In contrast, modeling growth with multi-item assessments allows evaluation of how relative item performance may shift…

Longitudinal models typically emphasize between-person predictors of change but ignore how growth varies "within" persons because each person contributes only one data point at each time. In contrast, modeling growth with multi-item assessments allows evaluation of how relative item performance may shift over time. While traditionally…

TOOLBOX is a school-based social and emotional learning (SEL) program to teach and reinforce 12 tools (e.g., Breathing Tool, Courage Tool) for healthy youth development. Although TOOLBOX has been broadly adopted, it remains largely untested. This quasi-experimental study aims to examine the relationship between TOOLBOX implementation and the…

Background: Recent studies have found the effects of improvements in teachers' content knowledge (CK) on enacted pedagogical content knowledge (PCK) and student learning outcomes. However, there is little research exploring the relationship between PCK and student learning in an individual fundamental motor skill-based elementary physical…

The quality of parental support is recognized as a crucial factor in the early stages of a student's development, and particularly in instrumental music education. At the start of 2020, the outbreak of a global pandemic crisis posed new and unprecedented challenges to education, forcing families to stay at home to prevent contagion. This…

The aim of this longitudinal research is to examine the development process of scientific and consistent knowledge structures of first, second, and third-grade students in middle school within the concepts of melting and dissolution according to conceptual change theories at the end of the education and training processes carried out in…

Even though small group instruction is a research-based intervention and has many benefits, researchers have shown that many students are reading below grade level and struggle with mastering reading skills, and this may be due to the ineffectiveness of small-group reading instruction. The problem that was addressed in this study was teachers'…

This study reports achievement and growth from kindergarten to 4th grade for three groups of English Learners (ELs): (a) ever-ELs; (b) ELs consistently eligible for service; and (c) EL and Special Education dually-identified students. All three EL groups had lower test scores than never-ELs throughout K-4. In math, ELs grew more than never-ELs…

The current study aimed to understand the perceptions of kindergarten and primary (Grades 1 and 2) educators in Ontario, Canada, regarding their students' developmental and academic skills and their own mental health during the 2021 to 2022 school year. Participants comprised 402 Ontario educators who completed an online survey. Educators…

This study examined the impact of a commonly adopted elementary universal social-emotional learning program, Second Step, on student social-emotional and academic outcomes following 2 years of implementation. The cluster-randomized wait-list control trial included 61 schools, 321 teachers, and 8,941 early elementary students across 2 states, with…

Dynamic Measurement Modeling (DMM) is a recently-developed measurement framework for gauging developing constructs (e.g., learning capacity) that conventional single-timepoint tests cannot assess. The current project developed a person-specific DMM Trajectory Deviance Index (TDI) that captures the aberrance of an individual's growth from the…

Literacy development involves not only the cultivation of new practices but also of new identities. Drawing on theories of stance and positioning, this study examines the identity negotiations of one first-grade student with his teacher across a semester. Through close analysis of the stance bids and negotiations within a series of writing…

The linguistic, mathematical, social-emotional, and cognitive precursor competencies are important predictors of learning success already at kindergarten age. A systematic analysis of the state of research on the actual interrelationships of the focused precursor competencies brings together results of a meta-analysis. The literature search…

Math achievement is an important predictor of progression to later science, technology, engineering, and math (STEM) education and careers. However, attitudinal factors also play a role, and interventions attempting to improve math attitudes may be important for increasing the number of STEM-aspiring students. To design effective interventions, it…
