The objective of the current study was to identify an effective learning environment for kindergarten students as they acquire an initial understanding of scientific inquiry activities (SIA) and a simple (idealized) scientific inquiry cycle (SIC). The study aimed to examine (a) the effects of instructional support and (b) the role of similarity…

Through a meta-analysis, this study examines how effective particulate nature of matter (PNM)-based intervention studies are at improving academic performance. Well-known databases (e.g., ERIC, Springer Link, Taylor & Francis, and ScienceDirect) were used to look for the PNM-based intervention studies via specific keyword patterns. Also, a…

Background/Context: Literacy stands as a pivotal life skill, especially as it strengthens education across subjects. The elementary years are crucial for mastering literacy, yet national assessments show a decline in elementary students' reading proficiency, with only 33% of American fourth graders reading at grade level (National Center for…

Classrooms today are more ethnically and linguistically diverse. Unfortunately, students of color demonstrate a history of marginalized educational inequities (Williamson et al., 2007). These marginalized educational inequities impact academic achievement across all content areas especially literacy, math, and science. To improve the academic…

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…

Kindergarten is emphasized as a critical first entry into the education system, as politicians and pundits believe kindergartners' success can lead to later academic achievement. Therefore, a comprehensive understanding of kindergarten school readiness data should consider how it is measured and how that affects learning. Using the Early Childhood…

This study examines the associations between class size, teacher characteristics, and children's academic achievement in mathematics, reading, and science using a recent, large-scale, longitudinal dataset. Individual fixed effects models, which control for observed and unobserved time-invariant student variables, were employed to conduct analysis…

Design-based learning (DBL) offers opportunities to support students' content understanding. Previous DBL studies reported different effect sizes by using the data from one participant group. The goal of this study was to conduct a meta-analysis that would give a comprehensive picture of how DBL is connected to student achievement in different…

Executive functions (EF) are domain-general cognitive skills that predict foundational academic skills such as literacy and numeracy. However, less is known about the relation between EFs and science achievement. The nature of this relation might be explained by the theory of mutualism, which states that development is the result of complex and…

This report summarizes the results of kindergarten through fifth grade students' academic achievement outcomes in mathematics and science following four years of campus-level participation in the Launching Elementary Academic Foundations (LEAF) to STEM program. The LEAF to STEM Program consists of three key components that were adapted for K-5…

This study examines the efficacy, cost, and implementation of an integrated science and literacy curriculum for kindergarten. The study was conducted in a large urban district and included 1,589 students in 71 classrooms in 21 schools. The research includes a multi-site cluster-randomized controlled trial and mixed-methods cost and implementation…

Computational thinking is a contemporary science and engineering practice that has been introduced to the US science classrooms due to its emphasis in the "Next Generation Science Standards" (NGSS). However, including computational thinking into science instruction may be challenging. Therefore, for biological evolution (an essential…

Schools across the United States are seeing an increase in culturally and linguistically diverse students. While there is recognition of the need for culturally and linguistically responsive teaching practices in K-12 settings, many teachers encounter challenges in effectively implementing these practices, particularly in science classrooms. There…

Recent evidence demonstrates that disparities by race/ethnicity and socioeconomic status in science achievement are present in the earliest grades of school. Preschool represents one potential policy solution; however, little research has explored the relationship between preschool attendance and science outcomes. This study examines whether…

The Arkansas Better Chance (ABC) program longitudinal study (2009-2020) reviews the changing circumstances and outcomes of participation in Pre-K services in Arkansas. The "core comparison" of this study is between ABC participants and students who had no known Pre-K participation but have similar household income levels. The results…
