Differentiation hypotheses concern changes in the structural organization of cognitive abilities that depend on the level of general intelligence (ability differentiation) or age (developmental differentiation). Part 1 of this article presents a review of the literature on ability and developmental differentiation effects in children, revealing…

Early fine motor ability is significantly associated with later achievement, even after controlling for typical child-level predictors of school outcomes. Previous longitudinal studies have confirmed this but typically have not included low-income, at-risk populations. Research has distinguished two different aspects of fine motor skills: those…

Although the promise of universal social-emotional learning (SEL) programs enhancing student academic outcomes has captured public attention, there has been limited research regarding such programs' impact on students' state test scores. We used multilevel modeling of follow-up data from a multiyear, multisite cluster-randomized efficacy trial to…

Math facts are foundational for later math skill development, but many students demonstrate difficulties with math facts in early schooling. Drill-based interventions have been shown to effectively target foundational academic skills; however, there is limited research examining drill-based interventions for teaching math facts compared to basic…

Science scores among US fourth-grade students have declined compared to their international counterparts in recent years. Recent results show that teachers are the most impactful influence on student success and accountability. Teacher preparedness and professional development are two key areas that serve as indicators of providing relevant and…

Vocabulary knowledge is one of the most important elements of reading comprehension. Text coverage is the proportion of known words in a given text. We hypothesize that text comprehension increases exponentially with text coverage due to network effects and activation of prior knowledge. In addition, the lexical threshold hypothesis states that…

Preparing students for entry into kindergarten is a key priority within the educational sector. Research has shown that students with lower levels of cognitive and socio-emotional competencies are less prepared for kindergarten entry and consequently perform more poorly on assessments in later grades (Duncan et al., 2007; Ensey Hoever, 2014;…

This study aims to scrutinize the effects of gamified Turkish vocabulary teaching on vocabulary development, and motivation on learning words. A nested mixed-method experimental design (gamification-based vocabulary learning for the experimental group instructor-led vocabulary learning for the control group) and was conducted with 34 fourth-grade…

The National Assessment of Educational Progress (NAEP) is the largest continuing and nationally representative assessment of what students in public and private schools know and can do in various subjects. First administered in 1969, NAEP collects and reports information on student trends and performance and compares the achievement of students in…

The purpose of this study is to develop the students' skills of change and continuity through activities based on the objects in fourth-grade social studies. In alignment with the scope, an action research design was used in which the researcher is also the executor. A criterion sampling was used for recruitment which resulted in 17 fourth-grade…

The purpose of the current research is to determine the effect of changing the English Language Art curriculum on the reading growth of fourth-grade students who attended a public school district located in a suburban community in the Northeastern part of the United States. This ex-post facto study is designed to evaluate the effectiveness of the…

The COVID-19 pandemic disrupted traditional learning in schools with the sudden shift to distance learning. Schools continue to see the effects of this shift but must better understand the academic effects on students. The purpose of this study was to determine the extent of COVID Learning Loss in the mathematics and reading scores of elementary…

A 7-month mathematics proficiency program was conducted in a primary Australian Indigenous community school. This paper focuses on outlining the specific methodologies employed to explore how students' mathematical proficiency changed throughout the implementation of the program in Years 2 to 4 (~ 7 to 9 years old). A mixed methods research design…

With the release of the 2017 National Assessment of Educational Progress (NAEP) and 2016 Progress in International Reading Literacy Study (PIRLS) results, concerns that reading scores of U.S. students have remained flat for the past decade have surfaced again along with suggestions about the source of this problem and how it might be remedied. The…
