Conceptual replications are part and parcel of education science. Methodologically rigorous conceptual replication studies permit researchers to test and strengthen the generalizability of a study's initial findings. The current conceptual replication sought to replicate the efficacy of a small-group, first-grade mathematics intervention with 240…

Toward the goal of more rapid knowledge accumulation via better meta-analyses, this article explores statistical approaches intended to increase the precision and comparability of effect sizes from education research. The featured estimate of the proposed approach is a standardized mean difference effect size whose numerator is a mean difference…

Purpose: The purpose of this study is to investigate the effectiveness of online self-leadership training (OSLT) in promoting leaders' self-leadership skills and recovery experiences. Design/methodology/approach: A non-randomized controlled trial was conducted under two conditions--a standardized seven-week OSLT (N = 43) and a control without any…

Multimedia learning often consists of a sequence of tasks, and research suggests that the sequence itself may influence learning outcomes. This study examines one theory related to task sequencing, known as ego depletion, and its interaction with a well-established instructional design effect, the seductive details effect. To investigate the…

Prior research has shown that social-emotional learning (SEL) interventions offer promise for supporting young children's outcomes, but implementation problems are frequent, especially in low-resource contexts. This study describes the adaptation and efficacy of a new, classroom-based SEL intervention for children aged 3 to 6 years in early…

Background: Compensatory cleft speech disorders can severely impact speech understandability and speech acceptability. Speech intervention is necessary to eliminate these disorders. There is, however, currently no consensus on the most effective speech therapy approach to eliminate the different subtypes of compensatory cleft speech disorders.…

The purpose of the study was to examine the effectiveness of "efitbuddy," a theory-based smartphone application, on young adults' BMI, physical activity, and motivation across a 4-week intervention. Participants were a convenience sample of 312 (mean age = 19.4 ± 2.3 years) college students. A quasi-experimental design with the control…

A vast majority of elementary students struggle with the core, pre-algebraic concept of mathematical equivalence. The Improving Children's Understanding of Equivalence (ICUE) intervention integrates four research-based strategies to improve outcomes for second grade students: (1) introducing the equal sign before arithmetic, (2) non-traditional…

Trials evaluating the same interventions rarely measure or report identical outcomes. This limits the possibility of aggregating effect sizes across studies to generate high-quality evidence through systematic reviews and meta-analyses. To address this problem, core outcome sets (COS) establish agreed sets of outcomes to be used in all future…

The aim of this study was to explore how the Coding as Another Language using ScratchJr (CAL-ScratchJr) curriculum, developed by Boston College's DevTech Research Group utilizing the ScratchJr app, impacted second grade students' computational thinking, coding skills, and reading comprehension. To accomplish this, the research team randomly…

Response shifts can be defined as a change in the way that a respondent interprets and responds to symptom questionnaire items, over and above true changes in their symptoms. Response shifts are liable to occur as a result of psychotherapy and can undermine evaluations of the effectiveness of psychotherapy interventions by making pre- and post-…

Background: Children's participation in cooking activities at home may have positive effects on diet quality. In Japan, schools are the primary site for food education, which includes cooking. Very few studies have assessed the impact of school-based cooking programmes on children's participation in cooking activities at home. Objective: The…

This study's purpose was to investigate effects of 3 intervention approaches for building working memory (WM) and improving word-problem solving (WPS). Children with mathematics difficulties (n = 240; 7.51 years [SD = 0.33]) were randomized to 4 conditions: a control group, general WM training with contiguous math practice, WPS intervention…
