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…

"Jigsaw" is a peer learning procedure derived from social interdependence theory, which suggests that individuals positively linked by a common goal can benefit from positive and promotive social interactions (Aronson & Patnoe, 2011). Although jigsaw has often been presented as an efficient way to promote learning, empirical research…

This meta-analysis study synthesized the intervention effects of Check-in/Check-out (CICO), the most common Tier 2 behavior intervention used in schools. Systematic review procedures were employed to examine six CICO studies that were evaluated using a group research design and that involved 146 students. Studies were coded to examine their…

This meta-analysis determined game-based learning's (GBL) overall effect on students' computational thinking (CT) and tested for moderators, using 28 effect sizes from 24 studies of 2,134 participants. The random effects model results showed that GBL had a significant positive overall effect on students' CT (g = 0.677, 95% confidence interval…

This meta-analysis examined the ecological and population validity of intervention research for students with low mathematics achievement (SWLMA). Forty-four studies published between 2005 and 2019 that met the inclusionary criterion were included in this analysis. Our findings suggest, to improve the external validity and generalizability of…

Most students with reading difficulties struggle to read words. We examined intervention effects for students with "significant" word reading difficulties (SWRD; standard score of 80 on at least one pretest measure of word reading), which includes individuals with or at risk for dyslexia. We investigated: (a) What are the effects of…

This Campbell systematic review examines the effects of targeted school-based interventions on standardised tests in reading and maths. The review analyses evidence from 71 studies, 52 of which are randomised controlled trials. School-based interventions targeting students with, or at risk of, academic difficulties in Grades 7-12 have on average…

This meta-analysis synthesized research on math performance outcomes for English learners (EL) as a function of language-focused (math vocabulary) interventions. We included group and single-subject design studies with children from kindergarten to 8th grade (3,766 students for group, 30 for single-subject). Group studies yielded a mean Hedges' g…

Peer bullying in schools is a significant public health problem that contributes to poor health and wellbeing outcomes for those who bully or are bullied. Meta-analyses of the efficacy of secondary school bullying prevention interventions have typically found no effects or an increase in student bullying. Consequently, few secondary school studies…

The incidence of violence in dating relationships has a significant impact on young people, including decreased mental and physical health. This review is the first to provide a quantitative synthesis of empirical evaluations of school-based programs implemented in middle and high schools that sought to prevent or reduce incidents of dating…

Bullying is a pervasive problem that impacts children and youth in schools involved as perpetrators, victims, and bystanders. This paper synthesizes findings from the empirical literature, including meta-analyses, to examine the evidence for bullying prevention and intervention approaches with attention to developmental levels (preschool,…

Background/Context: Despite the surge in efficacy studies, a recent meta-analysis indicates that the relative effectiveness of any two math interventions is largely unknown (Nelson & McMaster, 2019). Additionally, policy makers rarely choose educational programs based on an assessment of costs and cost-effectiveness (Hollands et al., 2016;…

The ability to design and interpret controlled experiments is an important scientific process skill and a common objective of science standards. Numerous intervention studies have investigated how the control-of-variables-strategy (CVS) can be introduced to students. However, a meta-analysis of 72 intervention studies found that the opportunity to…

Teachers and paraprofessionals need effective training to improve their implementation of interventions for students with disabilities. Reviews of the single-case design literature have identified some features associated with effective training for these educators, but the group-design literature has received little attention. This meta-analysis…

Socioeconomic status is a major predictor of educational achievement. This systematic review and meta-analysis seeks to identify effective academic interventions for elementary and middle school students with low socioeconomic status. Included studies have used a treatment-control group design, were performed in OECD and EU countries, and measured…
