The purpose of this review was to conduct a meta-analysis of 25 years of mathematics interventions for students with mathematics difficulty or disability in Grades 4 through 12. A search of the literature yielded 25 studies that met the inclusion criteria. Studies were coded to extract important study information (e.g., participant information,…

In this study, through a meta-analysis of 20 studies, it is aimed to compare the effectiveness of various forms of learning methods including creativity based learning, problem based learning, and differentiated instruction on creativity in terms of the academic achievement of students and to find out other study characteristics, related to the…

The statistical method "meta-analysis" is perhaps unique as a contribution to empirical inquiry of many types because it arose entirely within the practice of education research. In spite of its origins, meta-analysis has found its widest application and most important contributions in the field of medicine. Contrasting the success of…

Calls for universal preschool programs have become commonplace, reinforced by President Obama's call for "high-quality preschool for all" in 2013. Any program that could cost state and federal taxpayers $50 billion per year warrants a closer look at the evidence on its effectiveness. This report reviews the major evaluations of preschool…

This study explores the extent to which differences in research design explain variation in Head Start program impacts. We employ meta-analytic techniques to predict effect sizes for cognitive and achievement outcomes as a function of the type and rigor of research design, quality and type of outcome measure, activity level of control group, and…

This meta-analysis summarizes results from k = 24 studies comparing either Brief Strategic Family Therapy, Functional Family Therapy, Multidimensional Family Therapy, or Multisystemic Therapy to either treatment-as-usual, an alternative therapy, or a control group in the treatment of adolescent substance abuse and delinquency.

Compared to controls, SEL participants demonstrated significantly improved social and emotional skills, attitudes, behavior, and academic performance that…

Using meta-analysis, we reviewed the effectiveness of resident fathering education programs. Our review identified 16 studies with over 200 reported effect sizes. Results revealed a significant overall effect size of d = 0.26, with specific significant outcomes ranging from d = 0.14 to d = 0.61. Studies with father-only reports produced…

Objectives: This article presents a systematic evaluation of the effectiveness of interventions aimed at reducing distress in adult victims of rape and sexual violence. Method: Studies were eligible for the review if the assignment of study participants to experimental or control groups was by random allocation or parallel cohort design. Results:…

This investigation used meta-analytic techniques to evaluate the effectiveness of school-based prevention programming in reducing cannabis use among youth aged 12 to 19. It summarized the results from 15 studies published in peer-reviewed journals since 1999 and identified features that influenced program effectiveness. The results from the set of…

This article presents a method to evaluate pretest effects on posttest scores in the absence of an un-pretested control group using published results of pretesting effects due to Willson and Putnam. Confidence intervals around the expected theoretical gain due to pretesting are computed, and observed gains or differential gains are compared with…

Excitement and controversy have surrounded the effectiveness of Early Intensive Behavioral Intervention (EIBI) for young children with autism. The purpose of this meta-analysis was to investigate the effectiveness of EIBI based on applied behavior analysis in young children with Autism Spectrum Disorders (ASD). There were 11 studies with 344…

For decades, college access programs have aimed to improve college readiness and enrollment rates, particularly for underrepresented populations. Though several published reports have produced comprehensive inventories of college access programs (Gandara, 2001; Perna, 2002; Tierney, Bailey, Constantine, Finkelstein, & Hurd, 2009), no systematic…

A meta-analysis of 16 subjective and objective sleep studies with a sample of 722 children with attention deficit hyperactivity disorder (ADHD) versus a control that numbers 638 shows that the children with ADHD are significantly more impaired in most of the subjective and some of the objective sleep measures than their counterpart.
