Numerous studies have been conducted to date on the effectiveness of the flipped classroom. However, the results of studies reporting on the model are generally inconsistent. The aim of this research was to evaluate the results of these primary studies in a comprehensive manner, and to obtain general results to document the effectiveness of…

Teacher absenteeism has high individual and societal costs and triggers a vicious cycle by increasing teacher absenteeism for the remaining teachers. Moreover, teachers' non-attendance disrupts the learning process and affects student motivation and achievement. Teacher absenteeism further exacerbates the increasing teacher shortage observed in…

Using meta-analytic techniques, we examined systematically the evidence linking peer social acceptance to academic achievement. Based on 72 studies that yielded 157 effect sizes, we analyzed relations between social acceptance and academic outcomes (e.g., academic grades, test scores), including the extent to which relations were moderated by sex,…

This study aims to examine the effect of parental involvement on students' academic achievement at pre-school, elementary and secondary levels by using the meta-analysis method with respect to home-based and school-based parental involvement strategies. Data consisted of 55 independent research studies in English published between 2010 and 2019,…

This research synthesis examined the impact of grades, comments, and no performance feedback on academic motivation and achievement in elementary and secondary school. Four meta-analyses were conducted, with two each exploring the impact of (a) grades versus no performance feedback and (b) grades versus comments on academic motivation and…

Since the standards-based education movement began in the early 1990s, mathematics education reformers have developed and evaluated many interventions to support students in mastering more rigorous content. We conducted a systematic review and meta-analysis of U.S. PreK-12 mathematics intervention effects from 1991 to 2017 to study sources of…

This meta-analysis of 28 studies examines the relationship between parental involvement and the academic achievement and school behavior of Latino pre-kindergarten-college-age children. Analyses determined the effect sizes for parental involvement overall and specific categories of involvement. Results indicate a significant relationship between…

The primary purpose of this study was to determine what trends exist in the identification and description of participants with disabilities used in school-based physical education research. A total of 60 research articles published in the "Journal of Teaching in Physical Education" from 2010-2014 which included school-aged individuals…

This meta-analysis reviewed 82 school-based, universal social and emotional learning (SEL) interventions involving 97,406 kindergarten to high school students (M[subscript age] = 11.09 years; mean percent low socioeconomic status = 41.1; mean percent students of color = 45.9). Thirty-eight interventions took place outside the United States.…

This study aims to assess the strength of the effect of gender, if there is any, on the perceptions of teachers on organizational culture in a meta-analysis. 27 studies consisting of Master's theses and PhD dissertations were chosen from the National Thesis/Dissertation Database provided by Turkish Council of Higher Education. The sample consists…

Read aloud is a testing accommodation that has been studied by many researchers, and its use on K-12 assessments continues to be debated because of its potential to change the measured construct or unfairly increase test scores. This study is a summary of quantitative research on the read aloud accommodation. Previous studies contributed…

This meta-analysis synthesizes the literature on interventions for struggling readers in Grades 4 through 12 published between 1980 and 2011. It updates Scammacca et al.'s analysis of studies published between 1980 and 2004. The combined corpus of 82 study-wise effect sizes was meta-analyzed to determine (a) the overall effectiveness of reading…

Magnet schools are one of the largest sectors of choice schools in the United States. In this study, we explored whether there is heterogeneity in magnet school effects on student achievement by examining the effectiveness of 24 recently funded magnet schools in 5 school districts across 4 states. We used a two-step analysis: First, separate…

The purpose of this study was to determine if meta-analysis can be used to enhance efforts to identify evidence-based practices (EBPs). In this study, the quality of included studies acted as the moderating variable. I used the quality indicators for experimental and quasi-experimental research developed by Gersten, Fuchs, Coyne, Greenwood, and…

Clinical trials exploring the effectiveness of counseling and psychotherapy in treatment of depression in school-age youth composed this meta-analysis. Results were synthesized using a random effects model for mean difference and mean gain effect size estimates. No effects of moderating variables were evident. Counseling and psychotherapy are…
