There exists a variety of interval estimators for the overall treatment effect in a random-effects meta-analysis. A recent literature review summarizing existing methods suggested that in most situations, the Hartung-Knapp/Sidik-Jonkman (HKSJ) method was preferable. However, a quantitative comparison of those methods in a common simulation study…

This systematic review and meta-analysis explores the impact of motivational reading interventions on the reading achievement and reading motivation of school-age students. Results of preliminary searches for--and inspection of--the existing meta-analytic literature suggest that while there exist published meta-analyses on motivational reading…

Selective publication and reporting in individual papers compromise the scientific record, but are meta-analyses as compromised as their constituent studies? We systematically sampled 63 meta-analyses (each comprising at least 40 studies) in "PLoS One," top medical journals, top psychology journals, and Metalab, an online, open-data…

This study explores the performance of classical methods for detecting publication bias--namely, Egger's regression test, Funnel Plot test, Begg's Rank Correlation and Trim and Fill method--in meta-analysis of studies that report multiple effects. Publication bias, outcome reporting bias, and a combination of these were generated. Egger's…

STEM education is an educational approach whose popularity has increased in recent years. Although numerous efforts have been made to make STEM education more effective, educators face great difficulties in finding appropriate teaching methods and strategies. Within this framework, the aim of this research is to examine the results of studies that…

The aim of this study is to analyze the effect of drama method on academic achievement and attitude in preschool and primary school in terms of meta-analysis and meta-synthesis in Turkish sample. In this study, a methodological approach was used that combines meta-analysis of quantitative data with qualitative data to present the broadest view of…

Recently, Picho-Kiroga (2021) published a meta-analysis on the effect of stereotype threat on females. Their conclusion was that the average effect size for stereotype threat studies was d = .28, but that effects are overstated because the majority of studies on stereotype threat in females include methodological characteristics that inflate the…

The present study examines the existing published research about the effectiveness of learner-generated highlighting and instructor-provided highlighting on learning from text. A meta-analysis was conducted of scientifically rigorous experiments comparing the learning outcomes (i.e., performance on memory and/or comprehension tests) of students…

Background: Many researchers have explored the impact of various technologies in museums on learning effects. Whether the application of technology in informal museum learning is effective, is the current issue that scholars pay more attention to. Objectives: This study will find the evidence to determine the effects of technology use on museum…

Anxiety is the most common mental health problem that occurs with Autism Spectrum Disorder (ASD), and due to creating a more inclusive learning environment, children with ASD are placed in general education classrooms. Thus, addressing anxiety problems for children with ASD in school settings become critically important. This systematic review and…

Background: There have been several studies that involved technology-based self-monitoring procedures to increase on-task behavior. Although there are continued advancements in technology application such as functions that are embedded in the application (e.g., reinforcement, feedback), the appropriate use of technology is required to be…

This systematic review and meta-analysis is the first to evaluate the effects of group-based social skills training (SST) on parent-report social responsiveness in adults with autism spectrum disorder (ASD). A total of 18 studies were included in the narrative review and among them five randomized-controlled trials (n = 145) were included in the…

This meta-analysis examines the effects of game-based learning (GBL), compared with traditional instructional methods, on the science achievement of students, ranging from primary school to university. Results from the 41 primary studies of 6256 participants showed heterogeneity among effect sizes. The random effects model results showed a…

Since 1975, researchers have conducted interventions to improve the word-problem performance of elementary school students facing mathematics difficulties. The current study reports a meta-analysis of 52 studies that examined the effect of these interventions. We estimated multivariate, random-effects models (REM) with robust variance estimation…

Research indicating many study results do not replicate has raised questions about the credibility of science and prompted concerns about a potential reproducibility crisis. Moreover, most published research is not freely accessible, which limits the potential impact of science. Open science, which aims to make the research process more open and…
