Evidence-based decision-making is predicated on the ability of users to find and comprehend results from systematic review. Evidence producers have an obligation to support evidence users in this process. The Agency for Healthcare Research and Quality (AHRQ) Evidence-based Practice Center (EPC) program--a producer of rigorous and comprehensive…

As more various types of computer-assisted language learning (CALL) programs have been incorporated into language classrooms over the recent decades, it has become more important to uncover whether, to what extent, and under which moderator variables CALL can be yield more effective outcomes than traditional language instruction. The issue of…

Public health remains acutely affected by the historical legacy and ongoing processes of colonization. Although scholars have advocated for decolonization of public health systems, the principles and processes of decolonization have not been explicitly elaborated nor applied broadly within the field. To map these concepts, we conducted a scoping…

Appropriate assessment practices are recognized as a critical part of the learning process and represent a key component of quality physical education. Recent shifts in school reform efforts toward more accountability in the United States and an emerging emphasis on student-centered approaches challenge historical approaches to assessment.…

Multimedia pedagogical agents are on-screen characters that allow users to navigate or learn in multimedia environments. Several agents' characteristics may moderate their instructional effectiveness, including appearance, gender, nonverbal communication, motion, and voice. Here, we conducted a meta-analysis to test hypotheses from diverse…

This study conducted two meta-analyses to synthesize the association between children's language skills and two broad-band dimensions of psychopathology: internalizing and externalizing. Pooled estimates across 139 samples (externalizing k = 105; internalizing k = 90) and 147,305 participants (age range: 2-17 years old; mean % males: 53.75; mean %…

This meta-analysis examines the inconsistent findings across experimental studies that compared children's learning outcomes with digital and paper books. We quantitatively reviewed 39 studies reported in 30 articles (n = 1,812 children) and compared children's story comprehension and vocabulary learning in relation to medium (reading on paper…

There is debate over the effectiveness of using touch-screen tablet technology on overall student learning gains. This article provides a meta-analysis of studies that used tablets for the delivery of math interventions, programs, or apps to increase student math achievement. A total of 20 group design studies with 2,805 participants were included…

This article reviews research on the achievement outcomes of elementary mathematics programs; 87 rigorous experimental studies evaluated 66 programs in grades K-5. Programs were organized in six categories. Particularly positive outcomes were found for tutoring programs (effect size [ES] = +0.20, k = 22). Positive outcomes were also seen in…

The field of evidence synthesis is growing rapidly, with a corresponding increase in the number of software tools and workflows to support the construction of systematic reviews, systematic maps, and meta-analyses. Despite much progress, however, a number of problems remain, including slow integration of new statistical or methodological…

Background: Network meta-analysis (NMA) is a powerful analysis method used to identify the best treatments for a condition and is used extensively by health care decision makers. Although software routines exist for conducting NMA, they require considerable statistical programming expertise to use, which limits the number of researchers able to…

If IPD is available for some or all trials in a network meta-analysis (NMA), then incorporating this IPD into an NMA is routinely considered to be preferable. However, the situation often arises where a researcher has IPD for trials concerning a particular treatment (eg, from a sponsor) but none for other trials. Therefore, one can reweight the…

Research synthesis, eg, by meta-analysis, is more and more considered in the area of high-dimensional data from molecular research such as gene and protein expression data, especially because most studies and experiments are performed with very small sample sizes. In contrast to most clinical and epidemiological trials, raw data are often…

Multilevel meta-analysis is an innovative synthesis technique used for the quantitative integration of effect size estimates across participants and across studies. The quantitative summary allows for objective, evidence-based, and informed decisions in research, practice, and policy. Based on previous methodological work, the technique results in…

This study reviews the European evidence on the impact of professional development (PD) of pre-school educators on child outcomes. A meta-analysis investigates how PD of pre-school educators in formal pre-school centers in Europe affects child outcomes. The European studies are quite recent and limited in numbers, and our results show a…
