Academic research has changed in recent years. It has entered the age of abundant scholarly information. New scientometric data shows impressive increases in both the quantity and quality of information researchers produce. Since 2007 about the same number of publications have become accessible on databases as more than the hundred years prior. At…

The purpose of this study was to examine the effects of gamification used in formal educational settings on student affective and behavioral outcomes. Using systematic procedures to identify and screen the manuscripts across 18 academic databases, we identified 13 studies with behavioral outcomes and 19 studies with affective outcomes employing…

We conducted a meta-analysis on the most commonly used forensic polygraph test, the Comparison Question Test. We captured as many studies as possible by using broad inclusion criteria. Data and potential moderators were coded from 138 datasets. The meta-analytic effect size including inconclusive outcomes was 0.69 [0.66, 0.79]. We found…

Collective intelligence (CI) is said to manifest in a group's domain general mental ability. It can be measured across a battery of group IQ tests and statistically reduced to a latent factor called the "c-factor." Advocates have found the c-factor predicts group performance better than individual IQ. We test this claim by meta-analyzing…

A central principle of programmatic assessment is that the final decision is not a surprise to the learner. To achieve this, assessments must demonstrate predictive and consequential validity, however, to date, research has only focussed on the former. The present study attempts to address this gap by examining the predictive and consequential…

The main aim of achieving with the reliability generalization is to investigate the variability related to the reliability estimates and to try to characterize the sources of this variability. As part of the research, a reliability generalization study was carried out on the basis of Beck Depression Inventory-II to investigate potential factors…

There has recently been a surge of interest in improving the replicability of second language (L2) research. However, less attention is paid to replicability in the context of L2 meta-analyses. I argue that conducting interrater reliability (IRR) analyses is a key step toward improving the replicability of L2 meta-analyses. To that end, I first…

Consistently in achievement goal research, pursuing performance-avoidance goals has been associated with a decrease in achievement. Less is known to what extent this effect depends on the reasons underlying these goals' endorsement. The present research uses a social value approach to assess how do performance-avoidance goals' effects on…

Meta-analytic structural equation modeling (MASEM) refers to fitting structural equation models (SEMs) (such as path models or factor models) to meta-analytic data. Currently, fitting MASEMs may be challenging for researchers that are not accustomed to working with R software and packages. Therefore, we developed webMASEM; a web application for…

Prospective registration of study protocols in clinical trial registries is a useful way to minimize the risk of publication bias in meta-analysis, and several clinical trial registries are available nowadays. However, they are mainly used as a tool for searching studies and information submitted to the registries has not been utilized as…

A "P" value, or the magnitude or direction of results can influence decisions about whether, when, and how research findings are disseminated. Regardless of whether an entire study or a particular study result is unavailable because investigators considered the results to be unfavorable, bias in a meta-analysis may occur when available…

The field of educational technology has a rich history of scholarly research incorporating a wide variety of methods, spanning both qualitative and quantitative paradigms, that has been published in an even wider collection of journals. Because our discipline integrates with other disciplines as a "meta" field, publication data is…

The current meta-analysis quantifies the average effect of worked examples on mathematics performance from elementary grades to postsecondary settings and to assess what moderates this effect. Though thousands of worked examples studies have been conducted to date, a corresponding meta-analysis has yet to be published. Exclusionary coding was…

Understanding rational numbers is critical for secondary mathematics achievement. However, students with mathematics difficulties (MD) struggle with rational number topics, including fractions, decimals, and percentages. The purpose of this systematic review was to describe the instructional foci of rational number interventions, determine the…

Purpose: This study aims to support researchers and practitioners in finding suitable instruments for future research studies and organizational quality assessments. Design/methodology/approach: Employees' success of learning at work is strongly influenced by the quality of the workplace learning environment. In the recent decades growing effort…
