Purpose: The purpose of this paper is to improve the understanding of psychological factors that influence inquiry-based leadership. This study investigates how affective attitude, experienced social pressure, and self-efficacy relate to aspects of inquiry-based school leadership. A school leader's inquiry habit of mind, data literacy, and the…

This article reports a systematic review and meta-analysis of studies that use regression discontinuity to examine the effects of placement into developmental education. Results suggest that placement into developmental education is associated with effects that are negative, statistically significant, and substantively large for three outcomes:…

This meta-synthesis investigates the conditions that support teacher innovation in schools. Twenty-seven articles that report on studies using a combination of qualitative and quantitative methodology were selected for this analysis. The articles were analyzed using Hargreaves's and Fullan's concept of "professional capital" as a…

This paper serves two purposes. First, it statistically compares learning outcomes of face-to-face, online and blended learning instruction. Then it looks at the instructional practices that are associated with effective blended and online learning. A meta-analysis of 30 studies, with 3,687 participants, resulted in 36 effect sizes. The contrasts…

Understanding mathematics is an essential part of everyday life and can range from simple tasks such as using basic math skills to more complex tasks. Success in mathematics is a requirement for success in today's modern world. A gap in developing mathematical skills can create complications and interfere with job opportunities. Another basic…

The importance of direct explicit instruction in secondary schools has been shown to improve student learning outcomes across the curriculum. The question then becomes one of whether adapting direct explicit instruction in post-secondary institutions would have the same impact on student grades. Graham and Perin (2007) identified eleven elements…

The current study meta-analyzed single-case design (SCD) and group research regarding incremental rehearsal (IR). We used phi to meta-analyze data from 19 IR studies. Data from the SCD studies resulted in a nonoverlap of all pairs (NAP) score of 98.9% (95% CI = 97.6-100%), which resulted in a weighted phi of 0.77 (95% CI = 0.69-0.83). The group…

This article offers three contributions for conducting meta-analytic reviews in education research. First, we review publication bias and the challenges it presents for meta-analytic researchers. Second, we review the most recent and optimal techniques for evaluating the presence and influence of publication bias in meta-analyses. We then…

An individual diagnostic accuracy study rarely provides enough information to make conclusive recommendations about the accuracy of a diagnostic test; particularly when the study is small. Meta-analysis methods provide a way of combining information from multiple studies, reducing uncertainty in the result and hopefully providing substantial…

Statistical inference is problematic in the common situation in meta-analysis where the random effects model is fitted to just a handful of studies. In particular, the asymptotic theory of maximum likelihood provides a poor approximation, and Bayesian methods are sensitive to the prior specification. Hence, less efficient, but easily computed and…

In this paper we theorize a framework for discussing quality assurance of globalized models of education used internationally. The philosophical assumption that homogeneity of perspectives achieves objectivity in practice is argued against using the examples of (a) Brain drain, and (b) Profit over quality. We present a coherent real world scenario…

Computer games can be considered complex learning environments in which players require instructional support to engage in cognitive processes such as selecting and actively organizing/integrating new information. We used meta-analytical techniques to test if instructional support enhances learning in game-based learning (k = 107, N[subscript adj]…

A latent variable modeling approach is outlined that can be used for meta-analysis of reliability coefficients of multicomponent measuring instruments. Important limitations of efforts to combine composite reliability findings across multiple studies are initially pointed out. A reliability synthesis procedure is discussed that is based on…

Fourteen leadership effect studies that used indirect-effect models were quantitatively analysed to explore the most promising mediating variables. The results indicate that total effect sizes based on indirect-effect studies appear to be low, quite comparable to the results of some meta-analyses of direct-effect studies. As the earlier…

The purpose of this study was to explore the use of robust variance estimation for combining commonly specified multiple regression models and for combining sample-dependent focal slope estimates from diversely specified models. The proposed estimator obviates traditionally required information about the covariance structure of the dependent…
