Estimation of within-trial interactions in meta-analysis is crucial for reliable assessment of how treatment effects vary across participant subgroups. However, current methods have various limitations. Patients, clinicians and policy-makers need reliable estimates of treatment effects within specific covariate subgroups, on relative and absolute…

Descriptive analyses of socially important or theoretically interesting phenomena and trends are a vital component of research in the behavioral, social, economic, and health sciences. Such analyses yield reliable results when using representative individual participant data (IPD) from studies with complex survey designs, including educational…

In 2016, more than 1.6 million students took the Scholastic Aptitude Test (SAT), a standardized college admissions test (College Board 2016a). Researchers have estimated that 33 percent of students who take the SAT participate in some mode of formal test preparation, such as private tutoring or classes, to prepare for the exam (Buchmann, Condron…

The field of educational leadership has yet to develop a coherent knowledge base that reflects the global diversity of policies and practices. This disconnect -- for example between Asian and Western research, presents a major challenge, curtailing authentic knowledge production and transfer. Accordingly, a major objective for the field is the…

Serious games have become increasingly available to educators. Empirical studies and meta-analyses have examined their impact on learning achievement. However, natural sciences could have a special relation to serious games by their systematic use of quantitative and predictive models that can generate microworlds and simulations. Since no known…

In response to the comment by Vuoksimaa and Kaprio (2010) on our previous article on sex differences in left-handedness (Papadatou-Pastou, Martin, Munafo, and Jones, 2008), we carried out an additional meta-analysis to explore whether the widely observed tendency for rates of left-handedness to be greater among male than female individuals is also…

Each year, the Interagency Autism Coordinating Committee (IACC) releases its annual list of scientific advances that represent significant progress in the field. The 20 studies selected have given new insight into the underlying biology of autism spectrum disorder (ASD) and potential risk factors, tested approaches for improving early screening…

Social-psychological research conducted over the past 15 years provides compelling evidence that pervasive psychological threats are present in common academic environments--especially threats that originate in negative intellectual stereotypes--and that these threats undermine the real-world academic performance of non-Asian ethnic minority…

We previously reported a meta-analysis of explicit memory studies in populations with intellectual disability (ID). The current study discusses the educational implications of this meta-analysis. The main factors at the core of these implications can be divided into two categories: those related to task characteristics (e.g., depth of processing,…

This author became intrigued by the idea that her generation, who had grown up reaping the benefits of second-wave feminism, might differ from previous generations in their attitudes toward women. What was unclear was how this period of progress might have combined with feminist backlash in affecting subsequent generations' responses to typical…

The author comments on the article "The Primacy of Cognition in Schizophrenia," by R. W. Heinrichs and states that to the pursuit of schizophrenic/normal differences, there is no end. Heinrichs used meta-analyses to argue persuasively for the primacy of cognition for this role. His conclusion not only elicited agreement from both researchers and…

Meta-analysis is a set of procedures used to quantify, integrate, and analyze the findings of a large number of research studies. The article describes the new statistical techniques used and provides an example of their application to data regarding gender differences in throwing velocity of children and adolescents.

Describes a meta-analysis that indicated a slight student preference for a traditional educational format over a distance education format in higher education, and little difference in satisfaction levels, even when considering presence and type of interaction. Discusses meta-analysis as a method for synthesizing literature. (Contains 53…

This paper presents cross-section estimates of gross hourly wage premia on tertiary education. They are based on a unified framework for 21 OECD countries from the 1990s to the early 2000s and use international household surveys to maximise international comparability. The results of the "augmented" Mincerian wage equations point to an…

We now stand at an interesting intersection in the perennial debate about the merits of homework, write Marzano and Pickering. Arguments against homework are becoming louder and more popular; at the same time, research is providing growing evidence that homework can be useful when employed effectively. After reviewing three recent books that have…
