A diversity of approaches for critically appraising qualitative and quantitative evidence exist and emphasize different aspects. These approaches lack clear processes to facilitate rating the overall quality of the evidence for aggregated findings that combine qualitative and quantitative evidence. We draw on a meta-aggregation of implementation…

Checking for possible inconsistency between direct and indirect evidence is an important task in network meta-analysis. Recently, an evidence-splitting (ES) model has been proposed, that allows separating direct and indirect evidence in a network and hence assessing inconsistency. A salient feature of this model is that the variance for…

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…

This paper critically explores how survey and routinely collected data could aid in assessing the generalisability of public health evidence. We propose developing approaches that could be employed in understanding the relevance of public health evidence, and investigate ways of producing meta-analytic estimates tailored to reflect local…

Background: Stratified medicine seeks to identify patients most likely to respond to treatment. Individual participant data (IPD) network meta-analysis (NMA) models have greater power than individual trials to identify treatment-covariate interactions (TCIs). Treatment-covariate interactions contain "within" and "across" trial…

Structural equation models play an important role in the social sciences. Consequently, there is an increasing use of meta-analytic methods to combine evidence from studies that estimate the parameters of structural equation models. Two approaches are used to combine evidence from structural equation models: A direct approach that combines…

Conventional wisdom in education has suggested that students who are classified as learning disabled (LD) will exhibit inordinate difficulties learning a foreign language (FL). Even when not explicitly stated, the notion that those classified as LD have a disability for FL learning is implied. However, while beliefs about this purported disability…

Meta-ethnography and systematic review of qualitative research are needed but also challenged by the link to the evidence movement's models and PISA-traditions for measuring learning effects. For reflections on the perspective for meta-ethnography it means to reconstruct the methodological argument almost divided in a "Before and After…

This paper reviews, analyzes, and reflects upon two important reports released in 2013, both discussing research evidence for the value of dance education or arts education more generally, among school-aged students. One report was created by a large dance education advocacy and support group in the USA, the National Dance Education Organization;…

This paper reviews prior research to assess the effectiveness of Title I in closing the achievement gaps of disadvantaged students vis-à-vis their non-disadvantaged counterparts. A research synthesis approach is adopted to summarize national assessments of Title I conducted between 1966 and 2011. These analyses are supplemented by the authors'…

The role that racial identity plays in the well-being, educational achievement, and life outcomes of Black youth has received tremendous attention from the early post-slavery years right up until today, and remains a surprisingly contested area of study. We call for the examination of why images of Black racial identity as "damaged" and…

The Circle of Security™ interventions are psychosocial treatments intended to increase maternal sensitivity and thus child attachment security in infants and young children. A small number of publications have reported empirical research on outcomes of these treatments. This article reviews the research evidence, plausibility, theoretical…

Children and youth with or at risk for emotional and behavioral disorders (EBDs) present substantial challenges for schools, teachers, parents, and peers. Social skills interventions have been shown to be effective for this population. Meta-analytic reviews of this literature show that about 65% of students with EBD will improve when given social…

Distributed leadership is now widely known and variously enacted in schools and school systems. Distributed leadership implies a fundamental re-conceptualisation of leadership as practice and challenges conventional wisdom about the relationship between formal leadership and organisational performance. There has been much debate, speculation and…

This chapter summarizes a set of research studies that focus on high school course offerings, takings, and effects. Improving high school experiences and having students graduate from high school ready for college are national priorities under President Obama's Race to the Top initiative. Doing so by expanding access to advanced courses dates back…
