It is a healthy exercise to debate the merits of using effect-size benchmarks to interpret research findings. However, these debates obscure a more central insight that emerges from empirical distributions of effect-size estimates in the literature: Efforts to improve education often fail to move the needle. I find that 36% of effect sizes from…

This article reviews over 50 years of research on teacher expectations and teacher effectiveness. In addition to describing these research traditions and findings, I tie the research in these evolving fields to the societal issues in play when the research was conducted and connect historical and emerging work. I describe the enormous growth of…

This meta-analysis examines the effects of sorting secondary students into different tracks ("between-school" tracking) or classrooms ("within-school" tracking) on the efficiency and inequality levels of an educational system. Efficiency is related to the overall learning achievement of students, whereas inequality can refer to…

The research on students who do not graduate from high school has traditionally focused on students who drop out before their expected graduation date. This ignores the experiences of "persisters" or "persisting students"--those who remain enrolled in high school on or beyond their expected graduation date, but have yet to earn…

Meta-analysis comprises a powerful tool for synthesising prior research and empirically validating theoretical frameworks. Using this tool and two recent multilevel models of educational effectiveness as guiding frameworks, this paper synthesises the results of 195 studies investigating the association between system-level characteristics and…

This report presents findings from two studies examining accommodations policies and research on alternate assessments based on alternate academic achievement standards (AA-AAAS). This policy analysis and literature review revealed several key insights about accommodations for AA-AAAS, with far-reaching implications for policy, practice, and…

For decades, there have been competing visions of how and where to educate students with disabilities (SWDs) in America's K-12 schools. One conception is that general classrooms can accommodate the learning needs of virtually all children. A second approach calls for multiple placement options. Over the years, the context in which this…

Meta-analyses and international large-scale assessments (ILSA) are key sources for informing educational policy, research, and practice. While many critical research questions could be addressed by drawing evidence from both of these sources, meta-analysts seldom integrate ILSAs, and current integration practices lack methodological guidance. The…

In the context of the equity/widening participation policy landscape in Australia, scholarly exploration of alternative pathways into higher education is becoming increasingly important to inform innovative pedagogies, answer complex questions, and improve outcomes and experiences for students. This article focuses on one alternative pathway,…

This systematic review presents the first synthesis of the scientific literature on estimating school and teacher/class effects on student academic performance using random-effects (RE) models with three or more levels. The review delves into the theoretical framework underpinning the estimation of educational effects, the associated statistical…

Despite upwards of 100,000 gifted students possibly being educated at home, research regarding this population is limited. The literature on gifted homeschooling includes topics such as motivations for homeschooling, modalities of instruction, and student achievement and social-emotional wellness. Recommendations for expanding the literature and…

Gendered patterns of achievement emerged as a critical policy concern for the small island developing states of the Anglophone Caribbean as early as 1986. Although these patterns are mostly variegated, some males do appear to be disadvantaged on key schooling outcomes as evident in the literacy attainment gap for Trinidad and Tobago in PISA 2009…

Access to tertiary education is a challenge for many people from refugee-backgrounds. In Aotearoa New Zealand (NZ), resettled refugees are entitled to access education alongside other New Zealanders, and NZ's resettlement policy material recognises education as a key pillar of resettlement. However, refugee-background students are not recognised…

Early childhood researchers from across the U.S. came together to form the Early Learning Network (ELN) in 2016 with the mission to identify policies and practices that narrow opportunity gaps and help children maintain early learning success. Early Learning Network teams share what they have learned--and what it means for early childhood…

Background: Media play an important role in shaping public perceptions of education policies, yet few studies have explored how research evidence is included in media coverage of education reforms. Purpose: In this study, we investigate how research appears in the public discourse of student achievement in the context of the reauthorization of the…
