To assess the meaningfulness of an intervention effect on students' achievement, researchers may apply empirical benchmarks as standards for comparisons, involving normative expectations for students' academic growth as well as performance gaps between weak and average schools or policy-relevant groups (e.g., male and female students, students…

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…

Meta-analysis is the synthesis of findings from research projects, which enables an estimate of the average or pooled effect across various studies. This study presents findings from the intention to treat analysis for a series of educational evaluations in England using a two-stage meta-analysis with standardised outcome data and individual…

Our purpose is to proffer QuantCrit methodological approaches to interrogate notions of statistical practice by convention. We present two approaches to meta-analysis and mean effect size calculations for student achievement. The first approach is the conventional approach which applies between-group differences to calculate effect sizes…

This systematic review of literature synthesizes research on video-based instruction (VBI) to teach mathematics to students with autism spectrum disorder (ASD). Eleven studies, including gray literature, were included in the synthesis resulting in data analysis of performance from 29 participants. To better align with transparent reporting…

The purpose of this study was to proffer the idea to "gaze" past gender and racial achievement gaps by providing a growth-based assessment of the achievement of Black girls. The study aims to elucidate how alternatives to traditional achievement gap analyses can yield information relevant to addressing classroom challenges. This…

Researchers have increasingly investigated sources of variance in reading comprehension test scores, particularly with students with reading difficulties (RD). The purpose of this meta-analysis was to determine if the achievement gap between students with RD and typically developing (TD) students varies as a function of different reading…

Many most well-known charter schools in the United States use a "No Excuses" approach. We conduct the first meta-analysis of the achievement impacts of No Excuses charter schools, focusing on experimental, lottery-based studies. We estimate that No Excuses charter schools increase student math and literacy achievement by 0.25 and 0.17,…

The authors examined differential effects of interim assessments on minority and low socioeconomic status students' achievement in Grades K-6. They conducted a large-scale cluster randomized experiment in 2009-2010 to evaluate the impact of Indiana's policy initiative introducing interim assessments statewide. The authors used 2-level models to…

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'…

In this article, the authors provide a single group summary using the Mathematics Anxiety Rating Scale (MARS) to characterize and delineate the measurement of mathematics anxiety (MA) reported among Black students. Two research questions are explored: (a) What are the characteristics of studies administering the MARS and its derivatives to…

Building upon the research findings in an earlier ACT Research Report (Westrick, 2016), this study used data from 119,131 students at 26 four-year institutions to make comparisons between STEM majors earning semester GPAs of 3.0 or higher and their STEM peers earning semester GPAs less than 3.0. The results indicate that the higher-performing…

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…

Using date from 120,612 students at 26 four-year institutions, this report provides a description of STEM majors entering four-year postsecondary institutions and those who persist through four years of study. The results indicate that persisting STEM majors enter college with very high levels of pre-college academic achievement as measured by the…

The idea of Matthew effects in reading--the widening achievement gap between good and poor reader--has attracted considerable attention in education research in the past 25 years. Despite the popularity of the topic, however, empirical studies that have analyzed the core assumption of Matthew effects in reading have produced inconsistent results.…
