A small subset of education studies analyzes school data collected seasonally (separating the summer from the school year). At first, this work was primarily known for documenting learning loss in the summers, but scholars have since recognized that observing how inequality changes between summer and school periods provides leverage for…

IES is the primary research, evaluation, and statistics arm of the U.S. Department of Education. Established through the Education Sciences Reform Act of 2002 (ESRA), the Institute's mission is to expand fundamental knowledge and understanding of education and to provide education leaders and practitioners, parents and students, researchers, and…

This special issue is dedicated to understanding how to best support positive educational outcomes for all students. While reading strategies, course design and methods, testing and assessment, and a variety of other factors are all integral to L2 reading outcomes, policies constructed at the federal, state, district, and school level play an…

Often it is infeasible or unethical to use random assignment in educational settings to study important constructs and questions. Hence, educational research often uses observational data, such as large-scale secondary data sets and state and school district data, and quasi-experimental designs. One method of reducing selection bias in estimations…

Although International Association for the Evaluation of Educational Achievement-pioneered international large-scale assessment (ILSA) of education is now a well-established science, non-practitioners and many users often substantially misunderstand how large-scale assessments are conducted, what questions and challenges they are designed to…

Prototype work can support the creation of data visualizations throughout the research and development process through paper prototypes with sketching, designed prototypes with graphic design tools, and functional prototypes to explore how the implementation will work. One challenging aspect of data visualization work is coordinating the expertise…

Reports of international large-scale assessments tend to evaluate and compare education system performance based on absolute scores. And policymakers refer to high-performing and economically prosperous education systems to enhance their own systemic features. But socioeconomic differences between systems compromise the plausibility of those…

This paper uses public schools data to examine the effects of age on student academic achievement in light of recent trends to delay children's entry into kindergarten. To avoid problems of endogeneity, students' quarters of birth is employed as an instrument for age at entry. In particular, the effects of students' quarters of birth on math and…

Causal inference is central to educational research, where in data analysis the aim is to learn the causal effects of educational treatments on academic achievement, to evaluate educational policies and practice. Compared to a correlational analysis, a causal analysis enables policymakers to make more meaningful statements about the efficacy of…

This study examines trends in American students' growth trajectories in reading and math achievement over the past three decades. Drawing upon multiple sources of national assessment data, cohort analyses provide new evidence on the stability and change of national academic growth curves. The emerging trends imply a tripartite pattern where…

Big-fish-little-pond effect (BFLPE) research has demonstrated that academic self-concept is negatively affected by attending high-ability schools. This article examines data from large, representative samples of 15-year-olds from each Australian state, based on the three Program for International Student Assessment (PISA) databases that focus on…

The present study sought to investigate the influence different or mixed allographic presentations would have on sight word reading achievement of fourth grade pupils. As well it considered whether word identification is based on a process reaction to letter cues or word form cues. (Author/RK)

This paper examines whether teachers in schools serving students from high-poverty backgrounds are as effective as teachers in schools with more advantaged students. The question is important. Teachers are recognized as the most important school factor affecting student achievement, and the achievement gap between disadvantaged students and their…

This article reports a synthesis of intervention studies conducted between 1994 and 2004 with older students (Grades 6-12) with reading difficulties. Interventions addressing decoding, fluency, vocabulary, and comprehension were included if they measured the effects on reading comprehension. Twenty-nine studies were located and synthesized.…

Private schooling in the third world is on the increase and in particular in one of the low-income areas of India, where a data analysis on Hyderabad has been carried out. The University of Newcastle has conducted an initiative research in Hyderabad on the impact on pupils' progress in Reading and Spelling tests. This initiative was called…
