Purpose: The purpose of this paper is to examine what factors affect student achievement in reading and mathematics. The research questions addressed the perceptions of school principals and background characteristics related to student achievement in Korea and the USA with respect to differences among students in low, middle and high quantiles.…

Many studies of school achievement find a significant association between reading and arithmetic achievement. The magnitude of the association varies widely across the studies, but the sources of this variation have not been identified. The purpose of this paper is to examine the magnitude and determinants of the relation between arithmetic and…

Despite a great increase in the numbers of students enrolling in higher education, specifically at community colleges, the successful completion rates for these students has remained static since the 1970s. When reviewing strategies to increase student retention and successful completion, the Student Success Course (SSC) has emerged as a promising…

The present study examined whether and how socioeconomic status (SES) predicts school achievement in science, technology, engineering, and math (STEM) using structural equation modeling and data from the National Institute of Child Health and Human Development Study of Child Care and Youth Development. The present inquiry addresses gaps in…

Teachers need more clarity about effective teaching practices as they strive to help their low-achieving students understand mathematics. Our study describes the instructional practices used by two teachers who, by value-added metrics, would be considered "highly effective teachers" in classrooms with a majority of students who were…

This study aimed to explore the cross-lagged association of achievements in mathematics and languages. While the effect of language on achievements in mathematics is well-documented, few studies have examined the reciprocal relationships among mathematics, the Chinese language and the English language in the same study. This study conducted a…

This paper examines how international, large-scale skills assessments (ILSAs) engage with the broader societies they seek to serve and improve. It looks particularly at the discursive work that is done by different interest groups and the media through which the findings become part of public conversations and are translated into usable form in…

This study aims to investigate the effectiveness of the Emporium instructional method in a course of college algebra and trigonometry by comparing to the traditional lecture method. The math emporium method is a nontraditional instructional method of learning math that has been implemented at several universities with much success and has been…

In this paper, we describe findings from a three-year evaluation of a well-developed mathematics professional development program that is commercially available on a wide scale. The professional development is designed to improve teachers' mathematical knowledge for teaching and to enable them to elicit more student thinking and reasoning during…

In this investigation, the relationship between bilingual education program type (i.e., dual language programs or exit programs) and English Language Learner reading and mathematics test scores was examined. Data were obtained on English Language Learners who were enrolled in Grades 3, 4, 5, and 6 in Texas public schools for the 2008-2009,…

There is no comprehensive database of U.S. district-level test scores that is comparable across states. We describe and evaluate a method for constructing such a database. First, we estimate linear, reliability-adjusted linking transformations from state test score scales to the scale of the National Assessment of Educational Progress (NAEP). We…

To comply with Section 1111(e) of the Elementary and Secondary Education Act (ESEA) as amended by the Every Student Succeeds Act (ESSA), states are required to submit evidence associated with their assessment systems to the United States Department of Education (ED) for peer review. Thirty-eight states submitted evidence for their assessment…

The District of Columbia Opportunity Scholarship Program (OSP) was created by Congress to provide tuition vouchers to low-income parents who want their child to attend a private school. The Scholarships for Opportunity and Results (SOAR) Act of 2011 also mandated an evaluation of the OSP program. This report examines impacts one year after…
