This annotated bibliography represents a first step toward compiling a comprehensive overview of current research on issues related to English language learners (ELLs). It is intended to be a resource for researchers, policymakers, administrators, and educators who are engaged in efforts to bridge the divide between research, policy, and practice…

On July 17, 2008 the U.S. Department of Education's Office of Vocational and Adult Education (OVAE) awarded a contract to the American Institutes for Research (AIR) to assist OVAE in conducting a descriptive study of instructional and programmatic practices that support the transition of English language learners (TELL) from English as a second…

The collision between funding realities and the paramount goal of increasing educational attainment has brought new attention to ways to reduce postsecondary attrition and get more students who enroll in college to complete a degree or credential. Reductions in attrition are both educationally effective and cost effective. Students reach…

Previous research on attrition has focused on the economic consequences of low graduation rates in terms of costs to students and families (from tuition and fees that do not culminate in a credential), lost time, and income and tax losses from low educational attainment in the workforce. However, no systematic attention has been given to another…

One of the primary goals of Early College High Schools is to enroll students who are underrepresented in higher education. This brief report describes the strategies ECHSs have used to recruit students from groups that are traditionally underserved and underrepresented in higher education and addresses the impact of the recruitment and selection…

In 2003, U.S. students' mathematics performance was assessed by the Trends in International Mathematics and Science Study (TIMSS) for students in grades 4 and 8 and by the Program for International Student Assessment (PISA) for students at age 15. Results in the press and later summaries, such as that found in The Condition of Education (NCES,…

This exploratory study compares key features of the Singapore and U.S. mathematics systems in the primary grades, when students need to build a strong mathematics foundation. It identifies major differences between the mathematics frameworks, textbooks, assessments, and teachers in Singapore and the United States. It also presents initial results…

This report is the first in a series of reports on teaching and learning in Foundation-supported schools. This report takes a careful look at instruction and students' academic work. In a subset of reforming schools, it examines whether students are exposed to challenging learning opportunities and whether challenging learning opportunities open…

The question of whether single-sex schooling is preferable to coeducation for some or all students continues to be hotly debated. Much of the debate is philosophical and would be waged even if single-sex schooling were shown to be highly advantageous for one or more subpopulations. However, the actual research evidence, although suggestive that…

This study presents a strategic review of the current quality and effectiveness of more than 40 online professional development (OPD) sites for teachers of mathematics. The evidence gathered about this relatively new form of professional development was compared with evidence on the quality and effectiveness of traditional face-to-face…

What is the cost of providing all New York public school students a full opportunity to meet the Regents Learning Standards? This report presents the results of a fifteen-month project undertaken jointly by American Institutes for Research (AIR) and Management Analysis and Planning, Inc. (MAP) to answer this question. This is a "costing out"…
