The history of vocabulary research has specified a rich and complex construct, resulting in calls for vocabulary research, assessment, and instruction to take into account the complex problem space of vocabulary. At the intersection of vocabulary theory and assessment modeling, this paper suggests a suite of modeling techniques that model the…

To increase opportunities for students to take more advanced math courses in high school, many school districts enroll grade 8 students in Algebra I, a gateway course for advanced math. But students who take Algebra I in grade 8 and skip other math courses, such as grade 8 general math, might miss opportunities to develop the foundational…

This brief summarizes the practices of successful, instructionally engaged leaders and the ways districts develop these leaders. These practices are drawn from "positive outlier" districts in California that have excelled at helping African American, Latino/a, and White students achieve at high levels on assessments of academic standards…

Hispanic students continue to be underrepresented among employees in the fields of science, technology, engineering, and math (STEM) in the United States. Among students who decide to major in a postsecondary STEM field, Hispanic students persist at lower rates than non-Hispanic White students (Higher Education Research Institute, 2010). Concern…

This brief summarizes successful strategies for creating a strong and stable teaching force. These strategies are drawn from "positive outlier" districts in California that have excelled at helping African American, Latino/a, and White students achieve at high levels on assessments of academic standards in English language arts and…

The purpose of this review is to systematically uncover relevant studies in the literature that measure the effects of class size on academic achievement. The review will synthesize the effects in a transparent manner and, where possible, the review will investigate the extent to which the effects differ among different groups of students such as…

This Methodological Brief introduces the reader to the regression discontinuity design (RDD), which is a method that when used correctly can yield estimates of research treatment effects that are equivalent to those obtained through randomized control trials and can therefore be used to infer causality. However, RDD does not require the random…

Standardized admissions tests such as the SAT (originally stood for "Scholastic Aptitude Test") and the ACT measure only a narrow segment of the skills needed to become an active citizen and possibly a leader who makes a positive, meaningful, and enduring difference to the world. The problem with these tests is that they promised, under…

States and school districts are exploring alternatives to state tests for measuring teachers' contributions to student learning. One approach applies statistical value-added methods to alternative student assessments such as commercially available tests and end-of course tests. The evidence suggests that these methods can reliably distinguish…

Many assessment experts believe it is essential to develop faculty-driven assessment tools in order to engage faculty in meaningful assessment that can improve student learning. Tennessee Technological University (TTU) has been involved in an extended effort during the last ten years to develop, refine, and nationally disseminate an instrument to…

The existence of standardized tests drives the school curriculum, marginalizing nontested subjects. In particular, the arts (fine and applied) are all too often the first to be reduced or eliminated in a budget crisis. Even without a budget crisis, their position is precarious in today's "back to basics" environment, and teachers of these subjects…

This report uses administrative data provided by the Los Angeles Unified School District (LAUSD) on kindergarten to third-grade students. The records begin with kindergartners in 2001, first-graders in 2002, second-graders in 2003, and third-graders in 2004 and include all LAUSD students in grades K-3 for 2004 to 2008. Altogether, the raw data…

This chapter summarizes ten selected issues and common problems that arise in most assessment research projects. These include: (1) the uses of grades in assessment; (2) institutional review boards; (3) research design as a compromise; (4) standardized testing; (5) self-reported measures; (6) missing data; (7) weighting data; (8) conditional…

One literature documents a significant, black-white gap in average test scores, while another finds a substantial narrowing of the gap during the 1980's, and stagnation in convergence after. We use two data sources -- the Long Term Trends NAEP and AFQT scores for the universe of applicants to the U.S. military between 1976 and 1991 -- to show: 1)…
