This case study describes how path analysis and causal modeling were used to assess the impact of federal research and development spending on Ph.D production in science and engineering at leading research universities. The nature of existing data, integrated into a single data base from seven surveys, influenced the research methodology. (BS)

Recent federal legislation has dealt directly with medical school class size. This study examines the relationship between increases in entering class size in American medical schools and changes in a variety of educational variables. (LBH)

The National Governors' Association is urging states to develop a standardized cohort graduation rate definition and to develop data systems with quality data that can in turn be used to produce a reliable indicator. This paper is an examination of one state's graduation rate using the cohort method. The statistics generated are compared to a…

Secondary education continues to expand rapidly worldwide. Equally important is its diversification. The present paper contends that the diversification of secondary education, while acknowledged, is not well studied. Despite the widespread expansion of secondary education in different world regions, the information available to researchers--and…

Problems of scale typically arise when comparing test score trends, gaps, and gap trends across different tests. To overcome some of these difficulties, we can express the difference between the observed test performance of two groups with graphs or statistics that are metric-free (i.e., invariant under positive monotonic transformations of the…

A preliminary set of analyses was conducted linking students to courses and courses to teachers based upon data collected by the Louisiana Department of Education's Divisions of Planning, Analysis, and Information Resources and Student Standards and Assessments. An analysis of covariance, a weighted analysis of covariance, and a hierarchical…

The Association for Children of New Jersey (ACNJ) is committed to ensuring that decisions about children's lives are made on sound information and that state leaders and the public are fully informed. It is the public debate that has kept reform moving forward and will be necessary to ensure success. ACNJ believes that it is critically important…

Using data from the 2003 "Baccalaureate and Beyond Longitudinal Study" ("B&B:93/03"), this report provides an overview of the status of 1992-93 college graduates 10 years after graduation. The report presents highlights of these college graduates' lives in 2003 in five areas: (1) education after the bachelor's degree; (2)…

A multi-faceted Rasch measurement (MFRM) approach was used to analyze clinical performance ratings of 24 first-year residents in one surgery residency program in Thailand to investigate three types of rater effects: leniency, rater inconsistency, and restriction of range. Faculty from 14 surgical services rated the clinical performance of…

A multi-faceted Rasch measurement (MFRM) model was used to analyze a clinical skills assessment of 173 fourth-year medical students in a Midwestern medical school to investigate four types of rater errors: leniency, inconsistency, halo, and restriction of range. Each student performed six clinical tasks with six standardized patients (SPs), who…

Opportunities for school choice in the United States have expanded since the 1990s. This report uses data from the National Household Surveys Program (NHES) to present trends that focus on the use of and users of public schools (assigned and chosen), private schools (church-and nonchurch-related), and homeschoolers between 1993 and 2003. The…

This paper examines issues related to the statistical power of impact estimates for experimental evaluations of education programs. The focus is on "group-based" experimental designs, because many studies of education programs involve random assignment at the group level (for example, at the school or classroom level) rather than at the student…

This paper presents a secondary analysis of the National Assessment of Educational Progress (NAEP) dataset. The study explores differences in the NAEP fourth, eighth, and twelfth grade reading scores by students' gender across the years 1992, 1994, 1998, 2000, 2002, and 2003. The study used the NAEP National Public School data. The statistically…
