Purpose: This study determines the relationship between a medical school applicant's rural background and the likelihood of rural practice using different definitions of rural background. Methods: Cohort study of 599 physicians who entered the University of Virginia School of Medicine in 1990-1995 and graduated in 1994-1999. The…

Recent literature has focused on how school size influences both costs and outcomes (for example, test scores and educational attainment). It also emphasizes how school size may change the nature of educationally relevant social interactions among students, teachers, and administrators. However, there appears to be little corresponding evidence on…

In this paper an attempt is made to highlight some issues of interpretation of statistical concepts and interpretation of results as taught in undergraduate Business statistics courses. The use of modern technology in the class room is shown to have increased the efficiency and the ease of learning and teaching in statistics. The importance of…

A set of design patterns for digital item types has been developed in response to challenges identified in various projects by teachers in higher education. The goal of the projects in question was to design and develop formative and summative tests, and to develop interactive learning material in the form of quizzes. The subject domains involved…

Mathematics achievement is important in its own right, and is increasingly recognized as crucial to the nation's economy [National Mathematics Panel, 2006. "National Mathematics Advisory Panel: Strengthening Math Education Through Research." Accessed September 29, 2006 from http://www.ed.gov/about/bdscomm/list/mathpanel/factsheet.html.; National…

The paper discusses the interaction between intuitive biases of probabilistic thinking and mathematical knowledge. It would appear that students may answer numerical problems correctly but falter on simple descriptive solutions. Students appear to relinquish formal knowledge for simpler heuristics when attempting to describe the outcome of an…

Because youth gangs tend to cluster in disadvantaged neighborhoods, adolescents living in such neighborhoods are more likely to encounter opportunities to join youth gangs. However, in the face of these opportunities, not all adolescents respond in the same manner. Those with preexisting psychopathic tendencies might be especially likely to join.…

Investigating the role of preferences in causing persistent patterns of racial residential segregation in the United States has a long history. In this paper, we bring a new perspective--and new data from the 2004 Detroit Area Study--to the question of how best to characterize black and white preferences toward living in neighborhoods with people…

This paper presents findings from a study of the experiences and outcomes of older and younger community college students. We developed a discrete-time hazard model using longitudinal transcript data on a cohort of first-time community college students in Florida to compare the impact of enrollment pathways (such as remediation) and enrollment…

While the association between teenagers' work and academic performance continues to be debated in studies of adolescent employment, many researchers have found that "intensive" involvement in paid work increases the risk of high school dropout. It is still unclear, however, whether this relationship is spurious owing to preexisting differences in…

This report examines the relationship between various characteristics of students with disabilities and the probability that they would participate in the NAEP assessments, given the current methods of accommodation adopted by their state. The report describes the methodological approach which calculates for each state an expected inclusion rate…

The effectiveness of cooperative learning arrangements is often attributed to the fact that the learners are not only "passive" recipients but also "active" explainers. To test this assumption experimentally explaining and listening were compared with respect to motivation and learning results. Forty first-year college…

Methodological issues of using a class of neural networks called Mixture Density Networks (MDN) for discriminant analysis are discussed. MDN models have the advantage of having a rigorous probabilistic interpretation, and they have proven to be a viable alternative as a classification procedure in discrete domains. Both classification and…

This book contains 40 lessons in problem solving divided into five chapters. Chapter 1 contains several lessons in which solutions are derived through investigation of numerical patterns. Chapter 2 contains lessons in which problem-solving situations are presented in a graphical context. It also includes two lessons in which students construct…

Recently considerable attention has been given in the online information retrieval literature to techniques for producing a weighted output of documents in response to a request. One approach tries to maintain the form of and relationships among requests as they appear in current Boolean logic-based systems, while extending it to permit a weighted…
