A biology teacher has developed a rare and troubling neurologic disorder. He hears of an experimental treatment that has produced impressive results. The treatment involves surgically ablating selective parts of the brain at close proximity to the brainstem. There is a risk that, during the procedure, vital parts of the brain could be…

Multisensory peripersonal space develops in a maturational process that is thought to be influenced by early sensory experience. We investigated the role of vision in the effective development of audiotactile interactions in peripersonal space. Early blind (EB), late blind (LB) and sighted control (SC) participants were asked to lateralize…

Probability theory has long been taken as the self-evident norm against which to evaluate inductive reasoning, and classical demonstrations of violations of this norm include the conjunction error and base-rate neglect. Many of these phenomena require multiplicative probability integration, whereas people seem more inclined to linear additive…

The authors describe a collection of dynamic interactive simulations for teaching and learning most of the important ideas and techniques of introductory statistics and probability. The modules cover such topics as randomness, simulations of probability experiments such as coin flipping, dice rolling and general binomial experiments, a simulation…

We add to the small literature on private school supply by exploring exits of K-12 private schools. We find that the closure of private schools is not an infrequent event and use national survey data from the National Center for Education Statistics to study closures of private schools. We assume that the probability of an exit is a function of…

This is the fifth in a series of articles describing an attrition prediction and intervention project at the University of South Florida (USF) in Tampa. The project was originally presented in the 83(2) issue (Miller 2007). The statistical model for predicting attrition was described in the 83(3) issue (Miller and Herreid 2008). The methods and…

Individuals with cognitive and developmental disabilities have a high probability of visual impairment. This study revealed the effects of deficits in the appropriate diagnosis of vision and medical treatment, as well as the lack of necessary refraction correction and support, specifically for adults with intellectual and developmental…

Objectives: To determine the prevalence of intimate partner violence (defined as any physical violence during the last 12 months or previously) among mothers who maltreat their children, and to examine whether mothers' experiences of intimate partner violence (IPV) are associated with repeated reports (rereports) of children to Child Protective…

University of Chicago School Mathematics Project (UCSMP) Algebra is a one-year course covering three primary topics: (1) linear and quadratic expressions, sentences, and functions; (2) exponential expressions and functions; and (3) linear systems. Topics from geometry, probability, and statistics are integrated with the appropriate algebra.…

This paper provides a history of ETS's role in developing assessment instruments and psychometric procedures for measuring change in large-scale national assessments funded by the Longitudinal Studies branch of the National Center for Education Statistics. It documents the innovations developed during more than 30 years of working with…

In an effort to improve academic performance for students receiving special education services, a large urban school district in Tennessee has implemented Integrated Service Delivery Model. The purpose of this study was to compare the performance of students receiving instruction in self-contained classrooms to the performance of students…

Child abuse is an important determinant of future violence perpetration and victimization. Past research examining linkages between child abuse and adult intimate partner violence (IPV) has predominantly focused on married individuals and not considered adolescent dating violence. In the present study, data from three waves of the National…

The purpose of this study was to assess the association between acculturation and functional health using multiple proxies of acculturation to examine explanatory pathways to clarify disparate health findings. A population-based cross-sectional, multistage probability sample from the Hispanic Established Populations for the Epidemiologic Studies…

The valuation of academic achievements in students with severe language impairment is problematic if they also have difficulties in sustaining attention and in praxic skills. In severe autism all of these difficulties may occur together. Multiple-choice tests offer the advantage that simple praxic skills are required, allowing the tasks to be…

The purpose of this study is to determine whether educators believe mathematics should be taught to liberal arts students, what topics are taught in liberal arts mathematics courses, and what the motivation is for teaching such topics. The study consists of two parts, a review of the opinions of educators regarding liberal arts mathematics, and a…
