Noting the dependency of healthcare education on practice-based learning, Michael Begg, Rachel Ellaway, David Dewhurst, and Hamish Macleod suggest that creating a virtual clinical setting for students to interact with virtual patients can begin to address educational demands for clinical experience. They argue that virtual patient simulations that…

Colleges and universities head into virtual worlds, and student learning and psychology are changed forever. For the past few years, Creighton University, a Jesuit institution of about 6,700 students has hosted GameFest (www2.creighton.edu/doit/gamefest), a 12-hour marathon of high-tech, interactive gaming sessions among Creighton students, using…

This article discusses modern stereoscopic displays for geographic education, focusing on a large-format display--the GeoWall. To evaluate the potential of the GeoWall, geography instructors were asked to express their reactions to images viewed on the GeoWall during a focus group experiment. Instructors overwhelmingly supported using the GeoWall,…

Spatial visualization is a fundamental skill in technical graphics and engineering designs. From conventional multiview drawing to modern solid modeling using computer-aided design, visualization skills have always been essential for representing three-dimensional objects and assemblies. Researchers have developed various types of tests to measure…

Objective: There is a high risk of vehicular crashes, traffic citations, and poorer driving performance in adults with ADHD. This pilot study examines the value of a new nonstimulant (atomoxetine) for improving the driving performance of adults with ADHD. Method: Atomoxetine (1.2 mg/kg daily for 3 weeks) and a placebo are studied on 18 adults with…

An $11 million executive-training course for principals, modeled after best practices used in the corporate, medical, engineering, and military worlds, is starting to gain traction among states. Developed by the National Institute for School Leadership, or NISL, a for-profit company based in Washington, the program is now used widely in…

This article explores the benefits of the Internet to enhance history instruction for all learners. The authors describe a Web-based learning environment, the Virtual History Museum (VHM), that helps teachers create motivating, inquiry-based history units. VHM also allows teachers to build supports for learners with disabilities or other learning…

As computer-mediated communication becomes increasingly prevalent in the workplace, students need to apply effective writing principles to today's technologies. Email, in particular, requires interns and new hires to manage incoming messages, use an appropriate tone, and craft clear, concise messages. In addition, with instant messaging (IM)…

Electronic game technologies can prepare novice learners for future learning of complex concepts. This paper describes the underlying instructional design, learning science, cognitive science, and game theory. A structural, or syntactic mapping (structure mapping), approach to game design can produce a game world relationally isomorphic to a…

The work of R. MacCallum et al. (1992) was extended by examining chance modifications through a Monte Carlo simulation. The stability of post hoc model modifications was examined under varying sample size, model complexity, and severity of misspecification using 2- and 4-factor oblique confirmatory factor analysis (CFA) models with four and eight…

This paper describes a computer model that simulates the way children develop the reasoning skills of transitive inference and the construction of ordered sets. The computer model begins from general operations, such as setting and removing goals, storing and retrieving information, comparing elements to find matches, reading premises, and giving…

This repeated measures factorial design study compared the results of two procedures for identifying multivariate outliers under varying conditions, the Mahalanobis distance and the Andrews-Pregibon statistic. Results were analyzed for the total number of outliers identified and number of false outliers identified. Simulated data were limited to…

Sequential probability ratio testing (PRT), which usually is applied in situations requiring a decision between two simple hypotheses or a single decision point, is extended to include situations involving k decision points and [(k + 1)-choose-2] sets of simultaneous, simple hypotheses, where k>1. The multiple-decision point or…

The rank transformation approach to analysis of variance (ANOVA) as a solution to the Behrens-Fisher problem was examined. Using simulation methodology, four parameters were manipulated for the two-group design: (1) ratio of population variances; (2) distribution form; (3) sample size; and (4) population mean difference. As a general solution to…

The predicted scores produced by regression with (1) single best predictor, (2) two best predictors, (3) all predictors with observed values, and (4) all predictors with or without observed values were compared with variable means as estimates of missing values. The study was conducted in a simulation mode on nx8 data matrices using various levels…
