Evaluation professionals can benefit from practice in the same way that lawyers, doctors, and other professionals improve their performance through practice. The case method enables practice through role plays and situational analyses. Cases provide openings for evaluators and program planners to experiment with new norms of communication…

Objective: To compare simulator-based teaching with traditional instruction among clinical medical students. Methods: Randomized controlled trial with written pre-post testing. Third-year medical students (n = 38) received either a myocardial infarction (MI) simulation followed by a reactive airways disease (RAD) lecture, or a RAD simulation…

The 1992 NIH Research Planning Conference on Prosthetic and Orthotic Research for the 21st Century (Childress, 1992) recognized that the field of prosthetics lacks theoretical understanding and empirical studies on learning to control an upper-extremity prosthesis. We have addressed this problem using a novel approach in which persons without…

In this paper, a didactical proposal is presented to introduce the variational methods for solving boundary value problems to engineering students. Starting from a couple of simple models arising in linear elasticity and heat diffusion, the concept of weak solution for these models is motivated and the existence, uniqueness and continuous…

Virtual flight can be very entertaining, and computer-based simulators can also be educational, if organized and used correctly. When Berea College decided to find a flight simulator suited to the school's educational goals, the faculty settled on an ANT-18 Link trainer. This article begins with a discussion of Link trainers' history, and then…

Sportsmanship is a component that is increasingly missing in youth sports. Negative experiences resulting from poor sportsmanship may lead children to limit their participation in sports or drop out all together. Parks, recreation, and tourism professionals may look to systems modeling to help develop programs and policies in the hope of…

A Bayesian approach is developed for analyzing nonlinear structural equation models with nonignorable missing data. The nonignorable missingness mechanism is specified by a logistic regression model. A hybrid algorithm that combines the Gibbs sampler and the Metropolis-Hastings algorithm is used to produce the joint Bayesian estimates of…

An attempt is made to translate the concept of perceived realism from the domain of general media studies to the domain of videogame studies. In order to make such a translation, a thorough knowledge and integration is required of the simulation aspects that distinguish videogames from older media such as film or television. The different meanings…

Alternative approaches to evaluating critical thinking skills are needed, as pencil and paper assessments may not accurately predict simulated or actual clinical performance. To ensure patient safety, it is imperative to determine how to best promote and measure critical thinking skills. Few studies have examined how these skills are related to…

Prior work has proposed different theoretical mechanisms to explain students' course-taking patterns in schools. On the one hand, there are oversocialized accounts that claim that rules, social background factors, and supply-side factors shape observed career patterns. On the other hand, there are undersocialized accounts that claim that the…

Hierarchical educational structures employ a standards-driven decision-making atmosphere that challenges teachers' autonomy. This situation represents a critical issue for teacher educators who must consider how they will teach candidates to respond to these settings. We argue that teacher empowerment represents a moral issue that teacher…

Over the course of instruction, instructors generally collect a great deal of information about each student. Integrating that information intelligently requires models for how a student's proficiency changes over time. Armed with such models, instructors can "filter" the data--more accurately estimate the student's current proficiency…

The basic properties of extensive air showers of particles produced in the interaction of a high-energy primary cosmic ray in the Earth's atmosphere are discussed in the context of educational cosmic ray projects involving undergraduate students and high-school teams. Simulation results produced by an air shower development code were made…

We illustrate a class of multidimensional item response theory models in which the items are allowed to have different discriminating power and the latent traits are represented through a vector having a discrete distribution. We also show how the hypothesis of unidimensionality may be tested against a specific bidimensional alternative by using a…

The author presents five classroom activities that involve students in the settlement at Jamestown. Activity 1 simulates the problems encountered on the "Godspeed," a fifty-two-foot foot boat with fifty-two passengers traveling across the Atlantic in 1607 for three slow months. In Activity 2, students plot their route, ocean currents,…
