Statistics is taught at every level of education, yet teachers often have to assume their students have no knowledge of statistics and start from scratch each time they set out to teach statistics. The motivation for this experimental study comes from interest in exploring educational applications of augmented reality (AR) delivered via mobile…

In the first half of the twentieth century, notions such as linguistic structures and students' linguistic capacity were the traditional elements of any language teaching. These notions are yielding their place to the functional use of language and how language is being shaped by the different communicative situations. This communicative approach…

This research explores the role of affect in the domain of human wayfinding by asking if increased motivation will alter the performance across various routes of increasing complexity. Participants were asked to perform certain navigation tasks within an indoor Virtual Reality (VR) environment under either motivated and not-motivated instructions.…

The military's need for high-fidelity games and simulations is substantial, as these environments can be valuable for demonstration of essential knowledge, skills, and abilities required in complex tasks. However assessing performance in these settings can be difficult--particularly in non-linear simulations where more than one pathway to success…

The dominant view of technology so far has been that it is a tool to help improve the teaching of traditional subjects--knowledge mostly about the local and physical world. But technology has created a new realm: the virtual world. It may not be physical or tangible, but the virtual world is indisputable and has a significant economy. If one…

Approaches that use a simulated patient case to study and assess diagnostic reasoning usually use the correct diagnosis of the case as a measure of success and as an anchor for other measures. Commonly, the correctness of a diagnosis is determined by the judgment of one or more experts. In this study, the consistency of experts' judgments of the…

The Goal-based Scenario method is a design model for applying simulations to instruction. This portfolio item describes an implementation of Goal-based Scenarios for the teaching of statistics. The application demonstrates how simulations can be contextualized and how they can allow learners to engage in legitimate inquiry in the pursuit of their…

This article describes how simulation and role play can be important learning strategies that will create long-lasting understanding. Simulation involves participating in a very real learning experience that closely resembles an actual setting. These actual settings may be replicated by either employing models or mannequins or in the case of role…

ADCs (analog-to-digital converters), especially Pipeline and Sigma-Delta converters, are designed using complex architectures in order to increase their sampling rate and/or resolution. Consequently, the learning of ADC devices also encompasses complex concepts such as multistage synchronization, latency, oversampling, modulation, noise shaping,…

The dual-stage two-phase (DSTP) model is introduced as a formal and general model of selective attention that includes both an early and a late stage of stimulus selection. Whereas at the early stage information is selected by perceptual filters whose selectivity is relatively limited, at the late stage stimuli are selected more efficiently on a…

This study investigated the effectiveness of a 20-week Simulated Developmental Horse-Riding Program (SDHRP) by using an innovative exercise equipment (Joba[R]) on the motor proficiency and sensory integrative functions in 60 children with autism (age: 6 years, 5 months to 8 years, 9 months). In the first phase of 20 weeks, 30 children received the…

Standardized parameter estimates are routinely used to summarize the results of multiple regression models of manifest variables and structural equation models of latent variables, because they facilitate interpretation. Although the typical standardization of interaction terms is not appropriate for multiple regression models, straightforward…

This article presents findings from a research project that uses an interactive simulator of an imaginary fishing dispute. Subjects operating the simulator play the role of a state leader, while the computer program controls the behavior of a contending state as well as provides all the environmental data associated with the conflict. The…

As the nation's healthcare education system struggles to keep pace with the demand for its services, educators are seeking creative and innovative solutions to meet the needs of a growing number of students. The integration of medical simulation technology into the community college health science curriculum is a creative solution that can meet…

A number of recent studies have used Meehl's (1995) taxometric method to determine empirically whether one should model assessment-related constructs as categories or dimensions. The taxometric method includes multiple data-analytic procedures designed to check the consistency of results. The goal is to differentiate between strong evidence of…
