The U.S. Army is interested in extending the application of intelligent tutoring systems (ITS) beyond cognitive problem spaces and into psychomotor skill domains. In this paper, we present a methodology and validation procedure for creating expert model representations in the domain of rifle marksmanship. GIFT (Generalized Intelligent Framework…

The present article demonstrates a way of programming using an Excel spreadsheet to teach Fourier series expansion in school/colleges without the knowledge of any typical programming language. By using this, a student learns to approximate partial sum of the n terms of Fourier series for some periodic signals such as square wave, saw tooth wave,…

Wollack, Cohen, and Eckerly suggested the "erasure detection index" (EDI) to detect fraudulent erasures for individual examinees. Wollack and Eckerly extended the EDI to detect fraudulent erasures at the group level. The EDI at the group level was found to be slightly conservative. This article suggests two modifications of the EDI for…

Searching for information is critical in many situations. In medicine, for instance, careful choice of a diagnostic test can help narrow down the range of plausible diseases that the patient might have. In a probabilistic framework, test selection is often modeled by assuming that people's goal is to reduce uncertainty about possible states of the…

The literature proposes numerous so-called pseudo-R[superscript 2] measures for evaluating "goodness of fit" in regression models with categorical dependent variables. Unlike ordinary least square-R[superscript 2], log-likelihood-based pseudo-R[superscript 2]s do not represent the proportion of explained variance but rather the…

This paper provides a synthesis of core literature of media multitasking, attention, and learning engagement. The focus, however, is on the ecologically valid assessments examining the depth-biased or breadth-biased attention and learning engagement in the media multitasking environments. We propose novel approaches to assess media multitasking…

Situation awareness is a key construct in human factors and arises from a process of situation assessment (SA). SA comprises the perception of information, its integration with existing knowledge, the search for new information, and the prediction of the future state of the world, including the consequences of planned actions. Causal models…

Context: Athletic therapy students learn emergency skills through a variety of modes, including students portraying injured athletes and cardiopulmonary resuscitation manikins. Although acceptable and satisfactory forms of teaching, these methods are limited in their ability to create realistic physiological symptoms of injury. Objective: To…

Proportional reasoning is the basis for most medication calculation processes and is fundamental for high-quality care and patient safety. We designed a simulated Medication Mathematics (siMMath) environment to support proportional reasoning in transitioning via concreteness fading between two mediators. The first mediator is simulated nursing…

We test empirically the strategic counterpart of the Adaptive Decision Maker hypothesis (Payne, Bettman, & Johnson, 1993), which states that decision makers adapt their attention and decision rules to time pressure in predictable ways. For 29 normal form games, we test whether players adapt to tightening time constraints by reducing their…

Simulation is an experiential instructional method that teachers create to imitate or replicate actual events, problems, procedures, or skills to achieve the desired instructional results. Students experience the situation and apply learned skills and knowledge, think critically, and gather meaning from the practice. Simulation as a teaching…

Meta-analysis is a significant methodological advance that is increasingly important in research synthesis. Fundamental to meta-analysis is the presumption that effect sizes, such as the standardized mean difference (SMD), based on scores from different measures are comparable. It has been argued that population observed score SMDs based on scores…

A number of probabilistic experiments are described to estimate e, p and v2, with results from computer simulations being used to investigate convergence. A number of possible classroom exercises and extensions are presented.

The dimensionality of a set of items is important for scale development. In practice, tools that make use of eigenvalues are often used to assess dimensionality. Parallel analysis is featured here as it is becoming an increasingly popular method for assessing the number of dimensions, and computational tools have recently been made available which…

In Oman, applicants are selected for initial teacher education programs (ITEPs) based mainly on their academic achievements. Applicants' non-cognitive attributes (NCAs) (e.g., resilience and motivation) receive less attention. Situational judgment tests (SJTs) are a type of simulation test that are used in the candidate selection process for…
