Many school-age pupils are undecided about their future vocation. This often stems from a lack of occupational information or lack of vocationally related experience. The goal of this study was to develop and evaluate an intervention focused on the possibility of changing vocational interests through the simulation of vocational activities. The…

In the logistic regression (LR) procedure for differential item functioning (DIF), the parameters of LR have often been estimated using maximum likelihood (ML) estimation. However, ML estimation suffers from the finite-sample bias. Furthermore, ML estimation for LR can be substantially biased in the presence of rare event data. The bias of ML…

New items are often evaluated prior to their operational use to obtain item response theory (IRT) item parameter estimates for quality control purposes. Fixed parameter calibration is one linking method that is widely used to estimate parameters for new items and place them on the desired scale. This article provides detailed descriptions of two…

The purpose of this research was to establish a case for the use of serious simulation games as a tool to enhance the learning of sales leadership skills. The study provides taxonomy around serious simulation games as a specific modality at the intersection of serious games and simulation games, which have a focus toward education. A literature…

This article asks the question: is the "Last Banana" game fair? Engaging in this exploration provides students with the mathematical power to answer the question and the mathematical opportunity to explore important statistical ideas. Students engage in simulations to calculate experimental probabilities and confirm those results by…

Conducting valid and reliable empirical research in the prevention sciences is an inherently difficult and challenging task. Chief among these is the need to obtain numerical scores of underlying theoretical constructs for use in subsequent analysis. This challenge is further exacerbated by the increasingly common need to consider multiple…

Multifinality, equifinality, and fanning are important developmental concepts that emphasize understanding interindividual variability in trajectories over time. However, each concept implies that there are points in a developmental window where interindividual variability is more limited. We illustrate the multifinality concept under…

This study formalizes and compares two major hypotheses in speakers' choices of referring expressions: the topicality model that chooses a form based on the topicality of the referent, and the rational model that chooses a form based on the informativity of the form and its speech cost. Simulations suggest that both the topicality of the referent…

A key consideration when giving any computerized adaptive test (CAT) is how much adaptation is present when the test is used in practice. This study introduces a new framework to measure the amount of adaptation of Rasch-based CATs based on looking at the differences between the selected item locations (Rasch item difficulty parameters) of the…

Scholars have developed original pedagogical approaches to impart the knowledge and skills required for professional life in the area of peace and development. Experience-based learning, simulations, games, and role-plays have been used with positive results. Yet most efforts tend to overly simplify and narrow down the learning experience in…

What is the impact of active learning techniques on student excitement, interest, and self-efficacy in a course? An American Foreign Policy and National Security course was designed around the utilization of a number of active learning techniques, including simulations, a debate, and counterfactual analysis. Students in the course were surveyed…

Contributions: A concept-map-based remedial learning system is presented to enhance students' grasp of the learning concepts of the IEEE floating-point standard and microprocessor without interlocked pipeline stages (MIPSs) encoding according to their understanding of these learning concepts. Background: Concept maps have been used to represent…

In the COVID-19 pandemic, concerns exist that ventilator triage policies may lead to discrimination against people with disabilities. This study evaluates whether preclinical medical students demonstrate bias towards people with disabilities during an educational ventilator-allocation exercise. Written student responses to a triage simulation…

World politics simulations are gaining popularity and becoming mainstream. With advanced technological tools, experimental learning brings together students from afar increasing the multicultural nature of meetings and practical learning. Progress in running simulations and pedagogical goal fulfillment still require the removal of accessibility…

The Beer-Lambert law is a core spectroscopic relationship widely used across the undergraduate chemistry curriculum and beyond. The derivation of this model is a common topic for upper-level chemistry courses. But, due to its abstract nature, this derivation can often seem like a mathematical exercise detached from the molecular origins of…
