Purpose: The overall goal of the current study was to determine whether noise type plays a role in perceptual quality ratings. We compared quality ratings using various noise types and signal-to-noise ratio (SNR) ranges using hearing aid simulations to consider the effects of hearing aid processing features. Method: Ten older adults with bilateral…

With advances in technology, researchers and test developers are developing new item types to measure complex skills like problem solving and critical thinking. Analyzing such items is often challenging because of their complicated response patterns, and thus it is important to develop psychometric methods for practitioners and researchers to…

One important issue in Bayesian estimation is the determination of an effective informative prior. In hierarchical Bayes models, the uncertainty of hyperparameters in a prior can be further modeled via their own priors, namely, hyper priors. This study introduces a framework to construct hyper priors for both the mean and the variance…

Courses: Public Relations, Organizational/Crisis Communication, Social Media in Organizations. Objective: The goal for this activity is for students to simulate an organizational response to an environmental/health crisis impacting their business operations. By working through various components of a crisis event, students apply theoretical…

Synthesizing findings about the indirect (mediated) effect plays an important role in determining the mechanism through which variables affect one another. This simulation study compared six methods for synthesizing indirect effects: correlation-based MASEM, parameter-based MASEM, marginal likelihood synthesis, an adjustment to marginal likelihood…

This contribution presents and discusses the methodology and results of a panel study analyzing the effects of a simulation on students' learning outcomes. The focus is on how sustainable knowledge acquisition can be enhanced through participation in simulation as well as on presenting and discussing one way this learning can be analyzed. The…

Modeling is an important element of discovery and design processes because it can help individuals to comprehend and facilitate solutions to problems, mediate among mental and external representations, and off-load cognitive demands. However, engaging in model generation, comprehension, and transformation requires the orchestration of domain…

One of the most understudied health disparity populations in the United States is the Deaf community, a sociolinguistic minority group of more than 500,000 individuals who communicate via American Sign Language. Research on Deaf health disparities is lacking due to inaccessible recruitment, sampling, and data collection procedures, as well as the…

The purpose of this research was to explore how effective the bottom-up approach to producing and shaping educational legislation is in Ukraine and to identify what observed changes take place in students if the bottom-up approach is simulated in the classroom. Qualitative instruments and observational data were used to yield the data. Those were…

This article illustrates the benefits of off the shelf simulation software to increase learning for students in the classroom. Furthermore, the use of a computer game presents a unique opportunity for increased understanding of transportation fundamentals in a fun environment. Another benefit is that the use of the simulation helps Millennial…

With the adoption of the 2015 Educational Policy and Accreditation Standards, the Council on Social Work Education accepted simulation as a means for students to accumulate field practice hours. However, little research exists addressing the use of simulation for social work student development. To effectively utilize simulation to develop social…

Meta-analyses are often used to estimate the relative average values of a quantitative outcome in two groups (eg, control and experimental groups). However, they may also examine the relative variability (variance) of those groups. For such comparisons, two relatively new effect size statistics, the log-transformed "variability ratio"…

Two paradigms inform responses to active shooting situations: a traditional lockdown approach where individuals find cover in a classroom and lock the door, and a multi-option approach where individuals evacuate the area, create barricades, and, in last resort situations, actively resist the gunman. While a majority of schools conduct active…

The performance of statistical methods is often evaluated by means of simulation studies. In case of network meta-analysis of binary data, however, simulations are not currently available for many practically relevant settings. We perform a simulation study for sparse networks of trials under between-trial heterogeneity and including multi-arm…

Research has explored the use of simulations for education and training, and attention is turning to how they might support learning in school subjects such as mathematics and science. However, existing studies have mostly concentrated on older students, and if simulations help build knowledge useful for solving problems "within" the…
