Purpose: The aim of this article is to summarize recent published and unpublished research from our 2 laboratories on improving speech understanding in complex listening environments by listeners fit with cochlear implants (CIs). Method: CI listeners were tested in 2 listening environments. One was a simulation of a restaurant with multiple,…

In this article we present a general approach not relying on item response theory models (non-IRT) to detect differential item functioning (DIF) in dichotomous items with presence of guessing. The proposed nonlinear regression (NLR) procedure for DIF detection is an extension of method based on logistic regression. As a non-IRT approach, NLR can…

Context: Clinical education is a foundational component of healthcare education by which students acquire, practice, and demonstrate competency in clinical proficiencies through classroom, laboratory, and clinical experiences. Currently, the most common practice of clinical education in athletic training is clinical integration. Objective: The…

Virtual teams face unique communication and collaboration challenges that impact climate development and performance. First, virtual teams rely on technology mediated communication which can constrain communication. Second, team members lack skill for adapting process to the virtual setting. A collaboration process structure was designed to…

Detecting Differential Item Functioning (DIF) is an early step and very critical to investigate any possible bias between groups (e.g., males vs. females). Many early DIF studies only focused on two-group comparison. However, there are many cases where more than two groups exist: Cross-cultural studies are administered in many countries and any…

Longitudinal data analysis assumes that scales meet the assumption of longitudinal measurement invariance (i.e., that scales function equivalently across measurement occasions). This simulation study examines the impact of violations to the assumption of longitudinal measurement invariance on growth models and whether modeling the invariance…

The common practice for testing measurement invariance is to constrain parameters to be equal over groups, and then evaluate the model-data fit to reject or fail to reject the restrictive model. Posterior predictive checking (PPC) provides an alternative approach to evaluating model-data discrepancy. This paper explores the utility of PPC in…

A conceptual distinction is drawn between indicators, which serve to define latent variables, and outcomes, which do not. However, commonly used frequentist and Bayesian estimation procedures do not honor this distinction. They allow the outcomes to influence the latent variables and the measurement model parameters for the indicators, rendering…

Pre-laboratory practices and online pre-laboratory resources have been implemented in laboratory courses through various instructional approaches. This study seeks to elicit information about how online multimedia resources are embraced and used in the course system and which factors might affect the adoption of the resources in this context. This…

The purpose of this study is to investigate the effect of augmented reality and mobile application supported instruction on students' academic achievement, attitude towards astronomy, anxiety and motivation towards learning science in the "Solar System and Beyond/Earth and Universe" units in seventh grade Science lesson. In the study,…

Clinical-reasoning (CR) provides a framework for higher-order critical thinking that fosters a nurse's ability to assess, process and remedy clinical encounters and is considered essential for the provision of quality healthcare. This study aimed to determine whether student nurses regard the inclusion of video-simulation with critical-reflection…

In recent times, there has been growing disinterest by students in STEM disciplines (science, technology, engineering, and mathematics). This trend is especially acute in those students who do not take STEM content during their secondary or high school education. This disinterest might be conditioned by negative emotions towards science developed…

Virtual reality (VR) may be useful for situating school-based vocational education in work-life by simulating a work situation such that learners viewing this VR work situation are located inside it. The reason for this assumption is that VR can fully spatially include its viewer. Research on the utility of viewer-including VR work situations for…

The aim of this study is to reveal perceptions of pre-service teachers about 'LEGO robotic instructional practices,' 'augmented reality' and 'flipped classroom' concepts through metaphors. The study is descriptive research that was conducted as a survey model. The study group consists of 37 pre-service teachers studying the undergraduate programme…

We present a systematic review of the literature on the use of multiuser virtual environments (MUVE) on the development of pragmatic competence in second language (L2) learners. Specifically, we reviewed studies examining the potential of L2 pragmatic development through synthetic immersive virtual environment (SIE) and massively multiplayer…
