This paper describes a renal physiology review activity that can be completed during one class session. The activity is a tactile simulation in which colored beads represent various components of the blood, glomerular filtrate, tubular fluid, and interstitial fluid. Students simulate major functions of the nephron by moving beads between…

The traditional Elo rating system (ERS), widely used as a student model in adaptive learning systems, assumes unidimensionality (i.e., all items measure a single ability or skill), limiting its ability to handle multidimensional data common in educational contexts. In response, several multidimensional extensions of the Elo rating system have been…

Objective: Extended reality (XR) has emerged as an innovative educational modality that offers the potential for the creation of more interactive and engaging forms of patient education experiences and products. The purpose of this article is to describe the field of XR technologies and review its potential through a critical lens as well as its…

This paper presents a novel approach for mitigating wormhole attacks on wireless networks using propagation delay timing. The wormhole attack is a persistent security threat that threatens the integrity of network communications, potentially leading to data theft or other malicious activities. While various methods exist for combating wormhole…

Immersive technologies are assumed to have many benefits for learning due to their potential positive impact on optimizing learners' cognitive load and fostering intrinsic motivation. However, despite promising results, the findings regarding the actual impact on learning remain inconclusive, raising questions about the determinants of efficacy.…

Regression discontinuity (RD) designs are increasingly used for causal evaluations. However, the literature contains little guidance for conducting a moderation analysis within an RDD context. The current article focuses on moderation with a single binary variable. A simulation study compares: (1) different bandwidth selectors and (2) local…

Due to the rise of virtual reality and the--at least now--hypothetical construct of the Metaverse, learning processes are increasingly transferred to immersive virtual learning environments. While the literature provides few design guidelines, most papers miss an application and evaluation description of the design and development processes. As a…

This study aims to suggest a generalized class of estimators for population proportion under simple random sampling, which uses auxiliary attributes. The bias and MSEs are considered derived to the first degree approximation. The validity of the suggested and existing estimators is assessed via an empirical investigation. The performance of…

Algorithmic bias is a pressing concern in educational data mining (EDM), as it risks amplifying inequities in learning outcomes. The Area Between ROC Curves (ABROCA) metric is frequently used to measure discrepancies in model performance across demographic groups to quantify overall model fairness. However, its skewed distribution--especially when…

Practice makes perfect…this saying is a popular cliché, but it has validity when referencing the abundance of practice necessary to learn and master a new technique or skill. Like playing a game, honing a skill, or using a new technique, teaching requires practice to learn and improve. Working with preservice STEM teachers (PSTs), my goal was to…

Simulated treatment comparison (STC) is an established method for performing population adjustment for the indirect comparison of two treatments, where individual patient data (IPD) are available for one trial but only aggregate level information is available for the other. The most commonly used method is what we call 'standard STC'. Here we fit…

Conventional random-effects models in meta-analysis rely on large sample approximations instead of exact small sample results. While random-effects methods produce efficient estimates and confidence intervals for the summary effect have correct coverage when the number of studies is sufficiently large, we demonstrate that conventional methods…

This work aims to examine the identities communicated prior to and during a role-playing game (RPG) for individuals with acquired brain injury (ABI). Appraisal, an analysis tool of Systemic Functional Linguistics (SFL), that allows one to examine the interpersonal metafunction, was applied to interview and RPG group treatment conversations. This…

Background: The importance of spatial abilities for individuals' success in science, technology, engineering, and mathematics (STEM) domains has been well established. Researchers have also emphasized the need to train engineering students in spatial ability. Although virtual reality (VR) offers prospects for training spatial abilities, research…

Computer-based simulation is utilised across various educational fields, employing diverse technologies to facilitate practical understanding of content and the acquisition of skills that can help close the gap between theory and practice. The possibility of providing scenarios that resemble on-the-job tasks, enables instructors to both train and…
