Item difficulty and dimensionality often correlate, implying that unidimensional IRT approximations to multidimensional data (i.e., reference composites) can take a curvilinear form in the multidimensional space. Although this issue has been previously discussed in the context of vertical scaling applications, we illustrate how such a phenomenon…

The purposes of this study were (1) to introduce a virtual dental lab designed to support students' virtual clinical examinations in a dentistry program in South Korea and (2) to determine how dental students' levels of expertise (low, medium, or high) influence their clinical performance in terms of dwell time on each tooth location, total…

Background/purpose: This study aimed to reveal the accuracy of estimation of multiple-choice test items parameters following the models of the item-response theory in measurement. Materials/methods: The researchers depended on the measurement accuracy indicators, which express the absolute difference between the estimated and actual values of the…

This study aims to examine the influence of the role of immersive technology on perceived learning's effectiveness by considering the cognitive load of users when using VR-based learning media. This study involved a total of 91 respondents who had attended virtual reality-based learning training. In this research, SmartPLS was used to test the…

In design education, immersive virtual reality (VR) has grown as a visualization and interaction tool. Nonetheless, little research has been done on how individuals self-perception within VR affects their performance. This self-awareness is carried out using avatars that depict the virtual body through multiple points of view. This article…

This study examined whether answering focused explanative questions during pauses in an immersive virtual reality (IVR) lesson on pipetting procedures could enhance learning. The goal was to take a generative learning activity, known to be effective for declarative knowledge with conventional media, to the context of procedural knowledge with…

In recent years, first responders have faced increasing challenges in their operations, highlighting a growing need for specialized and comprehensive training. In particular, the firefighting incident commanders (ICs) are playing a pivotal role, providing directions to field operators and making critical decisions in emergency situations. Over…

The purpose of this study is to examine the effect of the duration of students' augmented reality (AR) experience on reading comprehension and cognitive load in reading activities carried out with an augmented reality storybook. The participants are 134 secondary school students aged between 11 and 12 attending a school in Antalya. They were…

The adoption of virtual learning environments (VLEs) in education has grown significantly due to their potential to enhance learning. Effective learning in VLEs depends on managing cognitive load and sustaining motivation, particularly for complex tasks like developing teachers' professional vision -- the ability to notice and interpret classroom…

The aim of this study is to find out what the effects of facilitated learning interventions in a simulation game (SG) are and what type of SG renders which type of learning. Therefore, we research the effects of facilitator interventions on learning in an analogue open SG (in which there are as few rules as possible) and an analogue rule based SG…

Introduction: The adoption of simulation technologies in schools of nursing has increased significantly over the last 5 years. Results regarding the use of simulation technology have been positive. The use of simulation technologies has been developed to include complex nursing situations that resemble real clinical settings. Research has…

Background: In multimedia learning environments, pedagogical agents have emerged as an innovative tool to enhance digital instruction, yet optimising their design for maximal learning effectiveness remains underexplored. Objectives: This study aimed to investigate how specific design elements of pedagogical agents, namely appearance and voice…

This study examines the embodied ways in which learners monitor their cognition while learning about exponential functions in an immersive virtual reality (VR) based game, "Pandemic" by Prisms of Reality. Traditionally, metacognitive monitoring has been assessed through behavioural traces and verbalised instances. When learning in VR,…

Cognitive load measurement is a methodological issue of high importance in all learning settings involving a high perceptual richness, such as virtual and augmented reality. As a result of the growing number of cognitive load measurement methods and surveys, it can be difficult to choose the optimal measurement instrument for learning tasks in…

Research methods with roots in complexity science are increasingly popular in social research. However, they are not widespread and have potential to deliver value more fully and consistently to social research and methodology. One reason for this is that methods are often used alone, or only with traditional social research methods. We attempt to…
