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…

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…

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…

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,…

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…

The focus of this paper is on the empirical relationship between item difficulty and item discrimination. Two studies--an empirical investigation and a simulation study--were conducted to examine the association between item difficulty and item discrimination under classical test theory and item response theory (IRT), and the effects of the…

Stellar observation, encompassing the study of star formation, stellar properties, and the governing physical laws, presents a readily accessible topic for many learners; however, many stargazing beginners may find it challenging. By applying the supplemental Gollin effect within animated display and the haptic effect of game-like play with a…

Background: In recent years, immersive virtual reality in education has garnered attention, however, there have been mixed findings on the efficacy of IVR in education. Thus, exploring which strategies are effective in transferring learning from IVR to real-world applications is imperative. Objective: This study aims to investigate the efficacy of…

Background: Flying accuracy is influenced by pilots' affective reactions to task demands. A better understanding of task-related emotions and flying performance is needed to enhance pilot training. Objective: Understand pilot trainees' performance and emotional dynamics (intensity, frequency and variability) based on training phase and difficulty…
