Background: Research into digital practices and cultures repeatedly calls attention to the complexity of communication spaces and meaning-making practices. With the blurring of boundaries between online and offline, these entangled practices involve the interweaving of human, material, semiotic, and discursive practices. Purpose: This introductory…

Virtual reality (VR) may be used as an innovative educational tool. However, in order to fully exploit its potential, it is essential to achieve the effect of immersion. To more completely submerge the user in a virtual environment, it is necessary to ensure that the user's actions are directly translated into the image generated by the…

The measurement error in principal components extracted from a set of fallible measures is discussed and evaluated. It is shown that as long as one or more measures in a given set of observed variables contains error of measurement, so also does any principal component obtained from the set. The error variance in any principal component is shown…

The correlated trait-correlated method (CTCM) model for the analysis of multitrait-multimethod (MTMM) data is known to suffer convergence and admissibility (C&A) problems. We describe a little known and seldom applied reparameterized version of this model (CTCM-R) based on Rindskopf's reparameterization of the simpler confirmatory factor…

A dominant conceptualization of empathy in social work practice and education, provided by Karen Gerdes and Elizabeth Segal, relies heavily on the simulation theory adopted directly from the cognitive neurosciences. The aim was to critically challenge such a view by reporting on some recent empirical findings from the field in which professional…

The Exploding Carts is a popular introductory physics activity in which a one-dimensional explosion is simulated utilizing two dynamics carts that are pushed apart by a spring-loaded plunger released from one of the carts. Traditional treatments of the Exploding Carts usually involve multiple trials where the mass of one or both of the carts is…

Time and space represent two key aspects of episodic memories, forming the spatiotemporal context of events in a sequence. Little is known, however, about how temporal information, such as the duration and the order of particular events, are encoded into memory, and if it matters whether the memory representation is based on recollection or…

There is room for improvement in the amount of active learning that takes place during physiology laboratory exercises. This paper describes a protocol designed to examine the human dive response, with the goal of creating an integrative laboratory experienced focused around improving active learning. The objectives of this laboratory exercise…

This article describes the incorporation of a refugee simulation into an upper-division sociology course on globalisation at a liberal arts institution in the United States. The simulation is designed to inform students of the refugee process in the United States by inviting participants to immerse themselves in refugee experiences by adopting…

In the absence of tools for intelligent tutoring systems for soaring flight simulation training, this study evaluated a framework foundation to measure pilot performance, affect, and physiological response to training in real-time. Volunteers were asked to perform a series of flight tasks selected from Federal Aviation Administration Practical…

The purpose of this study was to determine if using a multistage approach for the empirical selection of anchor items would lead to more accurate DIF detection rates than the anchor selection methods proposed by Kopf, Zeileis, & Strobl (2015b). A simulation study was conducted in which the sample size, percentage of DIF, and balance of DIF…

In standard item response theory (IRT) applications, the latent variable is typically assumed to be normally distributed. If the normality assumption is violated, the item parameter estimates can become biased. Summed score likelihood based statistics may be useful for testing latent variable distribution fit. We develop Satorra-Bentler type…

As computer-based visualization techniques are becoming more important across the landscape of astronomy education, this pre-test/post-test study using the Size, Scale, and Structure Concept Inventory (S3CI) looked at the impact of using a hybrid combination of hands-on and computer-based activities on the learning of five semesters of non-science…

This study aims to determine the effect of the use of learning media Virtual Reality Laboratory (VR-Lab) on the conceptual understanding of Senior high school students on the concept of electrolytes and non-electrolytes. The learning media used were developed using models adapted from the ADDIE model, while the type of research as a whole uses…

This study was conducted in order to analyze the relation between analytical thinking skill and scientific argumentation in physics learning. The study was conducted with the interactive CK 12 simulation about optics. The sample of the study consists of 28 randomly selected students in Yogyakarta, Indonesia. The data was collected using pre and…
