A new app, freely available for Windows computers, has been developed to simulate tuning of an inductively coupled plasma mass spectrometer, on the basis of optimization data collected using a sector-field instrument. The app allows students to adjust parameters, including the torch position, gas flows, radio-frequency power, and guard-electrode…

On an enactivist conception of cognition, the unit of explanation is not just the brain, not just the body, and not just the environment, but the body--brain--environment understood as a dynamically coupled structure or gestalt. On this view, referencing Viktor von Weizsäcker's metaphor of the gestalt circle (Gestaltkreis), the brain is not in the…

In 2008, articles by Bell and Schroeder provided an initial platform from which to develop a coherent definition of the term 'virtual worlds'. Yet over the past ten years, there has been little development of the term. Instead there is confusion in the literature, with the introduction of new terms which are at times used to classify the type of…

Rounding is a necessary step in many mathematical processes. We are taught early in our education about significant figures and how to properly round a number. So when we are given a data set and asked to find a regression line, we are inclined to offer the line with rounded coefficients to reflect our model. However, the effects are not as…

Scientific disciplines including mathematics, physics, and chemistry tend to adopt online resources, including websites and web applications, to demonstrate physical experiments and simulate scientific phenomena that are hard to observe and investigate in real world. The present study examined the existing collections of the websites and web…

The goal of the present study was to test the hypothesis that, when children respond to peer provocation assertively, their physiology at that moment will be marked by high levels of respiratory sinus arrhythmia (RSA). Participants were 35 European American (66%), African American (27%), Latino American (3%), and mixed race/ethnicity (3%) children…

In recent years, it can be said that the use of new virtual reality related technologies increased swiftly. Especially virtual reality headsets have become an important device in virtual reality and augmented reality applications. As a consequence of these developments, researchers started to investigate the use of virtual reality headsets in many…

In this paper we present two simulations designed with GeoGebra that illustrate dynamically a key concept in Vector Calculus: line integrals of vector fields, along with other associated mathematical properties and applications. Students are not required to know the GeoGebra environment: a user-friendly interface with buttons, functionalities and…

Early exposure to radiological cross-section images during introductory anatomy and dissection courses increases students' understanding of both anatomy and radiology. Novel technologies such as augmented reality (AR) offer unique advantages for an interactive and hands-on integration with the student at the center of the learning experience. In…

To be safe and effective practitioners and learners, medical professionals must be able to accurately assess their own performance to know when they need additional help. This study explored the metacognitive judgments of 157 first-year medical students; in particular, the study examined students' self-assessments or calibration as they engaged in…

Although virtual and augmented reality (VR and AR) techniques have been used extensively in specialized laboratories, only recently did they become affordable, reaching wider consumer markets. With increased availability, it is timely to examine the roles that VR and AR may play in teaching structural biology and in experiencing complex data sets…

Background: Achieving science literacy requires learning disciplinary knowledge, science practices, and development of sophisticated epistemological beliefs about the nature of science and science knowledge. Although sophisticated epistemological beliefs about science are important for attaining science literacy, students' beliefs are difficult to…

Virtual reality has the potential to revolutionize education because it immerses students in their learning, blocking out visual and auditory distractions and letting learners focus intensely on a structured learning experience. The authors describe how using virtual reality headsets helped 5th graders at Gavin Cochran Elementary School in…

Incorporating virtual reality or augmented reality into classroom instruction and activities not only engages students, it provides learning experiences otherwise unavailable, such as virtually walking on the moon or building a 360-degree animation of a Revolutionary War battle. The author gives examples of ways AR and VR can be used in…

The use of business simulation games plays a crucial role in teaching and learning even though it has been used for 60 years since the modern business simulation games started in 1955. Even previous studies have demonstrated the effectiveness of business simulation games used in teaching and learning; however, the major concerns that need to be…
