An application for visualizing the dynamic properties of an equimolar binary mixture of isotropic reactive particles is presented. By introducing a user selectable choice for the activation energy, the application is useful to demonstrate qualitatively that the reaction rate depends on the above choice and on temperature. The application is based…

A virtual reality (VR) session was introduced to an advanced inorganic chemistry class, a class available to junior and senior undergraduate students at the University of California, Los Angeles. The VR session helped the students to learn complicated aspects of metal coordination chemistry and molecular orbitals via an immersive three-dimensional…

Three intrastate universities developed a corporate social responsibility (CSR) simulation in an upper-division, undergraduate online markets and stakeholders class. The simulation engaged students in serving as business leaders in a community devastated by an earthquake. The students selected business leadership roles within the simulation based…

Hypothesis generation is an important but difficult process for students. This study investigated the effects of providing students with support for hypothesis generation, with regard to the testability and complexity of the generated hypotheses, the quality of the subsequent inquiry learning processes and knowledge acquisition. Fifty-two…

We present the design of a citizen science system that uses machine learning to guide the presentation of image classification tasks to newcomers to help them more quickly learn how to do the task while still contributing to the work of the project. A Bayesian model for tracking volunteer learning for training with tasks with uncertain outcomes is…

The development of ICT has led to the use of simulation and visualisation (S&V) in various domains as a useful virtual interactive tool. Although there are many discussions and related studies on the relevancy of S&V in current applications, the tools and methods proposed do not sufficiently meet the needs of the different and dynamic…

Traditional psychometric guidelines suggest that at least several hundred respondents are needed to obtain accurate parameter estimates under the Rasch model. However, recent research indicates that Rasch equating results in accurate parameter estimates with sample sizes as small as 25. Item parameter drift under the Rasch model has been…

Mark Weiser coined the term Ubiquitous Computing (UbiComp) describing a future in which everyday life-objects would have embedded computers providing services anytime and anywhere. This paradigm is theme recurrent in many graduate courses of Computer Science around the world. To better understand the challenge of teaching Ubiquitous Computing…

In recent years, virtual reality (VR) technology has been widely available for psychological research in spatial cognition. Studies focusing on the training and testing of navigational and wayfinding skills are increasingly using virtual environment (VE) paradigms, which offer significant benefits in experimental control, ecological validity, and…

Introduction: Space utilization is important for academic librarians to understand in order to meet the needs of library users who range from students to faculty. This paper reports on a literature review to investigate why a space utilization study is conducted and what methodologies should be employed. The literature review of space utilization…

Purpose: Graduate employability represents a fundamental outcome of higher education. The purpose of this paper is to explore and compare students' perceptions of their employability through their experience of a simulated or real-life project. The context of the project is a capstone course, implemented in an Australian university, which was…

This article explores the various ways that teachers and learners can navigate different learning worlds with the support of digital tools. Increasingly, teaching and learning takes place in spaces beyond the classroom, whether physical or virtual. Place, navigation and movement have all been recognised as important concepts in approaches to…

We present noncompetitive adsorption as "particles in a box with one sticky wall." We start with a general model that can be modeled as a simple ordinary differential equation (ODE). To verify the ODE students run a computer simulation. The ODE's solution imperfectly fits the simulation's data. This leads to the diffusion partial…

In this article we make recommendations based on our qualitative inquiry into one elementary teacher's iterative processes of designing and implementing technology-enhanced instruction using virtual reality (VR). The use of VR has gained more attention from educational researchers and practitioners but evidence-based demonstrations of how teachers…

The main objective of this paper is to provide an explanation on a conceptual level of how the Mirascope and the occurring image formation work. The physics behind a Mirascope--a well-known device consisting of two concave mirrors--is very complex. In literature, only either high level or very simplified and deficient explanations can be found.…
