Purpose: This paper aims to contribute to a general understanding of mental practice by investigating the utility of and participant reaction to a virtual reality maintenance training among underground coal mine first responders. Design/Methodology/Approach: Researchers at the National Institute for Occupational Safety and Health's Office of Mine…

Purpose: The purpose of this paper is to describe the ongoing shift in sustainable engineering and the approaches used by universities for engineering students. At the United Nations Earth Summit, in Rio de Janeiro, in 1992, participating nations agreed to work together to achieve the goal of sustainable development. Twenty years on, great…

Purpose: The aim of this article is to investigate the creative knowledge processes which are often invisible in innovation work. Design/methodology/approach: An ethnographic field study was conducted following three multidisciplinary groups; two groups in an Oil and Gas Company, Statoil and one group in a Research Institute. Data collection…

A simple capacitive cell for dielectric constant measurement in liquids is presented. As an illustrative application, the cell is used for measuring the degradation of overheated edible oil through the evaluation of their dielectric constant.

In this paper, we describe an experiment for the undergraduate physical chemistry laboratory in which students determine the speed of sound in the gases He, N[subscript 2], CO[subscript 2], and CF[subscript 3]CH[subscript 2]F. The experimental apparatus consists of a closed acrylic tube containing the gas under study. White audio noise is injected…

In this article, the author describes two lessons in which students applied the scientific knowledge learned from studying offshore oil drilling to construct a fact-based argument on the topic and then communicate it to their policy makers, since public commentary was solicited. The students practiced using their scientific knowledge to…

Providing sustainable mobility is a major challenge that will require new vehicle and fuel technologies. Alternative and future fuels are the subject of considerable research and public interest. A simple approach is presented that can be used in science education lectures at the high school or undergraduate level to provide students with an…

The purpose of this paper is to explore and explain students' achievements in solving context-based gas exercises comprising the macroscopic and submicroscopic levels of chemical concepts. The influence of specific variables, such as interest in learning, formal-reasoning abilities, and visualisation abilities, is a significant factor that should…

A new, general approach to the organic chemistry laboratory is introduced that is based on learning about organic chemistry techniques and research methods by exploring the natural products found in local native plants. As an example of this approach for the Sonoran desert region, the extraction of jojoba oil and its transesterification to…

Purpose: This paper aims to identify the characteristics that a crisis unit should have to achieve effective learning after crisis. Literature has identified many relations between learning organizations and crisis; yet, there is a dearth of research on specific studies about crisis units and their post-crisis learning features. Thus, this paper…

Ethanol is the primary oxygenate in gasoline in the United States. Gasoline containing various percentages of ethanol is readily available in the market place. A laboratory experiment has been developed in which the percentage of ethanol in hexanes can easily be determined using the O-H and alkane C-H absorptions in an infrared spectrum. Standard…

Critical criminology will be applied to a discussion of environmental responsibility and the proposed controversial practice of 'fracking'. First, Green Criminology is discussed, as it seeks to re-direct the traditional focus of criminology onto patterns of crime and forms of criminality often marginalised by dominant research agendas and…

Nanotechnology allows the synthesis of nanoscale catalysts, which offer an efficient alternative for fuel cell applications. In this laboratory experiment, the student selects a cost-effective anode for fuel cells by comparing three different working electrodes. These are commercially available palladium (Pd) and glassy carbon (GC) electrodes, and…

Like many commodities, the price of gasoline continues to rise, and these price changes are readily observed in gas stations' signage. Moreover, algebraic methods are well suited to model price change and answer the student's question. Over the course of one ninety-minute block or two forty-five-minute classes, students build functions…

We propose two contrasting types of student decision-making based on social and cognitive psychology models of separate mental processes for problem solving. Informal decision-making uses intuitive reasoning and is subject to cognitive biases, whereas formal decision-making uses effortful, logical reasoning. We explored indicators of students'…
