We developed a gas-phase Fourier Transform InfraRed Scientific Instrument Simulator (FTIR-SIS, https://ftir.rastonlab.org/) in response to the unavailability of one during the COVID-19 pandemic lockdown of 2020. It features an interactive interface that encourages students to explore different components of a typical FTIR, and it allows them to…

Aim/Purpose: This case study examines students' affective responses to and relationships with two-dimensional (2D) and 360° videos that were experienced with or without low-cost virtual reality (VR) headsets. Background: The prior research on low-cost VR technology is scant. Schools and universities are not financially able to purchase tens or…

We designed and tested a 3D motion tracking system which displays acquired and derived data using augmented reality. This setup, based on a virtual reality headset and its controllers, is a relatively low-cost, high-precision, six degrees of freedom, high-speed, multiple-objects tracking device. This apparatus proves to be a very high-quality…

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.…

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…

Physics is a tough and challenging topic. Facilitating the learning of physics requires an innovative and constructivist view of teaching that promotes an active learning environment and an effective implementation of educational technology. The purpose of the study is to investigate whether the use of computer simulations combined with hands-on…

Learning quantum mechanics is challenging, even for upper-level undergraduate and graduate students. Research-validated interactive tutorials that build on students' prior knowledge can be useful tools to enhance student learning. We have been investigating student difficulties with quantum mechanics pertaining to the double-slit experiment in…

Traditionally, cytotechnology (CT) students have been trained by using light microscopy (LM) and glass slides. However, this method of training has some drawbacks. Several other educational programs with similar issues have incorporated virtual microscopy (VM) in their curricula. In VM, the specimens on glass slides are converted into virtual…

In 1879, in the midst of the debate between English and continental scientists about the nature of cathode rays, William Crookes conducted an experiment in which a small mill or "paddle wheel" was pushed along tracks inside a cathode ray tube (CRT) (similar to that shown in Fig. 1) when connected to a high-voltage induction coil. Crookes…

The recent celebration of the discoveries made by Galileo four centuries ago has attracted new attention to the refracting telescope and to its use as an instrument for the observation of the night sky. This has offered the opportunity for addressing in the classroom the basic principles explaining the operation of the telescope. When doing so, a…

The commercial simulator Aspen Chromatography was employed to study and optimize an important new industrial separation process, weak partitioning chromatography. This case study on antibody purification was implemented in a chromatographic separations course. Parametric simulations were performed to investigate the effect of operating parameters…

The increasing complexity of human body models enabled by advances in diagnostic imaging, computing, and growing knowledge calls for the development of a new generation of systems for intelligent exploration of these models. Here, we introduce a novel paradigm for the exploration of digital body models illustrating cerebral vasculature. It enables…

Described is the use of a microcomputer and computer software to simulate the use of geological equipment. The technique uses pictures of the control panel (with switches and dials that can be activated) and a story board that can provide the simulation. A simple seismograph is used as an example of possible simulations. (RH)

Examines present and future applications of computers in high-energy physics. Areas considered include high-energy physics laboratories, accelerators, detectors, networking, off-line analysis, software guidelines, event sizes and volumes, graphics applications, event simulation, theoretical studies, and future trends.

For colleges/universities, rapid instrument development poses a dilemma, since laboratory teaching instruments rapidly become obsolete and money available for replacing them is dwindling. Discusses role of sophisticated computer simulations, nontraditional educational materials, and part-time work-study opportunities as possible solutions to the…
