Joseph S. Elias – Journal of Chemical Education, 2024
We report the design of a low-cost electrochemical workstation and open-source graphical user interface capable of performing a variety of electrochemical methods in an undergraduate teaching laboratory. The instrument--based on the popular Arduino microcontroller board--can be constructed from common components for $40 USD. The modular design of…

David Mainka; Julius Krause; Linus Großmann; Andreas Link; Lukas Schulig – Journal of Chemical Education, 2023
The pharmaceutical industry relies heavily on analytical techniques for identifying and characterizing drug compounds. In this experiment, undergraduate pharmacy students explored the applications of near-infrared spectroscopy for pharmaceutical analysis and its potential for identifying patterns and relationships among pharmaceutical samples. In…

Torres, David J.; Romero, Andres; Colgan, Wes, III; Ricoy, Ulises M. – Advances in Physiology Education, 2021
Undergraduates use a spike sorting routine developed in Octave to analyze the spiking activity generated from mechanical stimulation of spines of cockroach legs with the inexpensive SpikerBox amplifier and the free software Audacity. Students learn the procedures involved in handling the cockroaches and recording extracellular action potentials…

Matsubara, Yasuo – Journal of Chemical Education, 2021
A modern cybernetic potentiostat plays a significant role in realizing various electrochemical measurements. This technology report describes a general-purpose, scalable, handheld (10 cm[superscript 2]), yet affordable hardware-software framework for a potentiostat, galvanostat, and electrochemical impedance spectrometer with high capabilities:(1)…

Coramik, Mustafa – Physics Education, 2021
Teaching materials used in distance education are generally obtained from the internet as ready-made by teachers. Materials such as simulation, animation and presentation are usually limited to the frame drawn by the creator and do not allow changes outside this limit. In addition, many of these types of materials do not have a feedback mechanism.…

Krumphals, Ingrid – Physics Education, 2019
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.…

Vollmer, Michael; Möllmann, Klaus-Peter – Physics Education, 2018
Video analysis with a 30 Hz frame rate is the standard tool in physics education. The development of affordable high-speed-cameras has extended the capabilities of the tool for much smaller time scales to the 1 ms range, using frame rates of typically up to 1000 frames s[superscript -1], allowing us to study transient physics phenomena happening…

Ballester, Jorge; Pheatt, Charles B. – Physics Teacher, 2012
The study of motion is central in physics education and has taken many forms as technology has provided numerous methods to acquire data. For example, the analysis of still or moving images is particularly effective in discussions of two-dimensional motion. Introductory laboratory measurement methods have progressed through water clocks, spark…

Ward, R. Bruce; Sienkiewicz, Frank; Sadler, Philip; Antonucci, Paul; Miller, Jaimie – Astronomy Education Review, 2013
We describe activities created to help student participants in Project ITEAMS (Innovative Technology-Enabled Astronomy for Middle Schools) develop a deeper understanding of picture elements (pixels), image creation, and analysis of the recorded data. ITEAMS is an out-of-school time (OST) program funded by the National Science Foundation (NSF) with…

Molina-Bolivar, J. A.; Abella-Palacios, A. J. – European Journal of Physics, 2012
The aim of this paper is to introduce a simple and low-cost experimental setup that can be used to study the eddy current brake, which considers the motion of a sliding magnet on an inclined conducting plane in terms of basic physical principles. We present a set of quantitative experiments performed to study the influence of the geometrical and…

A Heuristic Algorithm for Planning Personalized Learning Paths for Context-Aware Ubiquitous Learning
Hwang, Gwo-Jen; Kuo, Fan-Ray; Yin, Peng-Yeng; Chuang, Kuo-Hsien – Computers & Education, 2010
In a context-aware ubiquitous learning environment, learning systems can detect students' learning behaviors in the real-world with the help of context-aware (sensor) technology; that is, students can be guided to observe or operate real-world objects with personalized support from the digital world. In this study, an optimization problem that…

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…

Greene, John Richard T. – Anatomical Sciences Education, 2009
This article discusses factors in the design, commissioning, project management, and intellectual property protection of developments within a new clinical anatomy facility in the United Kingdom. The project was aimed at creating cost-effective facilities that would address widespread concerns over anatomy teaching, and support other activities…

Yarnall, Louise; Shechtman, Nicole; Penuel, William R. – Journal of Science Education and Technology, 2006
A variety of handheld applications and curricular materials have been developed to support inquiry science learning in recent years, but there are few handheld-supported assessment activities available to teachers. In Project WHIRL, researchers from SRI International worked in partnership with teachers from Beaufort County School District (SC) to…
