Bohren, Craig F. – Physics Teacher, 2016
In his interesting and informative book "Is That a Fact?," Joe Schwarcz avers that pigs do not sweat and the saying "sweating like a pig" originates in iron smelting. Oblong pieces of hot iron, with a fancied resemblance to a sow with piglets, cool in sand to the dew point of the surrounding air, and hence water condenses on…

Tyler Garcia – ProQuest LLC, 2024
One way to bring about change in higher education is to introduce professional development programs for higher education, however these programs have been found to be ineffective at promoting positive change for individuals and departments. To address the need for better programs, I worked on two projects: one project attempts to identify a way to…

Gascon, Katherine N.; Weinstein, Steven J.; Antoniades, Michael G. – Journal of Chemical Education, 2019
The effect of surfactant adsorption on surface tension, as well as associated thermodynamic concepts are introduced in a laboratory experiment designed for undergraduate students. Using a reliable and accessible method, students measure the surface tension of aqueous solutions at different concentrations of sodium dodecyl sulfate. Students collect…

Silverstein, Todd P.; Williamson, J. Charles – Biochemistry and Molecular Biology Education, 2019
We have developed a laboratory project in which students prepare liposomes, expose them to hyperosmotic and hypoosmotic solutions, and follow the resulting shrinking and swelling (respectively) with laser light scattering. Each light intensity transient can be fit to an exponential decline or rise, with the decay constant (k) and the amplitude…

Perea Martins, J. E. M. – Physics Education, 2018
This work describes a simple experiment to measure the resistor temperature as a function of the applied power and proves that it is an efficient way to introduce some important physical concepts in classroom, including the Joule's first law, hot-spot temperature, thermal resistance, thermal dissipation constant, time constant and the Newton's law…

Rybolt, Thomas R.; Mebane, Robert C. – Journal of Chemical Education, 2018
A low-cost alternative to the typical scientific laboratory water bath or a hot plate stirrer water bath is proposed. Readily available immersion circulators have been developed for sous vide cooking. These precision cookers are designed to maintain water at an exact temperature and thus are well-suited for the similar laboratory requirements of a…

Lancor, Rachael; Lancor, Brian – Physics Teacher, 2018
Project-based learning has been shown to be an effective pedagogical strategy that motivates students and thus promotes learning. In this article we describe a project-based unit centered on the physics of solar cookers (Fig. 1 and 3). Our goal was to elevate the solar cooker from a summer camp activity to a college-level project that could be…

Kohlstedt, Kevin L.; Jackson, Nicholas E.; Savoie, Brett A.; Ratner, Mark A. – Journal of Chemical Education, 2018
Organic semiconductors (OSCs) are making great progress as active components in alternative energy and flexible electronics technologies that are of interest to many undergraduates. However, in materials governed by the confluence of multiple length scales (molecular (Angstrom), intermolecular (nm), domain (100s nm)), providing a pedagogically…

Halilovic, Asila; Mešic, Vanes; Hasovic, Elvedin; Vidak, Andrej – Journal of Baltic Science Education, 2021
Conventional teaching about the law of conservation of mechanical energy (LCME) often results with students trying to solve problems by remembering similar problems they already covered in classes. Consequently, many students fail to transfer their knowledge to simplest real-life problems. Therefore, a pre-test-post-test quasi-experiment was…

Lenzer, Stefanie; Smarsly, Bernd; Graulich, Nicole – International Journal of Science Education, 2020
The need to develop clean-energy storage systems, harvesting technologies, and new functional materials are but a few of the many contemporary challenges in the domain of science today. To address these challenges, problem solving has become a key skill of the 21st century. It is generally documented, however, that experts and students differ in…

Brown, Patrick – Science and Children, 2019
Students come to class with ideas about science content and the practices used to generate knowledge. Their lived experience provides them with basic ideas about how the world works. Tapping into their innate understandings and testing their ideas allows them to construct a more accurate understanding. Research shows that all students are ready to…

Browning, Fred; Moore, Kaitlyn; Campos, Jennifer – Physics Teacher, 2019
The possibility of negative temperatures on the Kelvin scale is intriguing and confusing simultaneously. This is because students are used to thinking of temperature as a measure of the internal energy of a system. While this concept is good for many systems, it does not work for all systems. Nuclear and electron spin systems, along with lasers…

Shao, Michael; Shiflett, Mark B. – Chemical Engineering Education, 2021
Simulation software has experienced growing interest in chemical engineering curriculums for its usage in commercial engineering practices. This article describes the ASPEN Plus® version 10 (V10) simulations and a student teach students approach to integrate ASPEN in the chemical engineering curriculum at the University of Kansas (KU). Videos,…

Stylos, Georgios; Sargioti, Aikaterini; Mavridis, Dimitrios; Kotsis, Konstantinos T. – International Journal of Science Education, 2021
Although students are expected to finish school having a solid understanding of scientific concepts, they graduate from universities maintaining their former misconceptions in several fields, like physics. This study aims at validating the Thermal Concept Evaluation (TCE) test for university student's misconceptions of thermal concepts in everyday…

Pagliarini, Cassiano Rezende; de Almeida, Maria Jose P. M. – Physics Education, 2021
The role of peer and teacher mediation in discussions about two original scientific texts in the final year of high school in Brazil is explored in this study. A text by James C. Maxwell, deals with the characterisation of light as an electromagnetic phenomenon, and refers to the continuous manner of the distribution of energy by radiation in…
