Gladys, M. J.; Furst, J. E.; Holdsworth, J. L.; Dastoor, P. C. – Physical Review Physics Education Research, 2023
The multiple-choice section of the final examination for the first-year Advanced Physics I course at the University of Newcastle, Australia between 2010 and 2018 was investigated for gender bias. A Mantel-Haenszel analysis revealed that approximately 20% of the multiple-choice questions exhibited statistically significant gender bias. A schema for…

Lahane, Rohan D.; Bhatt, Harsh R.; Paranjpye, Arvind – Physics Education, 2022
Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an…

Coelho, Ricardo Lopes – Physics Education, 2022
The pendulum was an important scientific instrument in the 17th century. It became a typical textbook problem in the 18th century. After the introduction of vectors in physics in the 1890s, the pendulum problem started to be progressively solved in the manner we know nowadays from introductory mechanics courses. Starting from "F = ma"…

Theilmann, Florian – Physics Education, 2022
Ever since Newton's groundbreaking work on the composed nature of light, additive colour mixing (and its laws) are subject to the interest of physicists as well as other sciences. In this paper, we present a setup for simple lab or home experiments on additive colour mixing and the laws of colour mixing. Students use the screen of a laptop or…

Jason M. May – Physical Review Physics Education Research, 2023
[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] Physics instructional labs have long been an area of pedagogical innovation and educational research. While current stakeholders in instructional labs are undoubtedly aware of the day's concerns, reform efforts, and empirical research…

Gerard G. Dumancas; Noemi Carreto; Oliver Generalao; Guoyi Ke; Ghalib Bello; Arnold Lubguban; Roberto Malaluan – Journal of Chemical Education, 2023
Chemometric techniques such as partial least-squares (PLS) regression have been applied with huge success to a wide array of chemical problems including multicomponent analysis of analytes in complex mixtures. Despite this, there are few examples of laboratory pedagogical exercises that involve students in the acquisition of chemical data from…

Tyler A. Shaffer; Carlos U. Herrada; Avery M. Walker; Laura D. Casto-Boggess; Lisa A. Holland; Timothy R. Johnson; Megan E. Jones; Yousef S. Elshamy – Journal of Chemical Education, 2023
Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

Grebenev, Igor V.; Kazarin, Petr V.; Lebedeva, Olga V. – Physics Education, 2022
The article describes a new version of a demonstration experiment for the Maxwell distribution. In the first part students analyse the applicability of the Gaussian distribution to the projection of the particle velocities in the suggested experiment. Further, students observe two-dimensional distribution of particles by the modulus of velocity in…

Wang, Aili; Ma, Sihui; Zhu, Yeyuan; Zou, Liang; Zhao, Gang – Journal of Chemical Education, 2022
Photo-oxidation is one of the main causes of oxidative deterioration in food. Understanding of the mechanisms of photo-oxidation is essential for food science students when pursuing careers in food safety and quality assurance. However, few food chemistry laboratories emphasize photo-oxidation. Thus, we develop a laboratory activity that trains…

Li, Yunhua; Chen, Cuixue; Ye, Meiling; Imbault, Alexander Luis – Journal of Chemical Education, 2022
Organizing undergraduates in chemistry, energy engineering, and chemical engineering specialties to participate in an energy transformation experiment can encourage them to think about the impact of human activities on nature and stimulate them to learn more about the topic. This laboratory experiment demonstrates a general approach to the…

Thomas D. Varberg – Journal of Chemical Education, 2022
An experiment for the undergraduate physical chemistry laboratory is described in which the Raman spectrum of liquid "para"-difluorobenzene is recorded and assigned. A density functional theory (DFT) calculation of the 30 normal modes of the molecule is undertaken using computational chemistry software. Students use group theory to…

Stephens, Isaiah O.; Thomas, Elizabeth M. – Journal of Chemical Education, 2022
Apurinic/apyrimidinic (AP or abasic) sites are deoxyribonucleic acid (DNA) lesions that result from the loss of a nucleobase by hydrolysis of the "N"-glycosyl bond. AP sites are the most frequent lesions in cells and are caused by environmental and cancer therapeutic genotoxins. Herein, the bicinchoninic colorimetric assay, typically…
