For the present lab demonstration, we have developed fluorescent indicators to detect the end point in microscale redox titration of ferrous ions in permanganometry, cerimetry, and dichrometry. Microscale redox titrations were carried out effectively in micromolar(µM) concentrations and semi-microvolumes of the analytes. At the end point,…

Chen, Audrey; Tarapore, Eric; To, Allisen G.; Catolico, Davis M.; Nguyen, Kelly C.; Coleman, Melissa J.; Spence, Rory D. – Biochemistry and Molecular Biology Education, 2022
Widely used in research laboratories, immunohistochemistry (IHC) is a transferable skill that prepares undergraduate students for a variety of careers in the biomedical field. We have developed an inquiry-based learning IHC laboratory exercise, which introduces students to the theory, procedure, and data interpretation of antibody staining.…

Flaherty, Aishling – Journal of Chemical Education, 2022
Engaging in laboratory practical activities, developing laboratory practical skills, and, to a degree, even wearing laboratory protective equipment such as safety coats and goggles are all quintessential components of chemistry education. It is becoming quite common for institutions to invest in large-scale chemistry teaching laboratories, filling…

An undergraduate laboratory was developed as part of the Drugs for Neglected Diseases "initiative's" Open Synthesis Network. This activity aimed to develop new compounds efficacious against visceral leishmaniasis. Students successfully synthesized, purified, and characterized ten different benzoxazole amides that were sent for biological…

Pfaender, J.; Gratton, L. M.; Rosi, T.; Onorato, P.; Malgieri, M. – Physics Teacher, 2022
In the last decades spectroscopy began to play an essential role in physics education research with the recognition that atomic spectra constitute a good occasion to study the concepts of quantum mechanics. Moreover, activities in which atomic spectra are studied in order to understand star structure and evolution have proved particularly engaging…

Moya, Antonio Angel – Physics Teacher, 2022
Resistor--capacitor (RC) circuit labs help students, but most courses don't include them because of complications and cost. This work presents an easy and inexpensive Arduino-based lab on the charge and energy transfer between two capacitors with different values of the initial electric charge when they are connected through a resistor. Capacitors…

Aji, Mahardika Prasetya; Wulandari, Yuvita Kiki; Setiawan, Rudi; Karunawan, Jotti; Priyanto, Aan – Physics Education, 2022
In diffraction experiments, natural gratings often create uncommon diffraction patterns compared with those resulting from manufactured gratings. This study analyzed a unique diffraction pattern obtained by a grating from a flying termite wing. A ring-like diffraction pattern was formed because of the grating morphology from a flying termite wing,…

Using a qualitative approach based on grounded theory, this study explored the best practices of educational technology implementation in 2-year community college writing centers utilizing interviews with writing center administrators. Sociocultural development theory, as well as social learning theory, were applied to frame the results. Each…

Rachel D. Davidson; Thomas E. O'Loughlin; Theodore E. G. Alivio; Soon-Mi Lim; Sarbajit Banerjee – Journal of Chemical Education, 2022
In this laboratory experiment, students modify a series of surfaces and explore the effects of varying surface chemistry and texture on wettability by different probe liquids. Students begin by building a simple contact angle goniometer utilizing their mobile phone cameras. Next, they contrast the wettability of planar glass substrates…

Patrick I. T. Thomson; Paul Lamie – Journal of Chemical Education, 2022
This work further implements the "elements of inquiry" approach in a first-year undergraduate laboratory course, in a two-part inquiry sequence. In the first part of the sequence, students iteratively develop a "best-practice" TLC procedure. In the second part, students iteratively optimize a simple organic reaction using TLC,…

Mariana Orozco – Assessment & Evaluation in Higher Education, 2024
When instructors assess students' laboratory reports to appraise the underlying scientific reasoning, they disclose their own concerns, epistemological assumptions and beliefs about science. The analysis of such assessments (i.e. rubric-centred scores and corresponding justificatory comments) offer a wealth of insights that can be re-engaged in…

Cláudia S. Baptista; Pedro Oliveira; Laura Ribeiro – Journal of Academic Ethics, 2024
Animals are frequently utilized as a teaching-learning tool in multiple educational settings. It is, therefore, important to understand what students think about this topic, in particular medical and veterinary students as "life caregivers" and competent people for a dynamic and responsible social intervention. In this context, this…

Daniel Zarate; Kathleen Sheahan; Jingchun Li – Journal of College Science Teaching, 2024
Active learning provides students with meaningful and introspective roles in education. However, active learning is difficult to achieve in online class settings, particularly for biology laboratories initially designed to offer direct interactions with live organisms. During the COVID-19 pandemic, a transition to online learning was required in…

Monica Soma Hensley; Jessica A. Martin; Kali A. Miller; Kedmon N. Hungwe – Journal of Chemical Education, 2024
Reports of laboratory damage, personal injury, and death have triggered increasing concern over the academic safety culture and the safety education of those pursuing studies in the chemical sciences. Student-led laboratory safety teams (LSTs) within academic institutions serve as a new and expanding informal, bottom-up approach to improving the…
