Despite the existent gender parity in undergraduate biology degree attainment, gendered differences in outcomes are prevalent in introductory biology courses. Less is known about whether these disparities persist at the upper-division level, after most attrition is assumed to have occurred. Here, we report the consistent presence of gender equity…

The development of an enzyme-mediated reaction for the first-year general, organic, and biological chemistry (GOB) teaching laboratory is of significant importance so that the factors that affect enzyme-mediated reactions can be adequately demonstrated, reinforcing the lecture portion of the GOB course. Some of the factors that affect these types…

This laboratory experiment introduces the fundamentals of electrochemical techniques to the undergraduate students by developing a simple and cost-effective miniaturized electrochemical setup for detecting UV-induced DNA damage. This is an imperative experiment, as it provides students first-hand experience with electrochemical techniques while…

This communication presents a partial historical summary of some of Iowa State University's Chemistry Department teaching response to the shift to online course delivery caused by the COVID-19 pandemic. The observations reflect discussions between and informal surveys of an instructor cohort that impacted roughly 1200 undergraduate students. These…

Educators are recognizing the potential power of immersive virtual reality (IVR) to allow learners to experience previously intangible firsthand phenomena, such as atoms and molecules. In this study, an IVR simulation of a complex gene regulation system was co-designed with an undergraduate microbiology course instructor. The course, with 234…

Background: Understanding student motivational factors such as test anxiety and science confidence is important for increasing retention in science, technology, engineering, and math (STEM), especially for underrepresented students, such as women. We investigated motivational metrics in over 400 introductory biology students in Norway, a country…

The cyclic format of the undergraduate physics curriculum depends on students' ability to recall and utilize material covered in prior courses in order to reliably build on that knowledge in later courses. However, there is evidence to suggest that people often do not retain all, or even most, of what they learned previously. How much information…

This study focused on exploring and evaluating students' views of the Nature of Science in the context of undergraduate chemistry laboratory. Thirty-six undergraduate students doing a laboratory course in upper division physical chemistry were assessed using an open-ended instrument and assessment criteria that categorise them in three levels of…

In this study, customized videos and chapter handouts served as pre-class materials for semi-flipped General Chemistry II courses. Face-to-face class time involved engaging students in interactive problem-solving sessions on the board with the instructor and collaborative group activities. During the interactive problem-solving sessions, students…

This study compared the performance of two audience response systems (ARSs) without students requiring smartphone technology or Internet access during problem-based learning (PBL) activities. Clicker handsets linked to a radio frequency (RF) receiver and paper voting cards, known as Plickers, which display a QR code (two-dimensional barcode) that…

Microplastic contamination of the environment is a major concern but detecting such contamination presents a challenge, particularly for particles <0.1 mm in size. Community scientists and students who participated in a plankton monitoring program and routinely examined samples of seawater using brightfield microscopy, often found fragments and…

Racial or ethnic isolation may negatively impact physics graduate students' academic and professional experience. An interview study with 16 doctoral students who were considered to be particularly at risk of such isolation found that (i) the students interviewed are mostly not the only member of their racial or ethnic group in their programs;…

Research project modules are a key part of UK undergraduate and postgraduate bioscience degree programmes. Report marking invariably uses two assessors, but marking models are mixed with some institutions using two independent markers and others using the project supervisor as one of the assessors. This latter model is controversial with critics…

Teaching cosmology at the undergraduate or high school level requires simplifications and analogies, and inevitably brings the teacher into contact with at least one of the pedagogical interpretations of the expanding Universe. The by far most popular interpretation holds that galaxies in an expanding Universe are stationary, while space itself…

In this article, physical quantities related to the motion of a parachute system in the framework of Newton's law of mechanics guide an informal approach to the mathematical concept of function. Furthermore, a graphical simulator that enables visualization of the fall of object-parachutes system is presented. The article is aimed at students and…
