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…

Though several conceptual inventories have been developed for thermal physics, none target upper-division material and all focus specifically on thermodynamics without including statistical mechanics content. In this paper, we outline the development process of an upper-division thermal physics assessment that captures both thermodynamics and…

The study of genetics centers on how encoded information in DNA underlies similarities and differences between individuals and how traits are inherited. Genetics topics covered in a wide variety of undergraduate biology classrooms can relate to various identities held by students such as gender identity, disability, and race/ethnicity, among…

Visual representations, such as pathway models, are increasingly being used to both communicate higher education science, technology, engineering, and mathematics (STEM) education program evaluation plans as well as accurately represent complex programs and the systems within which the educational programs reside. However, these representations…

A growing body of educational research is demonstrating the improvements to learning gains and student performance that can be promoted by a flipped-classroom model in university chemistry courses. Usually, a core aspect of the flipped-class model is the student viewing of a preclass instructional video, allotting time for an in-class activity…
