Introductory anatomy and physiology courses are either taught as discipline-specific courses (human anatomy and human physiology) or integrated sequences [combined human anatomy and physiology (A&P I and A&P II)]. This variation suggests there is no agreed upon pedagogical standard for teaching introductory anatomy and physiology. We…

In an upper-division interdisciplinary laboratory experiment, students use Raman spectroscopy to highlight how the overall structure and conformational order of lipid bilayers can be influenced by their individual phospholipid composition. Students prepare a supported lipid bilayer, as a model cell membrane, by spreading liposomes made of various…

Graduate education in chemistry typically follows an apprenticeship model, primarily aimed at preparing students for academia; however, the inclusion of teaching within this apprenticeship is not always clear as faculty, students, and other stakeholders do not agree on the need for instructional training. Despite the variability in training, a…

In undergraduate classrooms, a majority of chemistry discoveries introduced are by white men and a small group of white women. There is greater online representation of chemists of diverse backgrounds, but the emphasis on diversity is mainly based on a monthly theme from Black History Month to Women's History Month. The "Diversity in…

The chemical enterprise is recognizing that inclusive and equitable environments are essential to its mission and advancement. As such, the education and training of chemists requires a reassessment of how academic programs integrate diversity, equity, and inclusion (DEI) as a core principle of educational quality. This article describes a 3-year…

The Arduino microcontroller is finding its way into labs throughout undergraduate physics curricula, from introductory courses to a variety of beyond-the-first-year laboratory classes. At Davidson College, they use Arduinos in a gateway STEM course for students who are interested in energy and the environment. This article describes how students…

In the 1930s, the teaching staff of the University of Chicago devised a clever way to deliver experimental data to their introductory students without meeting them in the laboratory. The university's curriculum included a required Introductory Course in the Physical Sciences. There were probably too many students to allow for a standard…

The cases of constant and quadratic damping of free oscillations are missing from standard textbooks, even at college and university level. The case most examined is that of linear damping, the reason being that the student can work out a closed form which describes all stages of motion. The case of constant damping is straightforward to be…

Experimental results are presented concerning the motion of a ball that bounces up an incline a few times then bounces back down again. The number of bounces up the incline is typically small since the speed of the ball in a direction parallel to the incline decreases rapidly, not only during each bounce but also while the ball is in the air. The…

Using crystal structure data, site directed mutagenesis, and real-time kinetic assays, students designed, expressed, and purified engineered mutants of human insulin-degrading enzyme (IDE). Students designed their own IDE mutants following "in silico" analysis, used inverse PCR to generate mutant plasmid expression constructs, expressed…

Raman scattering is a powerful tool for revealing the vibrations of molecules, but as a nonlinear optical phenomenon, its signals can change via mechanisms like resonance enhancement that have no direct analogue in infrared spectroscopy. In this work, complementary measurements conducted on 4-nitrophenol and its conjugate base allow students to…

As electrochemistry continues to gain broader acceptance and use within the organic chemistry community, it is important that advanced undergraduate students are exposed to fundamental and practical knowledge of electrochemical applications for chemical synthesis. Herein, we describe the development of an undergraduate laboratory experience that…

The overhead mechanical stirrer is a versatile and valuable tool for the laboratory. Even a low-end mechanical stirrer is rather expensive and can pose serious safety concerns for use by high school or undergraduate students. The construction and application of a low-cost overhead mechanical stirrer is described in this work. The mechanical…

Measurement uncertainty is a key topic in the university physics laboratory curriculum. In this study, we investigate students' ability to draw conclusions from measurement data and reasoning about measurement uncertainty in inquiry labs. This investigation centres around a task where students conclude whether measurements from two experiments…

Spatial reasoning is one of the most challenging skills to master in the science, technology, engineering, and mathematics (STEM) fields. This article reports the results of a teaching intervention that involved using wooden blocks to enhance the development of spatial reasoning in an undergraduate-level introductory geology course. Wooden blocks…
