While gender parity has been achieved in overall science degree earning, large gaps still exist within many science disciplines. Further, studies addressing gender inequity in science often ignore a large source of undergraduate science degree earners: those who enroll in science courses intending to pursue careers in health or medicine. This…

An iridium(III)-mediated C-H functionalization sequence involving a concerted cyclometalation-deprotonation/migratory insertion pathway is reported for the undergraduate chemistry laboratory. The air- and water-stable iridacycle intermediates are readily isolated and characterized by NMR spectroscopy. Both steps of the experiment are performed at…

[This paper is part of the Focused Collection on Astronomy Education Research.] This paper presents the first item response theory (IRT) analysis of the national data set on introductory, general education, college-level astronomy teaching using the Light and Spectroscopy Concept Inventory (LSCI). We used the difference between students' pre- and…

The angular velocity of a spinning object is, by standard, measured using a device called a tachometer. However, by directly using it in a classroom setting, the activity is likely to appear as less instructive and less engaging. Indeed, some alternative classroom-suitable methods for measuring angular velocity have been presented. In this paper,…

As chemists, we understand that science is more than a set of disconnected facts. It is a way of investigating and understanding our natural world that involves things like asking questions, analyzing data, identifying patterns, constructing explanations, developing and using models, and applying core concepts to other situations. This paper uses…

A high performance liquid chromatography (HPLC) experiment for the upper level analytical chemistry laboratory is described. The students consider the effect of mobile-phase composition and pH on the retention times of ionizable compounds in order to determine the acid dissociation constant, K[subscript a], of a phenolic acid. Results are analyzed…

Improving students' understanding of how science works requires explicit instruction. Here, we test the efficacy of a module based on two previously published activities (the "Cube Puzzle" and the case study "Asteroids and Dinosaurs") that teach how science works to college science majors. Students also use the How Science…

Instructors struggle with the amount of information they are expected to teach in the limited number of hours that are available in undergraduate human anatomy and physiology laboratories and students struggle with how to learn the terminology. When a snowstorm closed our campus, labs were cancelled for five of our fourteen lab sections. The…

This study presents the results of an investigation of the undergraduate student perception of fieldwork, specifically in the context of the affective domain, and considers the effectiveness of field-based training as a pedagogical tool. Fieldwork provides the learner with a deep and immersive learning environment, where they are required to apply…

Randy Olson's book, "Don't Be Such a Scientist: Talking Substance in an Age of Style", was used to supplement a senior seminar in nanomaterials. While students learned about the chemistry behind useful properties of nanomaterials, they also analyzed how nanomaterials applications are presented to the public through advertising, science…

Thirty-six students enrolled in Organic Chemistry II participated in individual, semistructured, think-aloud interviews about the factors that contribute to the stability and reactivity of organic species in the context of unimolecular and bimolecular nucleophilic substitution and elimination reactions. The students were provided with the…

Emphasizing scientific literacy in the core science curriculum promotes informed students within a liberal arts education. In our Introduction to Biology course, which enrolls predominantly humanities majors in their final science course of their academic careers, we designed a project to advance these analytical processes through the deliberate…

The introduction of electric circuit simulation software for undergraduate students in a general physics course is proposed in order to contribute to the constructive learning of electric circuit theory. This work focuses on the lab exercises based on dc, transient and ac analysis in electric circuits found in introductory physics courses, and…

In this paper, we propose a simple experimental apparatus that can measure the force variation over time to study the impulse-momentum theorem. In this proposal, a body attached to a rubber string falls freely from rest until it stretches and changes the linear momentum. During that process the force due to the tension on the rubber string is…

"Manga" are graphic novels that are considered to have the potential to effectively convey concepts and engage readers. The efficacy of "manga" has been validated for chemical safety education to students in three universities in Japan, Taiwan, and Thailand. Students were asked to examine a photo to identify hazards and…
