Quinacridone red and violet are visually different colors, an observation confirmed by their visible reflectance spectra and CIE L*a*b* coordinates. However, their IR spectra are extremely similar. Though chemically identical, the two quinacridones are polymorphs. In this experiment, designed for and tested by nonscience majors, the pigments are…

This brief focuses on the important role that math requirements contribute to inequity in access to college, in particular the value placed on calculus, even though it is not an essential course for students who are seeking non-STEM degrees. The boost earned by students who are fortunate enough to have access to calculus, a benefit unequally…

Lakes are artists' pigments made from colorants bound to an inert substrate, usually hydrated aluminum oxide. Before the late 19th century, lakes were made from natural pigments extracted from plants and insects, extracted either directly from the dyestuff or indirectly from waste materials generated in the manufacture of dyed textiles. The first…

Buckminsterfullerene (C[subscript 60]), along with diamond and graphite, appears in many chemistry textbooks as an example of an allotrope of carbon. This communication describes a hands-on activity to explore the characteristic structure of C[subscript 60] through the construction of a structural model using transistors and plastic tubes…

Like many other universities, Musical Acoustics is offered at our school as a lab-based course fulfilling general science requirements for non-majors. The course has been team-taught by a physics professor and music professor since its earliest inception and, by far, the most popular unit explores room acoustics through a variety of activities and…

Experienced provers employ a host of skills when assessing the validity of a justification, often without names for those skills. This paper offers an introduction to a lens called Toulmin analysis that can help make sense of this process. Then this paper describes both an in-class module to help students learn to apply Toulmin analysis and…

A perennial goal of science educators is to develop functional scientific literacy in their students, especially those who will not become professional scientists. This article provides an example of implementing a socioscientific issues approach in an undergraduate environmental science course that enables students to develop the knowledge,…

Kombucha, a popular probiotic beverage, contains detectable concentrations of ethyl alcohol. To be sold as a nonalcoholic product, alcohol concentrations in kombucha must be shown to be less than 0.5% by volume. This paper describes the use of an inexpensive, commercially available sensor to reliably and accurately measure alcohol concentrations…

Colleges throughout the United States typically expect their students to take at least one course in the sciences to fulfill liberal studies curriculum requirements. For nonscience majors, the choice of science class can include introductory chemistry, introductory biology, and astronomy, among others. Based upon interactions both in and out of…

A course on the economics of sports provides a unique opportunity to the economics department but confronts the instructor with unique challenges. Students in such a class are likely to be more heterogeneous and more likely to enter the class with inappropriate expectations than is the case for a typical upper-level economics elective. The author…

Throughout the 21st century, the discipline of developmental education has come under fire for low success rates and has created a great deal of controversy. This has especially been the case for developmental math. Over the years, there have been many initiatives to improve student success and completion in developmental math. Some have succeeded…

A rudimentary level of scientific literacy is necessary in the general public. At the undergraduate level, this literacy can be achieved through general education courses offered in areas of natural sciences. Over the past several years, practical courses have been developed to make the teaching of chemistry concepts in the laboratory more…

Using the backward design model, the author of this article surveys and connects the economic competencies literature evolving from Hansen with the literature on literacy-targeted principles courses. He makes the case why departments should offer LT principles courses--which focus on higher-level mastery of a shorter list of concepts that students…

This article presents an experience in teaching mathematical thinking through games in a math course for non-science majors. The course described here has run twice on the campus of Sam Houston State University and is a combination of escape room pedagogy and game-based pedagogy. From these courses, I note an increased engagement of students with…

This paper reports a demonstration of a 90 min on-demand class where a chemical experiment is performed to educate nonscience majors on surfactants. First-year undergraduate students perform the water ball in a water bottle experiment at home and learn about the structure and properties of organic compounds in the demonstration. The experiment is…
