An innovative food laboratory for a chemistry of food and cooking course has been developed for nonscience majors and under-represented students in science. To help these students succeed in science, a laboratory was designed to engage students using food and cooking as a medium for building a stronger foundation in chemistry. Each food laboratory…

Polymers and nanochemistry are important facets of chemistry. In this experiment, students synthesize monodispersed poly(methyl methacrylate) nanospheres from the addition or chain polymerization of a rapidly stirred aqueous mini-emulsion of methyl methacrylate. The 2,2'-azobis(2-methylpropionamidine) dihydrochloride serves as a heat activated,…

Limiting case analysis (LCA) is important to practicing physicists. Yet, there is little concrete guidance for physics educators, and a lack of consensus in the research community about how to help students learn, and learn from, limiting case analysis. In this study, we first review existing literature to find commonalities and variations in how…

As COVID-19 restrictions are removed, instructors are faced with two questions: should the course be taught online, via mixed-mode, or through traditional methods, and what effect did online instruction have on students in the course in regards regarding enrolled across eight semesters of metabolism courses using traditional, mixed-mode, and…

Eleven different laboratory experiments were designed and executed throughout a semester to provide a meaningful research experience for 23 undergraduate biochemistry majors at UTSA. The topic of the semester was based on the idea of exploring new aspects to enhance our understanding of how the human body uses cytochrome P450 enzymes to metabolize…

The electrolysis of water to produce hydrogen is a critical step in many green chemistry processes. The key to the efficiency of water electrolysis is the synthesis of an appropriate electrocatalyst. Three-dimensional (3D) printing is an increasingly important part of many industrial processes. In this study, we propose an efficient laboratory…

Descriptive statistics involves summarizing and organizing data so that they can be easily understood. Even though these are basic and simple concepts, many applied science students have misconceptions about their use in applied experiments in the laboratory. Students usually receive limited or no training in how to understand the meaning of the…

In 2020 a global pandemic forced biology teaching laboratories to move to remote instructional environments. In this article, we present data on student perceptions of laboratory instruction modality as experienced pre-, during, and post-pandemic. We designed a survey to evaluate students' perception of key components of scientific critical…

Scanning probe-based microscopes (SPMs) are widely used in biology, chemistry, materials science, and physics to image and manipulate matter on the nanoscale. Unfortunately, high school and university departments lack expensive SPM tools and materials microscopy activities to educate a large number of students in this vital SPM imaging technique.…

Several traditional chemistry lab experiences were replaced with a problem-based learning (PBL) experience in a university general education, conceptual chemistry course. Students worked in small groups on an authentic chemistry problem in which each student played a different role (Scientist, Engineering, Marketing Manager, Safety Officer, or…

Self-regulated learning (SRL) models provide a framework for understanding the observed variance of student performance in geoscience learning contexts. Instructors can potentially use a SRL framework to support students in self-identifying the specific approaches to learning they use when engaging in geoscience learning situations (coursework,…

This study examined assessment item difficulty patterns in two energy aspects, energy source/form/transfer and energy degradation/conservation, across and within science disciplines. The participant students were taking at least one college-level introductory science course. Findings showed a common pattern of item difficulties for the two energy…

Despite advances in software development, symmetry-related topics are among the most important yet confusing concepts in crystallography training for chemistry students who routinely use small-molecule crystallography in their scientific study. The case-based learning approach is very effective in stimulating students' interests in self-exploring…

We use the population decline of the monarch butterfly as a central phenomenon to support data analysis and scientific argumentation skills and to motivate inquiry and content learning in intermediate college-level biology courses. Students practice analyzing population trends, critically evaluate scientific articles that debate the causes and…

In this laboratory experiment, the synthesis and characterization of H[subscript 5]PV[subscript 2]Mo[subscript 10]O[subscript 40]@Cu[subscript 3](BTC)[subscript 2] (denoted as NENU[subscript -9], H[subscript 3]BTC = 1,3,5-benzenetricarboxylic acid) and its application in fuel desulfurization were performed. This experiment is designed for advanced…
