A broadly applicable semester-long course-based undergraduate research experience (CURE)-inspired organic II laboratory course was developed from an engaging story supported by the current literature surrounding paraben use in consumer products. The project involves the synthesis of brominated parabens followed by an investigation into the…

Science labs should promote reasoning that resembles the work that scientists do. However, this is often not the case. We present a lab in which students strive to find out which of two models best describes a physics experiment. The quantification of measurement uncertainties--another topic that is often neglected in high school…

Lab-on-a-chip devices are a critical and emerging chemical technology. New pedagogical tactics that effectively capture both analytical chemistry concepts along with the design elements unique to these devices are necessary for effective integration in the undergraduate chemistry curriculum. This article develops a design-based learning laboratory…

This study presents a low-cost Arduino-based gas chromatography system that is suitable for teaching analytical chemistry in an undergraduate laboratory. The gas chromatography system is built with commonly available materials with a total cost less than $100. A Python code is also provided as a user interface that will record data and display the…

Trace metals when present in crude oil or fuels are of economic significance in refining and to the combustion engines that use them. Herein, we develop a laboratory activity that trains students on how to analyze crude oil samples for ash and trace metal content while giving them the opportunity to acquire skills needed as a quality control…

Look along the shelves holding your laboratory apparatus and into the demo-prep room, and you will find apparatus by "Cenco" and "The Central Scientific Company" sharing space with your new PASCO equipment. At the 1989 AAPT meeting in San Luis Obispo I was asked to talk about Cenco in honor of one of its long-term employers and…

Polymer Chemistry is a subject in the Chemistry Programs, student have a natural curiosity about polymeric materials, that we use in our everyday activities. Our proposal is to apply cooperative learning in the Interfacial polymerization of Nylon 6,10 experimentation. The specific objectives of our project can be summarized as: To identify the…

Science instructors assume that they have created their laboratory curriculum in such a way as to reflect an ideal science instructional laboratory, but students may not recognize this. A recent study used the Student Perceptions of the College Instructional Laboratory Survey (SPCILS) to examine students' perceptions of their science instructional…

Photo-oxidation is one of the main causes of oxidative deterioration in food. Understanding of the mechanisms of photo-oxidation is essential for food science students when pursuing careers in food safety and quality assurance. However, few food chemistry laboratories emphasize photo-oxidation. Thus, we develop a laboratory activity that trains…

This article examines tensions that professionals in healthcare settings in low-to-middle income countries (LMICs) face in the evolving field around surveillance of antimicrobial resistance (AMR). Few public health problems are of greater global importance today than AMR, that poses a threat to our ability to treat infections. In this context, the…

In a 1993 book review, E. Pearlstein asks, "Why don't textbook authors begin their discussion of magnetism by talking about magnets? That's what students have experience with." A similar question can be asked, "Why don't professors have students measure the force between permanent magnets in introductory physics labs?" The…

The aim of this study was to investigate pre-service science teachers' development of the quality of written arguments using science writing heuristic approach and pre-service science teachers' views about the science writing heuristic and its argument components in a General Biology Laboratory Course II. The study was carried out with 21…

The authors teach in a large, urban school district in the Midwest and typically a few students have parents who work in the sciences. One year, the authors were fortunate to have the child of the owner and head brewer of a local microbrewery. That coincidence set the stage for a major collaboration to bring the real world of chemistry and biology…

Restrictions due to the coronavirus (COVID-19) pandemic impacted the ability of faculty and students in exercise science to work in lab settings with human participants. The purpose of this study was to determine how exercise science faculty were impacted by COVID-19 restrictions with respect to access and use of exercise science lab and research…

Argumentation is a central epistemic process contributing to the generation, evaluation, and application of scientific knowledge. A key challenge for science educators and researchers is to understand how the important social and discursive ("social dialogic") dimensions of argumentation can be implemented in learning environments. This…
