During the COVID-19 pandemic, an at-home enzyme assay was developed for a biochemistry laboratory course at Arizona State University. The experiment was designed to use items that could be easily obtained and safe to use. The experiment focused on the analysis of salivary amylase using starch from food as a substrate, black tea as an inhibitor,…

This three-part laboratory experiment investigates key aspects of the Buchwald-Hartwig amination cross-coupling reaction through guided-inquiry learning strategies. The first part of this experiment utilizes high-throughput experimentation techniques to reinforce, explore, and extend fundamental concepts that are represented in the classroom,…

A traditional laboratory course with the primary learning outcome of improving students' theoretical knowledge has received much criticism over the years due to the lack of evidence that these goals have achieved. We report our efforts to redesign a traditional first-year organic and inorganic (also known as synthetic) laboratory course from…

The Making Introductory Courses Real while Online (MICRO) laboratory project was developed to meet the need for hands-on experiments, focused on topics in analytical chemistry, to be delivered safely remotely or in a socially distanced in-person lab. Unlike more traditional lab experiments, MICRO laboratories use only microgram or nanogram amounts…

Contribution: This article proposes a low-cost and mobile device-based learning support system for the stepper motor, which provides Web-based remote laboratory. This system allows young engineers to learn about rotational principles, control methods, and programming in stepper motors. Background: Familiarity with electrical machinery, such as…

Optimal integration of education and ongoing faculty research in many undergraduate science programs is limited to the capstone project. Here, we aimed to develop a novel course-based undergraduate research experience (CURE) in synergy with ongoing faculty research. This 10-week course called Biomedical Research Lab is embedded in the curriculum…

DNA structure has been leveraged in a variety of facets that allow scientists to perform a range of assays, including ones for identification of species, establishing evolutionary relationships between taxa, or even identifying individuals. Here, we present a DNA barcoding method as practical, hands-on approach that connects several experimental…

Solid lipid nanoparticles (SLNs) are exciting nanoparticles used for transporting therapeutic drugs into an organism. In this laboratory work, a simple experiment is performed to introduce master's students into the field of nanotechnology, here applied to health including the applications in the healthcare/pharmaceutical and cosmetic industry.…

Infrared (IR) spectroscopy is a vibrational spectroscopic technique useful in chemical, pharmaceutical, and forensic sciences. It is essential to identify chemicals for reasons spanning from scientific research and academic practices to quality control in companies. However, in some university degrees, graduate students do not get the proficiency…

In this laboratory experiment, students evaluated three silver(I) complexes as potential additives for dental adhesives based on bacterial growth inhibition, heat stability, water insolubility, and cost-effectiveness. Each student prepared and analyzed a cyanoxime ligand and its corresponding silver(I) complex. Students characterized the…

In this laboratory experiment, students explore the aquatic photochemical fate of ranitidine and cimetidine, two common pharmaceutical pollutants found in wastewater. It provides an engaging environmental context for students to develop knowledge of reaction kinetics and photochemistry as well as skill in using analytical instrumentation. This…

Patch-clamp electrophysiological recordings of neuronal activity require a large amount of space and equipment. The technique is difficult to master and not conducive to demonstration to more than a few medical students. Therefore, neurophysiological education is mostly limited to classroom-based pedagogies such as lectures. However, the…

In this study, it is aimed to develop practical teaching activities that can be used in optics teaching. For this purpose, a virtual laboratory environment was created in RayLab which is an application for design and simulation of optics on the iPad/iPhone. In this context, the dispersion of white light in the prism, the relationship between the…

In this paper, we present a selection methodology in the physics laboratory that lowers student anxiety and is beneficial to the instructors as well. At Mount Royal University, the traditional laboratory experimental exercises were replaced by a new style of laboratory called labatorials. In our previous research work, we found that labatorials…

General education science courses at a Canadian postsecondary institution implemented "Beyond Labz" virtual science labs. Faculty members teaching vocational science-related courses tested this resource. This qualitative study explores faculty member and learner perceptions of the efficacy of these virtual labs in terms of ease of use,…
