Laboratory research experiences can be an important part of the training process for STEM professionals, but barriers exist that can prevent broad access to these opportunities. Virtual Research Group (VRG) modules, which use data curated from the scientific literature to simulate aspects of the research process, provide a scalable alternative to…

Since the appearance of the COVID-19 pandemic and its subsequent stage, the changes produced in the chemistry teaching process have allowed educators to use a wide range of strategies, methodologies, and tools to promote student learning. To carry out laboratory practices, some strategies reported include the use of simulators and educational…

This research aims to examine the effect of integrating arts in a laboratory practice, concerning basic artistic stage, chemistry and art, dermocosmetics, and laboratory practice level dermocosmetics production, on the learning performance of students. The application process consisted of two stages, namely an experimental stage and an artistic…

A pedagogically useful undergraduate organic-chemistry-laboratory experiment has been developed that involves the synthesis of two structurally simple, achiral "O,O"- and "N,N"-acetal substrates with no stereocenters. The experiment introduces students to a "new" and more effective variant of classical acetal…

A new experiment for use in introductory nanotechnology courses is described. This experiment allows students to fabricate metallic wires with microscale lateral dimensions and nanoscale vertical dimensions. Fabrication occurs in the capillaries of polydimethylsiloxane (PDMS) stamps modified with hydrophilic polymers. This experiment provides…

Purpose: This study aims to investigate patterns of information use among undergraduate engineers as they progress through their academic programs. The primary objective was to discern how second and fourth-year students differ in their use of different types of information while performing specific tasks, namely, conducting labs, composing…

Coronavirus (COVID-19) disease is an emerging situation that brought challenges to all sectors, including academia and research. Undergraduate and postgraduate students in biochemistry and molecular biology have been affected significantly due to the recent laboratory closures. Experiments have been suspended for long causing extreme stress to the…

This article describes a straightforward approach to deliver an enzyme assay and kinetics laboratory via online delivery methods in the time of COVID-19.

Single-crystal X-ray structures, melting points, and students' specific rotation results on carvone semicarbazone derivatives are presented with experimental details. Critical parameters are identified to ensure the success of the experiment. Procedures developed here were tested in a laboratory course, consisting of approximately 70 students over…

We report a research-enhanced undergraduate laboratory practical in which students synthesize and characterize color-controllable, stable silver nanoparticles for use in a simple catalytic reaction analyzed by UV-vis spectroscopy. The practical has been prepared for students using electronic laboratory notebooks, enables collaborative data…

A new two-step experiment has been designed and developed for the curriculum of the Organic Chemistry Laboratory 2 (CHEM2240L) sophomore course at Xavier University of Louisiana, in New Orleans. Initially, cyclohexanol was converted to cyclohexanone using bleach as the oxidizing agent followed by the formation of the cyclohexanone oxime. However,…

Nuclear magnetic resonance (NMR) spectroscopy is an indispensable technique in the organic chemistry laboratory for elucidation of molecular structure. Miniaturization of NMR technology has attracted attention and acceptance due to a considerable reduction in the cost to acquire and maintain the instrument. The advent of low-field, low-cost, and…

This research aims to develop an ocean wave energy converter kit from low-cost materials as a teaching tool. The kit is developed using the working principle of a wave energy converter that uses a buoy as a system drive and a weight balancer that is connected to a chain. The dimensions of the kit are 6.7 × 0.3 × 0.4 m (length × width × height)…

In this paper, we describe a study of cosmic ray muon rates and energies at various elevations on Mauna Kea on the island of Hawaii. The study was originally conceived as an extension to the upper-division modern physics laboratory at the University of Hawaii at Hilo and used the TeachSpin Muon Physics apparatus (abbreviated TSMP below) from that…

Progress is made in science by constructing many models (possibly of different complexities), testing them against measurements, and determining which of them explain the data the best. It is my observation, however, that in many introductory physics labs we provide students with the materials and methods to verify the "correct" model of…
