Laboratory safety regulations have been traditionally viewed by its learners and practitioners as a matter of law and policy, which simply requires compliance. A compliance mindset tends be passive and dissociates individuals (or even institutions) from the important reasons and principles underlying the safety rules and regulations, leading to…

Ângelo Luís; Fernanda Domingues – Biochemistry and Molecular Biology Education, 2025
Bacteria have developed a cell-to-cell communication system called quorum sensing (QS), allowing them to regulate group behavior and synchronize the expression of virulence factors, responsible for increasing their infection capacity and resistance to antimicrobials. Although the control of microbial infections through the inhibition of microbial…

Owing to the critical role of stereochemistry in biotechnology, medicine, and industry, it must be well represented in undergraduate lab curricula. To achieve these stereochemical laboratory requirements without sacrificing existing lab techniques, we modified two standard laboratory experiments to include chiral GC analysis as follows. (1) The…

The ability to elucidate the structure of organic compounds from their nuclear magnetic resonance (NMR), infrared (IR), and mass spectrometry (MS) spectra is an essential skill, particularly for those engaged in the fields of synthetic and analytical organic chemistry. Spectral analysis constitutes a fundamental component of the curriculum for all…

T. Leon Venable – Journal of Chemical Education, 2024
As an introduction to quadrupolar effects in NMR spectroscopy, students use low field ([superscript 1]H, 60 MHz), benchtop [superscript 13]C NMR spectroscopy to contrast the spin-spin coupling behavior of [superscript 13]C to the dipolar [superscript 1]H and quadrupolar [superscript 2]D in familiar solvents C(H/D)Cl[subscript 3], C(H/D)[subscript…

An effective, practical approach for incorporating molecular biology tools to biology and biochemistry students is described. For 6 weeks, students are exposed to bacterial transformation, plasmid DNA purification and analysis, parasite transfection, ectopic expression of fluorescent proteins, fluorescence microscopy, and flow cytometry analysis.…

The American Chemical Society advocates a shift from rule-based to risk-based safety education for chemistry graduates, emphasizing meaningful student engagement in the risk assessment process for laboratory work. To implement this paradigm shift, we introduced RAMP (Recognize Hazards, Assess Risk, Minimize Risk, and Prevent Emergencies)-based…

Research exploring the advantages and limitations of different laboratory modes on student learning is critical so that engineering instructors can design hybrid/blended laboratories to maximise student learning. However, limited research explores the impact of take-home laboratories on student learning. This article documents the impact that the…

Angela S. Kelling; Nicholas J. Kelling – Teaching of Psychology, 2025
Background: Given the increased emphasis on active learning in psychology, it is important to use data to enhance these experiences. In learning courses, both live animals and virtual training laboratories have been found to enhance learning, but less research has examined student preferences. Generally, live rats are preferred, but students may…

Fluorescence-related experimental techniques play an important role in biochemistry, molecular biology, and cell biology. However, fluorescence-related experiments are rarely included in the laboratory courses of most Chinese universities. This is mainly due to the conflict between large class size (50-60 students in one room) and funding/space…

By hosting a college students' laboratory skills contest, we provide an interesting activity for students to cultivate good laboratory practices and thereby improve their laboratory skills. The substance of this contest is the detection of the hardness of water, which involves numerous laboratory skills such as solution preparation, weight by…

A. C. Cooper; J. B. Osness; S. D. Hester; M. S. Bolger – CBE - Life Sciences Education, 2024
Undergraduate laboratory courses can provide opportunities for students to participate in science practices. This requires rethinking both curricula and instruction. Science practice--based courses require students to be positioned as epistemic agents, implying a shift in instructor role. Teaching assistants (TAs) are the primary instructors for…

Simbarashe Nkomo; Alia Bly – Journal of Chemical Education, 2024
In undergraduate science education, laboratory courses stand as essential cornerstones of experiential learning. Chemistry laboratory courses offer students unique hands-on experiences that bridge the gap between theoretical knowledge and practical application. The journey through the undergraduate chemistry curriculum is paved with a series of…

Physiology is an important field for students to gain a better understanding of biological mechanisms. Yet, many students often find it difficult to learn from lectures, resulting in poor retention. Here, we utilize a learning workshop model to teach students at different levels ranging from middle school to undergraduate. We specifically designed…
