Understanding potentiometry is a difficult task when students in initial courses of Analytical Chemistry are first introduced to instrumental techniques. The closest instrument to them is a pH meter, which is frequently used as a "black box", without a real understanding of how it works. Here we present the assembly of jelly modules that…

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…

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…

The COVID-19 pandemic has significantly affected teaching processes worldwide, particularly in laboratory-intensive courses. To adapt, online experiments have been implemented globally. In response, educators at the Department of Chemistry, Chulalongkorn University, developed a Lab@Home chemistry experiment for their general chemistry lab course…

An inquiry-based learning approach was implemented into comprehensive organic chemistry experiments focusing on the formation process of N-phenylbenzamide from the reaction between N-benzylideneaniline and benzoyl peroxide in commercial dimethyl sulfoxide. Students conducted comparative experiments using alternative reagents or reaction conditions…

Hydrogen is a sustainable and climate-friendly storage for renewable energies and can directly be generated from sunlight, e.g., by photocatalytic water splitting. This article presents the photocatalytic hydrogen evolution using LED irradiation of an aqueous ZnS particle dispersion with Na[subscript 2]S and Na[subscript 2]SO[subscript 3] as…

Affect and emotions matter to science learning. They also matter because they are integral to science identity formation and sense of belonging. This study aims to foreground the epistemic and affective character of laboratory work in higher science education by conceptualizing it as epistemic practice, in which students activate their body and…

Prendergast, Aisling M.; Shanahan, Rachel; Hickey, Aobha; Harrington, Francis; Schönbauer, David; Byrne, Peter A.; Schnürch, Michael; McGlacken, Gerard P. – Journal of Chemical Education, 2020
In the past decade, C-H functionalization has been a very active topic of research in both academia and industry. When a H atom is replaced by an aryl (or heteroaryl) group, the transformation is termed "direct arylation". This approach to the formation of key (hetero)aryl-(hetero)aryl bonds is complementary to traditional methods, such…

Duerden, Amanda; Moon, Nicole; Grubbs, G. S., II – Journal of Chemical Education, 2021
Few laboratory exercises exist that introduce undergraduate students to both the concepts and instrumentation used in rotational spectroscopy. Because of this gap in undergraduate laboratory training, a teaching laboratory for the pure rotational spectroscopy of benzonitrile has been developed and reported. Owing to benzonitrile's recent discovery…

Goeltz, John C.; Cuevas, Lia A. – Journal of Chemical Education, 2021
Acid-base titration laboratories are perennially offered to general chemistry students in preparation for summative assessments of their hands-on and quantitative skills in the field. Here, we present a guided inquiry-based activity focused on total titratable acidity (TTA) as alternative to standard "cookbook" titration laboratory work.…

Cullinane, Dearbhla P.; Barry, Denis S. – Anatomical Sciences Education, 2023
Prior to the challenges imposed by the COVID-19 pandemic, anatomy practical sessions at Trinity College Dublin involved eight to 10 students per donor station, rotating between digital learning, anatomical models/osteology, and dissection activities for three hours weekly. To maintain cadaveric participation in the anatomy laboratory while…
