Tracy M. Mattox; Anne L. Pham; Michael D. Connolly; Liana M. Klivansky; Rohan Dhall; Jeffrey J. Urban – Journal of Chemical Education, 2023
Laboratory chemical synthesis research typically lacks the preplanned hazard responses found in production-scale industrial laboratories. Chemical safety management is a known challenge in education-based facilities, which is concerning for academic and national laboratory environments working with inexperienced student researchers. At the…

Shuang Qiu; Dongyang Zhang; Vishal Yeddu; Cristina Cordoba; Arthur M. Blackburn; Violeta Iosub; Makhsud I. Saidaminov – Journal of Chemical Education, 2023
When structure-property relationships are discussed in inorganic chemistry and materials science, the common perception is that materials with the same composition and atomic arrangement have the same properties. In this laboratory experiment, we show that "processing"--the exact conditions under which materials are made--can in fact…

Salvador Gallegos-Martínez; Kristen Aideé Pérez-Alvarez; Grissel Trujillo-de Santiago; Mario Moisés Alvarez – Biomedical Engineering Education, 2025
Purpose: Hands-on training in tissue engineering is often associated with specialized labs and expensive equipment, such as CO[subscript 2] incubators. To minimize the use of costly commercial incubators and provide a more vivid engineering experience in a biology lab, we present a hands-on project that introduces medium to large groups of…

Liying Zhu; Daner Sun; Ma Luo; Weidong Liu; Song Xue – Journal of Science Education and Technology, 2024
The laboratory plays a crucial role in science education. However, teacher education for pre-service teachers' design performance in the laboratory is still challenging. This study paved the way for redesigning traditional laboratory teaching into a student-centered approach: inquiry-based design thinking (IBDT). To investigate the impact of the…

Leonardo Antonelli; Rosiene Reis Mattos; Mauricio Moraes Victor; Silvio Cunha – Journal of Chemical Education, 2024
A multicomponent reaction was adapted and successfully applied in the major organic course, which involves synthesizing and characterizing a 1,3-benzoxazine derived from paracetamol extracted from tablets of the worldwide well-known medicine Tylenol. Using paracetamol as a reagent is a motivational strategy in undergraduate laboratories to meet…

Tamara Belen Palermo; Lorena Del Rosario Cappellari; Julieta Chiappero; Romina Del Valle Meneguzzi; Samanta Gil; Walter Giordano; Erika Banchio – Journal of Biological Education, 2024
Despite the growing awareness of the importance of plant secondary metabolites in insect-plant interactions, undergraduate degree content in agronomy and biology generally does not provide a clear concept to students in relation to secondary metabolite induction of plant defences, implying that students do not obtain a good understanding of the…

Mahaveer Genwa; Jyoti Singh; Alka Rani; Kushagra Yadav; Chetna Angrish – Journal of Chemical Education, 2024
Photochemical reactions are initiated by the absorption of light, triggering the chemical reactions and resulting in the formation of products. These reactions are generally performed using a freely available renewable source of energy-solar energy. Solar simulators mimic both the ultraviolet and visible regions of sunlight and hence can serve as…

Aaron Y. Zhao; Nathan E. DeSousa; Hanne C. Henriksen; Ann Marie May; Xianming Tan; David S. Lawrence – Journal of Chemical Education, 2024
A survey was developed and implemented to determine how pervasively safety principles and cultural expectations are included in the chemistry curriculum at the undergraduate level. The survey was completed by first-year doctoral candidates in the chemical/pharmaceutical sciences. A majority of the respondents were trained in the use of Safety Data…

Andrea D. Merry; John A. Means; Tim E. Hall – Journal of Chemical Education, 2024
In this laboratory activity, students were tasked with determining the heat of combustion for each of three common sugar substitutes: saccharin, aspartame, and sucralose. The heats of combustion were determined via three different methods: bomb calorimetry, heats of formation derived from semiempirical calculations, and tabulated average bond…

Joana F. C. Silva; Ma´rio T. S. Rosado; Teresa M. R. Maria; Pedro S. Pereira Silva; Manuela Ramos Silva; M. Ermelinda S. Euse´bio – Journal of Chemical Education, 2023
The concept of co-amorphous systems is introduced in an integrated laboratory experiment, designed for advanced chemistry students, using solvent-free, environmentally friendly mechanochemistry. The dual-drug naproxen-cimetidine co-amorphous system (NPX-CIM) is investigated as an example of the emergent field of medicinal mechanochemistry.…

Jichao Xue; Jiaxin Liu; Qingshu Yuan; Zhengwei Yao; Jin Xu; Zhigeng Pan – Education and Information Technologies, 2025
To optimize learning experience and improve learning performance, current virtual experimental systems usually assist students with stepwise guidance before operations and feedback after them. However, stepwise and excessive guidance can lead to student overreliance, while late feedback cannot avoid potential errors during experimental learning.…

Riccardi, P.; Prete, G.; Chiappetta, F.; Meringolo, C. – Physics Education, 2023
This work discusses a didactic path aimed at revisiting the first experiments on the transmission and detection of electromagnetic waves, performed by Guglielmo Marconi at the end of the 19th century. With very simple materials it is possible to set-up apparatus that allow to illustrate practically the simple physical picture of wireless…

Asmus, Stephen E.; Wells, Collin K.; Montalvo, Hanna M. – Biochemistry and Molecular Biology Education, 2023
Heart muscle cells, or cardiomyocytes, exhibit intrinsic contractility in vitro. We found that commercially-available mammalian cardiomyocytes serve as an excellent model system for studying the cytoskeleton and cellular contractility, fundamental topics in undergraduate cell and molecular biology courses. Embryonic rat cardiomyocytes were plated…

Sigurdur Gudni Gunnarsson; So´lru´n Eli´n Freygardsdo´ttir; O´skar Rudolf Kettler; Benjami´n Ragnar Sveinbjo¨rnsson – Journal of Chemical Education, 2023
Laboratory experiments provide training to students in experimental techniques and strengthen the understanding of the theory. Herein, a new introductory experiment for organic chemistry laboratory courses is described where students are trained in washing an unknown neutral organic compound using liquid/liquid extraction, isolating it via…
