Anoshia Khan; Cristina Altamirano; Yousuf Khan; Haroon Saeed; Tyler Moreira; Troy T. Handlovic; Mohammed R. Elshaer; Justin A. Bogart – Journal of Chemical Education, 2023
Many of the current synthetic methodologies utilized within academic and industrial laboratories require knowledge of how to safely handle air- and moisture-sensitive reagents and work under inert atmospheres. As a result, the ACS Committee on Professional Training recommends incorporating synthetic methods that make use of these inert atmospheres…

Gibbons, Jessica A.; Garcia, Reynaldo L.; Craig, Paul A.; Yu, Gracia Fe B.; Macaulay, Janet O. – Biochemistry and Molecular Biology Education, 2020
Laboratory classes are a central element of all biochemistry and molecular biology programs. These play a role in developing students' hands-on and technical skills and also offer much more. The design of laboratory classes depends on many factors including the programs the students are enrolled in, the level they are at, employment destinations,…

Mei Zhang; Wangmin Hu; Wenjing Liu; Chang Lei; Jun Guo; Hongcai Shang; Junling Hou – Journal of Chemical Education, 2022
Interdisciplinary experiments within chemistry are very important for the improvements in the overall quality of the education received by students. In this work, we describe an interdisciplinary experiment that was successfully completed by undergraduate students. This training integrates multiple disciplines including natural product medicinal…

Triboluminescence is a fascinating phenomenon that can engage students' interest in chemistry. However, safe, cost-effective, and accessible laboratory experiments featuring highly triboluminescent substances are limited. To bridge this gap, we present a simple, rapid, semimicro test tube preparation of the visually engaging manganese complex…

Kearns, James K.; van der Wielen, Matthew – Journal of Chemical Education, 2021
By focusing on food and a pervasive contaminant, this experiment engages student interest and effort while providing essential instruction and experience. As institutions are challenged by existing and emerging budgetary constraints, this experiment offers a determination approach employing commonly available instrumentation, the graphite furnace…

Alexander Grushow – Journal of Chemical Education, 2022
A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students' connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto-enol tautomerization of 2,4-pentanedione. However, unlike…

Bopegedera, A. M. R. P.; Coughenour, Christopher L. – Journal of Chemical Education, 2021
A new project-based laboratory (PJBL) was developed for general chemistry students to tackle the steps involved in chemical water quality analysis using an accessible, real-world hydrologic system (the lakes of the Lower Grand Coulee, Washington). This PJBL was developed in a joint general chemistry and environmental geology course by a…

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.…

Niu Huang; Chao Li; Shili Gan; Cancan Le; Huan Liu; Wei Liu; Liqun Ye – Journal of Chemical Education, 2022
With the benefits of low cost, energy efficiency, and environmental protection, photocatalytic hydrogen production is considered to be the most promising technology for the development of a clean and sustainable society. However, the utilization of photocatalytically generated hydrogen is not very common yet. Therefore, tertiary education urgently…

Vlaardingerbroek, Barend – School Science Review, 2018
The role of the school science laboratory, once taken for granted as verification of taught theory using prescribed ('cookbook' to critics) practical activities, has become less clear since the emergence of the 'inquiry' paradigm in which the school laboratory would appear to become a make-believe science research laboratory. But a school science…

Harwood, Cynthia J.; Hewett, Sarah; Towns, Marcy H. – Journal of Chemical Education, 2020
This communicaton shares with the chemistry education community the rubrics used to evaluate student videos associated with using a pipet, using a buret, and making a solution in a volumetric flask that were part of a digital badging project. The rubrics were used across multiple general chemistry courses, hundreds of teaching assistants, and…

Hammerstad, Marta; Røhr, Åsmund K.; Hersleth, Hans-Petter – Biochemistry and Molecular Biology Education, 2019
Many laboratory courses consist of short and seemingly unconnected individual laboratory exercises. To increase the course consistency, relevance, and student engagement, we have developed a research-inspired and project-based module, "From Gene to Structure and Function". This 2.5-week full-day biochemistry and structural biology module…

Kylie L. Luska – Journal of Chemical Education, 2022
A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

Seery, Michael K.; Jones, Ariana B.; Kew, Will; Mein, Thomas – Journal of Chemical Education, 2019
Experimental design is a desirable outcome of laboratory education. Incorporating inquiry into the laboratory curriculum is attractive, but there are acknowledged concerns from practical, theoretical, and epistemological perspectives, and these are accentuated in upper-division courses. In this work, we draw on the extensive literature relating to…

Kocemba-Pilarczyk, Kinga A.; Ostrowska, Barbara; Dudzik, Paulina; Markiewicz, Michal J.; Sotirios Souza Pegos, Débora; Lim, Chaewon – Biochemistry and Molecular Biology Education, 2019
Diagnostic molecular biology is a fast developing discipline of laboratory medicine widely used in numerous medical branches such as oncology, hematology, immunology, internal medicine, or infectious diseases, which will certainly have a major impact on clinical medicine in the near future. Nowadays, educational process is forced to face the…
