Soule`re, Laurent – Journal of Chemical Education, 2021
We report a molecular modeling study for undergraduate students aimed at carrying out an analysis of small molecules using a systematic conformational search with VEGA ZZ, a freely available software program. Conformational analyses were performed using a systematic search based on variations of torsion angles. First, the conformations of n-butane…

Nida, Safwatun; Marsuki, Muhammad Fajar; Eilks, Ingo – Journal of Chemical Education, 2021
This paper presents a case study examining the current controversial issue of palm oil production for manufacturing biodiesel in Indonesia. The study looks at how this issue was used as a context to teach chemistry at the undergraduate level. The lesson unit promotes general educational skills, which students need to develop in order to become…

Houchlei, Samantha K.; Bloch, Rosalyn R.; Cooper, Melanie M. – Journal of Chemical Education, 2021
This study is a follow up to two earlier studies characterizing student real-time use of mechanistic arrows. In these previous studies, students were asked to predict a product by drawing a curved arrow mechanism using an interface that allowed recording and replay of student actions. In the present study two different student cohorts responded to…

Parobek, Alexander P.; Chaffin, Patrick M.; Towns, Marcy H. – Chemistry Education Research and Practice, 2021
Reaction coordinate diagrams (RCDs) are chemical representations widely employed to visualize the thermodynamic and kinetic parameters associated with reactions. Previous research has demonstrated a host of misconceptions students adopt when interpreting the perceived information encoded in RCDs. This qualitative research study explores how…

Spitha, Natalia; Doolittle, Pamela S.; Buchberger, Amanda R.; Pazicni, Samuel – Journal of Chemical Education, 2021
The Beer-Lambert law is a core spectroscopic relationship widely used across the undergraduate chemistry curriculum and beyond. The derivation of this model is a common topic for upper-level chemistry courses. But, due to its abstract nature, this derivation can often seem like a mathematical exercise detached from the molecular origins of…

Roberts, Charis A.; Allen, Seth; Helmy, Sameh – Journal of Chemical Education, 2021
There has been dramatic growth in interest and research regarding organic photochromism in recent decades. Despite this, the topic is seldom addressed in the undergraduate chemistry curriculum. Herein, we present a straightforward and robust experiment for the second semester organic chemistry laboratory curriculum which combines multistep…

Medel-Esquivel, Ricardo; Gómez-Vargas, Isidro; García-Salcedo, Ricardo; Vázquez, J. Alberto – Physics Teacher, 2021
One of the main topics of elementary physics is the idea that every material is composed of "little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one other." These particles could be atoms or molecules. Atoms are the smallest part into…

Riley, Kasandra J.; Vardar-Ulu, Didem; Pollock, Elizabeth; Dutta, Shuchismita – Biochemistry and Molecular Biology Education, 2021
Understanding the relationship between protein structure and function is a core-learning goal in biochemistry. Students often struggle to visualize proteins as three-dimensional objects that interact with other molecules to affect its biochemical consequences. We describe here a partial course-based undergraduate research experiences that has…

García-Ponce, Ángel Luis; Martínez-Poveda, Beatriz; Blanco-López, Ángel; Quesada, Ana R.; Suárez, Fernanda; Alonso-Carrión, Francisco José; Medina, Miguel Ángel – Biochemistry and Molecular Biology Education, 2021
Metabolism and its regulation is one of the most complex and difficult topics for students learning biochemistry. A problem-/case-based learning (PBL) approach can be useful to help biochemistry students to fulfill the goal of acquiring an integrated view of metabolism and its regulation. The present article describes our experience enrolling…

González-Flores, Diego; Fernández, Gabriela; Urcuyo, Roberto – Journal of Chemical Education, 2021
Electrochemical and spectroelectrochemical techniques are very important for characterizing energy materials. In the search for new sources of renewable energy, water splitting for hydrogen production and CO[subscript 2] reduction is attracting significant attention. These applications require efficient and durable catalysts and a detailed…

Barceló-Oliver, Miquel; Cabello, Carlos P.; Torrens-Serra, Joan; Miró, Manuel; Cabot, Catalina; Bosch, Rafael; Delgado, Montserrat R. – Journal of Chemical Education, 2021
Although residues and resource shortages are major problems of modern living, these topics are not usually properly covered in university curricula. To tackle this situation, we have guided undergraduate students through the design of a group of active learning activities, to demonstrate the science behind separation and recycling: trash…

Van Ryswyk, Hal; Loar, Aech; Kelber, Jacob; Meznarich, Zooey; Sabin, Jocelyn; Griffith, Simone; Stevenson, Leah E. – Journal of Chemical Education, 2021
Tungsten oxide semiconductors are used to photooxidize water. Students prepare WO3, CuWO4, and mixed composition thin film photoanodes. The syntheses are simple, allowing for the quick production of a range of materials. Photoanodes are tested in a photoelectrochemical cell assembled from common equipment, allowing for the direct comparison of…

Li, Zhuoxuan; Yuan, Ling; Liu, Mengfei; Cheng, Zhenfang; Zheng, Juhua; Epstein, Irving R.; Gao, Qingyu – Journal of Chemical Education, 2021
The Briggs-Rauscher reaction is a popular demonstration to illustrate chemical oscillations in laboratories, classrooms, and public seminars because of its simplicity and visual appeal. Here, we adapt the Briggs-Rauscher reaction to present reaction-diffusion-convection patterns in the undergraduate general or physical chemistry laboratory. By…

Pinochet, Jorge – Physics Education, 2019
Given the great interest that black holes arouse among non-specialists, it is important to analyse misconceptions related to them. According to the author, the most common misconceptions are that: (1) black holes are formed from stellar collapse; (2) they are very massive; (3) they are very dense; (4) their gravity absorbs everything; and (5) they…

Kayla Vieno-Corbett; Nicole Campbell; Angela Pecyna; Kem A. Rogers – Anatomical Sciences Education, 2025
Gross anatomy is often taught and assessed based on a "standard" view of the human body, limiting students' exposure to normal variation, creating a potential curricular gap in the training of future anatomists and health care professionals. This scoping review explores learning objectives and teaching approaches associated with…
