Elisabeth Baland; Lucía Pérez Jimenez; André Mateus – Biochemistry and Molecular Biology Education, 2025
The function of proteins is governed by their three-dimensional structure. This structure is determined by the chemical characteristics and atomic interactions of amino acids. Students of biochemistry, with a particular focus on protein chemistry, benefit from looking at protein structures and understanding how proteins are built and fold. Due to…

Karaismailoglu, Fatma; Yildirim, Mehtap – Biochemistry and Molecular Biology Education, 2023
This article presents the integration of Tinkercad, a free online modeling program that allows students to model molecular genetic concepts, into the distance learning process. The students had the opportunity to learn molecular genetics in a fun and more efficient way in spite of the limitations of the COVID-19 lockdown, and, in this respect, it…

Dias, Lucas A. L.; Faria, Roberto B. – Journal of Chemical Education, 2020
The use of symmetry is widespread in chemistry, as it is used for predictions of the number of allowed and forbidden absorptions in electronic, vibrational, and rotational spectroscopies; for predictions of the combination of atomic orbitals to produce molecular orbitals; and in many other chemical applications. One critical step in these…

Mahaffey, Angela L. – Journal of Chemical Education, 2019
In both 2016 and 2019, the NCLEX-RN (National Council Licensure Examination -- RN computerized exam) test plan outlined 15% of content as "pharmacological and parenteral therapies". The test plan also includes physiological sciences. The topics of pharmacology encompass the review of drug action in living organisms, such as humans. As…

Wright, Lyniesha; Oliver-Hoyo, Maria – Journal of Chemical Education, 2021
An augmented reality (AR) application and an activity worksheet have been developed to support students in visualizing the concepts involved when solving [superscript 1]H NMR problems. This instructional resource was designed to encourage conceptual problem-solving and prevent memorization by eliminating the use of chemical shift tables. It uses…

Celik, Harun; Kirindi, Talip; Aycicek Kotaman, Yasemin – Journal of Turkish Science Education, 2020
The aim of this study is to examine the effects of computer-based analogy (CBA) used in science teaching in terms of the unit of Structure and Properties of Matter on seventh-grade students' academic success. The attitudes of students against science teaching lesson were also described in this study. This study was applied to 60 seventh-grade…

Primo, Emiliano D.; Otero, Lisandro H.; Ruiz, Francisco; Klinke, Sebastián; Giordano, Walter – Biochemistry and Molecular Biology Education, 2018
The bacterial cell wall, a structural unit of peptidoglycan polymer comprised of glycan strands consisting of a repeating disaccharide motif [N-acetylglucosamine (NAG) and N-acetylmuramylpentapeptide (NAM pentapeptide)], encases bacteria and provides structural integrity and protection. Lysozymes are enzymes that break down the bacterial cell wall…

Zdanovskaia, Maria A.; Schwarz, Cara E.; Habib, Asif D.; Hill, Nicholas J.; Esselman, Brian J. – Journal of Chemical Education, 2018
The use of computational molecular modeling to enhance the teaching of chemical concepts is becoming commonplace. Incorporation of this technique into the curriculum, however, typically requires financial investment. This reality poses a problem for institutions where funding and associated resources are scarce and has a potential negative impact…

Avery, Patrick; Ludoweig, Herbert; Autschbach, Jochen; Zurek, Eva – Journal of Chemical Education, 2018
The "Yet Another extended Hu¨ckel Molecular Orbital Package" (YAeHMOP) has been merged with the Avogadro open-source molecular editor and visualizer. It is now possible to perform YAeHMOP calculations directly from the Avogadro graphical user interface for materials that are periodic in one, two, or three dimensions, and to visualize…

Sun, Ji-Zheng; Tang, Yu-Jing; Sa, Rong-Bo; Gao, Yan-Xia – Journal of Chemical Education, 2019
A bioinformatics laboratory experiment was designed to help undergraduate students learn RNA structure and function in biochemistry courses. In this laboratory experiment, students used 5S rRNAs as material to predict secondary structure and visualize three-dimensional (3D) structure. Students first downloaded molecular information from the 5S…

Fatemah, Amal; Rasool, Shahzad; Habib, Uzma – Journal of Chemical Education, 2020
Students undertaking courses in the field of chemistry need to integrate their spatial skills and conceptual knowledge. However, model perception along with the understanding of spatial processes and spatial structures of molecules has been a cause of difficulty for students as conventional teaching methods cannot fully aid student comprehension.…

Li, Zhao; Corti, David S. – Journal of Chemical Education, 2018
The application of the Reaction Monte Carlo (RxMC) algorithm to standard textbook problems in chemical reaction equilibria is discussed. The RxMC method is a molecular simulation algorithm for studying the equilibrium properties of reactive systems, and therefore provides the opportunity to develop computer-based "experiments" for the…

Haworth, Naomi L.; Martin, Lisandra L. – Journal of Chemical Education, 2018
A series of computer-based laboratory experiments have been developed to aid undergraduate students in appreciating the three-dimensional nature of chemistry and biochemistry. Both lower- and upper-division experiments have been developed. Students are introduced to the use of ChemDraw for the production of professional-quality molecular…

Abualia, Mohammed; Schroeder, Lianne; Garcia, Megan; Daubenmire, Patrick L.; Wink, Donald J.; Clark, Ginevra A. – Journal of Chemical Education, 2016
An understanding of protein folding relies on a solid foundation of a number of critical chemical concepts, such as molecular structure, intra-/intermolecular interactions, and relating structure to function. Recent reports show that students struggle on all levels to achieve these understandings and use them in meaningful ways. Further, several…

Camrud, Evan; Turner, Daniel B. – Journal of Chemical Education, 2017
Numerous computational and spectroscopic studies have demonstrated the decisive role played by nonadiabatic coupling in photochemical reactions. Nonadiabatic coupling drives photochemistry when potential energy surfaces are nearly degenerate at avoided crossings or truly degenerate at unavoided crossings. The dynamics induced by nonadiabatic…
