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…

Yeo, Brandon Pei Hui; Foong, Lian Chee; Tam, Sheh May; Lee, Vivian; Hwang, Siaw San – Biochemistry and Molecular Biology Education, 2018
Structures and functions of protein motifs are widely included in many biology-based course syllabi. However, little emphasis is placed to link this knowledge to applications in biotechnology to enhance the learning experience. Here, the conserved motifs of nucleotide binding site-leucine rich repeats (NBS-LRR) proteins, successfully used for the…

Manneh, Ilana L.; Hamza, Karim M.; Rundgren, Carl-Johan; Eriksson, Lars – Asia-Pacific Forum on Science Learning and Teaching, 2018
Anthropomorphisms are widespread at all levels of the educational system even among science experts. This has led to a shift in how anthropomorphisms are viewed in science education, from a discussion of whether they should be allowed or avoided towards an interest in their role in supporting students' understanding of science. In this study we…

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…

Hensen, Cory; Clare, Tami Lasseter; Barbera, Jack – Journal of Chemical Education, 2018
Fluorescence spectroscopy experiments are a frequently taught as part of upper-division teaching laboratories. To expose undergraduate students to an applied fluorescence technique, a corrosion detection method, using quenching, was adapted from authentic research for an instrumental analysis laboratory. In the experiment, students acquire…

Pagano, Justin K.; Jaworski, Leslie; Lopatto, David; Waterman, Rory – Journal of Chemical Education, 2018
A research-based inorganic chemistry laboratory course is described. Using the defined protocol of a course-based undergraduate research experience (CURE), students undertake a self-designed research project to identify new catalysts for the dehydrogenation of ammonia borane. Students select ligands and metals, prepare and characterize catalysts…

Brom, Joseph M. – Journal of Chemical Education, 2018
Molecular orbital configurations give rise to electronic terms comprising corresponding electronic states. Electronic terms possess symmetry classifications, which are denoted by a term symbol, based on the symmetry properties of the electronic wave functions associated with the states. Using the methylene radical, and both planar and twisted…

Sanders, Wesley C.; Valcarce, Ron; Iles, Peter; Smith, James S.; Glass, Gabe; Gomez, Jesus; Johnson, Glen; Johnston, Dan; Morham, Maclaine; Befus, Elliot; Oz, Aimee; Tomaraei, Mohammad – Journal of Chemical Education, 2017
This manuscript describes a laboratory experiment that provides students with an opportunity to create conductive silver nanogrids using polymeric templates. A microcontact-printed polyvinylpyrrolidone grid directs the citrate-induced reduction of silver ions for the fabrication of silver nanogrids on glass substrates. In addition to…

Lipchock, James M.; Ginther, Patrick S.; Douglas, Bonnie B.; Bird, Kelly E.; Loria, J. Patrick – Biochemistry and Molecular Biology Education, 2017
Here, we present a 10-week project-oriented laboratory module designed to provide a course-based undergraduate research experience in biochemistry that emphasizes the importance of biomolecular structure and dynamics in enzyme function. This module explores the impact of mutagenesis on an important active site loop for a biomedically-relevant…

Le, Christine M.; Morra, Barbora – Journal of Chemical Education, 2019
The tutorials of a second-year undergraduate organic chemistry course have been modified to include a retrosynthetic exercise in conjunction with a Molecule of the Week (MoW) challenge. In contrast to the original tutorial assignments in the course, which primarily focused on completing simple reaction roadmaps, the new tutorials place a heavier…

Odom, Arthur L.; Bell, Clare V. – Science Teacher, 2019
In 1827, Robert Brown noticed pollen suspended in water bouncing around erratically. It wasn't until 1905 that Albert Einstein provided an acceptable explanation of the phenomenon (Kac 1947): Brownian motion is the random movement of particles (e.g., pollen) in a fluid (liquid or gas) as a result of collisions with atoms and molecules. Movement of…

Düsing, Katharina; Asshoff, Roman; Hammann, Marcus – Journal of Biological Education, 2019
This study investigates students' conceptions of the carbon cycle with regard to the components they believe to be relevant to the carbon cycle, how they interrelate these components, the ways in which they trace carbon atoms, and the different levels of biological organisation they consider when doing so. A total of 142 students aged 13-16 years…

Huang, Tzu-Yang; Ku, Chih-Hsiung – International Baltic Symposium on Science and Technology Education, 2019
The purpose of the research was to understand the public's social Image of emerging technology-- nanotechnology. Furthermore, the differences among different major students and the decision-making style in "self-evaluation and other-evaluation" were analyzed too. In this research, the social image was defined by three phases,…

Dragojlovic, Veljko – Journal of Chemical Education, 2015
Preparation of an inexpensive model set from whiteboard markers and either HGS molecular model set or atoms made of wood is described. The model set is relatively easy to prepare and is sufficiently large to be suitable as an instructor set for use in lectures.

Hanukoglu, Israel – Biochemistry and Molecular Biology Education, 2015
The Rossmann fold is one of the most common and widely distributed super-secondary structures. It is composed of a series of alternating beta strand (ß) and alpha helical (a) segments wherein the ß-strands are hydrogen bonded forming a ß-sheet. The initial beta-alpha-beta (ßaß) fold is the most conserved segment of Rossmann folds. As this segment…
