Ross, Keith – School Science Review, 2019
This article argues that we need to make use of our everyday experiences when introducing concepts in chemistry that are often obscure. It uses reaction rates as an example and explores a common misconception related to the explanation of the effect of rising temperature on the rate of slow reactions.

Gregory S. Watson; Jolanta A. Watson – Journal of Chemical Education, 2023
With many universities now admitting students into their science programs with little or no prior knowledge of the relevant field, significant challenges arise in the way these fields are introduced. Challenges mount with various preconceived ideas regarding the levels of difficulty, thus necessitating introductory concepts be presented in…

Chowdhury, Pinaki – Online Submission, 2022
Development of cognitive skills is critical for developing the right conceptual ideas in chemistry. Atomic structure, bonding, and associated properties are taught as parts of high school chemistry courses worldwide. The cumulative build-up of misconceptions about the periodic table is to blame for students' poor performance on atoms and…

Forbes-Lorman, Robin; Korb, Michele; Moser, Amy; Franzen, Margaret A.; Harris, Michelle A. – Journal of College Science Teaching, 2022
Physical and life science disciplines emphasize how basic structural units influence function, yet it is challenging for students to understand structure-function relationships, particularly at molecular scales. Undergraduates in our biology capstone course struggled to connect mutations in a gene encoding a key protein in a cell development…

Zhao, Yanlu; Lim, Minyoung; Choi, Sungmoon; Yu, Junhua – Journal of Biological Education, 2022
The attractive photophysical properties of luminescent nanoparticles have prompted numerous studies on their synthesis and biological applications. Due to the complexity of components, sizes, morphologies, and strong light scattering of the nanoparticles the absorption spectrum alone is not enough for characterising and analysing the real…

Qianfu Luo; Chenyu Shi; Zhaoxia Wang; Meng Chen; Da-Hui Qu – Journal of Chemical Education, 2022
Given the importance of self-healing polymers for chemistry education, herein, we introduce our latest research results in self-healing materials based on thioctic acid into undergraduate chemistry laboratory. In this experiment, a natural small molecule, thioctic acid (TA), and a few other commercially-available reagents have been used to make a…

Brannon, Jacob P.; Ramirez, Isaac; Williams, DaShawn; Barding, Gregory A., Jr.; Liu, Yan; McCulloch, Kathryn M.; Chandrasekaran, Perumalreddy; Stieber, S. Chantal E. – Journal of Chemical Education, 2020
Experimental methods for determining 3-D atomic structures, such as crystallography, are rarely taught in the undergraduate curriculum, yet are considered to be the norm for 3-D structure determination in a research setting. Although a fully physical understanding of crystallography takes years of practice, practical applications and basic…

Rasmawan, Rahmat – International Journal of Instruction, 2020
The purpose of this research was to develop a multi-representation based e-book on the concept of intermolecular forces that is valid and feasible for use. The form of research used was Research and Development (R&D), which refers to the ADDIE development model consisting of five stages, namely analysis, design, development, implementation and…

Punnoose, Jibin Abraham; Halvorsen, Ken; Chandrasekaran, Arun Richard – Journal of Chemical Education, 2020
There is a disconnect between the cutting-edge research done in academic laboratories, such as nanotechnology, and what is taught in undergraduate laboratories. In the current undergraduate curriculum, very few students get a chance to do hands-on experiments in nanotechnology-related fields, most of which are through selective undergraduate…

Huggins, Michael T.; Kesharwani, Tanay; Buttrick, Jonathan; Nicholson, Christopher – Journal of Chemical Education, 2020
Nuclear magnetic resonance (NMR) spectroscopy has become a cornerstone tool for studying a variety of molecular features in advanced chemistry laboratories. In this experiment, students prepare a pyrrole-[beta]-amide via a one-pot, three-step synthesis and use NMR spectroscopy to confirm its molecular structure. In addition, variable temperature…

Yuan, Min; Sun, Chun-Yan; Liu, Yi-Wei; Lu, Ying; Zhang, Zhong; Li, Xiao-Hui; Tian, Hong-Rui; Zhang, Shan; Liu, Shu-Xia – Journal of Chemical Education, 2020
A research-style laboratory experiment for advanced undergraduate students is described, which includes the synthesis, characterization, and properties (porosity, stability, amphipathy) testing of the composite [Cu[subscript 2](BTC)[subscript 4/3](H[subscript 2]O)[subscript 2][subscript 6][HPW[subscript 12]O[subscript 40]·(C[subscript…

Hanson, Benjamin S.; Brown, Christa P.; Laurent, Harrison; Hughes, Matt D. G.; Dougan, Lorna – Physics Education, 2020
Hierarchical structure and mechanics are crucial in biological systems as they allow for smaller molecules, such as proteins and sugars, to be used in the construction of large scale biological structures exhibiting properties such as structural support functionality. By exploring the fundamental principles of structure and mechanics at the…

Carle, Myriam S.; Flynn, Alison B. – Chemistry Education Research and Practice, 2020
The concept of delocalization (i.e., resonance) is fundamental concept in organic chemistry but essential learning outcomes (LOs) have not previously been proposed nor has there been an analysis of how resonance is taught, despite indications in the literature that students have many non-canonical ideas about the concepts. To address this deficit,…

Patron, Emelie; Linder, Cedric; Wikman, Susanne – Science Education, 2021
Since visual representations play a particularly important role in the teaching and learning of chemistry, the exploration described in this article focuses on them. This is an explorative study of the qualitatively different ways that visual representations can be unpacked by Swedish upper secondary school chemistry teachers dealing with…

Juszczak, Laura J. – Journal of Chemical Education, 2021
One of the more difficult concepts introduced in the first-year undergraduate course, general chemistry, is that of chirality. Typically, left and right hands are the common, macroscopic objects of reference used to demonstrate the quality of being nonsuperimposable, followed by the use of a mirror and molecular models, to illustrate molecular…
