Micke Reynders; Lynne A. Pilcher; Marietjie Potgieter – Journal of Chemical Education, 2023
Powerful arguments have been made recently to advocate for the introduction of systems thinking in chemistry education to equip graduates to address sustainability challenges. This contribution describes systems thinking activities and an assessment tool that enables meaningful learning in first-year organic chemistry as students engage with the…

Chatterjee, Sourav; Moon, Sooyeon; Rowlands, Amanda; Chin, Fred; Seeberger, Peter H.; Merbouh, Nabyl; Gilmore, Kerry – Journal of Chemical Education, 2021
While chemistry exists in three dimensions, it is presented in two. This down-conversion results in a significant loss in information and often necessitates multiple images/figures to convey the complexity, intricacy, and beauty of a given structure. Currently, three-dimensional models are built to allow students to interact with molecules.…

Bur, Scott K.; Pomerantz, William C. K.; Bade, Morgan L.; Gee, Clifford T. – Journal of Chemical Education, 2021
Curriculum-based undergraduate research experiences (CUREs) have been shown to increase student retention in STEM fields and are starting to become more widely adopted in chemistry curricula. Here we describe a 10-week CURE that is suitable for a second-semester organic chemistry laboratory course. Students synthesize small molecules and use…

Allen, William E.; Hosbein, Kathryn N.; Kennedy, Anthony M.; Whiting, Brandon; Walker, Joi P. – Journal of Chemical Education, 2021
This paper describes the design and implementation of a course-based undergraduate research experience (CURE) sequence in chemistry that links a lower-division, organic chemistry course to an upper-division, analytical chemistry course. The focus of student research is on blood preservation using trehalose derivatives in order to mimic the…

Toscanini, MariaA.; Recoulat Angelini, Alvaro A.; Troncoso, Maria F.; Curto, Lucrecia M. – Journal of Chemical Education, 2021
Understanding the relationship between protein structure and function can be challenging for students. Molecular visualization software aids students in this problem by allowing manipulation of structures from new and deeper perspectives. In this communication, an activity using iMolview Lite, structure visualization software for portable devices,…

Reina, Antonio; Garci´a-Ortega, Héctor; Gracia-Mora, Jesús; Mari´n-Becerra, Armando; Reina, Miguel – Journal of Chemical Education, 2022
Educational games have demonstrated that they represent valuable pedagogical instruments, which can contribute to teaching and learning in a gratifying environment. In particular in chemistry courses, an important effort has been made to facilitate complex interrelated concepts in an easy, enjoyable, and sometimes competitive way. "Compounds…

Feldman-Maggor, Yael; Tuvi-Arad, Inbal; Blonder, Ron – International Journal of Science Education, 2022
Professional development courses help teachers integrate new content knowledge into the high-school curriculum. Designing practical online courses for this purpose is challenging, particularly in emerging fields such as nanotechnology. In this study, we evaluated such a course in three complementary dimensions: (1) knowledge, (2) the complexity of…

Xue, Song; Sun, Daner; Zhu, Liying; Huang, Hui-Wen; Topping, Keith – Journal of Baltic Science Education, 2022
Analogies and modelling have been developed and applied in learning and teaching science to facilitate students' understanding of abstract concepts, such as atomic structure. Considering few studies focus on comparing the effects of two teaching strategies--analogy-based teaching (ABT) and modelling-based teaching (MBT)--this study aims to compare…

Brandon Thrope; Alan Rogerio Ferreira Lima; Alexandre Henrique Pinto – Journal of Chemical Education, 2022
Recently there is an increasing need for experiments that can be conducted remotely. In this sense, this paper presents three experiments about materials science and an X-ray diffraction (XRD) technique that can be taught and performed entirely remotely. The first experiment is about the calculation of lattice parameters, atomic radii, and…

Pérez-Mariño, Ángel M.; Blanco, M. Carmen; Buceta, David; López-Quintela, M. Arturo – Journal of Chemical Education, 2019
Until now, the concept of metal (0) atomic quantum clusters or nanoclusters (NCs) and their increasing role in nanotechnology due to their novel and exceptional properties in important industrial fields (such as catalysis) has not been included at the education level. Here, syntheses of both metal nanoparticles (NPs) and metal nanoclusters (with…

Ashwin, Paul; Blackie, Margaret; Pitterson, Nicole; Smit, Reneé – Higher Education: The International Journal of Higher Education Research, 2023
Are the ways of engaging with the world that students develop through higher education particular to bodies of knowledge they study? In this article, we examine how students' accounts of the discipline of chemistry in England and South Africa changed over the three years of their undergraduate degrees. Based on a longitudinal phenomenographic…

Sampaio, Cátia I.; Sousa, Luís F.; Dias, Alice M. – Journal of Chemical Education, 2020
Anthocyanins are natural pigments belonging to the flavonoid family that generate the red, blue, and purple colors of fruits, vegetables, and flowers. Their structure and color are dependent on various factors, like the pH. Anthocyanins appear red in acidic, purple in neutral, and blue in basic solutions, making them suitable for use as natural pH…

Heuer, Sarah E.; Neuner, Sarah M.; Hadad, Niran; O'Connell, Kristen M. S.; Williams, Robert W.; Philip, Vivek M.; Gaiteri, Chris; Kaczorowski, Catherine C. – Learning & Memory, 2020
Individual differences in cognitive decline during normal aging and Alzheimer's disease (AD) are common, but the molecular mechanisms underlying these distinct outcomes are not fully understood. We utilized a combination of genetic, molecular, and behavioral data from a mouse population designed to model human variation in cognitive outcomes to…

Wright, Lyniesha Chanell; Oliver-Hoyo, Maria Theresa – Chemistry Education Research and Practice, 2020
The mental models students have after engaging in an activity designed to teach infrared (IR) spectroscopy without reliance on IR absorption tables, were characterized. Qualitative analysis of semi-structured interviews, through open coding, allowed the classification of the mental models as Molecules as Dynamic (MAD), Bonds as Dynamic (BAD),…

Kondinski, Aleksandar; Moons, Jens; Zhang, Yujie; Bussé, Jakob; De Borggraeve, Wim; Nies, Erik; Parac-Vogt, Tatjana N. – Journal of Chemical Education, 2020
Single-type, 6-fold symmetrically grooved, and commercially accessible interlocking disks (ILDs) have been used for modeling of sp[superscript 2] hybridized carbon-based nanoarchitectures and complex polyhedral and reticular material models. In the case of the carbon-based nanoarchitectures, we showcase that the primary ILDs can be directly used…
