Jordheim, Lars Petter; Denuzie`re, Anne; Machon, Christelle; Zeinyeh, Wael – Journal of Chemical Education, 2021
The understanding of the basic principles of chromatography is of high importance for chemistry, pharmacy, and biology students. In this paper, we present a free web application which can be used as a teaching tool to introduce chromatography to undergraduate students, using one of the simplest chromatography models: the plate theory.

Nannas, Natalie J. – Bioscene: Journal of College Biology Teaching, 2021
CRISPR-Cas9 is revolutionizing how we conduct scientific research, treat disease, and develop new crops. The widespread impact of this genome-editing technology makes it critical for undergraduate students to understand and engage with this new tool. In this article, we describe a multi-week lab module that teaches undergraduates how to design…

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…

Magalhães, Alexandre L. – Journal of Chemical Education, 2020
A bachelor's degree program in chemistry typically starts with basic concepts in mathematics, physics, and chemistry. Those principles are very important because they pave the ground for future advanced studies and, therefore, one needs to present them in a clear but rigorous way. One example is provided by the mathematical notion of an iterative…

Rodrigues, H.; dos Santos, A. C.; Soares, A. – Physics Education, 2020
In this article, physical quantities related to the motion of a parachute system in the framework of Newton's law of mechanics guide an informal approach to the mathematical concept of function. Furthermore, a graphical simulator that enables visualization of the fall of object-parachutes system is presented. The article is aimed at students and…

Argu¨ello, Jose´ M.; Dempski, Robert E. – Journal of Chemical Education, 2020
Facile visualization of biomolecules is an essential component of the undergraduate biochemistry curriculum. In the past, a number of tools have been used to display biomolecules. More recently, the advent of greater accessibility to virtual reality (VR) and augmented reality (AR) programs has created a new mechanism to visualize biomolecules.…

Sidou, Lais Feltrin; Borges, Endler Marcel – Journal of Chemical Education, 2020
Principal component analysis (PCA) is one of the most important and powerful methods in chemometrics as well as in a wealth of other areas. Running a PCA results in two main elements, the score plot and the loading plot; the score plot provides the location of the samples, and the loading plot indicates correlations among variables, the trends in…

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…

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…

Pallant, Amy; Pryputniewicz, Sarah; Lee, Hee-Sun – Science Teacher, 2017
This article describes a five-day online energy module, developed by the Concord Consortium (an educational research and development organization) in which students compare the effects of various energy sources on air quality, water quality, and land use. The module's interactive models explore hydraulic fracturing, real-world data on energy…

Fulton, Lori; Collins, Lauren W.; Poeltler, Emily; Pearson, Lourdes – Science and Children, 2018
The "Next Generation Science Standards" (NGSS Lead States 2013) call for all students to be engaged in investigations that require them to use skills and knowledge related to the science and engineering practices. In this article the authors describe how the mnemonic RAD, "Record-Analyze-Develop an explanation," was used by a…

Ylizarde, Natalie Harr; Kiorpes, Lolita Cariaso – Science Teacher, 2018
Climate change is complex, requiring critical thinking on both local and global scales. Its effects vary dramatically around the world and require new strategies to help students grasp its complexity, scale, and interrelatedness. This article describes a project to help biology students think critically about climate change from a global…

Snider, Barry B. – Journal of Chemical Education, 2015
In this experiment, students carry out a modern organocatalytic reaction using IMes·HCl and NaOH to catalyze the formation of 1,3,4-triphenylcyclopentene from cinnamaldehyde and chalcone in water. Deprotonation of IMes·HCl with NaOH forms the "N"-heterocyclic carbene IMes that reacts with cinnamaldehyde to form a homoenolate equivalent…

Elwick, Alex, Ed. – CfBT Education Trust, 2014
This research was commissioned by CfBT Education Trust and carried out in conjunction with the Institute for the Future of the Mind at the University of Oxford. The project sought to establish whether teaching pupils about the brain could impact upon their beliefs about their own intelligence (amongst other motivational measures) and ultimately…

Llevot-Calvet, Núria, Ed. – IntechOpen, 2018
In a plural, complex, and diverse society, the school faces many challenges. Teachers must prepare their students for future professions, unthinkable nowadays, and the digital competences of teachers and students are one of the axes of an advanced school. This book presents a set of works rigorously elaborated by authors of different disciplines,…
