Latourelle, Sandra M.; Elwess, Nancy L.; Ryan, Amy B. – Journal of Biological Education, 2020
Enzymatic activity is at the core of biological reactions. Understanding them and the chemical and environmental factors that affect reaction rates is critical for biology students. The laboratory experiment proposed here investigated these concepts, while requiring students to document, graph data, analyse results using statistics, and…

Eriksen, Kristina; Nielsen, Bjarne E.; Pittelkow, Michael – Journal of Chemical Education, 2020
We present a simple procedure to make an augmented reality app to visualize any chemical 3D model. The molecular structure may be based on crystallographic data or from computational modeling. This guide is made in such a way that no programming skills are needed, and the procedure uses free software and provides a way to visualize 3D structures…

Teke, Dilek; Sozbilir, Mustafa – Chemistry Education Research and Practice, 2019
This study aimed to identify the needs of a 10th grade congenitally blind student in an inclusive chemistry classroom and design and develop tactile materials to teach the 'energy in living systems' topic with particular emphasis on covering the symbolic language of the chemistry. A single case study design was used to carry out an in-depth and…

Dean, Natalie L.; Ewan, Corrina; Braden, Douglas; McIndoe, J. Scott – Journal of Chemical Education, 2019
Comprehension of the 3D structure of objects usually represented in 2D is a critical part of understanding molecular geometries. The frequency with which students actually get hands-on with 3D molecular structures is often limited to a singular laboratory session. We sought to develop a set of molecular shapes that were inexpensive enough not only…

Holbert, Nathan; Wilensky, Uri – Journal of the Learning Sciences, 2019
In this article we propose that educational game design should work to create games as objects-to-think-with--games that engage players in the exploration of and experimentation with personally interesting questions around domain-relevant representations. We argue that this design focuses on developing tools and interactions that the player can…

de Vries, Lisbeth Elvira; May, Michael – Biochemistry and Molecular Biology Education, 2019
This study presents an evaluation of virtual laboratory simulation for educational use in the "AP Degree Programme in Chemical and Biotechnical Science at University College Copenhagen" in Denmark. The purpose was to test if, and how, virtual laboratory simulation could be applied to a practically oriented education such as the education…

Goldston, M. Jenice; Pan, Shanlin; Boykin, Karen; Allison, Elizabeth; Wehby, Scott – Science Teacher, 2016
Nanoscience development affects almost every discipline of science, engineering, and technology. Not surprisingly, "the science of small" is also finding its way into science classrooms. In general, "nano" refers to a billionth of a meter--about 1/50,000 the width of a hair follicle. The term "nanoparticle" usually…

Askew, Jennifer; Gray, Ron – Science Teacher, 2016
British scientist John Dalton (1766-1844), French scientist Joseph Louis Gay-Lussac (1778-1850), and Italian scientist Amedeo Avogadro (1776-1856) are familiar to many chemistry students. Such students may understand the importance of Dalton's atomic theory, model how Gay-Lussac's law relates the pressure and the temperature of a gas, and use…

Thananatthanachon, Todsapon – Journal of Chemical Education, 2016
In this experiment, the students explore the synthesis of a crystalline solid-state material, barium zirconate (BaZrO3) by two different synthetic methods: (a) the wet chemical method using BaCl[subscript 2]·2H[subscript 2]O and ZrOCl[subscript 2]·8H[subscript 2]O as the precursors, and (b) the solid-state reaction from BaCO[subscript 3] and…

Debbert, Stefan L.; Hoh, Bradley D.; Dulak, David J. – Journal of Chemical Education, 2016
In this experiment for an introductory undergraduate organic chemistry lab, students tetraalkylate tertbutylcalix[4]arene, a bowl-shaped macrocyclic oligophenol, and examine the supramolecular chemistry of the tetraether product by proton nuclear magnetic resonance (NMR) spectroscopy. Complexation with a sodium ion reduces the conformational…

Rizvi, Masood Ahmad; Dangat, Yuvraj; Shams, Tahir; Khan, Khaliquz Zaman – Journal of Chemical Education, 2016
An unfavorable pH can block a feasible electron transfer for a pH dependent redox reaction. In this experiment, a series of potentiometric titrations demonstrate the sequential loss in feasibility of iron(II) dichromate redox reaction over a pH range of 0-4. The pH at which this reaction failed to occur was termed as a pH locked reaction. The…

Afanasiev, Sergey A.; Afanasiev, Mikhail S.; Zhukov, Alexander O.; Egorov, Vladimir K.; Egorov, Evgeniy V. – International Journal of Environmental and Science Education, 2016
The background of the study is that the planar film heterostructures are nowadays the most common objects nanophotonic and nanoelectronic technologies. The authors noted that, among such objects found so-called quantum wells, which are formed by a complex series of nanoscale layers are deposited with differing elemental composition, and simple…

Tsarevsky, Nicolay V.; Woodruf, Shannon R.; Wisian-Neilson, Patty J. – Journal of Chemical Education, 2016
A two-session experiment is designed to introduce undergraduate students to concepts in catalysis, transition metal complexes, polymer synthesis, and postpolymerization modifications. In the first session, students synthesize poly(glycidyl methacrylate) via low-catalyst-concentration atom transfer radical polymerization (ATRP). The…

Zheng, Fei; Zhang, Ming; Ding, Qi; Sethna, Ferzin; Yan, Lily; Moon, Changjong; Yang, Miyoung; Wang, Hongbing – Learning & Memory, 2016
Mental health and cognitive functions are influenced by both genetic and environmental factors. Although having active lifestyle with physical exercise improves learning and memory, how it interacts with the specific key molecular regulators of synaptic plasticity is largely unknown. Here, we examined the effects of voluntary running on long-term…

Kong, Yi; Douglas, Kerrie A.; Rodgers, Kelsey J.; Diefes-Dux, Heidi; Madhavan, Krishna – Journal of Engineering Education, 2017
Background: The concepts of size and scale in nanotechnology are difficult for most beginning engineering students to grasp. Yet, guidance on the specific aspects of size and scale that should be taught and assessed is limited. Purpose: This research sought to empirically develop a framework for size and scale conceptualization and provide a…
