Li, Zhuoxuan; Yuan, Ling; Liu, Mengfei; Cheng, Zhenfang; Zheng, Juhua; Epstein, Irving R.; Gao, Qingyu – Journal of Chemical Education, 2021
The Briggs-Rauscher reaction is a popular demonstration to illustrate chemical oscillations in laboratories, classrooms, and public seminars because of its simplicity and visual appeal. Here, we adapt the Briggs-Rauscher reaction to present reaction-diffusion-convection patterns in the undergraduate general or physical chemistry laboratory. By…

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…

Williams, Hollis – Physics Teacher, 2023
A key concept in current fluid dynamics and its applications to biology and technology is a phenomenon known as wetting. Wetting is familiar from everyday life and is simply the ability of a liquid to stay in contact with a solid surface. The wettability depends on the properties of the liquid and the solid and can be characterized by the static…

Jolley, Dianne F.; Wilson, Stephen R.; Kelso, Celine; O'Brien, Glennys; Mason, Claire E. – Journal of Chemical Education, 2016
This project utilizes visual and critical thinking approaches to develop a higher-education synergistic prelab training program for a large second-year undergraduate analytical chemistry class, directing more of the cognitive learning to the prelab phase. This enabled students to engage in more analytical thinking prior to engaging in the…

Schlosser, Sarah Elizabeth – ProQuest LLC, 2012
Students often struggle with learning complex chemistry concepts. In today's society with the advances in multimedia technology, educators have a variety of tools available to help students learn these concepts. These tools include demonstrations, videos in the popular media, and animations; referred to collectively as multimethods. With the…

Bromfield Lee, Deborah C.; Beggs, Grace A. – Journal of Chemical Education, 2021
The authors describe the construction and use of tactile models for demonstrating intermolecular forces. These models are composed of inexpensive materials and can be used in college chemistry classrooms of varying levels including general and organic chemistry. The models were designed to be paired with an accompanying activity to encourage…

Thysiadou, Anna; Gaki, Vaso – Journal of Technology and Science Education, 2021
The introduction of the computer into the educational process is a fact. The educational use of new technologies creates a new, more appealing and enjoyable learning environment. The introduction of new technologies into school differentiates the role of the professor by giving him/her a guiding character in a process of experiential approach to…

Wegwerth, Sarah E.; Overby, Jason S.; Douglas, Christopher J.; Winter, Julia E.; Manchester, Gianna J.; Engalan, Joseph – Journal of Chemical Education, 2021
As digital educational media use becomes more widespread, an opportunity exists to develop new methods to present abstract ideas to provide a more meaningful learning experience. Drawing from psychology and dynamic visualization research, new interactive tools can be thoughtfully designed but it is also necessary to establish how these media are…

Ye, Jianqiang; Lu, Shanshan; Bi, Hualin – Chemistry Education Research and Practice, 2019
This study uses graphs of conductivity measured by a microcomputer-based laboratory (MBL) to promote students' macro, micro, and symbolic representations when learning about net ionic reactions (NIR). A total of 54 students, aged 14-15 years old participated in this research, and were randomly divided into an experimental group (N = 27) and a…

Tuah, Jauyah; Harrison, Timothy G.; Shallcross, Dudley E. – Acta Didactica Napocensia, 2009
The value teachers put on university-based outreach activities designed for 14-16 year olds that involves both practical and lecture activities are discussed. A variety of good reasons for attending are provided by the teachers but the role of a School Teacher Fellow in mapping the events to the curriculum is shown to be vital to the success of…
