Belova, Nadja; Krause, Moritz – Chemistry Education Research and Practice, 2023
Social media are a popular source of information for young people, serving the purposes of not only communication but also the creation and distribution of content as well as advertising. However, that content may contain science-related information that in many cases is not based on scientifically proven sources. Content creators and/or…

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…

Turner, Ken L., Jr.; Hoffman, Adam; Breitfelder, Scott; Wolf, Hayli; Metcalf, Isabella; Jones, Alexandra – i.e.: inquiry in education, 2020
Graphene is a novel material with extraordinary promise in various nano-based applications, including increases in strength, conductivity, filtration, and electrical capacity. Graphene can be synthesized and tested in a wide variety of applications in secondary or undergraduate settings. Allowing students to choose their own application and method…

Testa, Italo; Psillos, Dimitris; Molohidis, Anastasios – Physical Review Physics Education Research, 2020
This empirical study investigates the main features of curricula and contexts that favor or hinder the process of transfer of a teaching-learning sequence (TLS) from the designers' original situation to a host one. The specific research questions addressed were (RQ1) what were the changes made during the process of transfer in the new context?…

Compton, Owen C.; Egan, Martin; Kanakaraj, Rupa; Higgins, Thomas B.; Nguyen, SonBinh T. – Journal of Chemical Education, 2012
Periodic conductivity trends are placed in the scope of lithium-ion batteries, where increases in the ionic radii of salt components affect the conductivity of a poly(ethyleneoxide)-based polymer electrolyte. Numerous electrolytes containing varying concentrations and types of metal salts are prepared and evaluated in either one or two laboratory…

Garcia, Jennifer; Schultz, Linda D. – Journal of Chemical Education, 2016
The classic technique for sulfate analysis in an undergraduate quantitative analysis lab involves precipitation as the barium salt with barium chloride, collection of the precipitate by gravity filtration using ashless filter paper, and removal of the filter paper by charring over a Bunsen burner. The entire process is time-consuming, hazardous,…

Horvath, Thomas – Journal of College Science Teaching, 2005
In 1986, Lake Nyos, a volcanic lake in Cameroon, released a huge amount of carbon dioxide gas, killing over 1,700 people in the surrounding area. This case study, developed for use in a limnology or aquatic biology course, explores that event, introducing students to concepts relating to lake formation, thermal stratification, and dissolved gases.…

Gurses, Ahmet; Acikyildiz, Metin; Dogar, Cetin; Sozbilir, Mustafa – Research in Science & Technological Education, 2007
The aim of this study was to investigate the effectiveness of a problem-based learning (PBL) approach in a physical chemistry laboratory course. The parameters investigated were students' attitudes towards a chemistry laboratory course, scientific process skills of students and their academic achievement. The design of the study was one group…
