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…

Volmer, Dietrich A.; Curbani, Luana; Parker, Timothy A.; Garcia, Jennifer; Schultz, Linda D.; Borges, Endler Marcel – Journal of Chemical Education, 2017
This experiment describes a simple protocol for teaching acid-base titrations using potentiometry, conductivity, and/or photometry to determine end points without an added indicator. The chosen example examines the titratable acidity of a red wine with NaOH. Wines contain anthocyanins, the colors of which change with pH. Importantly, at the…

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?…

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…
