Priyadarshi Bopegedera, A. M. Ranjika – Journal of Chemical Education, 2022
Marble, formed by the metamorphism of limestone, is commonly used in the construction industry and sculpting. The mineral in marble is either calcite [CaCO[subscript 3]] or dolomite [CaMg(CO[subscript 3])[subscript 2]] or sometimes both. The pure white Carrara marble from Italy was made a household name by Michelangelo, the famous sculptor of the…

Wanda M. Valsecchi; Jose M. Delfino; Javier Santos; Santiago E. Faraj – Chemistry Education Research and Practice, 2024
When teaching STEM courses, it is important to introduce state-of-the-art techniques. Students need to learn how to conduct experiments, analyse data and choose the most effective approaches to address meaningful situations. Here we present the assessment of the implementation of a structured inquiry-based activity aimed at teaching students about…

Obaya Valdivia, Adolfo E.; Osornio, Carlos Montaño; Vargas-Rodríguez, Yolanda Marina – Online Submission, 2021
In the resolution of problems in chemical kinetics and catalysis the mathematical models relate the independent variable that is usually time, with the dependent variable which is normally the concentration of a reactant. They conform to linear models, whose parameters such as the ordering to origin and the slope are kinetic parameters, applying…

Quattrucci, Joseph G. – Journal of Chemical Education, 2018
A new method for teaching advanced laboratories at the undergraduate level is presented. The intent of this approach is to get students more engaged in the lab experience and apply critical thinking skills to solve problems. The structure of the lab is problem-based and provides students with a research-like experience. Students read the current…

Brennan, Janie; Solomon, Erin D. – Chemical Engineering Education, 2019
A unit operations laboratory course was significantly modified to be an open-ended problem-based experience with an emphasis on teamwork and communication skills. Students were surveyed to assess gains in engineering self-efficacy as well as to indicate which course structure components were most beneficial to learning. Students showed significant…

Chopra, I.; O'Connor, J.; Pancho, R.; Chrzanowski, M.; Sandi-Urena, S. – Chemistry Education Research and Practice, 2017
This qualitative study investigated the experience of a cohort of students exposed consecutively to two substantially different environments in their General Chemistry Laboratory programme. To this end, the first semester in a traditional expository programme was followed by a semester in a cooperative, problem-based, multi-week format. The focus…

Ramstedt, Madeleine; Hedlund, Tomas; Björn, Erik; Fick, Jerker; Jahnke, Isa – Education Inquiry, 2016
A range of factors can lead to situations where university courses have to be taught with a very small number of students. In this paper, we report on our experiences of a chemistry course that was especially designed to encourage learning in small groups of students (four to five per course). The course design included inquiry-based approaches,…

Kelly, Resa M.; Jones, Loretta L. – Journal of Science Education and Technology, 2007
Animations of molecular structure and dynamics are often used to help students understand the abstract ideas of chemistry. This qualitative study investigated how the features of two different styles of molecular-level animation affected students' explanations of how sodium chloride dissolves in water. In small group sessions 18 college-level…
