Xinyun Zhao; Tsunghsueh Wu; Xi Chen; Lamei Wu; Zhongqiang Zhou – Journal of Chemical Education, 2023
An inquiry-based learning approach was implemented into comprehensive organic chemistry experiments focusing on the formation process of N-phenylbenzamide from the reaction between N-benzylideneaniline and benzoyl peroxide in commercial dimethyl sulfoxide. Students conducted comparative experiments using alternative reagents or reaction conditions…

Altowaiji, Sara; Haddadin, Rakahn; Campos, Priscilla; Sorn, Shannon; Gonzalez, Lizbeth; Villafane, Sachel M.; Groves, Michael N. – Chemistry Education Research and Practice, 2021
Chemistry laboratory experiences provide students the opportunity to engage all three domains of learning: psychomotor, cognitive and affective. However, they are often stressful environments where students are expected to quickly learn new laboratory techniques, and collect data in a short amount of time. In principle, providing additional…

George-Williams, Stephen R.; Ziebell, Angela L.; Kitson, Russell R. A.; Coppo, Paolo; Thompson, Christopher D.; Overton, Tina L. – Chemistry Education Research and Practice, 2018
The aims of teaching laboratories is an important and ever-evolving topic of discussion amongst teaching staff at teaching institutions. It is often assumed that both teaching staff and students are implicitly aware of these aims, although this is rarely tested or measured. This assumption can lead to mismatched beliefs between students and…

Flaherty, A.; O'Dwyer, A.; Mannix-McNamara, P.; Leahy, J. J. – Journal of Chemical Education, 2017
Designing and evaluating teacher development programs for graduate teaching assistants (GTAs) who teach in the laboratory is a prominent feature of chemistry education research. However, few studies have investigated the impact of a GTA teacher development program on the verbal interactions between participating GTAs and students in the…

Ghani, I. B. A.; Ibrahim, N. H.; Yahaya, N. A.; Surif, J. – Chemistry Education Research and Practice, 2017
Educational transformation in the 21st century demands in-depth knowledge and understanding in order to promote the development of higher-order thinking skills (HOTS). However, the most commonly reported problem with respect to developing a knowledge of chemistry is poor mastery of basic concepts. Chemistry laboratory educational activities are…
