Carroll, Hannah M.; Houston, Derek D.; Ankerstjerne, Suzanne; Wanamaker, Alan D., Jr. – Journal of Biological Education, 2021
Stable isotopes in natural materials provide a powerful way to study energy flow in many systems and are widely used in fields such as archaeology, ecology, forensics, geochemistry, geology, oceanography, palaeoecology and palaeoclimatology. Based on the manner in which stable isotopes fractionate in natural systems, they allow scientists to…

A laboratory exercise for undergraduate advanced students of enzymology and biocatalysis is presented. Since enzyme assays can be quenched or continuous, this experiment compares the performance of two quenching agents for lactase, in a continuous setup. Enzymatic activity of [beta]-galactosidase ("Aspergillus oryzae") was determined…

Atabek-Yigit, Elif; Senoz, Ahmet Burak – Pedagogies: An International Journal, 2023
Students' recognition of the common procedural mistakes in the chemistry laboratory was examined in this study. Data were collected from 49 undergraduates studying Science Teaching. A video in which a student is purposefully making common procedural mistakes was shown to the students, and they were asked to recognize the mistakes. A Written…

Berg, Stephanie A.; Moon, Alena – Chemistry Education Research and Practice, 2023
Both graph comprehension and data analysis and interpretation are influenced by one's prior knowledge and experiences. To understand how one's prior knowledge and experiences interact with their analysis of a graph, we conducted think-aloud interviews with general chemistry students as they interpreted a graph to determine optimal conditions for…

Yifei Chen; Longfei Cai; Jiaye Gong; Heyun Lai – Journal of Chemical Education, 2023
Photocatalytic degradation of methylene blue was implemented as a laboratory experiment by the undergraduate students majoring in chemical education using graphene (GR)/TiO[subscript 2] as a catalyst. These chemistry preservice teachers synthesized a GR/TiO[subscript 2] composite and used it to degrade wastewater containing methylene blue under…

Craig D. Campbell; Malcolm I. Stewart – Journal of Chemical Education, 2023
The reduction of nitroarenes to anilines is a key transformation with real-life context, central to the preparation of many important fine chemicals. The importance of this transformation has led to its inclusion in not only university organic chemistry courses but also preuniversity, especially in Europe. A variety of reagent combinations have…
