Alina Majcen; Sebastian Tassoti; Philipp Spitzer – Journal of Chemical Education, 2023
Microplastics have been detected in most ecosystems around the world. They affect the environment and organisms in it, including humans and possibly their health. Hence, the analysis of microplastic occurrence in the environment is highly relevant. However, there are only a few practical and easy-to-implement methods published for school use, and…

Oscar J. Moreno; Laura S. Pineda; Carlos E. A. Camargo; Marco Fidel Suarez-Herrera – Journal of Chemical Education, 2023
The rate of the sonochemiluminescence reaction of luminol in alkaline medium can be increased in the presence of carbon tetrachloride, chloroform, and bromoform. The presence of the latter activators enhances the light emission, to allow studying the kinetics of this reaction in a 4-h laboratory session using a mobile phone camera as a detector…

Saowarux Fuangswasdi; Wanlapa Aeungmaitrepirom; Vanida Nilsom; Pritsana Ralakhee; Pumidech Puthongkham – Journal of Chemical Education, 2023
The COVID-19 pandemic, which emerged in early 2020, forced educational institutions in Thailand to chiefly rely on online learning during the government mandated lockdown for almost two academic years. Although migration to the online format seems to suit lectures, it is inadequate for laboratory courses since students could not do the experiment…

Phetvilay Khattiyavong; Phattaranan Thongtaow; Sanoe Chairam; Saksri Supasorn; Purim Jarujamrus; Maliwan Amatatongchai; Duangjai Nacapricha – Journal of Chemical Education, 2023
Catalysis is an essential concept in chemistry, playing a key role in industrial processes. Catalysis has been considered to be challenging not only for university students to comprehend but also for the teachers. In this Laboratory Experiment, we have described a simple activity for demonstrating the concept of catalysis using thread-based…

Jixiang Cao; Hao Chen; Qing Song; Hong Sun; Hua Yang; Yun Bai – Biochemistry and Molecular Biology Education, 2024
Experimental teaching is an important part of postgraduate training in basic and clinical medicine. While primary cell isolation and identification are among the most important research techniques for medical graduate students, most graduate students do not understand and master these techniques before starting their research experience. In…

A. Lynn Stephens – Journal of Research in Science Teaching, 2024
It is widely recognized that we need to prepare students to think with data. This study investigates student interactions with digital data graphs and seeks to identify what might prompt them to shift toward using their graphs as thinking tools in the authentic activity of doing science. Drawing from video screencast data of three small groups…

Tracy N. Vassiliev; Douglas J. Gardner; David J. Neivandt – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2024
This STEM research project asks middle school or high school students to work towards creating ecologically friendly packaging. Packaging that can be composted instead of thrown away and collected in landfills and oceans like plastics. This inquiry uses nanocellulose and focuses on water permeability. The fibers of nanocellulose can be dried to…
