Ronilo Palle Antonio; Maricar Sison Prudente – International Journal of Education in Mathematics, Science and Technology, 2024
Demonstrating higher-order thinking skills is crucial for thriving in a volatile, uncertain, complex, and ambiguous (VUCA) environment. In science education, inquiry-based learning has increasingly been recognized as a potent approach to stimulate students' higher-order thinking skills. While prior research has shown evidence of its positive…

Cherif, Abour H.; Siuda, JoElla E.; Kassem, Sana; Gialamas, Stefanos; Movahedzadeh, Farahnaz – Journal of Education and Practice, 2017
One way to help students understand the scientific inquiry process, and how it applies in investigative research, is to involve them in scientific investigation. An example of this would be letting them come to their own understanding of how different variables (e.g., starting products) can affect outcomes (e.g., variable quality end products)…

Kim, Kihyang; Paik, Seoung-Hey – Journal of Chemical Education, 2021
Water electrolysis, a well-known and simple experiment, confirms that a water molecule comprises hydrogen and oxygen atoms. In this experiment, hydroxide or hydrogen ions generated from each electrode were identified using an indicator based on the assumption that electrodes, electrolytes, and indicators do not participate in the water…

Rodriguez, Jon-Marc G.; Lazenby, Katherine; Scharlott, Leah J.; Hunter, Kevin H.; Becker, Nicole M. – Journal of Chemical Education, 2020
Metamodeling ideas move beyond using a model to solve a problem to consider the nature and purpose of a model, such as reasoning about a model's empirical basis and understanding why and how a model might change or be replaced. Given that chemistry relies heavily on the use of models to describe particulate-level phenomena, developing…

Soulsby, David – Journal of Chemical Education, 2020
The free radical chlorination of an alkane experiment is often used in the undergraduate laboratory curriculum to introduce students to the free radical mechanism, substituent effects, intermediate stability, and the relative reactivity of radicals. In this experiment, students monochlorinate multiple alkanes and analyze the reaction mixture using…

Kovarik, Michelle L.; Clapis, Julia R.; Romano-Pringle, K. Ana – Journal of Chemical Education, 2020
One challenge of teaching chemical analysis is the proliferation of sophisticated, but often impenetrable, instrumentation in the modern laboratory. Complex instruments, and the software that runs them, distance students from the physical and chemical processes that generate the analytical signal. A solution to this challenge is the introduction…

Armstrong, David; Poë, Judith C. – Journal of Chemical Education, 2020
The Science of Human Health is an undergraduate chemistry course for non-science majors. This course presents chemistry content following a systems thinking approach and was created with the goal of providing students with the necessary chemistry foundation to make informed decisions which will affect their own well-being and their global…

Bliese, Sarah L.; O'Donnell, Deanna; Weaver, Abigail A.; Lieberman, Marya – Journal of Chemical Education, 2020
A two to three period analytical chemistry experiment has been developed which allows second year students to explore chemical color tests used to detect adulterated pharmaceuticals. Students prepare several paper analytical devices (PADs) to generate positive and negative controls antibiotics, along with cutting agents such as starch and chalk.…

Ling, Yizhou; Chen, Pengwen; Li, Juan; Zhang, Junyao; Chen, Kai – Journal of Chemical Education, 2020
This paper proposes an experiment in which students build microdevices for conveniently electrolyzing water and use image recognition and processing technology to measure the volume of gas generated during the reaction in a noncontact way. Taking advantage of three ratio relationships between (i) gas volume and the area of bubbles, (ii) the…

Scott, Daniel; Hilt, Cole – Journal of Chemical Education, 2019
A multiweek laboratory experiment is described, which guides students to use data to make decisions through multiple steps, before reaching a final conclusion. The lab focuses on the comparisons of fluorescence and absorbance spectroscopies to determine the concentration of a desired substance in an unknown sample in consideration of a complex…

Kean, Kelsey M.; van Zee, Kari; Mehl, Ryan A. – Journal of Chemical Education, 2019
The content and design scheme for a readily adaptable, research-based laboratory course in chemical biology are presented. In this course, students interrogate protein structure and function using the site-specific incorporation of noncanonical amino acids by genetic code expansion. The relatively new field of genetic code expansion enables…

Croisant, Michael; Bretz, Stacey Lowery; Konkolewicz, Dominik – Journal of Chemical Education, 2019
The ACS Guidelines for bachelor's degrees in chemistry call for the curriculum to include polymer chemistry principles and the synthesis of different classes of macromolecules. Organic chemistry can provide an important introduction to polymer chemistry principles, and photochemically induced radical polymerization is one method for generating…

Rodriguez Ortega, P. G.; Jaraices, R. Casas; Romero-Ariza, Marta; Montejo, M. – Journal of Chemical Education, 2019
Laboratory experiences are a key and integral part of the chemistry degree that are intended to provide the students the necessary training for laboratory work and improve their scientific reasoning/research abilities and their understanding of the uncertainty in experimental measurements. Despite the unquestionable capacity of hands-on laboratory…

Kent, James E.; Bell, Nicholle G. A. – Journal of Chemical Education, 2019
NMR is a fundamental part of any undergraduate chemistry degree, and training students how to measure and interpret NMR spectra is essential for postgraduate research or chemistry-based careers. Traditionally, the undergraduate laboratory experience with NMR is restricted to sample submission for NMR analysis, which is typically conducted by a…

King, Jorge H. Torres; Wang, Hong; Yezierski, Ellen J. – Journal of Chemical Education, 2018
Despite the importance of asymmetric catalysis in both the pharmaceutical and commodity chemicals industries, asymmetric catalysis is under-represented in undergraduate chemistry laboratory curricula. A novel guided-inquiry experiment based on the asymmetric aldol addition was developed. Students conduct lab work to compare the effectiveness of…
