Marisa Freitas; Carina Proenc¸a; Daniela Ribeiro; Maria Beatriz Quinaz-Garcia; Alberto N. Arau´jo; Eduarda Fernandes – Journal of Chemical Education, 2023
Enzymes, enzymatic kinetics, and enzyme inhibition are topics covered in undergraduate biochemistry textbooks, having perceptible relevance to everyday life. The experimental use of enzymes involved in basic physiologic processes may be of utmost pedagogic interest because they bring evidence on how a significant number of drugs are used to…

Aditi Sinha – Bioscene: Journal of College Biology Teaching, 2024
Active learning pedagogies offer opportunities to increase student engagement and interest in plants. The Mystery Plant Project is a hands-on, semester-long active learning pedagogy I developed for an introductory, undergraduate Plant Biology course. Students investigate various aspects of their mystery plant species using observations, and…

Roberts, Charis A.; Allen, Seth; Helmy, Sameh – Journal of Chemical Education, 2021
There has been dramatic growth in interest and research regarding organic photochromism in recent decades. Despite this, the topic is seldom addressed in the undergraduate chemistry curriculum. Herein, we present a straightforward and robust experiment for the second semester organic chemistry laboratory curriculum which combines multistep…

Kimberley A. Frederick; Amanda S. Harper-Leatherman – Journal of Chemical Education, 2022
The process of method development is at the heart of analytical chemistry, yet direct experimental experience with the process is rarely taught in the undergraduate laboratory. We report here an experiment that uses rapid, safe, and inexpensive paper-based microfluidics with cell phone detection in order to facilitate the development of a…

Amenda N. Chow; Peter D. Harrington; Fok-Shuen Leung – Teaching Mathematics and Its Applications, 2024
Physical experiments in classrooms have many benefits for student learning, including increased student interest, participation and knowledge retention. While experiments are common in engineering and physics classes, they are seldom used in first-year calculus, where the focus is on solving problems analytically and, occasionally, numerically. In…

Bishnu P. Regmi; Shantel Fleming – Journal of Chemical Education, 2023
Photochemical reactions are the reactions that are induced by light. Many of these reactions are found in natural processes, including photosynthesis and the formation and decomposition of ozone in the atmosphere. Classroom demonstrations are effective in enhancing students' learning and retention. Herein, we have developed a simple demonstration…

Wagner, Eugene P.; Murray, Bridget E. – Journal of Chemical Education, 2021
Chemistry of the environment has been a long-standing and important area of scientific research. Atmospheric chemistry is of particular interest in society due to the impact that rising levels of pollutants are having on the climate. It is well-known that combustion processes create CO and NO[subscript x], which leads to the creation of other…

Byran J. Smucker; Nathaniel T. Stevens; Jacqueline Asscher; Peter Goos – Journal of Statistics and Data Science Education, 2023
The design and analysis of experiments (DOE) has historically been an important part of an education in statistics, and with the increasing complexity of modern production processes and the advent of large-scale online experiments, it continues to be highly relevant. In this article, we provide an extensive review of the literature on DOE…

Wagoner, Kasey; Flanagan, Daniel – Physics Teacher, 2019
This paper describes a new lab experiment where students explore the magnetic force on a permanent magnet placed inside a short solenoid. This lab is the fourth experiment performed in the second semester of the calculus-based introductory physics course at Washington University in St. Louis. The experiment is performed using a speaker (which…

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…

Seibert, Johann; Heuser, Katrin; Lang, Vanessa; Perels, Franziska; Huwer, Johannes; Kay, Christopher W.M. – Journal of Chemical Education, 2021
Multitouch experiment instructions (MEIs), implemented as interactive eBooks, are learning tools for pupils that offer various digital support tools and enable pupils to individualize their learning. They may be applied to contexts such as inquiry-based experiments in school laboratories, which involve highly demanding cognitive processes and…

Pyott, Laura – Journal of Statistics and Data Science Education, 2021
Understanding the abstract principles of statistical experimental design can challenge undergraduate students, especially when learned in a lecture setting. This article presents a concrete and easily replicated example of experimental design principles in action through a hands-on learning activity for students enrolled in an experimental design…

Kasprowiak, Amaury; Cazier-Dennin, Francine; Danjou, Pierre-Edouard – Journal of Chemical Education, 2020
A flash purification system using prepacked cartridges containing different silica weights and particle sizes was employed to demonstrate the influence of column characteristics on chromatographic resolution. This chromatographic experiment was a helpful introduction to chromatographic courses where the influence of particle sizes was addressed…

Ru-Xin Liu; Feng Xiong; Chao Chen; Tong-Mei Ding; Shu-Yu Zhang – Journal of Chemical Education, 2023
Project-based learning is widely used in organic laboratories. This goal-oriented and inquiry-based learning model complements student-centered training. Such models focus on complicated issues or real-world problems on the frontier of chemistry. Students progress through three project phases: preproject, during the project, and postproject.…

Prempree Duangpummet; Supan Yodyingyong; Pirom Chenprakhon – Journal of Chemical Education, 2022
A simple inquiry-based activity called "Fruit Puzzle" was designed to investigate high school students' understanding of the relationship between the concepts of density and solution concentration at a submicroscopic level. The first activity allowed students to predict whether five types of fruit would sink or float in water and asked…
