Calalb, Mihail – Athens Journal of Education, 2023
A detailed characteristic of teaching and learning approaches used within the new concept of Learning by Being (LBB) is given. The evolution of educational paradigms from Learning by Doing (LBD) and Learning by Understanding (LBU) toward LBB is analyzed. The basic idea of LBB is students' ownership on cognitive goals, or the assumption of learning…

Cortés-Figueroa, José E. – Journal of Chemical Education, 2022
This communication describes an activity where upper-level chemistry students explore the determinability of rate constant values without concentration dependences (k[subscript true]) related to a solvent-ligand exchange in a transition metal carbonyl complex. By performing a series of multivariable linear regression (MVLR) analyses of…

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…

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…

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…

Rattanakit, Parawee – Journal of Chemical Education, 2021
This paper describes an inquiry-based integrated laboratory project for green synthesis, characterization, and applications of silver and gold nanoparticles. In this project, students were able to choose their choice of plant extract as reducing and stabilizing agents, and the students also designed their own experiments. This course gave the…

Kovacevic, Tanja; Skinner, Austin; Fisk, John D.; Fishback, Vanessa; Reed, Scott M. – Journal of Chemical Education, 2020
The complete structural analysis and resynthesis of an unknown compound, selected from a library of dipeptides, provided a framework for a course that built from expository experiments toward a guided-inquiry approach. We used this semester-long lab as a replacement for conventional second semester organic chemistry laboratory and successfully…

Mirowsky, Jaime E. – Journal of Chemical Education, 2020
In mid-March 2020, due to the novel coronavirus, my 300-level Environmental Sampling Methods lecture/laboratory course transitioned to distance learning. After this move, the primary focus of the course became the laboratory. To do this, I revised my three remaining laboratory exercises (i.e., water quality, soil quality, environmental microbes)…

Cowie, Bronwen; Harrison, Christine – International Journal of Science Education, 2021
This paper provides both a summary and plenary paper for a Special Issue of papers that build on the findings of a research project that investigated formative and summative assessment methods to support and to improve inquiry-based science teaching and learning. The paper aims to unravel some of the complexity that underpins classroom assessment…

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…

Nagarajan, Subhalakshmi; Overton, Tina – Journal of Chemical Education, 2019
With a growing number of global challenges related to the environment, water, public health, and energy, there is an imminent need to teach chemistry in the context of its interconnectedness with other systems. Project- and problem-based learning are student-centered learning approaches which offer educators the opportunity to engage learners in…

Pino, Hernan; Pastor, Vanesa; Grimalt-Álvaro, Carme; López, Víctor – Journal of Chemical Education, 2019
In this article, a low-cost and pocket-sized setup for measuring CO[subscript 2] is presented. This setup is based on Arduinos, making it economic and open to modifications or improvements that satisfy other needs. It is composed of an Arduino board, a CO[subscript 2] sensor, an SD-card module, and a control panel. The device has been tested in…

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…

Kolonko, Erin M.; Kolonko, Kristopher J. – Journal of Chemical Education, 2019
Strategies for teaching NMR spectral interpretation in the undergraduate organic chemistry curriculum are often faculty-centered and can lead to student reliance on rote memorization and "guess and check" methods rather than critical-thinking skills for structure determination. This article describes a student-focused methodology for the…

Burkett, Jeremy R.; Dwyer, Timothy M. – Journal of Chemical Education, 2019
High-impact practices, and other pedagogical advancements, have been successfully used to deepen student engagement with courses over a wide variety of disciplines. Here, we describe the design, implementation, and assessment of a cross-disciplinary, inquiry-based lab course built on the proven success of these deeply engaging principles. This new…
