The field of biosensors is a burgeoning area of research and employs a large number of chemistry graduates. The impact of strip tests in detecting coronavirus was palpable during the recent COVID-19 pandemic and will further drive the biosensor industry. Despite their common usage, a coherent introduction to the basics of sensing remains missing…

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…

Thomas Graham discovered the law that bears his name while studying gas diffusion into air and other gases. He also found that the same relationship held with gas effusion, the movement of gases through a pinhole into a vacuum. Modern understanding of diffusion and effusion is based on kinetic-molecular theory, and it is generally accepted that…

The COVID-19 pandemic has highlighted the importance of incorporating distance learning for long periods. However, few studies have addressed strategies to overcome the limitations caused by the lockdown. In this study, we report an active learning experience on the topic of chemical kinetics, using two "flipped class" approaches,…

The development of good learning resources on inquiry learning model with science literacy as a strategy to facilitate active learning has become a trend in education. Critical thinking ability is needed as a strategy to build students competencies in problem solving and discovery as required in science learning. This study aims to develop a set…

Here, we present a 10-week project-oriented laboratory module designed to provide a course-based undergraduate research experience in biochemistry that emphasizes the importance of biomolecular structure and dynamics in enzyme function. This module explores the impact of mutagenesis on an important active site loop for a biomedically-relevant…

Recently there has been a renewed interest in the development and use of pedagogical games, as they provide an interesting approach to the appropriation of knowledge in the context of active learning. However, most didactic games fail to completely implement a cycle of reflection and action, thereby fostering mostly lower-order thinking skills and…

New experiments for undergraduate students are needed to stimulate experiential learning in the laboratory while providing valuable training for future career development. Iodine deficiency remains a major public health concern that is monitored by measuring the median urinary iodide concentration of a population. In this context, we have…

Students in a beginning level undergraduate classical mechanics course engaged in collaborative inquiry through the "Windwalker Project". The aim of this project was for students to create a free-standing movable structure as a way of testing and applying their understanding of the conceptual and theoretical elements of the course. This…

Presented is a guided inquiry activity designed to be conducted with prenursing students using an analogous system to help develop a conceptual understanding of factors impacting enzyme kinetics and the various types of enzyme inhibition. Pre- and postconceptual understanding evaluations and effectiveness of implementation surveys were given to…

The fact that humans possess fast and slow-twitch muscle in the ratio of approximately 50% has profound implications for designing exercise training strategies for power and endurance activities. With the growth of exercise and sport science courses, we have seen the need to develop an undergraduate student laboratory that demonstrates the basic…

Chemical kinetics is an extremely important concept for introductory chemistry courses. The literature suggests that instruction in chemical kinetics is often teacher-dominated at both the secondary school and tertiary levels, and this is the case in Thailand--the educational context for this inquiry. The work reported here seeks to shift students…

An experiment in chemical kinetics as part of our Discovery Chemistry curriculum is described. Discovery Chemistry is a pedagogical philosophy that makes the laboratory the key center of learning for students in their first two years of undergraduate instruction. Questions are posed in the pre-laboratory discussion and assessed using pooled…
