The prompt introduction of single-molecule science into undergraduates' curricula is an urgent but challenging task. However, the research experiments are often too complicated and the instruments are too expensive to be widely transferred into a compulsory course of undergraduate students. Herein, we introduce a recently developed nanopore…

Georgia Gwinnett College (GGC) is an open-access, four-year, public liberal arts college that emphasizes excellent instruction through active learning and small class sizes. The COVID-19 pandemic presented unique challenges to GGC general chemistry instructors as they sought to actively engage students in a new online setting. We reflect on the…

Active student participation is critical to the delivery of medicinal chemistry components of the pharmacy school curriculum. Carefully structured active learning strategies can promote student engagement while increasing course material application. Topic-based active learning assignments can be administered, where learners apply constructed…

In Spring 2020, East Tennessee State University, along with colleges and universities around the world, was forced to abruptly transition from face-to-face, on-campus courses to online courses in response to the global COVID-19 pandemic. This contribution reflects on the faculty and student experience of transitioning general chemistry lecture and…

Rapid developments in educational technology show its impacts on classes. One of the recent trends in science education is virtual laboratory environments. The goal of this study is to reveal the effects of inquiry-based hands-on and virtual laboratory environments on pre-service science teachers' inquiry skills. A quasi-experimental research…

Conceptually understanding chemistry requires the ability to transition among representational levels to use an understanding of submicroscopic entities and properties to explain macroscopic phenomena. Past literature describes student struggles with these transitions but provides limited information about upper-level post-secondary chemistry…

The purpose of this study was to describe the effect of multiple knowledge representations of physical and chemical changes on the development of primary pre-service teachers' cognitive structures. The study took place in an introductory general chemistry laboratory course in a four-year teacher education program. Multiple knowledge…

This research was carried out to investigate the effect of the 5E learning method and 5E method enriched with REACT strategy on student achievement in science education. The research was carried out with 64 first-year students (30 in the experimental groups, 34 in the control groups) in the Department of Primary Education at a state university in…

Reorienting organic chemistry laboratories with an emphasis on systemic thinking can only be beneficial to students. Addressing the challenges of climate change and the development of renewable resources with a fundamental reaction, such as the hydrogenation of an alkene, will allow students to see organic chemistry as a science beneficial to…

Science educators have developed a variety of assessment techniques to help students connect their scientific knowledge and bridge conceptual gaps. In chemistry, concept maps and creative exercises are the two notable assessments that have been implemented into multiple chemistry courses and indicated promising effects on students' conceptual…

The main objective of the study was to determine Pre-service Chemistry Teachers' (PCTs) understanding of isomerism related concepts of Aliphatic Hydrocarbons (AHs). To get in-depth picture of PCTs understanding on isomerism related concepts of AHs, case study was employed. The sample for this study consisted of twelve participants selected from 87…

There appears to be no published knowledge regarding how humans use unit conversions. Until very recently, acquiring such data would be essentially impossible, but mobile devices have now enabled many questions to be answered through passive "crowdsourcing" of big data sets. This work details the analysis of five years of anonymous user…

The Pre-College Summer Program at the University of Connecticut is designed to introduce upper-level high school students (rising juniors and seniors) to college life by allowing them to live on campus for a week while taking a college-level course. Within the context of this program, we developed a class designed to introduce high school students…

Excluded-volume interactions are ubiquitous to modeling the average size of polymers in solution. This paper shows how simulations can be used by students to explore the emergence of mathematical scaling relations from excluded-volume interactions. Simulations provide robust visual representations of the system, and can be used to investigate a…

Graduate teaching assistants (GTAs) often lead laboratory and tutorial sections in science, technology, engineering, and mathematics (STEM), especially at large, research-intensive universities. GTAs' performance as instructors can impact student learning experience as well as learning outcomes. In this study, we observed 11 chemistry GTAs and 11…
