We present the results of a qualitative research study designed to explore differences in the types of reasoning triggered by information presented to chemistry students in two different formats. One group of students was asked to analyze a sequence of images designed to represent critical elements in the explanation of a target phenomenon.…

Chemical symbol representation is used extensively in chemistry classrooms; however, due to its abstract nature, many students struggle with learning and effectively utilizing these symbolic representations, which can lead to ongoing failure in subsequent chemistry learning. Taking the perspective of learning progressions, this study identifies…

This research aimed to provide an innovative chemistry learning material with guided tasks to improve students' competence in Chemistry. It involved 180 students enrolled in the Analytical Chemistry course at State University of Medan in academic year of 2016/2017. The samples were purposively selected and divided into two groups. The research…

Chemistry education has been affected in various aspects, especially teaching models, teaching technology, curriculum design, and teaching assessment, in Chinese Mainland since COVID-19 struck. To explore the change in teaching performance and differences in those teaching performances between middle school teachers and university teachers, this…

Diversity, equity, and inclusion (DEI) practices are a hallmark of high-impact pedagogy. Such practices are common in discussions regarding the retention of all students in STEM, but especially those with identities such as Black, Indigenous, persons of color, female, and LGBTQIA+. However, the extent to which DEI-framed content improves alignment…

This book presents state-of-the-art educational technologies and teaching methodologies and discusses future educational philosophies in support of the global academic society. "New Updates in E-Learning" is a collection of chapters addressing important issues related to effective utilization of the Internet and Cloud Computing, virtual…

Since the introduction of Morrison and Boyd's textbook in organic chemistry over 50 years ago, reaction mechanisms and mechanistic reasoning using the electron-pushing formalism (EPF) have become a mainstay of organic chemistry courses. In recent years there have even been several papers in this Journal and others detailing research on how…

Undergraduate curricula have increasingly incorporated sustainable and environmentally friendly approaches in the laboratory. Learning outcomes have emphasized the importance of the principles of green chemistry, but experiments may fail to impress upon the students that large-scale conversions of biomass into a spectrum of value-added products…

Esters are volatile and pleasantly smelling compounds, commonly used as food additives. Using Ti(OBu)[subscript 4]-catalyzed acyl exchange, we demonstrate a scent transmutation experiment, in which two fragrant esters swap their acyl and alkoxy substituents and are, during the course of a reactive distillation, quantitatively converted into two…

The COVID-19 pandemic has fundamentally changed many aspects of our world including the way we teach chemistry. Our emergence from the pandemic provides an opportunity for deep reflection and intentional action about what we teach, and why, as well as how we facilitate student learning. Focusing on foundational postsecondary chemistry courses, we…

An exam wrapper is a reflective exercise completed after an exam, designed to help foster students' metacognition and self-regulation. Typical exam wrappers ask students how they studied, what they missed and why, and how they would change their study behaviors to improve on the next exam. In small classes, exam wrappers can be administered as…

This study aimed to investigate the item "Response Time Fidelity scores" ("RTFs"), "KuderRichardson Reliability" ("KR[subscript 20]") and "Cronbach's Alpha Reliability" ("alpha") coefficients, calculate "KR[subscript 20]" coefficients with "RTFs" for 30 threshold…

This empirical study analyzed data from 638 teachers and 11,800 students in low-socioeconomic status (SES) urban schools (and schools with urban characteristics) exploring associations of school, teacher, teaching, and professional development characteristics toward student performance on the revised Advanced Placement (AP) Biology and AP…

The New Haven Local Section of the American Chemical Society held a virtual version of its annual Student Research Symposium prompted by the COVID-19 pandemic. A combination of YouTube, Google Drive, Open Broadcaster Software, and Zoom was utilized to hold the symposium which included juried oral and poster presentations. While our aim was to…

The College of New Jersey's Chemistry Department and School of Science have been strategically transforming our teaching, learning, and mentoring environments for over a decade through programs that are targeted toward "new majority" students: low-income, first generation, and historically marginalized races and ethnicities. Recently, we…
