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…

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…

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…

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…

This communication reports the curriculum changes and how they worked when an upper-level experimental physical chemistry course had to switch from face-to-face to online teaching within a matter of days. Although several of the learning goals of the laboratory-based course could still be met in the online environment, others required…

Benefits of metacognition and active learning on student performance are well understood; however, little is known about the effect of the "explicit teaching of metacognition" combined with active learning on student performance in chemistry courses. Using a quasi-experimental study design, we investigated: (1) differences in performance…

This study aims to compare the impact of the Dual Situated Learning Model (DSLM) and conventional instructions in improving High School Students' understanding of chemical equilibrium concepts and the prevention of possible misconceptions. The study utilized a quasi-pretest-posttest control and experimental group design with two classes of XI SMAN…

In many countries, the choice of a STEM career, especially in chemistry, is decreasing. A shortage of appropriately skilled workers can become a threat to any country's future achievements. Our research strives to understand behavioral trends and career choice factors related to personal and environmental themes. Building on the foundations of the…
