The COVID-19 pandemic has caused the loss of many lives and transformed the global educational system. This has resulted in a rapid transition from face-to-face classroom meetings to online education delivery. Online education provides another opportunity to engage students during crises, such as pandemics. However, during the transition to online…

Because of COVID-19 precautions, instructors worldwide were required to introduce a variety of virtual instruction modes to complete the Spring 2020 semester. Herein we describe parallel efforts in contextualized chemistry courses at two institutions--Carthage College and Central Michigan University. These courses are primarily designed for…

This work reports the first use of rubber latex waste as the hydrophobic reagent for a low-cost, simple, and rapid fabrication of a paper towel-based experimental device (PTED) with a circular design of 5 mm to demonstrate the factors affecting chemical equilibrium; this serves as a user-friendly means for a laboratory experiment. The illustration…

After a grueling grading campaign, a chemist asked a writing and rhetoric specialist for help improving formal reports in the introductory organic chemistry lab. Together, we realized that the very best student reports employ many persuasive moves in the combined results and discussion subsection, whereas weaker papers omit the persuasive…

The topic of atomic spectra is part of university and secondary school curricula around the world. Relatively little research, however, has been done on the learning and teaching of this subject, despite the fact that it forms a foundation for advanced study in quantum mechanics, astronomy, and astrophysics. A systematic investigation into student…

Pharmaceutical analysis, as the core curriculum of chemistry, chemical engineering, and pharmaceutical engineering, contains broad and in-depth knowledge that leads to massive learning and teaching loads. There are more than 100 analytical methods of medicines in this course. As such, this subject is a big challenge for both students and…

This paper examines the current state of the implementation of green chemistry into organic chemistry textbooks. Content analysis of the 15 most used organic chemistry textbooks revealed that only 10 of them had any mention of green chemistry. In textbooks that contained mentions of green chemistry, it was mentioned on less than 1% of pages. Green…

Fast, reliable, well-resolved latent fingerprints can be planted by applying a thin coating of a 50:50 mixture of hand lotion and food-grade protein powder. Fingerprints can be revealed with iodine fuming or ninhydrin staining. This low-cost alternative to commercial latent print pads can be used in a variety of classroom or public settings where…

Introducing chemical equilibrium concepts in undergraduate general chemistry promotes improved understanding of chemical reactions. We have developed an engaging laboratory experiment exploring the equilibrium of cobalt complexation in alcohols using UV-vis spectroscopy and successfully implemented in a large general chemistry class of 378…

A contemporary undergraduate laboratory experiment incorporating parallel microscale experimentation was developed for the well-defined palladium catalyzed Suzuki-Miyaura cross coupling of 4-fluorophenylboronic acid with both 4-chloro- and 4-bromoanisole using 11 diverse phosphine ligands and one ligandless control. This laboratory introduces…

This paper focused on describing students' result of learning through assessment of, for and as learning implementations. The subjects of research were 35 students on Chemistry Department, Mathematics and Science Faculty of Surabaya State University, Indonesia. The technique of data collecting was paper test 1, 2 and 3, that it was used to measure…

Students are introduced to the concepts of static electricity at a school level and an under-graduate level. In this paper, we present an inexpensive and portable device that can be used to study the static electricity and verify polarity of the electric charge on materials in a triboelectric series. This device is developed at the Science…

Structure determination via NMR spectroscopy is a fundamental topic taught in many advanced level chemistry courses. Despite its importance as an analytical instrument, many students find the principle behind NMR-facilitated structure determination difficult to embrace. To this end, an artificial intelligence (AI) software package, namely,…

This book promotes the effective implementation and development of critical analysis in physics. It focuses on explanatory texts concerning subjects typically dealt with in secondary or higher education and addressed in an academic or popular context. It highlights the general difficulties and obstacles inherent in teaching physics and shows how…

Disease ecology classes were conducted at two residential middle school summer camps held at a university--a camp for local youth who paid tuition and a free camp for youth from statewide underserved communities including Native, low-income, and rural. Disease ecology is defined as the ecological study of host-pathogen interactions within the…
