This article focuses on a sequence of learning experiences designed to raise children's awareness about weaving using yarn, which is one aspect of fibre and production technologies. The technologies context of the fibre production allows children to learn about the chemistry concepts related to the materials. An explicit focus on the properties…

Nuclear magnetic resonance (NMR) spectroscopy has become a cornerstone tool for studying a variety of molecular features in advanced chemistry laboratories. In this experiment, students prepare a pyrrole-[beta]-amide via a one-pot, three-step synthesis and use NMR spectroscopy to confirm its molecular structure. In addition, variable temperature…

Green chemistry metrics and life-cycle analysis (LCA) were used to assess inefficiencies in two current organic chemistry experiments conducted in third-year organic chemistry to synthesize ("E")-stilbene from benzaldehyde. An alternative Wittig-based, greener, one-pot experiment using the same starting material was selected as a vehicle…

Scaffolded inverse blended learning (SIBL) enables self-paced, individualized learning by incorporating different levels of learning activities. The SIBL approach is described for an online general chemistry course enhanced with face-to-face interactions for first-year students in an institute of higher learning. It can be easily modified and…

Whether it is prolonged strike action, a protest movement, or a global viral outbreak, the disruptions triggered in higher education are profound. In a STEM subject, laboratory classes are vital to teaching and learning. Chemistry educators had to transport laboratory skills-based teaching and assessment of courses to the virtual world at short…

The COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has disrupted normal activities all over the world. Education at all levels has been particularly hard hit, and this has resulted in the suspension of face-to-face discourse, instruction, and student assessment worldwide, with the necessity of social…

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…

A research-style laboratory experiment for advanced undergraduate students is described, which includes the synthesis, characterization, and properties (porosity, stability, amphipathy) testing of the composite [Cu[subscript 2](BTC)[subscript 4/3](H[subscript 2]O)[subscript 2][subscript 6][HPW[subscript 12]O[subscript 40]·(C[subscript…

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…

The infrared camera, or thermal imaging camera, can be used to complement the teaching of a number of topics in high school science. Here, we provide seven examples of its application in teaching physics, chemistry and biology concepts at high school level. We also discuss its strengths for such applications and provide some pointers for science…

The present study adopted a case-study qualitative design to discover how science undergraduates at one public university in the eastern U.S. understood writing and how they evaluated creative or personal writing in relation to their science identities. Findings suggest that science majors in this volunteer sample defined science writing as…

The study aimed at detecting the level of reflective teaching practices used by science teachers in classrooms. It sought to examine the potential alteration of these practices in terms of some variables, namely gender, qualification, experience, and load. The population consisted of all science teachers of physics, chemistry, and biology in the…

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…
