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…

Powerbanks differ in the amount of energy they can store. Usually this capacity (in a colloquial sense) of the powerbanks is stated in the form of charge in mAh for effective advertising. From a physical point of view, shouldn't the energy that a powerbank can provide be of interest? For students, charging smartphones with power banks is…

Hierarchical structure and mechanics are crucial in biological systems as they allow for smaller molecules, such as proteins and sugars, to be used in the construction of large scale biological structures exhibiting properties such as structural support functionality. By exploring the fundamental principles of structure and mechanics at the…

Inquiry-based teaching is considered as contributing to content-related, procedural, and epistemic learning goals of science education. In this study, a quasi-experimental research design was utilized to investigate to what extent embedding inquiry activities in an explicit and an implicit instructional approach fosters students' ability to engage…

A workshop using dance to introduce particle physics concepts to young children is presented. The workshop is realised in the dance studio, the children assume complete ownership of the activity and dance becomes the means to express ideas. The embodiement of the physics concepts facilitates knowledge assimilation, while empowering the students…

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…

The purpose of this research was to investigate the efficacy of professional development in changing two middle school science teachers' questioning to include more questions that require deeper student responses. The professional development was based on ICAP theory which proposes a framework for identifying cognitive engagement based on what is…

Misconception is often experienced by students who study abstract subjects. If this misconception continues to be maintained then the next concept will be wrong and become a difficulty in the learning process, even if a teacher will continue the wrong concept to their students. Therefore, the researchers tried to analyze the misconceptions that…

This article showcases how a Wi-Fi based LED light system that flickers to indicate probability of auroral manifestation became a beacon of inquiry, interest, and critical thinking amongst preservice teachers, staff, and passersby in a teacher education program. Beyond articulating the design phase of the system, highlighted here are the three…

The concept of delocalization (i.e., resonance) is fundamental concept in organic chemistry but essential learning outcomes (LOs) have not previously been proposed nor has there been an analysis of how resonance is taught, despite indications in the literature that students have many non-canonical ideas about the concepts. To address this deficit,…

Electrochemistry is omnipresent in our lives, but students often do not recognize that the electrochemistry they learn in general chemistry happens in the batteries on which we depend. Students also may not recognize that they have the power to make greener choices about batteries using their knowledge of chemistry. This 4 h general chemistry…
