Nowadays, students have digital skills that are much larger than any other student in the past. Traditional experiments in a real laboratory are still fundamental, however an increasing number of computers can be used to simulate experiments close to the experimental environment. This can be seen as a great advantage for science learning, as…

Using crystal structure data, site directed mutagenesis, and real-time kinetic assays, students designed, expressed, and purified engineered mutants of human insulin-degrading enzyme (IDE). Students designed their own IDE mutants following "in silico" analysis, used inverse PCR to generate mutant plasmid expression constructs, expressed…

Self-efficacy is a situational and subject-dependent construct instead of a personal characteristic, general perception, or personal competence. This study aimed to develop and validate a scale that would determine chemistry teachers' perceived self-efficacy for teaching in the laboratories. To this end, a self-efficacy perception scale for…

As electrochemistry continues to gain broader acceptance and use within the organic chemistry community, it is important that advanced undergraduate students are exposed to fundamental and practical knowledge of electrochemical applications for chemical synthesis. Herein, we describe the development of an undergraduate laboratory experience that…

This paper reports the quantification of Ca, Mg, and Fe as micronutrients in different vegetables (spinach, sugar beets, and carrots) from raw and processed samples. Simple extraction procedures, titrations, and spectrophotometric analysis were used to determine the amounts of micronutrients before and after cooking. From the obtained results, an…

A challenge in the pandemic era is to implement effective but flexible practical teaching for biological sciences courses. Such teaching needs to deliver conceptual, analytical and practical skills training while having the option to rapidly respond to health and safety issues, local regulations, staff and student concerns. In this paper, we…

The chlorination reaction of aromatic compounds is highly important for the synthesis of pharmaceutical products. As the most common chlorination reagent, chlorine is restricted from undergraduate laboratory experiment training due to its toxicity. In this work, we reported the chlorination of aromatic compounds with chlorine generated from the…

Over the past few decades, the photographic process has slowly vanished from chemistry education in most schools. It happened due to vast changes in both technology and legislation. It is, however, helpful in demonstrating several concepts in natural sciences, bringing a bit of art into the subjects, and giving students an opportunity to express…

In recent years, pedagogical advancements have allowed the adoption of more engaging forms of course assignments to help students better understand and communicate chemistry. In this context, informational graphics, known as infographics, emerge as an effective teaching aid in educational settings and in disseminating scientific content to the…

Chemists have always designed and deployed cross-disciplinary approaches that interface chemistry with other disciplines to proffer solutions to many human problems. We designed a laboratory experiment that implements chemistry concepts in a biological model to prime undergraduate students to appreciate interdisciplinarity as an approach to…

Investigating and understanding novel antibacterial agents is a necessary task as there is a constant increase in the number of multidrug-resistant bacterial species. The use of nanotechnology to combat drug-resistant bacteria is an important research area. The laboratory experiment described herein demonstrates that changes in the nanostructure…

Cycloadditions in combination with multicomponent reactions are among the most valuable synthetic tools used by organic chemists to construct cyclic and heterocyclic compounds in a straightforward way. Although cycloadditions, such as the Diels--Alder reaction, are mainly covered in basic and advanced organic courses for undergraduate students,…

Laboratory automation and data science are valuable new skills for all chemists, but most pedagogical activities involving automation to date have focused on upper-level coursework. Herein, we describe a combined computational and experimental lab suitable for a first-year undergraduate general chemistry course, in which these topics are…

Low-dimensional materials especially graphene-based are of high interest to a broad community. One of the most fundamental aspects in the biomedical field is material characterization, which helps understand their property and tune for application. Though the existing teaching curricula are well standardized to include basic principles and…

Substitution reactions of alcohols are some of the simplest experiments performed in undergraduate organic chemistry laboratory settings. However, the use of gas chromatography (GC) as an analytical tool for these reactions can be at times laborious and time-consuming. In this work, 1-pentanol, 2-pentanol, 3-pentanol, and 2-methyl-2-butanol were…
