Applying the idea of green chemistry, we extended an esterification teaching experiment with isoamyl alcohol and acetic acid and reused isoamyl acetate in the transesterification reaction with KOH as the catalyst. As a result, isoamyl alcohol was produced and could be reused for the teaching experiment. The simplified experimental method achieved…

Demographically India is in a very unique position compared to many other countries in the world. At present, the under-25 population in India is more than 50% of India's total population, and it is predicted that it would comprise ~25% of the world population within the next decade. This "demographic dividend" provides India with a…

Preparative chromatography is one of the most common and important purification techniques in organic chemistry and is employed in laboratories across the globe. In order to facilitate student proficiency with the method, a unique approach for the separation of estragole, ethyl cinnamate, and cinnamyl alcohol using microscale preparative flash…

Benzoin, an [alpha]-hydroxy ketone, is stereoselectively reduced by sodium borohydride to yield hydrobenzoin, the stereochemistry of which is determined by acetalization and analysis of the derivative by NMR spectroscopy. This classical experiment has been enhanced by modern spectroscopic and computational analysis to enable students to…

One of the more difficult concepts introduced in the first-year undergraduate course, general chemistry, is that of chirality. Typically, left and right hands are the common, macroscopic objects of reference used to demonstrate the quality of being nonsuperimposable, followed by the use of a mirror and molecular models, to illustrate molecular…

Assessment in education involves collecting and processing information related to student achievement during learning. Assessment activities help educators to find out where learners are having difficulties which for the sake of completeness requires an integrated instrument. The assessment carried out should conform to 21st-century learning…

Chemistry students should learn not only the key concepts and processes of the discipline but also how they arise, are established, and develop over time. Undergraduate programs for chemistry teachers seldom include training in the history of chemistry to prepare future teachers to put concepts in a historical context. In schools, atom and atomic…

Intelligent tutoring system (ITS) provides learners with step-by-step problem-solving support through scaffolding. Most ITSs have been developed in the USA and incorporate American instructional strategies. How do non-American students perceive and use ITS with different native problem-solving strategies? The present study compares Stoich Tutor,…

Introductory biology is a gateway course for majors and other science, technology, engineering, and mathematics (STEM) disciplines. Despite the importance of chemistry content knowledge for understanding biology, the relationship between chemistry knowledge and prior coursework and biology course performance is understudied. We used an opportunity…

Artificial intelligence (AI) has made remarkable strides in recent years, finding applications in various fields, including chemistry research and industry. Its integration into chemistry education has gained attention more recently, particularly with the advent of generative AI (GAI) tools. However, there is a need to understand how teachers'…

This study was conducted in the laboratory and Metaverse environment with "Acids-Bases," a science subject related to the Metaverse, one of today's technologies. In line with the purpose of the research, the embedded design of the mixed research method, which combined quantitative and qualitative research methods, was used. The…

The study aimed to explore the role of e-portfolios in supporting active student engagement in chemistry learning within postgraduate education in Rwanda. The researchers adopted the qualitative descriptive approach, in which a random sample of 4 chemistry students at the University of Rwanda, African Centre of Excellence for Innovative Teaching…

With the increasing reliance on digital platforms, mobile game-based phone applications provide avenues to enhance learning of complex chemical concepts. This research developed a mobile game-based phone application designed to simulate the qualitative inorganic analysis of cations, determine its effects on learning, and examine students' insights…

An elective course on chemical process separations has been developed to provide upper-level undergraduate students the opportunity to develop expertise in evaluating and potentially improving energy consumption in distillation operations. This paper presents examples of the work submitted to illustrate the pedagogy of the class. These examples…

There is a need of a component in science education that can orient students to the complexity characterising the natural sciences position in relation to a globalised risk society and the Anthropocene. Recently, the implications of the German philosophical and educational construct "Bildung" have been discussed in this regard. In this…
