Several common characteristics of the journey towards tertiary teaching expertise have been deduced through a detailed analysis of transcripts that originated from interviews conducted with ten recognised excellent tertiary chemistry teachers. The interviews were structured around Loughran's CoRe questions and yielded deep insights into the topic…

A significant challenge for the global community is the increasing demand for clean and renewable energy technologies. However, a lack of knowledge of these technologies threatens to impede their adoption. The development of cheap, effective, and easy-to-use chemical and electrochemical storage technologies is crucial if countries are to move away…

Electrostatic potential energy is a topic of great difficulty for many students. In this paper, we empirically test the utility of two approaches for laying a foundation for developing an understanding of energy in an electrostatic context, with interdisciplinary relevance. We examine student responses to a question about how the potential energy…

Statistical process control (SPC) is used in the chemical industry to monitor manufacturing and laboratory processes to ensure quality and compliance with regulatory requirements. Control charts are a key tool used in this monitoring. Industrial job postings desire experience with SPC. Most undergraduates entering the workforce have no exposure,…

The use of methanol-water mixtures as solvents for sample preparations is common in many instrumental analytical procedures for compound quantification at trace concentration levels. The reliability of the analytical method depends upon several factors including consistency of instrumental setup and calibration, quality of standards used and…

Chromatography is a ubiquitous technique in analytical chemistry, and high-performance liquid chromatography (HPLC) is the industry standard for quantitation of components in solution mixtures. However, demonstrating the principles of liquid chromatography to undergraduates via HPLC-based experiments often proves ineffective because of the fully…

3D printing was used to prepare space-filling models of electron density isosurfaces and high-resolution molecular models on the basis of the van der Waals radii of atoms. Both model types provide students with kinesthetic simulations of steric effects in bimolecular substitution and elimination reactions. The models can be printed in small sizes…

This laboratory experiment demonstrates the important utility of transition-metal complexes as catalysts in the addition reaction of carbon tetrabromide (CBr ) to select alkenes. This application offers students the opportunity to understand why transition-metal complexes are worth synthesizing. The experiment builds on fundamental theories…

A five-day discovery-based summer workshop for incoming ninth graders was designed and conducted at the University of Cincinnati (UC). The idea was to have an inquiry-based, research-driven laboratory experience where students were provided with a mentor who encouraged creativity and inquisitiveness. Over a period of three years, 33 students…

A laboratory experiment was developed that connects the interpretation of computer-generated models to the self-assembly of macrocycles. Students compare the reactions of terephthalaldehyde and isophthalaldehyde by reacting each with (R,R)-(-)-1,2-diaminocyclohexane. These isomeric systems serve as the foundation for a discussion about the impact…

This work describes the design, building, and testing of miniature, low-cost LED-LDR colorimeters for absorption-spectrophotometry experiments. It also describes using these colorimeters for simplified context-based-learning (CBL) activities in school teaching laboratories and for public-engagement events. The colorimeters are simple and robust,…

This study aims to explore the views of pre-service chemistry teachers on the nature of science and technology. Pre-service chemistry teachers' view of nature of science and technology (VNOST) is very important to help their students later in understanding the concepts of science. This research is the initial stage in didactical design research…

Educational Technology is an applied study which aims at maximizing learning by making use of the scientific and technological method and concepts developed in other social service. "Educational technology is the application of scientific knowledge about learning and conditions learning to improve the effectiveness and efficiency of teaching…

An overview of the relationship between educational research and teaching chemistry is presented, covering the opportunity areas between production and science popularization (dissemination of scientific knowledge). Knowledge apprehension and appropriation are also discussed in the educational context of UNAM, in Facultad de Estudios Superiores…

The science laboratory learning environment has been a distinctive area in science education since the 19th century. Unfortunately, students are generally not aware of what science instructors expect from laboratory experiences, and far too often, the undergraduate science laboratory curriculum lacks explicit, well-defined goals. Science…
