In this paper, the main purpose is to describe the development and use of three flowcharts for identifying types of isomers and naming coordination compounds. The first flowchart is designed to help students identify the type of isomers between the two coordination compounds. The second one is is designed to identify the type of stereoisomerism.…

As ongoing digitalization accelerates the execution of experiments and the documentation and storage of the corresponding data substantially, appropriate research data management (RDM) is a necessity to enable sustainable research at all. Consequently, a rethinking is currently taking place in academia. This process becomes visible by the…

Three-dimensional symmetry plays a crucial role in crystallography education. The educational process can be facilitated by introducing the analysis of friezes and plane patterns such as parquets before presenting more sophisticated crystal structures. Analysis of the symmetry of parquets can serve as an opportunity to follow the full routine of…

Capstone teaching laboratory activities can serve as a crucial part of the undergraduate learning experience. With this in mind, a laboratory activity that combines synthesis and multiple characterization techniques has been developed for an upper-division, laboratory-based inorganic course. Complexes of Cu(II) and Ni(II) of the amino acid glycine…

A traditional laboratory course with the primary learning outcome of improving students' theoretical knowledge has received much criticism over the years due to the lack of evidence that these goals have achieved. We report our efforts to redesign a traditional first-year organic and inorganic (also known as synthetic) laboratory course from…

Many compounds can be represented well in terms of the two-center-two-electron (2c-2e) bond model. However, it is well-known that this approach has limitations; for example, certain compounds require the use of three-center-two-electron (3c-2e) bonds to provide an adequate description of the bonding. Although a classic example of a compound that…

In place of a traditional Advanced Placement Chemistry class at the high school where I teach, I have recently developed and implemented a year-long, interdisciplinary curriculum that presents typical inorganic chemistry topics in the context of their relevant applications in archeology, art history, studio art, and the investigation,…

Simple, often artificial problems are normally preferred for introductory lab courses and are restricted to indoor participation. Microtitrations make it possible to leave the lab and study water chemistry directly in the natural environment. An exemplary outdoor challenge is presented here: travertine formation is context-rich, has to be examined…

Hydrothermal synthesis and characterization of titanosilicate ETS-10 was used as a means to prepare students for a research-focused independent term project as part of a 200-level descriptive inorganic chemistry course. Students spent the first 7 weeks of the course learning synthesis and characterization techniques that are common for metal oxide…

Instructive, inexpensive, and environmentally friendly laboratory syntheses of two highly luminescent copper(I) complexes CuI(PPh[subcript 3])[subscript 2](py[superscript R]) (py[superscript R] = pyridine, 4-cyanopyridine) are described for second-year/upper-division undergraduate inorganic chemistry students. Both complexes exhibit bright…

The catalytic hydrogenation of alkenes and alkynes is an important part of the undergraduate chemistry curriculum and is a fundamental process in chemical industry. Inquiry-based laboratory activities are presented that investigate the hydrogenation of alkynes on a nanoparticle palladium surface to form alkenes, which go on to form alkanes. Alkyne…

A laboratory experiment that involves the synthesis, characterization, and application exploration of a metal-organic framework (MOF) has been developed for first-year undergraduates in the Faculty of Engineering at National University of Singapore. The desired MOF material was prepared from commercially available reagents in a facile…

Single-type, 6-fold symmetrically grooved, and commercially accessible interlocking disks (ILDs) have been used for modeling of sp[superscript 2] hybridized carbon-based nanoarchitectures and complex polyhedral and reticular material models. In the case of the carbon-based nanoarchitectures, we showcase that the primary ILDs can be directly used…

High quality feedback on assessments and deliverables is vital to student success. This pilot study sought to understand the impact of combining positive and performance-gap feedback in an immediate feedback scenario where students were provided multiple attempts to complete an assignment. 176 online undergraduate students were surveyed after…

Problem-based learning (PBL) is an acclaimed educational concept for laboratory teaching in chemistry, which significantly affects learner motivation. A central aim of PBL is to overcome educational problems with "cook-book" laboratories. For example, when students receive experimental instructions and apply the instructions similar to…
