This paper presents the design and reports on the use of a simple and inexpensive cloud chamber kit that is compatible with active learning, experiential learning, and project-based learning strategies. The kit was developed for use in a first-year undergraduate nuclear science seminar class at a university in the US. Diffusion cloud chambers are…

Research on teaching and learning quantum physics (QP) frequently explores students' conceptual difficulties to identify common patterns in their reasoning. The abstractness of QP is often found to be at the origin of students' conceptual difficulties. Due to this abstract nature students resort to common sense reasoning or classical thinking when…

A smartphone-based digital imaging method has been successfully introduced in an undergraduate laboratory class to quantify fluoride ions in water. Students first synthesized the chemosensor (E)-2-(1-(6-nitro-2-oxo-2H-chromen-3-yl)ethylidene)-N-phenylhydrazine-1-carbothioamide (CT) via an eco-friendly and green microwave-assisted protocol and…

Inquiry-based laboratories were implemented into a General Chemistry Laboratory sequence, and the impact of these exercises on students' experimental design skills was assessed using a four-part assessment developed for this study. This assessment contained a multiple-choice section, a section asking students to explain their reasoning behind a…

We describe a remote pedagogical approach based on chemical thinking to study metal-carbonyl complexes by analyzing simulated IR spectra. The proposed approach, implemented due to the COVID-19 pandemic, can be employed in classrooms that have very limited laboratory equipment for evaluating toxic metal-carbonyl compounds, as well as for…

The recent popularity of benchtop (BT) NMR systems has prompted its applications in undergraduate laboratories around the world. Owing to their low maintenance cost, due to the lack of a superconducting magnetic core, and simple operation, these BT NMR systems can fulfill many of the learning objectives outlined in the undergraduate organic…

The COVID-19 pandemic has forced many higher education institutions to offer their courses online, which is quite challenging when implementing laboratory sessions. Here we describe a web-based teaching resource consisting of a metallographic atlas with more than 200 micrographs corresponding to pure metals, binary alloys, steels, cast irons, and…

Many science departments encourage students to gain experience conducting research. However, finding ecological research projects that allow students to test a hypothesis in the field, over the relatively short time span of a semester, can be challenging. This article describes an inquiry-based research activity examining the influence that urban…

The rapid development of molecular biotechnology presents a curricular challenge for educators trying to provide students with relevant coursework. A comprehensive biology education should also include opportunities for students to develop intellectual and technical skills through authentic research experiences. Integrating relevant and…

While lab accidents that involved personal injuries or significant property damage are required to be reported by law, many minor lab incidents or near misses are less frequently reported, especially in an academic research environment. However, public awareness of these stories and incidents create valuable learning opportunities and can prevent…

The variation in curricular approaches to and content of chemical safety instruction in undergraduate programs highlight the need for a more comprehensive, integrative approach. This work describes the efforts of two institutions, Wittenberg University and St. Olaf College, to develop and to implement a chemical safety curriculum across the…

Communicating science with nonexperts (SciComm) is an important scientific practice. SciComm can inform decision making and public policies. Recently, seminal reports have indicated that SciComm is a practice in which students should engage. Unfortunately, students have few opportunities to engage in SciComm, partially due to the absence of a…

By focusing on food and a pervasive contaminant, this experiment engages student interest and effort while providing essential instruction and experience. As institutions are challenged by existing and emerging budgetary constraints, this experiment offers a determination approach employing commonly available instrumentation, the graphite furnace…

Professional competence is a necessary component of a person's professionalism in any area. The aim of the research is the formation of the professional activity of a future competitive specialist in the educational process of universities for the system-structural organization of professional training of biology students. The analysis of a wide…

Resonance is a fundamental concept that is necessary for students' successful learning in organic chemistry. However, there is a need to know more about both (1) what students find important when describing resonance and (2) students' conceptual understanding. This research seeks to address this discrepancy by examining second-semester organic…
