This laboratory experiment introduces upper-division undergraduate analytical chemistry students to liquid chromatography-tandem mass spectrometry (LC-MS/MS) in a forensic application: the analysis of cocaine and metabolites of cocaine in simulated serum ostensibly from drug overdose victims. For this investigation, students developed the…

This work presents a simple protocol that demonstrates the use of an inexpensive household carbon monoxide detector as a useful tool to detect the release of carbon monoxide gas from thermal cheletropic decarbonylation reactions. The carbon monoxide detection method described has been employed in a short series of reactions used in a university…

We propose an apparatus that emulates the experiment used by Geiger and Marsden in 1913 to investigate alpha particles (Rutherford) scattering. Using a widely available fused deposition modelling 3D-printer, we built a compartmented and easily assembled educational instrument. The whole apparatus is composed of a 3D-printed chamber and an…

The remote screen control feature in Zoom was used to remotely control instrumentation during an online summer chemistry enrichment session for high school students. This feature was used to draw students into actively participating in chemistry demonstrations where instrumentation was used to gather and analyze data. It can be a challenge to keep…

This three-part laboratory experiment investigates key aspects of the Buchwald-Hartwig amination cross-coupling reaction through guided-inquiry learning strategies. The first part of this experiment utilizes high-throughput experimentation techniques to reinforce, explore, and extend fundamental concepts that are represented in the classroom,…

Within the framework of a nationwide project to boost students' enrollment in scientific disciplines in Italy, a multilevel science project was designed with a focus on the chemistry of tattoo inks, offering immediate connection with 16-18 year-old high school students. The approach takes into account time constraints, since all sessions have a…

Incorporation of previously reported AR technology (ARiEL) for a general chemistry laboratory was attempted for the second time, a replication effort designed to provide students with an option to read about the nature of instruments used in an experiment. Students' app usage was tracked to understand the type and amount of information accessed,…

Outreach initiatives are typically framed as informal learning environments that provide an opportunity to increase the participants' interest in science. Research on chemistry outreach has primarily focused on designing and implementing demonstrations for outreach. Recent studies indicate student organizations are at the forefront of chemistry…

This research aimed to examine the contributions of different sources in developing high school chemistry teachers' practical knowledge of teaching with practical work in China. The examination was conducted on a theoretical framework in which the conceptualization of PCK and nine sources of teachers' PCK were involved. Through a questionnaire…

In a world facing complex global challenges, citizens around the world need to be able to engage in scientific reasoning and argumentation supported by evidence. Chemistry educators can support students in developing these skills by providing opportunities to justify how and why phenomena occur, including on assessments. However, little is known…

The Making Introductory Courses Real while Online (MICRO) laboratory project was developed to meet the need for hands-on experiments, focused on topics in analytical chemistry, to be delivered safely remotely or in a socially distanced in-person lab. Unlike more traditional lab experiments, MICRO laboratories use only microgram or nanogram amounts…

Writing instruments, such as pens, are ubiquitous in the classroom, but their functionality is largely for one purpose: they are used to represent ideas and record information on paper. However, by replacing the conventional ink in a pen with easy-to-synthesize conducting polymer-based inks, it is possible to change a simple writing utensil into a…

Effective usage of augmented reality (AR) depends on good integration into the learning environment. Based on a qualitative research approach, this study investigates the effects of using AR technologies in science education to support the effective use of AR. Students' experiences of AR were gathered using a prepared questionnaire form. Within…

The paper describes our research aimed to verify the durability of pupils' initial ideas and concepts on the issue of acids and bases. First, we mapped their existence among primary school pupils and then compared them with the ideas of secondary and university educated adults. It has been confirmed that some initial ideas are very lasting and are…

Metacognition is an important skill for undergraduate chemistry students, but there has been scant research investigating chemistry instructors' perspectives of metacognition and the development of their students' metacognition. Since undergraduate instructors have a wide influence over what happens in their courses, it is crucial to investigate…
