An experiment for the undergraduate organic chemistry laboratory involving a method for the isolation of eugenol from cloves has been developed. The experiment employs microwave-assisted extraction (MAE) of the essential oil from whole cloves using aqueous ethanol and the subsequent isolation of eugenol by acid-base extraction. The MAE allows for…

This work presents an outline for a full-quartile design-based learning laboratory-based course suitable for final year Bachelor's students. The course has been run for 5 years in the department of Chemical Engineering and Chemistry. The course attempts to provide a complete laboratory experience for its students, including an authentic research…

Synthesis and characterization of nanomaterials yields opportunities for instruction of related topics in solution chemistry and materials science, as well as spectroscopy connecting to band theory, the "particle in a box" quantum mechanical model, and thermodynamics. In collaboration with an undergraduate research assistant, we have…

Process analytical technologies (PATs) are used in the pharmaceutical and other industries to monitor chemical processes in real-time with analytical instrumentation. Each PAT analyzer brings its own advantages and disadvantages to the process, and multiplexing PAT analyzers can be advantageous as they can provide confirmatory measurements and…

Although hands-on laboratory experiments are traditionally used in schools, virtual laboratories have entered today's classrooms, due to their specific affordances. In this study, we compared the effect of using hands-on and virtual laboratories in isolation to two different combinations on middle school (7th grade) students' acquisition of…

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…

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…

The designs of many student-facing learning analytics (SFLA) dashboards are insufficiently informed by educational research and lack rigorous evaluation in authentic learning contexts, including during remote laboratory practical work. In this article, we present and evaluate an SFLA dashboard designed using the principles of formative assessment…

Physical therapy education has significantly evolved over the past few decades. While gross anatomy is integral to physical therapy education curricula, the current state of anatomy education within these programs is not well understood. The primary purpose of this report was to provide an update on the current state of anatomy education across…

This study explored how continuous diverse reflective exercises embedded in a Community Service Learning chemistry lab support science students' meaningful learning. The findings of this study are intended for those involved in teaching natural science in higher education, as well as those interested in Community Service Learning, self-directed…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] This manuscript presents a case study of an introductory physics student who, during the remote learning conditions imposed during the COVID-19 pandemic, found inspiration within a new, open-inquiry, project-based, laboratory curriculum…

Guided by the Technology Acceptance Model 3 (TAM-3), this study concerning VL focuses to examine chemistry teachers' experiences, perceived ease of use, perceived usefulness, use intentions, actual use, and factors that affect them and to create a model of the real use of VL by chemistry teachers. The research was carried out in the holistic…

One issue facing teachers who implement model-based instruction within the school system is the tight curricular schedule. The 'lesson objective tension' calls for investigations to address instructional issues such as how to organise modelling-based instruction at the curriculum level which is across multiple units. We investigated the effect of…

Research has revealed that learning, especially in the field of science, is strongly affected by various factors. These factors include students' attitudes towards the subject matter, and the manner in which the subject is taught. Given their close linkage to students' achievement, attitudes are relevant component in science learning. However,…
