Undergraduates often struggle writing argumentative syntheses from conflicting sources. Written guides can help in the different phases of the process involved in these tasks and are more effective when accompanied by explicit instruction. Nevertheless, there are few studies on instructional rubrics as an aid to argumentative writing and none are…

The demand for sustainable synthetic methods in modern industry has been increasing rapidly due to the requirements of environmental protection and energy conservation, which has brought organic electrochemical synthesis to the forefront nowadays. Here, a two-part laboratory experiment has been designed to train undergraduates in comprehending and…

This study aimed to uncover common difficulties and possible areas for improvement by focusing on the approaches and errors made by 3rd-year undergraduate chemistry students in solving organic synthesis problems. The study employed a purposive sampling technique to select 112 undergraduate chemistry major students to participate in this study.…

Triboluminescence is a fascinating phenomenon that can engage students' interest in chemistry. However, safe, cost-effective, and accessible laboratory experiments featuring highly triboluminescent substances are limited. To bridge this gap, we present a simple, rapid, semimicro test tube preparation of the visually engaging manganese complex…

The main purpose of this research is to determine the effect of the REACT strategy in augmented reality applications on the problem-solving skills of teacher candidates. A parallel mixed method, which converges from mixed research designs, was used in the research. The study group of the research consists of 50 teacher candidates studying at the…

Identifying effective and time-efficient approaches to teaching students how to write from scholarly sources benefits students and instructors. Students in a general psychology course learned a concrete method to improve this type of synthesis writing. The intervention was brief, consisting of viewing an online tutorial outside of class and…

The traditional approach of using PowerPoint (PPT) presentations in medical imaging theory classes hinders the spatial thinking ability of most students. Consequently, the learning outcomes are often unsatisfactory. This article proposes a naked eye three-dimensional (3D) medical imaging teaching assistant app based on augmented reality (AR)…

Purpose: The purpose of this paper is to set forth a less-costly, more flexible approach to teaching the analysis of international business development opportunities. Design/methodology/approach: The approach capitalizes upon the high-quality business condition metrics, which are necessary to inform the development decision, that have recently…

A procedure for the solution polymerization of styrene using di-"tert"-butyl peroxide (DTBP) as the initiator is described. The use of DTBP allows for end-group analysis by [superscript 1]H NMR spectroscopy and calculation of the number-average molecular weight of the polymer. This experiment was designed as a laboratory introduction to…

In an effort to repurpose expired guaifenesin tablets, experiments devised for practical instruction are reported for the preparation and isolation of the guaifenesin acetonide using a microscale kit. The laboratory experiment successfully utilizes a waste chemical in lieu of a fine chemical to illustrate the principles behind protecting groups in…

In this experiment for an introductory undergraduate organic chemistry lab, students tetraalkylate tertbutylcalix[4]arene, a bowl-shaped macrocyclic oligophenol, and examine the supramolecular chemistry of the tetraether product by proton nuclear magnetic resonance (NMR) spectroscopy. Complexation with a sodium ion reduces the conformational…

In this upper-level undergraduate experiment, students utilize micro-Raman spectroscopy to characterize graphene prepared by mechanical exfoliation and chemical vapor deposition (CVD). The mechanically exfoliated samples are prepared by the students while CVD graphene can be purchased or obtained through outside sources. Owing to the intense Raman…

An inquiry-based experiment for the organic chemistry laboratory was developed to provide students with a cognitively rich research experience. Student teams were charged with optimizing the reaction conditions for the Williamson ether synthesis of 2- fluorophenetole from 2-fluorophenol, ethyl bromide, and potassium carbonate in either absolute…

This experiment was designed and successfully introduced to complement the nanochemistry taught to undergraduate students in a useful and interesting way. Colloidal Ag nanoparticles were synthesized by a simple, room-temperature method, and the resulting suspension was then used to study the surface-enhanced Raman scattering (SERS) of methylene…

Researchers, practitioners, and policy-makers in many countries are grappling with ways to address the persistent problem of inequitable educational outcomes between advantaged and disadvantaged students. This paper reports the results of a unique cross-country, cross-cultural analysis undertaken to provide insights into teaching practices that…
