Socially shared metacognition is important for effective collaborative problem solving in virtual laboratory settings, A holistic account of socially shared metacognition in virtual laboratory settings is needed to advance our understanding, but previous studies have only focused on the isolated effect of each dimension on problem solving. This…

Postsession narrative notes written by professional tutors in a health sciences university writing center had never been analyzed to identify the most common elements noted as subpar in graduate students' scholarly writing. The purpose of this basic qualitative study was to examine these notes to identify the most common elements noted as subpar…

This dissertation investigates the experiences of multilingual writers in a writing center at a major research university based in the United States. It includes interviews with the writers and with the tutors who serve multilingual writers, to understand if these writers are getting what they need in the writing center to be successful in their…

The global COVID-19 emergency disrupted educational systems and created internship crises for universities and students. In response, one west coast social work program's practicum education department developed virtual, interactive labs that addressed the Grand Challenges (GCs), increased interdisciplinary collaboration, and ensured the…

There is little doubt that the pandemic has had a significant impact on students' academic achievement and mental health across the K-16 spectrum. For undergraduate chemistry instructors, data on the number of laboratories students completed in high school and in what mode would be important information in considering what modifications could be…

An active-learning approach was employed in a project for our chemistry major students on the synthesis of biodiesel (BD) from an Amazon region oil. The project, involving activities in class and in the laboratory, was given during 8 weeks of the spring semester of 2022. The students were asked about their previous contact with the synthesis and…

We have developed a guided-inquiry laboratory exercise in which students perform viscosity measurements to infer the structure of poly(vinyl alcohol) (PVA) in aqueous solution. The activity combines both experiments and modeling. In the experimental portion of the exercise, students measure the viscosity of several solutions of PVA with differing…

This experiment demonstrates that copper(II) chloride dihydrate (CuCl[subscript 2]·2H[subscript 2]O) in different solvents (acetone, isopropyl alcohol, or water) displays divergent colors and visible-near IR spectra. Both the reactions of these solutions with 2 equiv of sodium hydroxide (NaOH) and the direct solid-state reaction of CuCl[subscript…

Electrophilic aromatic substitution reactions are common in the organic chemistry laboratory. These reactions, while ubiquitous, use corrosive reagents and halogenated or hydrophobic solvents that produce expensive and hazardous waste streams. The carboxylation of phenols (Kolbe-Schmitt reaction), although aqueous, typically involves conditions…

The COVID-19 pandemic and its related restrictions forced the reorganization of learning methodology and gave a central role to remote learning. Laboratory experiments are the most affected activity, and several alternatives were described. This work proposes to create calculation tools by simply programming in Visual Basic of Excel to emulate the…

An advanced research discovery laboratory course in inorganic chemistry has been developed to engage undergraduate students in authentic research experiences directly related to concepts and theory taught in the lecture portion of the course. The 12-week laboratory involves an initial 4 weeks of training experiments on inorganic/organometallic…

An approach to online laboratory exercises for analytical chemistry students with demonstrated practical exercises through the use of remote-controlled gas chromatography (GC) instrumentation is discussed. The approach allows for a practical-based learning activity to be carried out by students who are unable to attend in-person laboratory…

Plastic waste is a growing concern in recent years due to the massive increase in single-use plastic applications. Despite the ever-increasing amount of waste, recycling plastics is not a simple process due to difficulties in sorting, which results in significantly downgraded material properties. This hands-on lab experiment showcases the…

Performing HPLC-based experiments in the undergraduate practical classroom is difficult because of the time required to perform an analysis. This limits the type of practical to one that undertakes a simple quantitative analysis. However, with the use of sophisticated simulators, such as the one employed in this exercise, more complex experiments…

Laboratory skills assignments were developed as a novel approach to providing students with the opportunity to engage in hands-on laboratory skills development outside of the lab during the COVID-19 pandemic. Initially, the assignments were implemented within a second-year forensic chemistry course of 48 students and redesigned and modified to be…
