The Coronavirus 2019 (COVID-19) pandemic posed challenges for laboratory-based courses. The purpose of this qualitative study was to explore students' experiences, as related to engagement, in a HyFlex laboratory course that was designed for on-campus and online students to learn together. The research questions were: 1. What are the students'…

This article presents findings from an IRB-approved study about writing center social media use and nonuse using survey data keyed to five factors: reasons for nonuse; purposes for use; platforms used; approaches to use that consider platforms and target audiences; and recommendations to other writing centers to use or not use social media. While…

The construct of Computational Thinking (CT) first emerged to describe problem solving in the context of computing environments, but it has expanded to serve as a set of practices that can be applied across disciplines with or without the use of computers. We recorded students' work during two lab sessions in an undergraduate, biology-engineering…

In the past few decades, chemistry has evolved to interact with various disciplines to synergistically help tackle global challenges. This, in turn, requires that newer generations of chemistry students are trained to be more flexible in accepting and coordinating new concepts. In this experiment, pineapple was used as a key model to allow for the…

Laboratory activities are a prevalent and essential part of chemistry learning because of their potential to help students develop problem solving abilities, visualize chemistry concepts learned in lecture, and gain practical skills. However, learning in the laboratory environment is not without its challenges. For example, cookbook-style…

Sewage sludge valorization in agricultural fields is in many countries a circular economy strategy to handle the disposal issues of this complex residue. Many countries regulate the content of heavy metals and other agrochemical parameters in sewage sludge, establishing threshold limits for its application in agricultural fields. This requires the…

This article describes the design and implementation of an independent at-home chemistry project for a high school student. The pedagogical process described herein provided an authentic and meaningful laboratory experience at home, enabling remote learning that was inexpensive and safe. The topic of study was osmosis, and experiments were…

We describe a project implemented in the honors section of an upper-level analytical chemistry undergraduate course, in which students designed an experiment to compare the performance of two analytical techniques to determine the amount of ascorbic acid in a commercial sample. This project designed for 18 students is composed of three stages. In…

In this paper, the development of an automatic assessor is presented, both in MATLAB and in Excel, for an analytical exercise. In particular, the emulation of an interlaboratory exercise, using the analytical determination of phosphorus in a dry detergent, carried out in the laboratory by different groups of students, was selected as a case of…

The COVID-19 pandemic forced the transfer of face-to-face instruction to an online mode. The current study sought to describe the delivery of online biochemistry laboratories to undergraduate students. The paper also attempted to assess its advantages and disadvantages at the faculty of dental medicine of Monastir (FDMM), Tunisia. Four online…

Future college environments, including those in chemistry, will entail flexible formats. The pandemic spurred appreciation of the need, and though it has largely passed, adaptability to multiple formats in the future has been a critical part of planning for a rapidly changing future. Experiences during the pandemic will guide pedagogical changes…

We propose an innovative approach to teaching friction. Our approach aims to educate students on its microscopic nature by highlighting its origin in intermolecular interactions. We have designed a teaching sequence (TS) based on a set of experimental investigations of the properties of a gecko-inspired tape at different length scales. The TS has…

In light of COVID-19 in spring 2020, we developed a simple and versatile inquiry-based, laboratory-style active learning colorimetry experiment amenable to at-home quantitative analysis. In this experiment, students acquire an external calibration method using aqueous solutions of a self-selected chromophoric analyte from household products using…

Due to the COVID-19 pandemic, education at all levels has temporarily shifted to remote learning, hobbling an integral component of chemistry courses: the laboratory. The chemistry lab is crucial for developing student engagement and learning with hands-on, relevant experiments in a socially dynamic classroom setting. The transition to remote…

A semester-long research project for second-semester organic chemistry lab sections was developed. Student projects were based on preliminary data from faculty research that suggested the natural product neurolenin B to be a treatment for lymphatic filariasis. Students isolated neurolenins from the Central American plant "Neurolaena…
