A symmetry activity using student-built models was developed in line with faculty-developed pedagogical goals and a collaborative learning framework. The activity took place in a 3-h laboratory portion of an upper-division inorganic chemistry course. It required students to identify symmetry elements for seven molecules using common 2D…

In this article, we describe curricular materials developed to engage undergraduate students in evolutionary thinking around antibiotic resistance using the MEGA-plate experiment (Microbial Evolution and Growth Arena). This elegant and visual experiment, developed by the Kishony Lab, shows the development of antibiotic resistance on the timescale…

Perturbation of gene expression using RNA interference (RNAi) or CRISPR interference (CRISPRi) is a useful strategy to explore the function of essential genes. In the archaeon "Haloferax volcanii," the CRISPR-Cas system has been adapted as a CRISPRi tool to silence the expression of specific genes. We developed a laboratory class (LC) to…

Polymer Chemistry is a subject in the Chemistry Programs, student have a natural curiosity about polymeric materials, that we use in our everyday activities. Our proposal is to apply cooperative learning in the Interfacial polymerization of Nylon 6,10 experimentation. The specific objectives of our project can be summarized as: To identify the…

A comprehensive laboratory-style teaching activity involving the synthesis, characterization, and analysis of structure-activity relationships of metal-organic framework (MOF) nanozymes was developed specifically for undergraduates at Tianjin University. The students acquired familiarity with the general approach in synthesizing MOFs by…

Even though scientific communication and collaboration play critical roles in academic success, they often come in second to teaching laboratory fundamentals. COVID-19 associated capacity constraints forced our program to reexamine the traditional laboratory instruction paradigm by limiting physical attendance, as well as laboratory duration.…

In an effort to improve student learning, authentic research experiences have been incorporated into introductory laboratory courses as a means to teach students scientific inquiry and engage them in the scientific process. Here, we describe the development and implementation of a novel undergraduate research-based laboratory course for first-year…

This project aims to understand physics faculty responses to transitioning to online teaching during the COVID-19 pandemic. We surveyed 662 physics faculty from the United States following the Spring 2020 term; of these, 258 completed a follow-up survey after the Fall 2020 term. We used natural language processing to measure the sentiment scores…

A green laboratory experiment has been developed in which students perform an aqueous oxidation/cycloaddition reaction to convert salicyl alcohol into a pentacyclic diepoxydione that is readily isolated by filtration. Drawing on their knowledge of periodate-mediated 1,2-diol cleavage, students propose a mechanism for the oxidation of salicyl…

Collaborative two-stage exams provide an effective mechanism to incorporate group work into summative course assessments. We implemented these exams in an upper-level biology laboratory course over two terms, one with online exams and one with in-person exams. We compared student exam performance and perceptions of two-stage exams and group work…

A method for the synthesis of flufenamic acid, a nonstereoidal anti-inflammatory drug (NSAID) of the anthranilate family (fenams), is described as an experiment for the upper-division undergraduate organic chemistry laboratory. The key step is the formation of the diarylamine moiety of flufenamic acid by a novel reaction consisting of the coupling…

The ability to visualize chemical processes can be an asset in a teaching laboratory. Despite the advances in laboratory technology, apparatuses used in the teaching of simple thermodynamics concepts, such as exothermic/endothermic reactions, historically remain unchanged and can benefit from a fresh perspective. The recent incorporation of…

To enhance students' learning and help them understand the whole picture of the field of inorganic chemistry, an inorganic laboratory technique course was designed that uses scaffolded, inquiry-based lab experiments and project-based learning. The scaffolded, inquiry-based laboratories taught in the first 8 weeks of the course helped students…

According to national labor market information study, access to talent is the greatest business challenge Canadian biotech companies are facing. We, therefore, developed, implemented, and assessed a pharma industry-inspired, medicinal research laboratory module in an experiential capstone biotechnology laboratory course. This involves developing a…

In order to introduce the concept of covalent organic frameworks (COFs), an important class of predictable crystalline porous polymers, an integrated laboratory experiment for advanced organic chemistry students is reported. The importance of these kind of polymers and their multiple applications are presented as a part of key concepts in polymer…
