This paper describes and assesses the impact of a new upper-level "scholarly" laboratory model that is part of a four-year scaffolded research skills curriculum at a Carnegie Bachelor's institution. In this scholarly lab model, students gain the "tools" of a discipline in a first-semester laboratory and engage in the scholarly…

The Department of Chemistry at the University of California, Irvine(UCI), instituted an upper-division "Writing for Chemists" course in fall 2017 that fulfills part of UCI's writing graduation requirement. During the 2019-2020 school year, the course was redesigned using a specifications grading system with the following goals: (1) to…

Incorporation of previously reported AR technology (ARiEL) for a general chemistry laboratory was attempted for the second time, a replication effort designed to provide students with an option to read about the nature of instruments used in an experiment. Students' app usage was tracked to understand the type and amount of information accessed,…

The Reaction Coordinate Diagram Inventory (RCDI) was developed to measure chemistry students' thinking and confidence when interpreting the kinetic and thermodynamic information encoded within reaction coordinate diagrams (RCDs). The RCDI was designed based upon analyses of qualitative data collected in semi-structured interviews with general…

A service learning course has been developed through which undergraduate science students create problem-based learning materials for use in high school science classes. Undergraduate students research active learning pedagogies with a specific focus on problem-based learning, create original materials to be used in grades 11 and 12 chemistry and…

An undergraduate laboratory experiment for the synthesis of biologically significant bis-4-hydroxycoumarins using a new catalyst is described here. An experimental setup plan, monitoring the reaction by TLC, isolation of the product, safe laboratory handling procedures, and significance of data reproducibility of the result are the main learning…

Key components of any experiential learning module are the resources students use to learn. These typically include laboratory equipment, handouts, and instructional material in the form of videos or standard operating procedures (SOPs). Their design and implementation require careful thought to ensure that students learn in an effective and…

This article introduces a novel experiment that involves vitrimers, a new type of polymer, in polymer chemistry and physics lab courses for undergraduate students. Vitrimers are permanently cross-linked networks that can be reprocessed under certain external stimuli. Therefore, they combine the advantages of traditional thermoplastics (excellent…

Service learning is a community-based educational approach where college students are connected to academic content through active participation in planned community experiences. Therefore, service learning is the form of civic engagement that we have used to connect Chemistry undergraduate students with K-12 students, teachers, and parents in our…

A laboratory experiment was developed to introduce undergraduate chemistry students to the chemical characterization of agroindustrial waste extracts by gas chromatography-mass spectrometry (GC--MS). The students prepared hexane and dichloromethane extracts from black pepper ("Piper nigrum" L.) waste. GC--MS analysis revealed the…

With the advancements in broad-spectrum sunscreens and the recent bans on benzene-based sunscreens due to their environmental toxicity, there has been a push toward broad-spectrum sunscreens containing in organic active ingredients. In this study, a procedure was developed to analyze the particle size and size distribution of inorganic active…

Teaching the fundamentals of chemical kinetics on the college level is challenging to teachers and students alike due to its abstract nature of concepts and limited connection with real context applications. This study consisted of two phases starting with designing a chemistry education for the sustainable development-based learning environment…

The educational game "Make or Take" is designed to approach the notoriously challenging topic of organic synthesis in an entertaining and engaging way. In this unique, two-part game, teams of students are given identical lists of several synthetic transformations, each requiring multiple steps to complete. During the first part of the…

Curriculum-based undergraduate research experiences (CUREs) have been shown to increase student retention in STEM fields and are starting to become more widely adopted in chemistry curricula. Here we describe a 10-week CURE that is suitable for a second-semester organic chemistry laboratory course. Students synthesize small molecules and use…

As the size of a nanoparticle is reduced, the fraction of surface atoms increases. It is interesting to note that various chemical and physical properties depend on the fraction of surface atoms. One of the most obvious questions that arise is how could one possibly estimate the fraction of surface atoms in a nanoparticle? Herein, we discuss…
