A massive open online course (MOOC), Exploring Everyday Chemistry (eeDc), was delivered four times between 2017 and 2019, attracting a worldwide audience of over 15?000 learners from a wide range of backgrounds. This 4-week course was designed to show a variety of everyday applications of organic chemistry, targeted at high school students seeking…

Process oriented guided inquiry learning (POGIL) is a specific type of active learning centered on a learning cycle where students first explore a concept through scientific models, followed by a concept invention, and finally a concept application phase. In spite of POGIL's research-based design and the many studies showing it increases learning…

The advanced organic chemistry experiments describe the preparation of fused six-membered lactams to isoxazole and isoxazoline by employing Ugi four-component reaction (U-4CR) and intramolecular nitrile oxide cyclization (INOC) synthetic sequence. The experiments were carried out in 28 h (overnight for U-4CR) and 2 h (for INOC) using commercially…

A four week laboratory experiment was designed on the basis of a modification of the Weiss-Cook reaction for the preparation of "cis"-1,5-dimethylbicyclo[3.3.0]octane-3,7-dione. In general, this very versatile organic reaction involves a two-step process reacting biacetyl with 2 mol of dimethyl-1,3-acetonedicarboxylate to form…

Due to the concern for COVID-19, universities in Korea switched to online teaching in most chemistry courses in the spring semester, 2020. While online lectures have been available for a small number of courses in the previous semesters, it is unprecedented that most lectures should be given online. In this communication, we describe how higher…

The COVID-19 pandemic put an abrupt end to face-to-face teaching at many colleges and universities. While numerous methods for synchronous and asynchronous teaching in lecture courses were quickly deployed, laboratory instruction presented a unique set of challenges. To develop online laboratories quickly would be a daunting task for an…

The emergence of the novel coronavirus disease-19 (COVID-19) required a rapid shift from in-person instruction to remote learning in our second-semester general chemistry course at the United States Military Academy (USMA), a predominantly undergraduate institution that takes pride in faculty accessibility to students. The decision to conduct…

A case study of the COVID-19 pandemic's impact in a nonmajor chemistry class is presented. The prepandemic student engagement strategy focused on student identity within the microcommunity of the face-to-face class. The sudden switch to online instruction mandated a series of changes. Topic-specific adjustments were made within the broader frame…

In the first-year general chemistry laboratory course, instrumental data collection involving sample quantification has often been limited to absorption spectroscopy due to the inaccessibility of emission techniques suitable for large enrollments and novice users. In this laboratory experiment, students explore the complementary techniques of…

Fused filament fabrication 3D printing is a process by which three-dimensional objects are created by depositing layers of a material onto a hard, flat surface by a robot. It is often referred to as an "additive manufacturing" technique because material is added in successive layers to create an object. Because many scientific…

The aim of this study was to determine the conceptual structures of exceptionally talented students about chemical change through the use of word associations. The study was conducted with 13 exceptionally talented students in seventh grade who were attending a science and art center located in a province in western Turkey. Data were collected…

This study focuses on designing a laboratory learning program for a high school chemistry course in which students could discover the fundamental principles of Hess's law via stepwise inquiry. By exploring the chemical properties of common desiccants, mainly those that were reactive in water, students were introduced to the exothermic reaction of…

Augmented reality (AR) is a means of superimposing artificial 3D objects over the real world via a mobile device. An AR standard file format has been recently implemented on mobile devices that current students commonly own. Here we describe three relatively nontechnical methods to produce 3D AR objects for chemistry courses and demonstrate their…

Understanding the controls of the oxidation rate of iron (Fe) in oxygenated aquatic systems is fundamental for students of the Earth and Environmental Sciences as it defines the bioavailability of Fe, a trace metal essential for life. The laboratory experiment presented here was successfully developed and used during a third-year undergraduate lab…

Many classrooms in higher education are becoming increasingly diverse. Diversity is an asset when student interactions are promoted and facilitated by instructors. The challenge is, many times students are grouped together for a collaborative project without attention to or skilled support for the learning and development that can occur through…
