Monte Carlo simulations for uncertainty propagation take as inputs the uncertainty distribution for each variable and an equation for the calculation of a desired quantity. The desired quantity is then calculated by randomly drawing from the specified uncertainty distributions of the input variables. This calculation is then repeated many times…

We have successfully developed a one-semester general chemistry course that meets the primary learning goals of the traditional two-semester sequence. It is appropriate for physical, life, and earth science majors. Since implementation, 88% of students who start general chemistry complete it, an increase from 72% in our prior traditional…

Following the declaration of COVID-19 as a pandemic by the World Health Organization, The University of British Columbia shifted their instruction to online delivery. This communication describes the foundational principles used in two courses: first-year Introductory Chemistry and upper-year Materials Chemistry, to navigate this transition. The…

Besides improving students' understanding of scientific concepts, chemistry teaching should also improve students' ability of applying concepts to solve problems. The research aims to explore the effects of modeling teaching on students' proficiency in solving galvanic cell problems. This research used a quasi-experimental design, and the…

Safe and high-quality water is essential from both the health and environmental perspectives. Water quality is so important that the United Nations has included water in the 17 Sustainable Development Goals of the 2030 Agenda for Sustainable Development. Thus, the adequate control and treatment of water are necessities. These tasks must be…

The combination of organic synthesis and analytical chemistry into a related laboratory experiment is an excellent demonstration of the utility of making a compound to then be used further. Herein we describe an undergraduate laboratory experiment that involves the straightforward synthesis of an internal standard, ethyl 6-acetyloxyhexanoate, for…

Formative assessment is an important component of teaching as it enables teachers to foster student learning by uncovering, interpreting, and advancing student thinking. In this work, we sought to characterize how experienced chemistry teachers notice and interpret student thinking shown in written work, and how they respond to what they learn…

TikTok is a social media video-based phone application which enables creative and engaging videos to be shared on social media platforms worldwide. TikTok has been applied to create fun, exciting, and engaging 15-60 s long chemistry outreach educational videos, to encourage public dissemination of science with a systems thinking approach. With the…

This article introduces the use of "VPython" (the "Python" programming language plus a 3D graphics module called "Visual") as a potentially valuable tool in teaching aspects of secondary school chemistry, which also provides an opportunity for students to gain some experience with manipulating and/or writing computer…

There are numerous influential factors contributing to students' successful learning in introductory chemistry courses. One popularized factor is mathematical preparedness as gauged by a prerequisite mathematics grade or a standardized exam score. Less well known factors are students' attitude toward the subject of chemistry or students'…

High school chemistry teachers struggle to use assessment results to inform instruction. In the absence of expert assistance, teachers often look to their peers for guidance and support; however, little is known about the assessment beliefs and practices of high school chemistry teachers or the discourse mechanisms used as teachers support one…

First-semester general chemistry is a known "gatekeeper" course due to its high failure rate. These higher education courses are taken by students who for the most part are regularly admitted freshmen, yet many struggle to succeed. In this investigation researchers from six higher-education institutions of varied sizes with student…

We demonstrate that the simplicity of preparing functional microfluidic devices using 3D printing is well suited for undergraduate laboratories. Educational experiments utilizing non-paper-based microfluidic devices are often relegated to well-equipped, resource rich universities because traditional fabrication techniques require specialized and…

Connecting chemical concepts with real-world applications has been demonstrated to increase persistence, student attitudes, and performance. In a one-semester general chemistry course, most laboratory exercises were designed to have direct implications on real-world issues, and students were asked to consider these implications. Students blogged…

An open-source repository of basic building block models design files for writing chemical formulas, equations, and ionic states are provided. Writing chemical symbols, molecules, and ions in their correct oxidation state or valency in chemical equations is an essential and integral part of learning. For a visually impaired student, it is very…
