Due to the COVID-19 pandemic, in-person undergraduate chemistry laboratories at North Carolina State University were not available to students during the 2020-2021 academic year and were replaced with online laboratories. With the return to in-person laboratories in the fall semester of 2021, there was widespread concern among the faculty that…

Course-based undergraduate research experiences (CUREs) have been shown to lead to multiple student benefits, but much is unknown about how CUREs lead to specific student outcomes. In this study, we examined the extent to which students making "broadly relevant novel discoveries" impacted student project ownership by comparing the…

Micellar catalysis has become an important aspect of the chemical industry's effort to "go green". However, this chemistry has yet to be fully explored in educational settings such as second-year organic chemistry laboratories. Reported herein is a discovery-based nucleophilic aromatic substitution experiment that introduces chemistry…

This work combines laboratory quantitative analysis of colored solutions and common devices for digital imaging (digital or web cameras or mobile phones, i.e., smartphones). ColorX software, specially designed for this study, was used for data collection and analysis in order to calculate concentrations of colored solutions from measured RGB…

Over the years, much criticism against animal use for physiology teaching has been made. Hence, replacement by suitable alternatives has increased in several pedagogical approaches. This study examined students' perceptions of animal versus virtual (video/computer) laboratory classes in physiological sciences associated with the effectiveness of…

Previous research shows that many students find it difficult to learn computer programming. To learn computer programming includes both gaining theoretical understanding and learning to develop programmes in practice. To this end, teachers commonly design programming exercises for the students in the computer laboratory. To be able to improve the…

In order to support physics students in their future careers, there is a need to understand the relationship between undergraduate education and professional practice in physics-related fields. This study investigated high-level goal driven mathematical problem-solving activities that are found within two disciplinary cultures: physical science…

This paper examines students' engagement in monitoring anomalous results across a 2-year longitudinal study with 9th and 10th graders (14-15 and 15-16 years of age). The context is a set of five inquiry-based laboratory tasks, requiring students to plan and carry out investigations. The study seeks to examine students' interpretation of data, in…

Undergraduates learn that gene editing in diverse organisms is now possible. How targeted manipulation of genes and genomes is utilized in basic science and biomedicine to address biological questions is challenging for undergraduates to conceptualize. Thus, we developed a lab experience that would allow students to be actively engaged in the full…

Active-learning strategies such as undergraduate research courses and course-based undergraduate research experiences (CUREs), which engage students in the practical experiments, have been reported as efficient ways for effective teaching and training of graduating students. Recently, many practical examples have been published in various fields…

Inorganic phosphors are the main component of light emitting diodes which have caused the revolution in lighting industry as an energy-efficient and long-lasting replacement of traditional incandescent light bulbs and fluorescent tubes. They are also used in various consumer products and displays and can potentially find applications in…

The effects of substitution on reaction rates are at the heart of both physical chemistry and organic chemistry. In this paper, we present a computational laboratory module to explore the effects of group substitution and isotopic substitution on reaction rates by using a readily accessible graphical interface, a computational engine, and…

Drawing on a text-based ethnography of digital writing in a biology laboratory, this article examines the text trajectory of a scientific manuscript and a scientific team's related writing for public audiences, including for citizen scientists. Using data drawn from texts, observations, interviews, and related artifacts, the author examines how…

In the field of physics teaching, the simple pendulum provides a very simple way to study the harmonic oscillator, the source of some fundamental concepts such as periodicity, relaxation time and anharmonicity. As such, its experimental study is frequently integrated into high school or first year university programs. With this in mind, in this…

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…
