This article describes a comprehensive practical laboratory method for developing an enzyme to more easily measure glyphosate levels in solution. Through this article, undergraduate students of biology majors can conduct research experiments in critical fields by utilizing various techniques, such as chemiluminescence (CL) biosensors with…

Using a Geiger-Müller tube, sound-capturing software, and a simple computer program, students measured to reasonable precision the half-value layer of steel in absorbing high-energy gamma rays from a Radium Ore Revigator (pronounced re-vig-a-tor with the accent on "vig"), an early quack medical device. This article describes the process…

We report the design of a low-cost electrochemical workstation and open-source graphical user interface capable of performing a variety of electrochemical methods in an undergraduate teaching laboratory. The instrument--based on the popular Arduino microcontroller board--can be constructed from common components for $40 USD. The modular design of…

Molecular biology, broadly defined as the investigation of complex biomolecules in the laboratory, is a rapidly advancing field and as such the technologies available to investigators are constantly evolving. This constant advancement has obvious advantages because it allows students and researchers to perform more complex experiments in shorter…

The pharmaceutical and medicine manufacturing industry has become the largest industrial sector for the employment of chemists, indicating a need for experiments with a pharmaceutical sciences context in the undergraduate chemistry curriculum. In the pharmaceutical industry, testing drug dissolution is a key analytical task for solid oral dosage…

To best prepare students for the real-world research environment, key skills, including experimental design, data analysis, communication of results, and critical thinking, should be key components of undergraduate science courses. Furthermore, the impact of the COVID-19 pandemic on in-person teaching has resulted in a need to develop courses that…

We have developed a course-based undergraduate research experience (CURE) that can be carried out in the context of an existing second-semester or upper-level organic laboratory course. In this three-week laboratory module, students synthesize a small library of molecules, test them in a robust biological assay, and design a new compound library…

Although most instructors and institutions agree on its value, undergraduate research remains an underutilized pedagogical tool because it requires ample time, funding, and equipment. Various institutions feel these pressures differently, but for many small institutions, lack of laboratory equipment and financial support can hinder undergraduate…

At our small liberal arts college, we require undergraduates majoring in Biology and Biomedical Sciences to take a seminar in the spring of their senior year. Each year, the seminar focuses on a different topic in molecular biology and/or biochemistry. The course operates as a "journal club"--every week, a student presents a…

Advancing equity and justice in undergraduate biology education requires research to address the experiences of disabled students. Scholars working in disability studies have developed models of disability that inform Discipline-Based Education Research (DBER). To date, DBER literature has been predominantly informed by the medical and social…

A research-style laboratory experiment composed of the synthesis of MOF-74 materials, related structural characterization, and the cutting-edge application of electrocatalytic oxygen evolution reaction (OER) has been designed toward advanced undergraduates at East China University of Technology (ECUT). The desired monometallic MOF-74 (Ni-MOF-74…

This manuscript describes the implementation of a Course-based Undergraduate Research Experience (CURE) sequence in chemistry that uses research to link a lower division, organic chemistry course to an upper-division, analytical chemistry course. In the CURE sequence, students created a library of modified sugar molecules during CURE-1, Organic,…

Given the emphasis placed on laboratory reform and student engagement in authentic science practice, this manuscript outlines the development of a hybrid project-based laboratory (HPBL) curriculum centered around specific instructor goals and provides examples on how those goals were met by the experiments and how the change in curriculum affected…

CRISPR-Cas9 is revolutionizing how we conduct scientific research, treat disease, and develop new crops. The widespread impact of this genome-editing technology makes it critical for undergraduate students to understand and engage with this new tool. In this article, we describe a multi-week lab module that teaches undergraduates how to design…

This academic essay provides a strategy for teaching complementary and alternative medicine (CAM) in the classroom, a subject typically critiqued as unconventional and non-scientific. It demonstrates how students can enhance their critically reflective skills by examining polarizing and controversial medical topics, which are often considered by…
