An integrated system comprising a commercial high-performance liquid chromatography HPLC (except autosampler) equipped with an external multichannel autofeeding module was developed to accomplish interference-free separation and kinetic tracking for the H[subscript 2]O[subscript 2]-thiourea reaction, which is proposed as a lab experiment for…

This laboratory experiment was divided into four parts. In the first part, students evaluate previously published data and check their normality using histograms, Q-Q plots, the Shapiro-Wilk test, and boxplots. In the second part, two different groups were compared. First, data normality and homoskedasticity were checked by using the Shapiro-Wilk…

Discussion is a vital component of the scientific process and dialogic learning opportunities support student learning gains and scientific epistemic learning. Discussions can improve connections between concepts and support student engagement which can increase retention in STEM programs. It has also been reported that a correlation exists…

Responding to student writers and their work is a staple of composition instruction, and there are numerous guides that offer educators advice on response strategies. However, such guides are often based on untested theories or assumptions about the effectiveness of those strategies, with little data-driven evidence of whether they work as hoped…

In this action research study, I propose a guided inquiry alternative to the traditional physical chemistry laboratory module where the equilibrium constant of acetic acid is determined conductometrically. I complement the guided inquiry structure with a 360° feedback support framework for the preparation and assessment of a laboratory report. The…

A laboratory experiment was designed and implemented in a STEM teaching laboratory at Michigan State University to engage students in an activity that not only introduced an innovative nitrate detection technique but also addressed one of the negative impacts of climate change, that is, the eutrophication of water bodies. The adverse effects of…

Commercial escape rooms have grown in popularity as an enjoyable experience that also doubles as an exercise in communication and collaboration. Educators can take advantage of these natural qualities to engage and support students in a low-stress learning environment. The primary goal of this study is to share the development and application of…

This action research study aimed to integrate simulation-enhanced interprofessional education (Sim-IPE) into the undergraduate clinical laboratory science (CLS) program curriculum. The undergraduate CLS curriculum was comprised of didactic coursework and hands-on learning experiences in the student laboratory. This traditional CLS curriculum model…

In both general chemistry and analytical chemistry courses, students are introduced to the concept of predominant species in solution when discussing acid/base chemistry. Speciation diagrams are often used to illustrate the concept and predict the relative abundance of species in solution. Herein, we describe a laboratory experiment for an…

A Fourier transform infrared (FTIR) experiment appropriate for an upper-level undergraduate laboratory such as chemical instrumentation is described. Students collect FTIR spectra of four protio-solvents and their deuterated analogues. In addition to qualitatively observing C-H and O-H peaks shift to lower energy upon deuteration, students apply a…

Writing center scholars have long debated whether writers are best served by "generalist" tutors trained in writing center pedagogy or "specialist" tutors with insider knowledge about a course's content or discipline-specific discourse conventions. A potential compromise that has emerged is training tutors in the purposes and…

We have developed a curriculum for the organic chemistry laboratory in which students draw on authentic usage of spectroscopy, spectrometry, and computational chemistry to explain chemical phenomena. This curriculum, which has been continuously refined over a decade, has been explored by many thousands of students and is scalable to small and…

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…

Due to the COVID-19 pandemic, education at all levels has temporarily shifted to remote learning, hobbling an integral component of chemistry courses: the laboratory. The chemistry lab is crucial for developing student engagement and learning with hands-on, relevant experiments in a socially dynamic classroom setting. The transition to remote…

A semester-long research project for second-semester organic chemistry lab sections was developed. Student projects were based on preliminary data from faculty research that suggested the natural product neurolenin B to be a treatment for lymphatic filariasis. Students isolated neurolenins from the Central American plant "Neurolaena…
