We discuss the successful creation and implementation of a biotechnology track within the chemical engineering unit operations course. The track focuses on engineering principles relevant to brewing. Following laboratory modules investigating heat transfer processes and yeast fermentation kinetics, student groups design and implement a project to…

Iron metabolism is an important subject of study for undergraduate students of chemistry and biochemistry. Relevant laboratory exercises are scarce in the literature but would be very helpful in assisting students grasp key concepts. The experiment described here deals with different iron release mechanisms of two protagonists in iron metabolism:…

Contribution: This study evaluates the generalizability of previously identified perceptions among engineering students of assessments in introductory programming (CS1). The students' perceptions of their instructors' and teaching assistants' (TAs) roles in these assessments are also studied, and differences based on prior programming experience,…

We present an analysis of students' thinking skills as evidenced by free-response exam problems during the COVID-19 pandemic. We compare two inquiry-based, laboratory-based classical mechanics courses, one taught online and one taught in person during the pandemic, and two inquiry-based, laboratory-based electricity and magnetism courses, one…

In this paper, we describe the transition of all five course-sections of General Biology Laboratory I from "cookbook" surveys of taxonomic domains and kingdoms to course-based undergraduate research experiences that champion inquiry-based learning in "real world" environments. We achieved this by scaling-up lessons from a…

To enhance students' learning and help them understand the whole picture of the field of inorganic chemistry, an inorganic laboratory technique course was designed that uses scaffolded, inquiry-based lab experiments and project-based learning. The scaffolded, inquiry-based laboratories taught in the first 8 weeks of the course helped students…

Course-based undergraduate research experiences (CUREs) can engage large numbers of students and provide a structured environment in which to learn valuable research skills. The ability to implement laboratory-based CUREs was hindered by the COVID-19 pandemic, generating a greater need for online options. A pilot study of an adaptation of a fully…

According to national labor market information study, access to talent is the greatest business challenge Canadian biotech companies are facing. We, therefore, developed, implemented, and assessed a pharma industry-inspired, medicinal research laboratory module in an experiential capstone biotechnology laboratory course. This involves developing a…

Technique-centered biochemistry or molecular biology undergraduate laboratory curricula do not offer significant opportunities for thoughtful, in-depth exploration of the science to foster investigative learning. To demonstrate inclusion of inquiry-driven laboratory experiments into the undergraduate biochemistry and molecular biology curricula, a…

Reported herein is a multidisciplinary experiment for senior-level undergraduate teaching laboratories in the synthesis of the analytes acetaminophen and phenacetin; the fabrication of paper-based devices, using eyeliner, acrylic spray paint, or wax-printing, for sensing of those analytes; and the use of the newly fabricated devices for successful…

Chemistry laboratories ordinarily involve a number of visual observations and require qualitative and quantitative explanations of these observations. A student with blindness at Truman State University successfully completed the laboratory portion of the non-majors liberal arts chemistry course with the assistance of a senior undergraduate…

Most didactic lab experiments deal with the influence of temperature, concentration, pressure, surface area, and catalysts on chemical kinetics; however, few of them explore the influence of light radiation and the presence of inhibitor agents on reaction rates. In order to investigate the effects of the radiation source and the presence of…

A versatile experiment is described for the high school and college laboratory setting based on the synthesis of biobased polymers prepared from inexpensive, renewable, and nonhazardous chemicals. Combinations of readily available citric acid, glycerol, and tapioca root starch are used to prepare three polymeric materials with different observable…

A multiweek laboratory experiment is described, which guides students to use data to make decisions through multiple steps, before reaching a final conclusion. The lab focuses on the comparisons of fluorescence and absorbance spectroscopies to determine the concentration of a desired substance in an unknown sample in consideration of a complex…

A new undergraduate inorganic chemistry laboratory experiment is presented. An introduction of the spectrochemical series and ligand exchange is explored using the coordination complex dirhodium tetraacetate, Rh[subscript 2](OAc)[subscript 4]. Students have measured the absorption spectra of the Rh[subscript 2] complex in the presence of various…
