Gerard G. Dumancas; Noemi Carreto; Oliver Generalao; Guoyi Ke; Ghalib Bello; Arnold Lubguban; Roberto Malaluan – Journal of Chemical Education, 2023
Chemometric techniques such as partial least-squares (PLS) regression have been applied with huge success to a wide array of chemical problems including multicomponent analysis of analytes in complex mixtures. Despite this, there are few examples of laboratory pedagogical exercises that involve students in the acquisition of chemical data from…

Kamen T. Engel; Jonathan Davidson; Alison Jolley; Ben Kennedy; Alexander R. L. Nichols – Journal of Geoscience Education, 2024
A virtual microscope resource was created when face-to-face labs were halted due to the COVID-19 pandemic in March 2020 to replicate the learning goals of an introductory petrology course on microscopy. This virtual microscope resource utilized images and videos of thin sections, as well as 3D rock models to allow students to complete labs online.…

Persinger, Jonah M.; Dunham, Stacey M.; Husmann, Polly R. – HAPS Educator, 2021
Basic Human Anatomy at Indiana University is a large undergraduate anatomy class with nearly five hundred students in twelve lab sections. In the fall of 2018, we added the Virtual Human Dissector software on an interactive Sectra table to our lab to help students fill the gap between idealized anatomical models and fully prosected cadavers. We…

Ross Andrew Shalliker; Corey Manwaring – Journal of Chemical Education, 2023
Performing HPLC-based experiments in the undergraduate practical classroom is difficult because of the time required to perform an analysis. This limits the type of practical to one that undertakes a simple quantitative analysis. However, with the use of sophisticated simulators, such as the one employed in this exercise, more complex experiments…

Falconer, John L.; Hendren, Neil – Chemical Engineering Education, 2021
A virtual catalytic reactor laboratory (VCRL) experiment, which can be used in most browsers, is described. Students select feed conditions and use the VCRL to take data for a gas-phase catalytic reaction and fit kinetic parameters to a Langmuir-Hinshelwood rate expression. The VCRL contains instructions, equipment descriptions, an animated…

Paul, Noel M.; Yoder, Ryan J.; Callam, Christopher S. – Journal of Chemical Education, 2019
Fluency in both the construction and interpretation of molecular structures is a critical learning objective in the second-year organic chemistry curriculum. With the introduction of PerkinElmer's ChemDraw structure drawing tool into undergraduate laboratory courses, students are challenged to develop fundamental molecular drawing skills using…

Sikora, Arthur; Irby, Stefan M.; Hall, Bonnie L.; Mills, Stephen A.; Koeppe, Julia R.; Pikaart, Michael J.; Wilner, Samantha E.; Craig, Paul A.; Roberts, Rebecca – Journal of Chemical Education, 2020
Campus shutdowns during the SARS-CoV-2 pandemic posed unique challenges to faculty and students engaged in laboratory courses. Formerly hands-on experiments had to be quickly pivoted to emergency remote learning. While some resources existed prior to this period, many currently available online modules and/or simulations focus on a single…

Jacob C. Crislip; Esai Lopez; Cameron D. Armstrong; Taylor Petell; Laila Abu-Lail; Andrew R. Teixeira – Advances in Engineering Education, 2023
A chemical engineering student's knowledge of theory, experimental design, and real-world processes is tested and enforced in the Unit Operations laboratory courses. However, instructors are facing challenges of delivering high-quality, hands-on laboratory content with limited resources and increasingly large class sizes. Limited in-lab time is…

Leyva-Figueroa, Eugenio; Orozco-Valdivia, Magdiel; Gonzalez-Fraga, Jose; Bardullas, Ulises – Advances in Physiology Education, 2023
The analysis of spontaneous tail coiling (STC) in zebrafish embryos is a functional parameter that allows the study of motor development. It has recently gained relevance as a biomarker to assess the neurotoxicity of environmental substances. Its practicability in the laboratory makes it an excellent pedagogical tool for promoting students'…

Enid Manyaku Pitsoane – Research in Social Sciences and Technology, 2024
Student support is seen as a necessity to better students' progress. For students to succeed when studying at a distance, they need a great deal of support to adjust to the institution of higher learning. Independence theory was used as a lens to understand the role of student support staff in providing services to students. A qualitative case…

Jordheim, Lars Petter; Denuzie`re, Anne; Machon, Christelle; Zeinyeh, Wael – Journal of Chemical Education, 2021
The understanding of the basic principles of chromatography is of high importance for chemistry, pharmacy, and biology students. In this paper, we present a free web application which can be used as a teaching tool to introduce chromatography to undergraduate students, using one of the simplest chromatography models: the plate theory.
