Williams; Zachary Conley; Hinton Antentor Jr. – Advances in Physiology Education, 2024
Physiology is an important field for students to gain a better understanding of biological mechanisms. Yet, many students often find it difficult to learn from lectures, resulting in poor retention. Here, we utilize a learning workshop model to teach students at different levels ranging from middle school to undergraduate. We specifically designed…

Polley, J. P. – Physics Teacher, 2021
While the three laws of conservation of energy, momentum, and angular momentum are all mentioned in introductory textbooks, there are few experiments through which students can investigate the conservation of angular momentum. Most experiments consist of collisions between rotating disks, in which one disk is dropped on another, or in which the…

Stark, Moray S.; Tsokou, Aimilia M.; Howells, Alix – Journal of Chemical Education, 2021
Chemical spillage has been measured for undergraduate students undertaking a laboratory practical designed to help develop their chemical handling skills. There was a low correlation found between the amount of chemical spilled and the ability to accurately carry out the primary goal of the experiment, which was to measure the concentrations of…

Kovacevic, Tanja; Skinner, Austin; Fisk, John D.; Fishback, Vanessa; Reed, Scott M. – Journal of Chemical Education, 2020
The complete structural analysis and resynthesis of an unknown compound, selected from a library of dipeptides, provided a framework for a course that built from expository experiments toward a guided-inquiry approach. We used this semester-long lab as a replacement for conventional second semester organic chemistry laboratory and successfully…

Fukumoto, Hisao; Yamaguchi, Takashi; Ishibashi, Makoto; Furukawa, Tatsuya – IEEE Transactions on Education, 2021
Contribution: This article proposes a low-cost and mobile device-based learning support system for the stepper motor, which provides Web-based remote laboratory. This system allows young engineers to learn about rotational principles, control methods, and programming in stepper motors. Background: Familiarity with electrical machinery, such as…

Hydrogen is a sustainable and climate-friendly storage for renewable energies and can directly be generated from sunlight, e.g., by photocatalytic water splitting. This article presents the photocatalytic hydrogen evolution using LED irradiation of an aqueous ZnS particle dispersion with Na[subscript 2]S and Na[subscript 2]SO[subscript 3] as…

A national survey of chemists (n = 174) explored the self-reported format and focus of postsecondary inorganic chemistry instructional laboratory curricula. Multiple instructional laboratory course formats were observed, including stand-alone inorganic chemistry instructional laboratory courses, inorganic chemistry laboratory instruction as a…

Students were tasked with the creation of videos of ordinary reactions to promote significant learning of complex concepts underlying chemical transformations. Interactive infographics were used to deliver instructions. Afterward, students planned the experimental setup for the reaction execution and video recording using their mobile phones. The…

Gibbons, Jessica A.; Garcia, Reynaldo L.; Craig, Paul A.; Yu, Gracia Fe B.; Macaulay, Janet O. – Biochemistry and Molecular Biology Education, 2020
Laboratory classes are a central element of all biochemistry and molecular biology programs. These play a role in developing students' hands-on and technical skills and also offer much more. The design of laboratory classes depends on many factors including the programs the students are enrolled in, the level they are at, employment destinations,…

Buck, Gregory W.; Chelikowsky, Derrick J.; Doyungan, Stella M.; Tahtamouni, Mohammad Emad; Turner, Jeffrey W. – Distance Learning, 2023
Due to coronavirus disease 2019 (COVID-19), universities were restricted from gathering students for in-person instruction, especially teaching hands-on techniques in microbiology laboratory courses. This report describes how a Hispanic-serving institution (HSI) transitioned to remote learning for microbiology laboratories through a model, PRUTE,…

Descriptive statistics involves summarizing and organizing data so that they can be easily understood. Even though these are basic and simple concepts, many applied science students have misconceptions about their use in applied experiments in the laboratory. Students usually receive limited or no training in how to understand the meaning of the…

In the past decade, C-H functionalization has been a very active topic of research in both academia and industry. When a H atom is replaced by an aryl (or heteroaryl) group, the transformation is termed "direct arylation". This approach to the formation of key (hetero)aryl-(hetero)aryl bonds is complementary to traditional methods, such…

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…
