Sokratis Tselegkaridis; Theodosios Sapounidis; Dimitrios Stamovlasis – Education and Information Technologies, 2024
Laboratories are considered to play a unique role in circuits teaching. Laboratories can be traditional, with physical components and desks, or virtual with graphical simulators. Applying these facilities in teaching, students can make experiments or measurements by exploring electric circuits' features. However, an intriguing research question is…

Baudilio Coto; Inmaculada Sua´rez; Maria Jose´ Tenorio; Miguel Angel Gonza´lez – Journal of Chemical Education, 2023
The COVID-19 pandemic and its related restrictions forced the reorganization of learning methodology and gave a central role to remote learning. Laboratory experiments are the most affected activity, and several alternatives were described. This work proposes to create calculation tools by simply programming in Visual Basic of Excel to emulate the…

Jakub A. Konkol; George Tsilomelekis – Journal of Chemical Education, 2023
Preprocessing is a critical step in the analysis pipeline of spectroscopic data. However, students are rarely introduced to preprocessing when learning spectral techniques in laboratory courses which in turn may affect and delay their progress in the field. Despite its undoubtable importance, students will be mainly performing spectroscopic…

Jennifer Scoggin; K. Christopher Smith – Chemistry Education Research and Practice, 2023
In this study, we analyzed how general chemistry students generated experimental designs corresponding to general chemistry questions such as the ones typically found in general chemistry textbooks. We found that students were very successful in including experimental design aspects that were explicitly mentioned in the general chemistry…

Alain M. Beauparlant; Cassandra T. Eagle; Reza Mohseni; Colin D. McMillen – Journal of Chemical Education, 2023
We developed a single crystal X-ray crystallography experiment based on the crystal structure of sucrose (table sugar), and a more challenging experiment using Epsom salt. Both crystals are readily available in X-ray quality crystalline form. In these experiments, students mounted a crystal on a MiTeGen loop and analyzed it using a Rigaku XtaLAB…

Kunye Chen; Raghav Mahalingam; Neal Ormsbee; Rachel Schlossman; Luis Sentis – IEEE Transactions on Education, 2024
University laboratories deliver unique hands-on experimentation opportunities for STEM students, but often lack state-of-the-art equipment and provide limited access to their equipment. The University of Texas Cloud Laboratory (CLAB) provides remote access to cutting-edge series elastic actuators for student experimentation regarding…

Junxi Zou; Xiaoyu Wang; Xuan Liu; Yuan Zheng; Wei Shao; Qing-Wei Zhang; Pingping Zhu; Lingling Li – Journal of Chemical Education, 2024
The crystalline sponge method allows for direct and precise molecular structure determination of liquid and gaseous targets and thus has been recognized as a revolutionary breakthrough in crystallography. To expose undergraduates to this cutting-edge technique, we have developed a comprehensive laboratory experiment with reaction conditions and…

Alexander J. Norquist; Gabriel Jones-Thomson; Keqing He; Thomas Egg; Joshua Schrier – Journal of Chemical Education, 2023
Laboratory automation and data science are valuable new skills for all chemists, but most pedagogical activities involving automation to date have focused on upper-level coursework. Herein, we describe a combined computational and experimental lab suitable for a first-year undergraduate general chemistry course, in which these topics are…

Diego Airado-Rodri´guez; David Mun~oz de la Pen~a; Isabel Dura´n-Mera´s; Jaime Domi´nguez Manzano; Arsenio Mun~oz de la Pen~a – Journal of Chemical Education, 2022
In this paper, the development of an automatic assessor is presented, both in MATLAB and in Excel, for an analytical exercise. In particular, the emulation of an interlaboratory exercise, using the analytical determination of phosphorus in a dry detergent, carried out in the laboratory by different groups of students, was selected as a case of…

Roberto Silva de Souza Jr.; Endler Marcel Borges – Journal of Chemical Education, 2023
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…

Tong-on, Anusorn; Saphet, Parinya – Physics Education, 2021
The experiment in charging and discharging of a capacitor through a resistor is fundamentally important for studying electronics. We have developed an alternative procedure to measure the voltage drops across capacitors as a function of time. The simple apparatus controlled by an Arduino Uno microcontroller board and LabVIEW™ interface was set up.…

Ala' J. Alnaser; Justin Hoffmeier – International Journal of Mathematical Education in Science and Technology, 2024
Differential equations are widely used tools for modelling the world around us, making a course in differential equations a natural place for students to connect concrete mathematical applications to abstract concepts. Since students grasp the concepts better by applying them, introducing differential equations through modelling becomes essential.…

Peter A. C. McPherson; Lynsey Alphonso; Ben M. Johnston – Biochemistry and Molecular Biology Education, 2024
Designing a relevant and engaging curriculum for biochemistry undergraduates can be challenging for topics which are at the periphery of the subject. We have used the framework of context-based learning as a means of assessing understanding of quantum theory in a group of students in their junior year. Our context, the role of retinol in skincare,…
