Betül Demirdögen; Isaiah Nelsen; Scott E. Lewis – Chemistry Education Research and Practice, 2023
The Brønsted-Lowry acid-base model is fundamental when discussing acid and base strength in organic chemistry as many of the reactions include a competing proton transfer reaction. This model requires evaluating chemical stability "via" a consideration of electronic granularity. The purpose of this study is to identify students' mental…

Rameez Raza; Connor Pattison; Wen Zhou; Lucas Clarke; Devin Latimer; Nabyl Merbouh – Journal of Chemical Education, 2023
While elimination reactions are ubiquitous in organic chemistry textbooks, their implementation in undergraduate laboratories still suffers from a lack of reliable and easy setup procedures. This paper describes an easy-to-implement set of elimination experiments in the pentanol and bromopentane series using a modified Hickman distillation head.…

The chemistry of 4d and 4f metals was investigated at the undergraduate level in an effort to incorporate f-element chemistry in the curriculum. This was accomplished through microwave-assisted synthesis of 1,10-phenanthroline (phen) coordination compounds [Eu(phen)(subscript 3)](PF[subscript 6])[subscript 3] and [Ru(phen)(subscript…

Daisuke Kajiya – Journal of Chemical Education, 2023
The yellow-blue color pair has been used in creative artwork such as paintings and designs and in color engineering. Herein we present a method for using the yellow-blue combination in a chemistry lesson dealing with [pi]-conjugated molecules for first-year undergraduate students who are not science majors. The lesson begins with an introduction…

Michael J. Jenkins; Miranda A. Phillips; Zi-Ling Xue – Journal of Chemical Education, 2023
This experiment demonstrates that copper(II) chloride dihydrate (CuCl[subscript 2]·2H[subscript 2]O) in different solvents (acetone, isopropyl alcohol, or water) displays divergent colors and visible-near IR spectra. Both the reactions of these solutions with 2 equiv of sodium hydroxide (NaOH) and the direct solid-state reaction of CuCl[subscript…

Faraj, Santiago Enrique; Rossi, Rolando Carlos; Montes, Mónica Raquel – Journal of Biological Education, 2021
This report describes the implementation of a laboratory exercise for an advanced biochemistry or enzyme kinetics class at the undergraduate or graduate level, designed to improve understanding of protein conformational changes associated with the binding of a ligand. Students measure the fluorescence changes induced by the conformational…

He, Zhiyu; Ding, Shansen; Wang, Luyang; Wang, Guoqing; Liang, Xingguo; Takarada, Tohru; Maeda, Mizuo – Journal of Chemical Education, 2021
Demonstration of a colorimetric approach for nucleic acid detection represents an attractive educational experiment for chemistry undergraduate students in the time of coronavirus pandemic. Herein, a rapid and vivid detection method that visualizes the presence of a specific DNA sequence is described. The plasmon resonance of gold nanoparticles…

Ekin, Sabit; O'Hara, John F.; Turgut, Emrah; Colston, Nicole; Young, Jeffrey L. – IEEE Transactions on Education, 2021
Contribution: A do-it-yourself (DIY) light wave sensing (LWS) and communication project was developed to generate interest and clarify basic electromagnetic (EM) and wireless sensing/communication concepts among students at different education levels from middle school to undergraduate. This article demonstrates the nature of the project and its…

Lewohl, Joanne M. – International Journal of Educational Technology in Higher Education, 2023
The current cohort of undergraduate students is often said to value technology and is assumed to prefer immersive, interactive, and personalized learning experiences. In contrast, many educators recognise the value of face-to-face classes and believe that attending class positively impacts student performance. A novel teaching strategy, including…

Bahng, E. J.; Hauptman, John; Lowery, Jennifer – Journal of College Science Teaching, 2023
This article describes and illustrates a physics course for first-year college students whose only knowledge of physics is that they do not like the subject. The physics content is driven entirely by what appears in the daily newspapers and generally covers most physics topics in a semester. This course was structured as a learning community that…

Cavagnetto, Andy R.; Premo, Joshua; Coleman, Zachary; Juergens, Kate – CBE - Life Sciences Education, 2022
Small-group discussion is a central component of 21st-century biology classrooms. Many factors shape these discussions and thus influence potential learning gains. This study examined how accuracy and idea consideration shaped small-group discussions in undergraduate biology labs (12 groups, M = 42.8 talk turns). To do this, we asked: (1) Is there…

Erdogan, Sukran; Bozkurt, Ersin – Pegem Journal of Education and Instruction, 2022
The purpose of this study is to investigate the effect of teaching through a virtual laboratory prepared using simulations teaching materials and that are based on constructivist thought about geometrical optics upon the students' academic success and their attitudes towards physics. Quasi-experimental pretest and posttest control groups was used…

Çingil Baris, Çigdem – Biochemistry and Molecular Biology Education, 2022
Along with the COVID-19 pandemic, universities in Turkey as well as all over the world have started to carry out their education activities with the distance education method. In this case, many difficulties were encountered in the application of the Biology course, which is one of the applied courses carried out in the laboratory. Virtual…

Acuña-Girault, Adalberto; Gómez del Campo-Rábago, Ximena; Contreras-Ruiz, Marco Antonio; Ibanez, Jorge G. – Journal of Technology and Science Education, 2022
During the SARS-2-COVID pandemic our institution sought to continue the teaching and learning of experimental laboratories by designing, assembling, and delivering a microscale chemistry kit to the students' homes. Thanks to this approach students were able to perform [approximately]25 experiments during each one of the Fall 2020 and Spring 2021…
