Fedick, Patrick Walter – ProQuest LLC, 2018
Ambient ionization mass spectrometry enables rapid in-situ analysis of a plethora of analytes that are relevant to the forensic and defense communities. As the arsenal of ambient ionization techniques, aimed at solving specific targeted problems, continues to expand, the adoption of these techniques into non-academic settings has been relatively…

Larsen, Molly C.; Perkins, Russell J. – Journal of Chemical Education, 2016
A low-cost, time-resolved spectroscopy experiment appropriate for third year physical chemistry students is presented. Students excite o-methyl red in basic solutions with a laser pointer and use a modular spectrometer with a CCD array detector to monitor the transient spectra as the higher-energy cis conformer of the molecule converts back to the…

Tapia-Pineda, Adabelia; Perez-Arrieta, Carlos; Silva-Cuevas, Carolina; Paleo, Ehecatl; Lujan-Montelongo, J. Armando – Journal of Chemical Education, 2016
A simple, microscale experiment was developed with the aim of demonstrating the concept of umpolung in synthetic organic chemistry. Starting from a common alkyl sulfinate, students perform a polarity inversion by performing a Grignard-based sulfoxide synthesis and a Mannich-type formamide synthesis. The products are purified without chromatography…

Yearty, Kasey L.; Sharp, Joseph T.; Meehan, Emma K.; Wallace, Doyle R.; Jackson, Douglas M.; Morrison, Richard W. – Journal of Chemical Education, 2017
[Superscript 1]H NMR analysis is an important analytical technique presented in introductory organic chemistry courses. NMR instrument access is limited for undergraduate organic chemistry students due to the size of the instrument, price of NMR solvents, and the maintenance level required for instrument upkeep. The University of Georgia Chemistry…

Elias, Ryan J.; Hopfer, Helene; Hofstaedter, Amanda N.; Hayes, John E. – Journal of Food Science Education, 2017
The human nose is a very sensitive detector and is able to detect potent aroma compounds down to low ng/L levels. These levels are often below detection limits of analytical instrumentation. The following laboratory exercise is designed to compare instrumental and human methods for the detection of volatile odor active compounds. Reference…

Lubrica, Joel V.; Abiasen, Jovalson T.; Dolipas, Bretel B.; Ramos, Jennifer Lyn S. – Physics Education, 2017
In this article, we present results of our endeavours as physics educators to facilitate and support pedagogical change and development in the educational system of a developing country, the Philippines. We have discovered that the interaction of junior high school (years 7-10) students with physics apparatus can influence students' interest in…

Oliveira, Ana; Wainman, Bruce; Palombella, Andrew; Rockarts, Jasmine; Wojkowski, Sarah – Anatomical Sciences Education, 2023
Interprofessional learning improves students' clinical and interprofessional competencies. COVID-19 prevented delivering in-person education and motivated the development of a virtual interprofessional cadaveric dissection (ICD) course. This study reports on the effects of a virtual ICD course compared to a previously delivered in-person course,…

Rahmani, Shams R.; Mashtare, Michael L.; Schulze, Darrell G.; Camberato, James J.; Johnston, Cliff T.; Fulk-Bringman, Sherry S. – Natural Sciences Education, 2023
Beginning abruptly in the second half of the Spring 2020 semester at Purdue University, we modified our teaching approach in Introductory Soil Science and Forest Soils courses (AGRY 255/270) with a combined annual enrollment of [approximately]370 students to cope with the COVID-19 pandemic. In that semester, we went to entirely virtual lecture,…

Kapici, Hasan Özgür; Costu, Fatma – Journal of Turkish Science Education, 2023
One of the main courses that have been affected by instructional technology is science education since the nature of topics covered by the science curriculum may require the usage of technology to teach them better. The aim of the current study was to investigate the effects of virtual laboratories on the development of gifted children's…

Bwalya, Tuesday – International Journal of Education and Development using Information and Communication Technology, 2023
For schools to successfully deliver the computer studies curriculum, they should have, among other things, qualified teachers and computer laboratories. This study investigated the availability of qualified computer studies teachers and computer laboratories in public secondary schools in Lusaka City, Zambia. A mixed-methods approach was employed…

Tuaputty, Hasan; Alimudi, Saiful; Irene, Ine; Latuperissa, L. N.; Donkor, Anthony Kudjo – Journal of Biological Education Indonesia (Jurnal Pendidikan Biologi Indonesia), 2023
The learning process must actively involve students and provide opportunities for them to study and prove the theories they learn. This study determined the influence of the application of Project-Besad Learning (PjBL) using a laboratory approach on learning outcomes and critical thinking in marine biology. This study used a descriptive…

Beth; Gallagher, Tiffany; Cavendish, Leslie; Milby, Tammy; Rogers, Rebecca; Johnson, Tracy; Msengi, Shadrack; Dozier, Cheryl; Huggins, Shelly; Gurvitz, Debra – Literacy Research and Instruction, 2023
The resiliency of literacy clinics was tested during 2020-2021, as many pivoted from in-person (F2F) to online or 3-way remote learning because of the COVID-19 pandemic. University-based literacy clinics advance teacher education, provide services to K-12 students who may need instructional support, and are a laboratory for research. The purpose…

Kácovský, Petr; Snetinová, M.; Chvál, M.; Houfková, J.; Koupilová, Z. – International Journal of Science Education, 2023
In this study, we focused on students' intrinsic motivation towards practical work, more specifically the strength of predictors for intrinsic motivation. As a research tool, we used a modified Intrinsic Motivation Inventory supplemented by additional questions on attitudes towards physics. The respondents were more than 2000 Czech upper secondary…
