Virtual laboratories are transformative tools in science education, yet comprehensive reviews of their prospects are limited. This study addresses this gap through a bibliometric analysis of 218 articles published between 2013 and 2023. Key findings included: (1) research has evolved from initial exploration to rapid expansion; (2) virtual labs…

Direct linkKrzic, Maja; Wilson, Julie; Hazlett, Paul; Diochon, Amanda – Natural Sciences Education, 2019
This study explored practices that Canadian soil scientists use to educate postsecondary students, K-12 students, and the general public. The most commonly used type of educational activities described by survey respondents, regardless of the settings and the type of target audience, were field-based hands-on activities. The other two commonly…

Australian and New Zealand universities commenced a new academic year in February/March 2020 largely with "business as usual." The subsequent Covid-19 pandemic imposed unexpected disruptions to anatomical educational practice. Rapid change occurred due to government-imposed physical distancing regulations from March 2020 that…

Undergraduate Laboratory Module for Implementing ELISA on the High Performance Microfluidic Platform
Giri, Basant; Peesara, Ravichander R.; Yanagisawa, Naoki; Dutta, Debashis – Journal of Chemical Education, 2015
Implementing enzyme-linked immunosorbent assays (ELISA) in microchannels offers several advantages over its traditional microtiter plate-based format, including a reduced sample volume requirement, shorter incubation period, and greater sensitivity. Moreover, microfluidic ELISA platforms are inexpensive to fabricate and allow integration of…

Morton, Janine G.; Joe, Candice L.; Stolla, Massiel C.; Koshland, Sophia R.; Londergan, Casey H.; Schofield, Mark H. – Journal of Chemical Education, 2015
Variable temperature NMR spectroscopy is used to determine the ?H° and ?S° of hydrogen bond formation in a simple diamide. In this two- or three-day experiment, students synthesize N,N'-dimethylmalonamide, dimethylsuccinamide, dimethylglutaramide, or dimethyladipamide from methylamine and the corresponding diester (typically in 50% recrystallized…

Via, Garrhett; Williams, Chelsey; Dudek, Raymond; Dudek, John – Journal of Chemical Education, 2015
First-order kinetic decay rates can be obtained by measuring the time-dependent reflection spectra of ultraviolet-sensitive objects as they returned from their excited, colored state back to the ground, colorless state. In this paper, a procedure is described which provides an innovative and unique twist on standard, undergraduate, kinetics…

El Seoud, Omar A.; Galgano, Paula D.; Are^as, Elizabeth P. G.; Moraes, Jamille M. – Journal of Chemical Education, 2015
The determination of kinetic data is central to reaction mechanism; science courses usually include experiments on chemical kinetics. Thanks to PC-controlled data acquisition and availability of software, the students calculate rate constants, whether the experiment has been done properly or not. This contrasts with their experience in, e.g.,…

Barth, Roger; Moran, Michael J. – Journal of Chemical Education, 2014
An improved procedure for laboratory determination of the heat capacities of metals is described. The temperature of cold water is continuously recorded with a computer-interfaced temperature probe and the room temperature metal is added. The method is more accurate and faster than previous methods. It allows students to get accurate measurements…

Gaynor, James D.; Wetterer, Anna M.; Cochran, Rea M.; Valente, Edward J.; Mayer, Steven G. – Journal of Chemical Education, 2015
Raman spectroscopy is a powerful experimental technique, yet it is often missing from the undergraduate physical chemistry laboratory curriculum. Tetrachloromethane (CCl[subscript 4]) is the ideal molecule for an introductory vibrational spectroscopy experiment and the symmetric stretch vibration contains fine structure due to isotopic variations…

van Hunnik, Eddy – Higher Learning Research Communications, 2015
Online education has been steadily growing during the last decade. This growth has mainly taken place in the non-laboratory science fields. This essay describes some of the best practices to increase and maintain student retention, increase student engagement and increase graduation rates for college running online laboratory science courses. This…

Bussie`re, Guillaume; Stoodley, Robin; Yajima, Kano; Bagai, Abhimanyu; Popowich, Aleksandra K.; Matthews, Nicholas E. – Journal of Chemical Education, 2014
Although vacuum technology is essential to many aspects of modern physical and analytical chemistry, vacuum experiments are rarely the focus of undergraduate laboratories. We describe an experiment that introduces students to vacuum science and mass spectrometry. The students first assemble a vacuum system, including a mass spectrometer. While…

de los Santos, Desiree´ M.; Montes, Antonio; Sa´nchez-Coronilla, Antonio; Navas, Javier – Journal of Chemical Education, 2014
A Project Based Learning (PBL) methodology was used in the practical laboratories of the Advanced Physical Chemistry department. The project type proposed simulates "real research" focusing on sol-gel synthesis and the application of the obtained sol as a stone consolidant. Students were divided into small groups (2 to 3 students) to…

Triona, Lara M.; Klahr, David – Science Education Review, 2007
Hands-on science typically uses physical materials to give students first-hand experience in scientific methodologies, but the recent availability of virtual laboratories raises an important question about whether what students' hands are on matters to their learning. The overall findings of two articles that employed simple comparisons of…

Wellington, Jerry, Ed. – 1998
This book attempts to reflect on the value and purpose of practical work as part of the science curriculum: why are practical exercises so necessary and what do they contribute to the science learning process? The chapters in this book examine issues such as: how practical work is perceived by students and teachers; the possibilities and perils of…
