Ying Zhang; Yuqin Yang; Yongkang Chu; Daner Sun; Jiazhen Xu; Yuhui Zheng – Journal of Baltic Science Education, 2024
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 linkDripps, Weston – Natural Sciences Education, 2019
In recent years there have been concerted efforts among water science educators to increase the number and quality of interactive classroom, field, and lab experiences in undergraduate water resource courses. This article reviews the transformation of a traditional lecture-based hydrology course with a global emphasis to a field-based, integrated…

Krzic, 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…

Levine, Lauren A.; Junker, Matthew; Stark, Myranda; Greenleaf, Dustin – Journal of Chemical Education, 2015
A simple and economical experimental setup is described that enables multiple individuals or groups within a laboratory class to measure the thermal melting of double stranded DNA simultaneously. The setup utilizes a basic spectrophotometer capable of measuring absorbance at 260 nm, UV plastic cuvettes, and a stirring hot plate. Students measure…

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…

Heldt, Caryn L.; Bank, Alex; Turpeinen, Dylan; King, Julia A. – Chemical Engineering Education, 2016
The need to increase science, technology, engineering, and mathematics (STEM) graduates is great. To interest more students into STEM degrees, we made our graphene biosensor research portable, inexpensive, and safe to demonstrate technology development to high school students. The students increased their knowledge of biosensors and proteins, and…

Mobley, T. Andrew – Journal of Chemical Education, 2015
A simple organic chemistry experiment is described that investigates the kinetics of the reaction between 1-bromobutane (BuBr) and iodide (I[superscript -]) as followed by observing the disappearance of BuBr and the appearance of 1-iodobutane (BuI) using [superscript 1]H NMR spectroscopy. In small groups of three to four, students acquire data to…

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.,…

A Stopped-Flow Kinetics Experiment for the Physical Chemistry Laboratory Using Noncorrosive Reagents
Prigodich, Richard V. – Journal of Chemical Education, 2014
Stopped-flow kinetics techniques are important to the study of rapid chemical and biochemical reactions. Incorporation of a stopped-flow kinetics experiment into the physical chemistry laboratory curriculum would therefore be an instructive addition. However, the usual reactions studied in such exercises employ a corrosive reagent that can over…

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…
