Traditional experimental paradigms have focused on executing experiments in a lab setting and eventually moving successful findings to larger experiments in the field. However, data from field experiments can also be used to inform new lab experiments. Now, with the advent of large student populations using internet-based learning software, online…

Direct linkMallory, Cecile R. – ProQuest LLC, 2012
In the U.S., future economic viability is being challenged by an increasing inability to replace retiring engineers and scientists through the year 2020 due to declines in learner motivation and proficiency in science. The expository laboratory appears to be linked with non-engagement and is one possible contributing factor to this problem…

Peer reviewedMacrakis, Kristie; Bell, Elizabeth K.; Perry, Dale L.; Sweeder, Ryan D. – Journal of Chemical Education, 2012
By modifying secret writing formulas uncovered from the archives of the East German Ministry of State Security (MfS or Stasi), a novel general chemistry secret writing laboratory was developed. The laboratory combines science and history that highlights several fundamental chemical principles related to the writing. These include catalysis, redox…

Loudon, Catherine; Davis-Berg, Elizabeth C.; Botz, Jason T. – Advances in Physiology Education, 2012
A physical model was used in a laboratory exercise to teach students about countercurrent exchange mechanisms. Countercurrent exchange is the transport of heat or chemicals between fluids moving in opposite directions separated by a permeable barrier (such as blood within adjacent blood vessels flowing in opposite directions). Greater exchange of…

Sattar, Simeen – Journal of Chemical Education, 2011
Tris(1,10-phenanthroline)iron(II) is the basis of a suite of four experiments spanning 5 weeks. Students determine the rate law, activation energy, and equilibrium constant for the dissociation of the complex ion in acid solution and base dissociation constant for phenanthroline. The focus on one chemical system simplifies a daunting set of…

Liao, Wayne C.; Lien, Ching-Yi – Journal of Chemical Education, 2011
This experiment is designed to teach entry-level, nonchemistry-major students some basic organic chemistry through the procedure for making cosmetics. The experiment combines facial toner preparation with distillation techniques to create a stimulating learning environment. During the experiment, students perform a distillation to collect some…

Precup, R.-E.; Preitl, S.; Radac, M.-B.; Petriu, E. M.; Dragos, C.-A.; Tar, J. K. – IEEE Transactions on Education, 2011
This paper discusses an experiment-based approach to teaching an advanced control engineering syllabus involving controlled plant analysis and modeling, control structures and algorithms, real-time laboratory experiments, and their assessment. These experiments are structured around the representative case of the longitudinal slip control of an…

Bennett, Jacqueline; Pence, Harry E. – Journal of Chemical Education, 2011
One of the most significant difficulties encountered when directing undergraduate research and developing new laboratory experiments is how to efficiently manage the data generated by a number of students. Cloud computing, where both software and computer files reside online, offers a solution to this data-management problem and allows researchers…

Bonanno, A.; Bozzo, G.; Camarca, M.; Sapia, P. – Physics Education, 2011
In this article we describe an experimental learning path about electromagnetic induction which uses an Atwood machine where one of the two hanging bodies is a cylindrical magnet falling through a plexiglass guide, surrounded either by a coil or by a copper pipe. The first configuration (magnet falling across a coil) allows students to…

Drummond, Gordon B.; Vowler, Sarah L. – Advances in Physiology Education, 2011
Current standards of data presentation and analysis in biological journals often fall short of ideal. This is the first of a planned series of short articles, to be published in a number of journals, aiming to highlight the principles of clear data presentation and appropriate statistical analysis. This article considers the methods used to show…

Cloonan, Carrie A.; Andrew, Julie A.; Nichol, Carolyn A.; Hutchinson, John S. – Journal of Chemical Education, 2011
This article describes an activity that can be used as an inquiry-based laboratory or demonstration for either high school or undergraduate chemistry students to provide a basis for understanding both vapor pressure and the concept of dynamic phase equilibrium. The activity includes a simple setup to create a closed system of only water liquid and…

Ling, Chris D.; Bridgeman, Adam J. – Journal of Chemical Education, 2011
Titration experiments are ideal for generating large data sets for use in quantitative-analysis activities that are meaningful and transparent to general chemistry students. We report the successful implementation of a sophisticated quantitative exercise in which the students identify a series of unknown acids by determining their molar masses…

Bailey, James A. – Journal of Chemical Education, 2011
Although there are numerous inorganic model systems that are readily presented as undergraduate laboratory experiments in bioinorganic chemistry, there are few examples that explore the inorganic chemistry of actual biological molecules. We present a laboratory experiment using the oxygen-binding protein myoglobin that can be easily incorporated…

Clark, William M.; Jackson, Yaminah Z.; Morin, Michael T.; Ferraro, Giacomo P. – Chemical Engineering Education, 2011
Laboratory experiments and computer models for studying the mass transfer process of removing CO2 from air using water or dilute NaOH solution as absorbent are presented. Models tie experiment to theory and give a visual representation of concentration profiles and also illustrate the two-film theory and the relative importance of various…
