Network structures have strong effects on the frequency and terms of negotiated exchanges, shaping who exchanges with whom and who fares better or worse. In this study we ask how exchange patterns of commitment and inequality are affected when negotiated exchanges are combined with reciprocal exchanges in more complex relationships 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…

Teerasong, Saowapak; McClain, Robert L. – Journal of Chemical Education, 2011
We have developed an undergraduate laboratory activity to introduce students to microfluidics. In the activity, each student constructs their own microfluidic device using simple photolithographic techniques and then uses the device to separate a food dye mixture by electrophoresis. Dyes are used so that students are able to visually observe the…

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…

Sims, Paul A.; O'Mealey, Gary B.; Khan, Nabeel A.; Larabee, Chelsea M. – Journal of Chemical Education, 2011
A design for a simple and inexpensive gradient maker is described. The gradient maker is assembled by (i) cutting the tops off two plastic bottles of differing diameters to produce two cylinders with intact bottoms; (ii) drilling a small hole toward the bottom of the smaller diameter cylinder and plugging the hole with a size 00 cork stopper; and…

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…

Saribas, Deniz; Ceyhan, Gaye Defne – International Journal of STEM Education, 2015
Background: This auto-ethnographic study describes research conducted in a science teacher education program at a state university in Turkey, where I had taught the 'laboratory applications' course for the four previous years. While the students learned the basic skills needed to implement a laboratory course, I detected some deficiencies in their…

Galloway, Kelli R.; Bretz, Stacey Lowery – Journal of Chemical Education, 2015
Research on laboratory learning points to the need to better understand what and how students learn in the undergraduate chemistry laboratory. The Meaningful Learning in the Laboratory Instrument (MLLI) was administered to general and organic chemistry students from 15 colleges and universities across the United States in order to measure the…

Rubin, Samuel J.; Abrams, Binyomin – Journal of Chemical Education, 2015
Despite their technological savvy, most students entering university lack the necessary computer skills to succeed in a quantitative analysis course, in which they are often expected to input, analyze, and plot results of experiments without any previous formal education in Microsoft Excel or similar programs. This lack of formal education results…

The purpose of this exploratory, experimental study was to determine the effects that the type of reflection-in-action and students' cognitive style had on content knowledge of preservice agriculture teachers (N = 57) at Oklahoma State University. Students' cognitive style was assessed using Kirton's Adaptation-Innovation Inventory (KAI). Students…

Puig-Ortiz, Joan; Pàmies-Vilà, Rosa; Martinez Miralles, Jordi Ramon – Journal of Technology and Science Education, 2015
The following is a proposal for collaboration between universities with the aim to improve curricula that require laboratory activities. A methodology is suggested to implement an innovative educational project involving the exchange of laboratory activities. The exchange of laboratory activities can be carried out on different levels of…

Swan, Bonnie; Coulombe-Quach, Xuan-Lise; Huang, Angela; Godek, Jaime; Becker, Deborah; Zhou, Yan – Journal of Advanced Academics, 2015
Researchers used case study methods to investigate a virtual learning lab (VLL) in a rural school district that was created in 2011 as a way to better meet the unique needs of exceptional students who are considered gifted. Data were collected through focus groups, classroom observations, interviews, and reviewing relevant documents. Topics…

King, Donna; Ritchie, Stephen; Sandhu, Maryam; Henderson, Senka – International Journal of Science Education, 2015
Science activities that evoke positive emotional responses make a difference to students' emotional experience of science. In this study, we explored 8th Grade students' discrete emotions expressed during science activities in a unit on Energy. Multiple data sources including classroom videos, interviews and emotion diaries completed at the end of…
