the pilot plant), and review of literature (multidisciplinary in nature). Two researchers acted as "clients", providing a charge to each team with a request for design recommendations. The charge memo provided a very open-ended design task (this is the second design course; the first is a much more traditional chemical engineering process design experience). b. Each team needed to work on a tight schedule to produce recommendations for the "client". While chemical engineering issues were the primary focus of the team's work, the context of the design challenge required understanding of multidisciplinary issues

Finally, some demonstrations required pumps or other forms of moreexpensive/complicated lab equipment (for example, [9] - [11]), which would not be ideal for asimple demonstration during a lecture course.For this project, a fixed-bed adsorption demonstration was developed that is not only relativelylarge in size, is also very cheap, safe, and colorful. Furthermore, the demonstration could beeasily expanded to be a short lab activity that could be completed by student teams to examinethe effects of several key variables, such as bed height, contaminant concentration, etc.Construction details for the demonstration are provided in Appendix B.

Among students with a preference, active, sensing, visual, and sequential areconsistently predominant in the population, except in Spring 2014 where there is a nearly equalnumber of active and reflective students.In three particular instances, we observed a statistically significant difference (α = 0.05) instudent performance on an exam problem with respect to learning style. These instances occurredin the sensing/intuitive dimension (intuitors had lower scores), visual/verbal dimension (verballearners had lower scores), and the sequential/global
direction from the inside of the electrode to the outsideand the K+ gradient is in the opposite direction. After 10 min of calibration the di-ISE systemwill reach the Na+ and K+ ion concentration/electrical equilibrium resting potential as is for a Page 26.837.4living neuron before stimulation [11].Fig. 3 B shows how the sensor will react when the K+ ionophore side is blocked by a screw-actuated flexible cover. Blockade of the K+ flux allows fewer K+ ions to flow through themembrane than Na+ ions, i.e., only those carried by the low K+ selective NaX will cross on theNaX side. Hence, the voltage will change and move towards the Na+ equilibrium

the authors has developed an asynchronous software program for use in computer sciencecourses.

Studentssubmit code solutions to be reviewed through the system. Once they have done so, their solutionsbecome "locked": they may no longer modify them, but they now have access to the codesolutions of their peers. Thus, a period of on-line code review can begin. Students areencouraged to view the solutions of the members of their review team, to identify issues withthose solutions, and to log those
