In our global society, this has become more and more important but it remains difficult to measure.More and more, we are trying to understand our students and their abilities to learn in these fourcategories but measuring all but cognitive intelligence has remained allusive.8Generally, we know, after years of study of cognition, motivation and human development, thefollowing four key concepts that apply to college students: 1.

The claim of Writing Acrossthe Curriculum is that in order to write about a concept clearly you must have a goodunderstanding. In addition to the writing component, we are connecting the physics and calculuscourses that freshman take. Kumar and Jalko4 make the claim that mathematics courses shouldbe taught from an applications point of view. We also look to reinforce several efforts at Vaughn 1to improve retention rates of engineering students. Some of these efforts have included freshmanorientation courses, learning

Within this project, our laboratory has focused on the use of dedicated FieldProgrammable Gate Array (FPGA) hardware for computationally intensive algorithms. When images andvideo are acquired, some manipulation and processing must occur before they are displayed. In order tomaintain real-time feedback to the pilot, dedicated hardware can be used instead of software solutions.This article evaluates a design method for a real-time processing system based on Field Programmable GateArray (FPGA) and Digital Signal Processing (DSP) structure.

inTable 1. As shown, 84% of the total grade was assessed during scheduled class and laboratorytime. Since attendance was mandatory, few would miss any of the in-class graded events. Thisprompted a focus of short-term preparation since quizzes, exams and the term-ends were allscheduled events, while assignments were less emphasized because they were simple, time-demanding, worth few points and provided with solutions at a later time.To overcome this procrastination in this course, the author proposed two objectives: shift pointsfrom in-class to out-of-class events and reduce the total number of events. Later offerings ofEE302 in Spring 2008, 2009 and 2010 are used as the basis of comparison and effectiveness ofthe aforementioned adjustments. Some

thencasted in PDMS, yielding microfluidic devices with a height of ~ 60 µm—or multiples of 60 µm,if several layers of tape were stacked. This technology makes it possible to create microfluidicdevices with any planar (2D) design that the students can draw on a paper. After the drawing isfinished, it takes only 1 hour to fabricate a microfluidic device with the shape of that drawing.We believe that this technique will enable the study of microfluidics in educational settingslimited in their access to cleanroom facilities. We present a demonstrator that illustrates thepotential of this technique in standard teaching labs.IntroductionIn this paper, we describe a method to fabricate microfluidic devices using only bench-topmaterials and tools (Scotch

representing measureable properties of systems. The concept is anotational device for writing the laws of these systems. Consider the set of rectangles as oursystem to study. The laws are relationships of the system, in this case: 1) The area of any rectangle is the product of its length and width and 2) the perimeter is twice the sum of the length and width.Call the length, L, the width, W, the area, A and the perimeter, P. Then in algebraic notationthese laws become: 1) A = LW and 2) P = 2(L + W). This algebraic notation is a wonderfulinvention. Not only are laws written more compactly in algebraic notation, but the algebraicnotation is easily manipulated. The relationship, A = LW, can also be modified by the rules ofalgebra to L = A/W

The test group was given 2 separate but identical lectures, each with diagrams of construction details, and 1 short topic specific supplemental video per topic. Quizzes conducted in both groups showed that the test group scored higher on questions on these topics than the control group, and the difference in quiz scores between the 2 groups was statistically significant. These results suggest that topic specific videos are a valuable educational tool when accompanied by visual handouts. Key words: Assessment, SIPs and ICF, video-based learning

Mostcommercial PV products have efficiencies in the 10-15% range, significantly lessthan the 30% theoretical maximum predicted by Schockley. The PV industry hasbeen trying to achieve a cost of $1/Watt-peak for over 30 years and much ofcurrent industry activity is focused on low-cost PV technologies and reducingmanufacturing costs. Moreover, a large percentage of the installed PVinfrastructure can be attributed to significant subsidies and tax

Educators cancontrol this by being more proactive in the process of not only team assignments, but in teambuilding exercises. It is likely that, with diverse student teams, two benefits accrue: (1) moreinteresting approaches to problems, and (2) students graduate better prepared to work inenvironments where multicultural groups are more the norm.C.
