engineers. Spirit AeroSystems will become morerecognized as a as a Global Integrator. They will also gain access to new anddifferent ideas with access to an unused resource pool. There is also the potentialof cost savings by resolving “engineering challenges” that may be solved with theinflux of new and diverse talent. Both industry and academia benefit bydeveloping key relationships on a global scale. As more engineers are neededwith global collaborative skills, efforts like the SDGC can develop engineers toface the needs of today’s (and tomorrow’s) industry.References1. Whitman, L.E., Malzahn, D.

inputbus and an 8-bit output bus. Input was assumed to be twelve 8-bit values comprising a matrix,A, and the computed output are the nine values comprising a matrix B where B=ATA . Whilethis seems fairly simple computationally, students were given performance specifications thatincluded an initiation rate of 15 clock cycles and a latency of 23 clock cycles. This means thatevery 15 clock cycles, a new set of matrix A values is present and that after 23 clock cycles fromthe beginning of the input matrix A values, the output values must be produced. Clearly, there isnot enough time to load all twelve input values, then perform the computation, followed byoutputting the resultant nine values; thus students must use overlapped computation.Furthermore a

The two factors that were found to be significant were (a) the student's gradein the Electric Circuits II lecture course and (b) the student's active participation as a “builder-tester”during the weekly laboratory exercises. The only factor that significantly and independently contributedto the students laboratory skills and knowledge base was the latter. The results of this study indicate thatstudents must be fully engaged in the fundamental laboratory exercises to thoroughly and properly learnthe skill and knowledge required to apply them in basic circuit analysis applications.BackgroundThe Electrical Circuits Lab course at Arkansas Tech University is an introductory laboratory

Often, these processes are presented as a means of finding asolution for a specific form of an equation. An interesting study occurs for students when theyare challenged to apply different problem solving techniques to the same equation.

statistics and the box plots support the notion that there are little to nodifferences for the freshman, sophomore or junior years in the DIT-2 scores. There is, however, adecided increase in the scores for seniors. The Gilbane Gold essay instrument did detectimprovements overall in ethical reasoning from freshman to senior years. Though we did nothypothesize a “senior” effect, its presence, if confirmed and examined further in future research,is interesting. Possible explanations for a senior effect are (a) the cumulative effect of four yearsof college, (b) increasing identification with one’s profession as education proceeds from generaleducation to degree-specific courses, or (c) “sudden” maturation as the student realizes thathe/she will soon be

In this paper we discuss a new approach to teaching problem solving and criticalthinking skills to physics and engineering physics students. We propose a new method in whichphysics students are asked to evaluate different solutions to a given problem and decide why aparticular solution is the correct one compared to various other approaches leading to the exactlysame final answer. This technique could facilitate critical thinking in students taking introductoryphysics courses.IntroductionPhysics is traditionally considered a difficult subject to master because of the high degree ofproblem solving skills demanded in learning the subject.
