load current and rapid decreases in speed disable the H2 drive for 90 s. The process of designing/constructing a drive to replace the H2 started Fall 2012; thisdrive will operate with a 380 V bus voltage while supplying 160 A for 20 s and 220 A for 3 s.Currently, a 1st generation BEV motor drive has been successfully tested with a 100 V bus.Tests conducted at a 380 V bus voltage have shown limited success; unexpected heating hasoccurred, leading to thermal runaway. Plans have been made to address this issue with a new380 to 18 V DC/DC converter needed for IGBT drivers and adding liquid cooling. This project built a bridge between local business and UAFS in motor development andspecialized powertrain parts as ABB Baldor has
globally competent engineer as one who “work[s] effectively with people whodefine problems differently than they do” (p. 110).8 Moreover, we understand navigating acrosscultures to be a salient characteristic of working effectively with those “who define problemsdifferently.” We understand culture to be “dominant images” (p. 5),9 a framework also proposedby Downey and Lucena.10 Lucena nicely articulates this understanding of culture: “[I]ndividualsliving and working in a particular spatial and temporal location are challenged by dominantimages. Dominant images create expectations about how individuals in that location aresupposed to act or behave. In this … concept of culture, the image remains the same over aperiod of time, while individual or

. Page 21.48.2BackgroundThe authors have conducted several studies investigating the impact of technology assistedcollaborative learning activities 8-12. Our findings highlighted the need to develop activitiesthat cultivate students‟ judgement, facilitate peer feedback, promote learner independence,and reinforce development of their professional engineering identity.Our aim is to promote a learning focus as opposed to a task-focused disposition in students.A student‟s core identity may be such that they resist this change in focus limiting theirengagement with these activities. We found scaffolding to be valuable to motivate desiredapproaches, behavior and attitudes to learning.For example, we constantly remind studentsthat “mistakes compress

Expectations for the Masters-Level Structural Engineering Graduate Preparedness using the Delphi MethodIntroduction Structural engineering educational programs in the U.S. are facing great challenges incorrelating their programs and goals with the needs of their graduates and the structuralengineering profession in today‟s constantly changing global environment. The ASCE Raise theBar initiative within civil engineering, its call for education beyond the undergraduate level forfuture entry into civil engineering practice, and ongoing and upcoming changes in professionalregistration emphasizes the need for structural engineering at the graduate level to be carefullyplanned.

Onesection of the semi-structured interview that will be of focus in this particular study askedparticipants to describe and rate the value placed on specific social support. On a 10-pointLikert scale ranging from 1-10, participants are asked to rate the value placed on theeducational and career support from family, classmates, friends, and engineering faculty.Participants were also asked whether these groups provided support, and if so, what types ofsupport(s) they received.ResultsQuantitative Analysis: Survey Black and Hispanic engineering students‘ responses on the Engineering Fields Surveyprovided quantitative data to examine students‘ perceptions of social support and barriers
innovative STEM educationprograms designed in part to increase student attitudes toward STEM subjects and careers. Thispaper describes how a team of researchers at The Friday Institute for Educational Innovation atNorth Carolina State University developed the Upper Elementary School and Middle/HighSchool Student Attitudes toward STEM (S-STEM) Surveys to measure those attitudes. Thesurveys each consist of four, validated constructs which use Likert-scale items to measurestudent attitudes toward science, mathematics, engineering and technology, 21st century skills.The surveys also contain a comprehensive section measuring student interest in STEM careers.The surveys have been administered to over 10,000 fourth through twelfth grade students inNorth

engineering positions.ResultsP1’s Mental ModelThe concept map representation of P1’s mental model is shown in Figure 1. The focus of P1’smodel of voltage and current is through the mathematical relationship, V = I * R (where V =voltage, I = current, and R = resistance), or its permutation, I = V / R. The three variables in theequation are treated as mathematical quantities, with no direct reference to anything physical.Thus, in the first equation, when V changes, I must change proportionately; but in the secondequation, if I increases, then V must increase and R must decrease. P1 states that this only workssome of the time, but P1 does not know what to do when it does not. The terms “voltage” and“current” are often used together, with the idea that

maintain a semester-long term project that examines real environmentalproblems, which our student teams (3-4 students of varying academic majors) observe or clients(such as the Department of Public Works or our student government) identify. Preparation forthe project requires student teams to develop a hypothesis and a basic sampling and evaluationprotocol. Students then use the protocol to conduct sampling in the local community and analyzeresults in light of their hypothesis. Students are required to submit a final written report. Thisterm project model also encourages interdisciplinary collaboration with non-STEM disciplines,such as the Marketing course in USMA‟s Department of Behavioral Sciences and Leadership.This cross-cutting educational

What applications, tools and methods truly enhance the learning environmentand what educational benefit, if any, do the students receive through the use of these devices?How do we integrate these devices in a way that appeals to our students, Prensky‟s “digitalnatives”4, when most of our professors are “digital immigrants”, without placing unmanageableburdens on the instructional team? The current literature examines the use of tablet devices in the college classroom but nostudy focuses on the use of iPads in the engineering classroom. An
