The case study is about digitization and replication of ahistorical plaster pattern of Robert Morris (Figure 1), one of the founders of the United States ofAmerica. Details of the scanning stages (Figure 2) and engineering solutions developed forsuccessful digitization such as fabrication of a rotary table and its introduction to the Geomagicscanning software are introduced within the study. The three rapid prototyping technologies thatproduced copies of the original piece are also discussed in detail (two of which are shown inFigure 3). Subsequently, the use of Room Temperature Vulcanization (RTV) molds to castpolyurethane copies is

The microcontroller and CodeWarrior IDE arecovered in a number of references[1], [2], [7], [8], [11], [15] and [16]. The microcontroller and CodeWarriorIDE are available as a kit offered by Freescale Semiconductors. Individual modules are alsoavailable from other vendors. The kit contains a project board for flashing the microcontrollerand for electronic circuit prototyping. The kits were first used in our linear control systemscourse in fall 2006.The rest of this paper is organized as follows: Section II covers briefly the pedagogical approachfor the course.

While research outcomes are not entirelyconsistent on this point, evidence is that the gender and racial gap in persistence onceenrolled in an engineering major has narrowed to near parity. In a recent analysis, forexample, Lord et al.1 determined that contrary to prevailing perceptions, women and menpersist in engineering majors at approximately the same rate across all ethnic groups.Less encouraging is evidence that a gender gap persists after completion of anundergraduate major in engineering, when women were significantly less likely than mento express interest in pursuing jobs in engineering2,3,4.Conceptual FrameworkThe literature

Recently, leaders in manufacturing educationhave been working on the recommended curricula, so called Curricula 2015 [1].According to the paper published in 2009 ASEE conference [1], bio-productmanufacturing was chosen as a new discipline that the educators should focus on. Forbio-product manufacturing or biomanufacturing, a unified definition is definitely lacking.Often, biomanufacturing deals with the production of pharmaceuticals and agriculturalproducts [2], which is mainly a subject under the disciplines of

education is to prepare students for engineering in the 21stcentury. Yet critics of engineering education point to the lack of preparation students obtain inschool. This paper examines the career supports and barriers that one cohort of recentengineering graduates experienced in the workplace. Social Cognitive Career Theory (SCCT)describes supports and barriers as environmental factors that individuals perceive as having thepotential to either aid or hinder their pursuit of a particular career goal.1 In this study, supportsand barriers are identified in the engineering departments of four U.S.-based companies. Thedata were gathered from semi-structured interviews with 59 newly hired engineers who hadrecently graduated from college. In two of the

However, thereremains much to be done. The U.S. educational system is not currently developing theexcellent grounding in science that is needed in the United States to remain competitivein this global economy.

Introduction One of the most difficult concepts for students in an undergraduate dynamics course isthat of rigid body kinematics. The geometry of rigid body motion, a topic most students arefamiliar with from undergraduate physics, takes on additional complexity as one introducesangular velocities and accelerations of rigid bodies. Couple this with the fact that the majority ofstudents in an undergraduate dynamics course just completed an undergraduate statics coursefree of motion, and the result is clouded confusion and inability to understand what is reallyhappening to the rigid body.

Anecdotally, seeing little improvement inthe final examination grades (shown in Table 1) led us simply to drop the graded homeworkrequirement in summer 2008 and spring 2009 semesters. We still assigned the homeworkproblems but did not collect them for grade. However, we posted solutions to the multiple-choicetest problems, which comprised of about 50% of the assigned problems, and used personalresponse systems in the classroom for reviewing pre-requisite knowledge and checking end-of-topic knowledge through sets of 5-10 multiple-choice questions.
