It also shows qualitative assessment data that support following conclusions: 1) studentstook more ownership of their duties on the project through involvement in planning andmodules; 2) students implemented project scheduling and monitoring to their capstone projects,effectively beginning to develop related skills; and 3) faculty advisors were for most partfocusing only on the technical parts of the project, effectively leaving the management tostudents and a few in-class workshops. The paper also offers suggestions on how to motivateand train the students and faculty for future years.IntroductionAt Seattle University all engineering seniors are required to participate in a three quartercapstone senior design
student’s development over time.IntroductionResearch has shown that identifying with engineering contributes positively to students’persistence in earning an engineering degree.1, 2 While some students may enter engineeringprograms with the belief that he or she is “an engineering-type person,” this is not true for allstudents.3 Therefore, engineering educators and administrators need ways to encourage students’engineering identity development. However, current research lacks a clear understanding of howstudents’ develop identification with engineering and what universities can do to enhancestudents’ identification with the profession.To begin closing this gap, we designed a multi-institution study that enabled us to examine andcompare a military

Page 22.70.2Research QuestionsThe research questions in this study are: 1) How do prediction performances of multi-outcome model compare with those of individual single-outcome models? 2) Do the important predictors identified by the multi-outcome models align with those identified by single-outcome models? 3) Are the important predictors of first-year retention the same as those of first-year GPA?Modeling Student Success in EngineeringFigure 1 shows the framework of our model of student success. The predictors, listed at the leftin the figure, can be grouped into two categories: the affective measures and the high schoolhistory matrix. Affective measures include nine factors: expectancy, leadership, meta-cognition,major

The teams were multidisciplinary but there was little interdisciplinary interaction.Around 6 years ago, in 2004, standardization of the design practices was implementedand multidisciplinary interaction increased slightly. In 2005, further improvements weremade to the project that required more interdisciplinary design and testing effort. 4 Whilethese changes were effective, the mechanical engineering faculty involved with theproject deemed the required effort to be high for the 1 credit course. Subsequent surveydata showed that the level of interdisciplinary interaction decreased after the additionalrequirements were not

Introduction Transportation engineering workforce development at the university level is commonlypromoted through civil engineering programs. Nearly all of the nation’s 224 civil engineeringprograms have one or two required transportation courses as part of their undergraduateprogram.1 For some civil engineering sub-disciplines, such as geotechnical, materials, structures,and hydraulics, a logical sequence of required prerequisite courses leads to the required courses.For other disciplines, such as transportation, the logic and sequence is less clear. A lack of clarityand connection with other sub-disciplines pose significant challenges for faculty, students

The student assembles theelectronic devices on the breadboard. The breadboard provides a simple mechanism toelectrically interconnect the electronic devices. The top surface of the breadboard has 22 AWGgauge holes to insert the pins of the electronic device. The holes are referred to as contact pointsor tie points. Underneath the surface of the breadboard are strips of metal that form an electricalnode. The metal strip has spring clips that hold the inserted wire in place. The spacing betweenholes is 2.54 mm or 0.1 inch. The node can be extended by daisy chaining 22 AWG wire to

These calls stem from concerns that the typical engineering curricula are notproviding students with experiences that enable them to acquire the competencies andprofessionalism required by the profession in the global 21st century. 1, 2 To address theseconcerns, some educators advocate for a more holistic curriculum and more practical experiencesthat can enhance student engagement and better prepare them for professional practice. 1 Otherspropose increasing the social interaction and development of students via collaborative,integrative learning experiences that allow them to develop a deeper understanding ofengineering and enhance their
valuable for learning Statics.IntroductionIntelligent tutoring systems have long been a focus of research, with applications spanninga wide range of subjects such as computer programming,1 law,2 medicine,3 physics,4 andStatics.5 Most current systems rely on traditional WIMP (Windows, Icons, Menus,Pointer) user interfaces. While such interfaces may be useful in some domains, they haveclear limitations. For example, they are typically not well-suited for instruction in domainsin which solutions require complex graphics. Engineering Statics is one such domain.Solving Statics problems requires the construction of free body diagrams and equilibriumequations, two tasks which are difficult to perform with a mouse and keyboard.Here we present our efforts
potential of the available tools throughout all of the formative phases of thecurriculum. Based on evidence from experience, we advocate for a new, consistent approach ofearly and continued exposure to FEA, beginning with the freshmen year, and continuing withsubsequent mechanics courses, in which students can learn and interpret results of FEA, withoutrequiring deep instruction in the underlying FE theory. We further argue that this concurrentFEA usage will improve students‟ understanding of mechanics theory and practice. We hope thatthis paper may provide a foundation and justification for considering the use of professionalsoftware in engineering education.1.

defined as the ability to easily be moved or carried1. A key component of manymilitary systems is their ability to be quickly assembled/disassembled, moved to differentlocations, and to use minimum manpower and equipment in order to accomplish the mission.One problem in redesigning systems to increase portability is that there is not currently anestablished rubric for measuring portability. The portability of a system is a function of severaldifferent aspects. We have developed a rubric to measure a system’s portability. The rubricincludes 18 parameters (Table 1) as discussed in detail below.In order to use the rubric, each of the 18 portability measures identified above is quantified forthe system(s) being evaluated. This information can then be

The open-source datamining tool, RapidMiner, is introduced to assist students to explore and digest variousdata mining processes and algorithms. Overall, the hands-on experience provides studentsa better insight into data mining functions.1.

Statistical analysis and data miningtechniques have emerged for these purposes. Data mining is the process of discoveringpreviously

design activity is a complexand methodology-based task which requires the student to follow specified processes and usestrategies. Consequently, research on metacognition in engineering design activity tends to applya mixed-methods approach because of the complex nature of the field.Interviews, most often used in qualitative-based research, are also valuable in a mixed-methodstudy. Interviews provide researchers an opportunity to confirm collected data from other data-collection techniques with the study participants.

On the first evening of class the students are shown the instructor's first-generation iPod,which has no external volume control. We connect the iPod to external speakers (e.g., those for adesktop computer) and draw the connections on the board. The instructor then takes a stick ofgraphite and draws heavy streak (~1-inch-wide and ~6-inches-long) down a sheet of paper. TheiPod output is connected across the ends of the streak. One speaker lead is attached to one end ofthe graphite streak, while the other is slid along the graphite, causing the sound level of thespeaker to rise and fall (Figure 1). These connections are then sketched on the board, andstudents (typically

In order to effectively demonstrate this program, many testsusing different variable types had been run to show the accuracy and repeatability of the robotthrough offsets6-13. This test is very useful for calibrating the robot on an Internet basis and beingable to record data in real-time without having to be in the same location as the robot or theMP2000 Readout Controller. Furthermore, it helps with the improvement of Internet-basedcontrols with the Yamaha Robot (Figure 1).
