educational side, it was easy to integrate the course projects into our classes because ofour previous commitment to include service learning as part of the curriculum. The servicelearning projects also provide the students an appreciation for the importance of being part oftheir community, which they will hopefully continue throughout their professional careers.However, except for the student interns, one shortcoming was that the course projects were notdone by multidiscipline teams. Each project was worked on either by art, architect, orengineering students who were enrolled in that particular class. These projects were done inparallel with very little integration. The only integration was when the art and architecturestudents met together and the

During the 1980’s, the SloanFoundation’s New Liberal Arts Initiative made grants totaling $20 million in order to develop aset of courses that integrate technical and quantitative literacy into traditional liberal arts studies[5].Many small liberal arts colleges have tried to offer an engineering option through the adoption of3-2 programs [6]. Experience has shown, however, that very few students ultimately pursue the3-2 route for a number of reasonsfor instance, they want to continue participating in athleticsor they want to graduate with their friends. Other colleges have added engineering majors. Forinstance, Hope College in Michigan added

Virtualproduct data management systems that integrate manufacturing data are immerging thattheoretically allow for the seamless exchange of data between OEMs and tier suppliers. Thesetechnologies represent the application side of PLM and are also in their formative stages. Thegoal of PLM’s supply chain management process is to produce a concurrent and contextualenvironment where data is not pushed to sub-tier supplies but is always available (IBM, 2001).Included within this is the reutilization of existing components within new designs (Farrant,2001).

Integrating Traditional Circuit Analysis and Circuit Analysis Emphasizing Signal Processing ConceptsAn example of integrating traditional circuit analysis and a signal processing approachcan be illustrated in the use of the voltage divider rule. A traditional circuit analysiscourse typically demonstrates how the voltage divider rule can be used to determine thevoltage at any point in a series configuration as illustrated in Figure 3

The student performance is graded based on several factors such as: theability to extract the key technical concept of the paper, the technical knowledge of the subjectmatter, proficiency and confidence in presenting, and the quality of the written report.

Furthermore, instructors can easily provide a wide variety of experiences for students with aminimal amount of incremental course refinements.1 Introduction One of the many challenges facing engineering educators today is the need to keep pace withtechnological advancements. Many factors must be considered before integrating new technologyinto a curriculum. Traditionally, if the technology varies widely from technology in current courseofferings, a new course is considered. Otherwise, an existing course is modified or updated. Ineither case, the process of integrating the new technology into a curriculum can be both expensiveand time consuming. Product Line and Product Family

K-12 outreach has alsobeen an exciting component of the DIT project. The colors and numbers module is very wellreceived by middle school girls. Currently two more modules are still being developed in thearea of nanotechnology and thermodynamics.
