ThermoNet’s home page and thenavigational scheme were designed based on interface design literature5 and enhanced based onstudents’ feedback during the prototype stage. It was determined that it was essential forstudents to have access not only to the tutorials through the home page, but also to the exampleproblems, tables, resources, supplemental links, and a site map.

between problem solving style as measured bythe KAI and any measure of cognitive level (such as intelligence quotient)8. In general, thecreativity which all people possess can be measured in two independent ways. We can measurecreative level by asking the question ‘How creative are you?’, and we can measure creative styleby asking ‘How are you creative?’. Adaption-Innovation Theory provides us with an explicitway to answer this second question.In AI Theory, the differences in cognitive style lie along a normally distributed continuum,which ranges from strong adaption on one end to strong innovation on the other6,7, as shownbelow in Figure 1. The fundamental distinction between the styles can be described in terms ofan individual’s preferred

The userenters rated horsepower, service factor, and the shaft speeds where the pulleys will be mounted.This is basic initial information a designer would be using if working with a belt drive. In orderto enter a service factor, the user clicks on the Service Factor Command button shown below,which opens the service factor form2.

OVERTURE: INTRODUCTION1.1 Motivation:Engineering education is transforming from a theoretical emphasis to a balance between appliedmathematics and science material and hands-on activities. Design components in courses arehelping to provide this balance. Instead of relegating design courses to the last two semesters ofan engineering program, many universities are spreading the experiences across the entire 4-5year curriculum.An example of this distribution of design courses is shown in Figure 1.

RP technologies like Stereolithography (SLA), Selective Laser Sintering(SLS), and Fused Deposition Modeling (FDM) deposit thermoplastic powders or resins in thinlayers to construct the model1. Designs for small parts can go from a CAD file to an actualmodel in just a few hours. The Engineering Technology department at Western WashingtonUniversity recently completed a solid modeling lab and purchased rapid prototyping equipmentwith a Concurrent Engineering Grant from an industrial partner.

Forexample, the ‘ability to work on multi-disciplinary teams’ may be assessed through: (1) thestudent’s self assessment of their enjoyment for working on teams via closed-formquestionnaires, (2) ratings by a student’s peers on the team, or (3) the direct observation of ateam by a trained evaluator. Triangulation may also involve using similar metrics across two ormore institutions so that results may be compared.

For this reason,the Piping Models course begins with an overview of MicroStation 3D capabilities andtechniques. The students are assigned separate portions of a complex, 3D piping system,to be modeled using basic MicroStation techniques. The individual sections are thencombined into an overall, unified model. Combining separately modeled piping into anintegrated system quickly reveals the importance of direction and position in space.Figure 1 is an integrated MicroStation model, which was formed by the combination ofseven separate pipe models.

We propose spending less time on the transforms themselves and more time at thebeginning of the course in presenting a finite-dimensional vector space framework. The DFT thenbecomes a natural application of this framework: the projection of a signal onto a complex expo-nential basis. The remaining three transforms follow with the same interpretation, differing onlyin the domain of application. Thus, students are presented with a rigorous but tractable develop-ment (the DFT) that supports all four transforms with a common foundation.1.
