Theresults of this initial change showed marked improvement in the student’s scores on the first quizand exam of the microelectronics course. Details of the improvement are discussed in the resultssection.After the first feedback cycle, a year later, the professors met for a second round of discussionsto find further improvement techniques.

the United States. Nationwide this was accomplishedthrough the use of a method called triangulation. In this method a rather long base line ismeasured on one coast, say 25 miles, using a steel tape and taping bucks6. Using a transit toensure that the line is straight and leveling to determine the elevations of the ends of the tape, avery precise measurement is made of the base line (a very long and tedious task). See Figure-2on the left is a metric leveling rod, in the center a taping buck. The elevation of the end points ofthe tape are determined with dumpy level as shown in Figure-3.

. In order to evaluate if curriculum help develop these skills in students, anassessment instrument is needed. A wide variety of such surveys have been developed andvalidated, although generally for settings outside engineering academia. In this research, theMiville-Guzman Universality-Diversity Scale short form (MGUDS-S) was used. It is a written15 question survey with responses on a 6-point Likert scale. It evaluates universal-diverseorientation (UDO) and has been most widely used in medical school settings. The overall UDOscore is composed of three subscales: diversity of contact, relativistic appreciation, anddiscomfort with differences.

At the same time, newindustries, which required higher skill sets, began locating in the greater Portland area.These included such companies as National Semiconductor, Fairchild Semiconductor,Pratt and Whitney, Idexx Laboratories and other.

This was a result of industry feeling that engineeringgraduates were inadequately prepared for the practice of engineering. Response from thesepioneers developed what has become known as capstone courses or programs. These programsbrought open ended design problems and often industrially
