complete system. This objective is approached by starting with the simplestpossible system model: a DC gain; and the simplest possible controllers: open-loop (offset andproportional terms) and P-type closed-loop control, designed to meet a loop-gain specification.Nonetheless, the exercise involves identifying the DC gain, designing control, and measuring,comparing and contrasting controller performance. To prepare the student, the prelab mustintroduce several topics: Topics of Prelab 1: a. Introduction to the servo hardware and software. b. Determining DC gain and designing open-loop control. c. Designing P-type closed-loop control. d. Designing P-type closed-loop control with feed forward

participants in lectures.In recent years, PBL has been gaining popularity because of itseffectiveness and flexibility. It can be implemented in many waysin accordance to the course requirement and instructor's choice. There are two common concerns with regards to implementingPBL method [2]. The first is that with the method instructors maynot be able to cover the same breadth of content as the subject-based approach. The second is that the method requires smallstudent-to-instructor ratios, a condition difficult to fulfillbecause of financial constraints. Our experience showed thatthese concerns can be dealt with by (a) careful selection ofprojects and instructional formats; and (b) effective use ofdiscussion sessions. Instead of working on one

These pilotcourses have been so successful that further courses are being developed and active recruitmentis planned for the Fall 97 semester. Method of Delivery At present five courses have been developed that are suitable for study at home orindustry. The following methods of delivery have been implemented.1. Course Packs.

the reasons for fewer jobs in power engineering,the most important ones are:(a) Electric utilities are in general not hiring engineers since they are busy re-structuring (down-sizing) in order to be competitive when the deregulation of the utility industry takes place in the near future.(b) Other “power” industries (e.g., motor-drive manufacturers) are also down-sizing and tend to hire experienced engineers or recent graduates having a broad-based background in power engineering (e.g., power, power electronics, microprocessors, etc.). This broad- based power background can be only obtained at a few tier-1 universities. On the other hand, companies with close ties to the University are

Theobservations of the instructor were corroborated by the students through the use of a confidentialself and peer review form which each student was required to fill out for themselves and for eachof the other team members. The instructor also used the form for each of the team members.Results of the review of the instructor and students were remarkably similar including even thewritten comments. A copy of the form is given in Appendix B.

Results: The plotting of data points is not a difficulty but the choice of scales for the axes takes some time to learn.CONCLUSIONS:No scientific study has been made of the effectiveness of this teaching procedure on the studentsskills. However some data on grades during the evolution of the course for the past 12 years isinteresting. Prior to 1989 the course was taught as lecture only. There were no labs, no reports,some library assignments. For the five years, 1983 through 1987 the final grade distribution was(141 students) A 23%, B 41%, C 29%, D 5%.For the years 1991 through 1995 the distribution (104 students) was: A 22

Although some textbooks have been adding "design" problems recently, anoverwhelming majority of engineering problems in textbooks are still one of the format "GivenA, B, C, and D, find E and F," as illustrated in Example 1.

The act of design can be seen as transforming afunctional representation, F, to a design description or physical representation, D, through thebehavior, B, and structure, S. Thus, designers develop a functional requirement for a design, F;determine behaviors, B, that will result in fulfillment of those functions, and select structures, S,to cause those behaviors. The expected behaviors, Be, may not match the behavior of thestructure, Bs, and so an evaluation stage may be required. Also, we have added to this process P,the representation of the problem, that must be transformed into a functional
