Thus most of our masters degree programs are approximately 72 quarter hours long of which 12 hours are devoted solely to thesis research. This gives our students much more breadth and depth than is normally expected for a masters degree. This will become apparent in section III where we discuss curriculum details. The instructional system development (ISD) model shown in figure 1 is the basis for ensuring our curricula is responsive to the needs of the Air Force and other employers of our graduates.

Both World War II and Sputnik served as wake-up-calls to the universities to do something aboutengineering education, that is, a shift in the education of the engineering student to emphasize the scienceunderlying engineering. Not only courses, but research as well, reflected this change.

They are required toconsider that broader view when choosing the kind of project and specific topic on which they will focus theirwork. They learn to be more reflective about their chosen profession and senior project by asking questions abouttheunderlying assumption in our culture that all science and technology is progress in and of itself. The courseencourages the students to view engineering from different perspectives, for example, from history, sociology,anthropology, psychology, comparative literature and philosophy.

He also changed the character of the design projects, making them more open-ended and more conceptually challenging. The impact of this change is reflected in the abrupt upward shift of the curve for Term 96-1. Though this result is preliminary (the term is in still progress, as of this writing), it clearly suggests that the course director’s changes have had the desired effect. Student preparation for class is once again at an appropriate level. The interim time survey graph for Term 96-1 is shown in Figure 5.

Students develop an appreciation for the manycomponents necessary for a closed-loop control; they also recognize that closing a loop is not aseasy as they may have thought. Often students need to recognize that they do not know all of thefactors that affect the current problem. Many questions are open-ended.
