Session 12b5 ECE 21: A New Curriculum in Electrical and Computer Engineering Kevin Scoles Nihat Bilgutay Electrical and Computer Engineering Drexel University Philadelphia, PA 19104 Abstract – The Electrical and Computer Engineering Department at Drexel University has revised and completely restructured the 5-year coop degree in Electrical Engineering. The new curriculum, called ECE 21, provides depth and breadth in subject area, with significant flexibility in course choices and concentrations. Concentrations, or tracks, have been defined in the subject areas of Computers, Controls and Robotics, Electric Power and Energy, Electronics, and Telecommunications. Our curriculum delivers design and laboratory experiences throughout the five years and enhances teamwork and communications skills. Assessment instruments are in place to insure that the ECE 21 curriculum will improve on a continuous basis. Nomenclature Core Elective: A pre-junior or junior course from outside the student’s track E4: Enhanced Educational Experience for Engineers Pre-junior: The third year of the five-year Drexel program with coop Term: Drexel has 10-week quarters and one week for final exams tDEC: The Drexel Engineering Curriculum, the current title of the first and second year curriculum in engineering Motivations for Change Drexel University’s College of Engineering began to make fundamental changes to its curriculum with the Enhanced Educational Experience for Engineers, or E4, program in 1989 [1 - 3]. What began as an experimental program in redesigning the first two years of engineering was in 1994 institutionalized for all entering students as “The Drexel Engineering Curriculum,” or tDEC. In 1989, 100 students were accepted into the E4 program. Over 700 students participated in this program in the fall of 1998. While some of the details of the E4 program have evolved in the intervening years, the philosophy remains essentially the same. The first years of the curriculum should deliver “engineering up front,” integrate the basic sciences and engineering, provide hands-on engineering design and laboratory experience, and enhance communications and teamwork skills. Comparisons of the first two years of the traditional and new curricula are shown in Tables 1 and 2. Descriptions of the tDEC courses can be found at http://wwwtdec.coe.drexel.edu/. The success of the new tDEC curriculum [4] stimulated all departments, through the College Curriculum Committee, to examine their upper level curricula, and a common framework for curriculum change was developed. An example of the template is shown in Table 3. Each of the departments in the College was free to design their new programs within the framework. Within the Electrical and Computer Engineering (ECE) Department, we considered several motivations for curriculum change. Among these were: • Students coming to the upper level curriculum had different experience and expertise. We thought that we should adapt to make use and enhance these skills. • A review of the curriculum had not been done for many (~15) years. Table 1.

This had been picked up through the advising system and through exit interviews with seniors. • New teaching tools and new technologies had developed courses. • We would consider not trying to teach everything to everyone. Ours is not the only ECE department considering or implementing this idea [5]. • We would provide a system that lets students make more choices Development There was considerable debate in committee and among the faculty when we began this revision project. Some of these questions were: Within our departmental curriculum committee, we considered several major conceptual changes: • We wanted to bring ideas of hands-on or experiential learning, integration of computer tools, teamwork, etc. to the upper level curriculum. This would address the new capabilities of the students entering the upper level • What topics or courses make up the “core” of a discipline? • How could you graduate someone with an EE degree without EM fields, machines, devices, or other traditional topic?

Results The result of our faculty deliberations is a new curriculum that we call “ECE 21.” ECE 21 has been phased-in over a three-year period, and now with this year’s senior courses, is completely in place. Many new courses have been developed, such as Introduction to Digital Signal Processing, Energy Management Systems, and Computer Control that were not available in the traditional curriculum. Other courses have been revised to include new computer tools or laboratories. Tracks The new curriculum has a set of paths, or “tracks,” which follow the educational interests and research expertise of our faculty. The tracks are Computers, Controls/Robotics, Electric Power and Energy, Electronics, and Telecommunications. The tracks begin in the third (prejunior) year and run through the senior year. Each student must complete one track. With their technical and free elective choices, students can complete a second track, or choose courses from several tracks to suit their particular goals. Thus we can provide depth in a particular area, as well as breadth across many topical areas. An example study plan for the Electronics Track is shown in Table 4. The courses in circuits, transforms, devices, circuits, and fields in terms 6 through 9 are descended from those in the traditional curriculum. However, courses in communications, controls, and 0-7803-5643-8/99/$10.00 © 1999 IEEE November 10 - 13, 1999 San Juan, Puerto Rico 29th ASEE/IEEE Frontiers in Education Conference 12b5-12 Session 12b5 machines, which were mandatory in the traditional curriculum, are now optional. The plans of study for the other four ECE 21 tracks, as well as the course descriptions, can be seen on the ECE web site, http://www.ece.drexel.edu/ECE/ece_curricula.html. The junior year (terms 8 and 9) workload has been reduced from the four ECE courses in the traditional curriculum to two ECE courses, an ID course, and a 2-credit lab. Laboratories The ECE Laboratory sequence is a new feature of the ECE 21 Curriculum. The laboratories in the third and fourth years deliver hands-on experience in each of the track areas. They are important in developing the breadth of each student’s knowledge, since they will have lectures and experiments from outside their track each term. Each course has one hour of lecture and two hours in a computer lab or experimental lab per week. This approach provides laboratory and/or design project experience to our students throughout the curriculum (i.e. every term). Interdisciplinary Courses The purpose of the interdisciplinary (ID) courses is to return some of the basic science and mathematics that had been removed from the 1st and 2nd years of the traditional curriculum (i.e. “inverted curriculum”). Examples of ID courses are: • Mathematical Modeling for Engineers, which has as its primary content Linear Algebra with engineering applications, and is taught by the Mathematics and Computer Science (MCS) Department. • Errors, Uncertainty, and Reliability covers topics in probability, and is taught by the Electrical and Computer Engineering Department. • Vectors and Complex Analysis, taught by the MCS Department. • Programming for Engineering and Science (C language), taught by the MCS Department. The first three of these course are used to meet the ABET Program Criteria requirements for Electrical Engineering degrees. Other courses that have been developed by the Gateway Engineering Foundation Coalition schools are also being considered for adoption as ID courses (Manufacturing, Environmental Engineering, Bioengineering). Discussion In ECE 21, students can freely choose their track. Currently, the Computer and Telecommunications tracks are the most popular, followed by Electronics, Controls/Robotics and Electric Power, in that order. The flexibility tends to make class size and teaching load predictions more uncertain than in the traditional curriculum where you knew, for example, that every junior on campus would be taking Communications Theory in the term it was taught. Some of our students have spoken of feeling like guinea pigs, and in a sense they are, especially our seniors, who have been the first to go through the new curriculum. However, some of the seniors who graduated last June expressed regret that they did not have access to the choices and new courses available to the classes behind them. Curriculum assessment will have a major role in improving the new curriculum. A new course evaluation process is in place (to be presented at FIE ‘99) to assess student attitudes of their competency in core technical areas, as well as course structure and faculty performance. Our practice of doing senior exit interviews will continue. Results of student evaluations by co-op employers are being collected, and alumni follow-up is planned. ECE 21 has been presented to the ECE Visiting Committee with favorable responses. Conclusions We have revised and completely restructured the 5-year coop degree in Electrical Engineering. This is perhaps the first EE degree program with this structure. The ECE 21 Curriculum provides depth and breadth in subject area, with significant flexibility in course choices and concentrations. Our curriculum delivers design and laboratory experiences throughout the five years and enhances teamwork and communications skills. Students can do minors, dual majors, or pre-professional preparation with the flexibility attained. Following our assessment efforts we will report on the outcomes of the new curriculum.
