Curriculum Reform at Rensselaer R. T. Lahey, Jr. Dean of Engineering G. A. Gabriele Chair-Department of Engineering Science & Core Engineering Rensselaer Polytechnic Institute Troy, New York - USA INTRODUCTION Rensselaer Polytechnic Institute is currently engaged in major curriculum reform. In particular, the curricula in all the Schools at Rensselaer are being changed to a 128 credit four by four (4X4) Baccalaureate program. That is, a program of study in which students will be taking four, four credit courses per semester. The School of Engineering at Rensselaer is a leader in these activities. In addition, many of our large enrollment courses are being converted into a studio format. These "theater in the round" type courses have few lectures by professors but have intensive interaction among the students. Indeed, the students learn by doing and many of these courses involve extensive use of multimedia computer technology to aid interactive learning. Rensselaer has pioneered in the use of computers in the classroom. We currently have calculus, physics, chemistry and some of our large enrollment introductory engineering courses (eg., Laboratory Introduction to Embedded Control - LITEC) taught in this manner to all of our students. Moreover, we are in the process of converting a number of upper level engineering courses to this format (eg, Electronics & Instrumentation, The Analysis of Dynamic Systems, Health Physics, etc.). Our experience has been that a properly formulated multimedia computer-based course promotes learning in the classroom, and less contact hours are required to deliver it. Moreover, we have found that teaching is not the same thing as learning and that hypertext and computer-based visualization capabilities significantly enhance learning and customer (i.e., student) satisfaction. Thus the development of multimedia computer-based studio classes are a key feature of the curriculum reform activities atRensselaer. It should be stressed that the primary motivation for curriculum reform at Rensselaer is the desire to create an exciting new state-of-the-art engineering curriculum which not only reduces unnecessary load on both students and faculty, but can be delivered at significantly less cost (~20%). Indeed, we believe that successful technological universities of the 21st Century must do more, and do it better, with less, and curriculum reform is the key to achieving this goal. DISCUSSION Rensselaer Polytechnic Institute, which was started in 1824, has a long history of innovation in engineering education. For example, for more than 30 years a Core Engineering program has been in place. This program of study, which comprises the first two years of our Baccalaureate degree, is required of virtually all engineering students at Rensselaer. The purpose of this program is to provide our students with the foundation in technology that we feel every engineer (regardless of discipline) should have. This distinctive program will be retained in a 4X4 format, however, it is now organized around 4 major blocks of courses: (1) The Engineering Core. Courses required of all disciplines. This core includes the Mathematics and Science courses, required engineering experiences (such as design early in the curriculum), Humanities and Social Sciences, 12 credits of free electives and instruction in Engineering Leadership. (2) The Multidisciplinary Core. Four multidisciplinary core electives which each discipline will choose from a defined list of courses shared by more than one discipline. (3) The Disciplinary Core. Courses that are core to a particular curriculum. (4) Disciplinary Electives. Each discipline can outline a set of electives that students can choose from to explore a particular interest within their discipline, or acquire depth in an area in preparation for graduate study. The template for Rensselaer's new 128 credit 4X4 Baccalaureate degree program in engineering is given in Table-I. As can be seen, the students have ample opportunity to customize their plan of study and can, if they wish, obtain dual degrees in several engineering disciplines, or in engineering combined with management (e.g., entrepreneurship) or the humanities. The list of multidisciplinary courses to be shared by the curriculums is shown in Table II. Innovations There are several distinctive features of our curriculum that we have developed that will help make this curriculum innovative. These are discussed below. Engineering Leadership and Professional Development One credit modules in Leadership & Professional Development will be required in each year of the Baccalaureate degree program. In these modules the students will learn the people skills needed for successful and rewarding careers. In particular, they will learn to be effective communicators (written and oral), learn to work in multidisciplinary teams, learn the principles of leadership and interpersonal relationships and learn the value of diversity and empowerment. The first of these occurs in the freshman year, Leadership & Professional Development-I, and will introduce the students to the basics required of good teams, interpersonal skills, and leadership. The second component will be combined with the required sophomore course, Introduction to Engineering Design (IED), where students have their first extended experience in trying to work in teams in a design-buildtest experience. The third component will be provided during the junior year to introduce advanced concepts of professional development, team presentations, and leadership types. The final component will be combined with the senior capstone design courses in much the same way as the sophomore experience with the topics being focused on the transition to professional practice. Studio Courses and Multimedia Instruction Rensselaer has been leading the way in engineering education in the development and deployment of studio format courses and the use of computers in the classroom. Studio courses are designed to focus attention on student learning rather than the professor’s performance by actively engaging the students in the classroom. This is done by transforming the classroom from the one-way delivery of knowledge, i.e. the 50 min lecture, to interactive sessions made up of mini-lectures and team oriented exercises in the classroom that encourage the students to discover the knowledge through their own activities. A typical course consisting of 3 hours of lecture and a 1 hour problem session will be reorganized into two 2 hour studio sessions with each session providing the mini-lecture/exercise session format. The studio format has already been implemented in our Physics I & II courses and our Math I & II courses. We have also begun implementing this format in the courses Introduction to Engineering Analysis, Chemistry of Materials I&II, and Strength of Materials. Experience with the studio courses has shown that student activity in the classroom is much higher than the typical lecture. Attendance is up, and tests of retention show that students are understanding the material better than in the past. In addition to the implementation of the studio courses, we have begun wide spread use of the computers instruction in the classroom including the use of multimedia instruction. As stated in the introduction, we currently have several of our large enrollment courses making active use of computers in the classroom, such as the use of Maple in the mathematics courses and freshman engineering course, Introduction to Engineering Analysis. The physics courses and the multidisciplinary course, Laboratory Introduction to Embedded Control, make extensive use of multimedia instruction in the classroom. These courses have typical semester enrollments of 250-350 students. We have found significant advantages to using multimedia instructional modules in the classroom in assisting student learning and reducing the required teaching resources. Our future plans call for us to continue development of multimedia instruction in our upper level courses. In particular, those courses with high enrollments can employ multimedia to help make efficient use of teaching resources, to increase student understanding through improved visualization, or to allow for easy customization of multidisciplinary course material to incorporate discipline specific examples. Multidisciplinary Design Laboratory The Multidisciplinary Design Laboratory (MDL), which is currently in the development stages, will be used to emphasize the multidisciplinary nature of engineering, and help to train our students to be effective members and leaders of multidisciplinary engineering teams. The MDL consists of two major elements, a design curriculum centered on providing a multidisciplinary design experience at the senior level, and a facility that supports design courses and multidisciplinary hand’s on activities. The curriculum portion of the MDL combines the senior level capstone design courses that currently exist in every department into a common, multidisciplinary capstone experience. This will bring together students from different disciplines into design team settings that provide experiences more closely attuned to the real world of engineering. Design problems are inherently multidisciplinary. By bringing groups of students from different disciplines together at the senior level, students have the opportunity to better understand what other disciplines contribute to a design activity, as well as gaining a better appreciation for their own discipline and skills. This curriculum development has been underway since the 1995 fall semester and should reach full implementation within the next two years. The MDL facility provides two different areas, a design teaching area, and a multidisciplinary experimental laboratory. The design teaching area is being developed to support the team oriented work that goes on in the sophomore design course (IED), and the multidisciplinary senior capstone course described above. This will be a large room configured to support both lecture activity and design team meetings. Support for advanced engineering workstations, white board technology, and video conferencing are also planned. The multidisciplinary experimental area will provide a space to focus many of the dispersed activities in our instructional labs that are common to many curricula, as well as provide space for those activities that are inherently multidisciplinary. An example of the first type of space would be the need for materials testing. Several curricula (mechanical engineering, civil engineering, and materials science) employ some type of materials testing as part of their undergraduate labs. These labs would be consolidated into a common area of the MDL. Multimedia instructional modules would be incorporated as part of the lab to assist students in understanding the equipment, experimental setup and data collection methods. An example of the second type of space, inherently multidisciplinary activities, would be large design projects, like the RPI composite sailplane project, the mini baja or the Formula SAE projects, the teaching factory, and the Advanced Manufacturing Lab. CLOSURE These are challenging and exciting times for engineering education. Currently there is over capacity in the country for the delivery of engineering education, and there are unrelenting pressures on all of us to reduce costs and to improve our educational programs. The schools that will emerge strong in the 21st century are the ones that successfully respond to the needs and pressures of the market place, and the ones that offer a distinctive and valuable educational experience for their students. It is felt that curriculum reform is the necessary but not sufficient condition for future success and Rensselaer is pleased to be in the forefront of these important activities.
