Brigham Young UniversityIntroductionIn this paper, we describe an innovative approach to combining research and curriculumdevelopment for the field of chemical engineering. The methodology has the potential to define anew paradigm for instruction in rapidly-evolving fields such as molecular simulation,computational chemistry, biochemical engineering, and materials science. Our immediate aimhas been to initiate a World Wide Web (WWW)-based “textbook” on molecular simulation, andto introduce it into the graduate and undergraduate chemical engineering curricula at ourrespective institutions. The textbook will have the additional role of a refereed electronic journalthat elaborates on important new developments and applications as they appear in the

opportunities to “create and do” rather than those which tell them “how thingsare done.” Courses belonging to the latter category often do not capture students’ interest. Digitalsignal processing, however, does precisely that. It can be developed within a real-life engineeringcontext with real-time applications and design projects, thus leading students to establish a directexperience with the subject rather than taking the instructor's word for it.The DSP lab at Cal Poly is developed with the above objective in mind. It supports experimentswithin the real-life context, using discrete mathematics as a tool and not the goal. It emphasizesinterfacing with the real-time world of analog signals and systems.

Just as their counterparts in industry, the faculty need to belifelong learners1. One of the best ways for a faculty member to maintain technical currency is tobecome involved in industrial projects as a consultant or in a school center that conducts appliedresearch. Besides keeping faculty members’ technical skills up-to-date, involvement in appliedresearch and consulting renders other benefits such as: (1) providing real-world case studies to beused in classrooms and laboratories, (2) strengthening relationships between the school andindustry which can boost corporate donations to the school and

There were several factors that affectedthe technology’s effectiveness in these early days, including the availability and usability ofcomputer hardware, efficiency and usefulness of the CAD programs, and the willingness ofdrafting personnel to embrace the technology, which was usually inconsistent and frustrating touse. As time progressed, improvements in the technology and its applications gradually allowedfor a grudging acceptance of CAD in the workplace, followed by general usage, and finally
