new multi-disciplinary course in Product Dissection has been developed, distributed electronically, and implemented at Penn State, the University of Washington and the University of Puerto RicoMayaguez. The course examines the way in which products and machines work: their physical operation, the manner in which they are constructed, and the design and societal considerations that determine the difference between success and failure in the marketplace. The primary objectives of this course are to develop a basic aptitude for engineering and engineering design, and to develop mental visualization skills; by examination of the design and manufacture of consumer and industrial products. This course is intended to complement engineering science and mathematics courses and to show freshman or sophomore level students how these fundamentals relate to engineering practice. The course is modular and consists of self-standing dissection modules on: bicycle, electric drill, four stroke engine, Funsaver disposable camera, and telephone. This paper describes the philosophy and content of this course and presents results from two years of development and deployment.
