Abstract - The hallmark of the newly configured Rowan College of Engineering undergraduate program is the interdisciplinary, project oriented clinic sequence that spans 8 semesters. This sequence is taken by all engineering students. In this paper, we specifically describe the innovative efforts in the second semester of Freshman Clinic that is devoted to competitive assessment through reverse engineering. Specifically, experiments on a low cost consumer appliance (electric toothbrush) are described. This will enable the freshman students to determine how scientific principles, material properties, manufacturing techniques, cost, safety requirements, environmental considerations and intellectual property rights impact the design of a product. Also, the students perform experiments illustrating the engineering principles of the electric toothbrush.

Introduction The College of Engineering at Rowan University is composed of four departments, namely, Chemical, Civil, Electrical and Mechanical Engineering. In each year, there are between 25 to 30 students in each department. This results in 100 to 120 students in the entire college. The size of the college has been chosen to provide specialization in small departments and permit the creation of a multidisciplinary curriculum in which laboratory/design courses are offered to all engineering students. The hallmark of the Rowan program is the interdisciplinary, project oriented clinic sequence. This 8 semester long sequence is taken by all engineering students.

The Engineering clinic is based on the medical school model and involves side by side interaction among students and faculty for performing laboratory experiments, design projects and research. Multidisciplinary design projects and laboratory experiments at the freshman and
