Hands‐On Experiences: An Integral Part of Engineering Curriculum Reform

Abstract

AbstractThe concept of “hands‐on” experiences, through Mechanical Dissection classes, as a part of engineering curriculum reform is presented. Mechanical Dissection in this context refers to a process of studying the function of a mechanical system and dismantling it in order to see how its specific function is realized. The functions of various components within the artifact and interaction between the components are also studied. Awareness of the design process, multiple solutions to a design problem, and the evolution of the technology of various artifacts and their components are focused upon. This is followed by systematic re‐assembly of the artifact. The courseware and supporting laboratory modules were developed to address specific objectives. They provide the foundation for better understanding of sophomore, junior and senior courses, particularly the design oriented ones. Seven in‐depth dissection modules form the basis of this course. These are a weighing scale, a money sorting machine, an electric lawn mower, an electric hand drill, a gasoline engine, a centrifugal pump and an eighteen speed bike. This course is targeted at freshman or sophomore level engineering students. Some of these modules can be simplified and transported to K‐14 students. Assessment of this course has shown an overwhelming positive response from students in all aspects. This makes the course an integral part of engineering curriculum reform.
