Mechanical Engineering Design (i.e., Machine Design) is a pivotal course in any Mechanical Engineering or Mechatronic Engineering curriculum. This course marks the transition from learning fundamental mathematics and science to applying them for design of engineering solutions. Combined with its rigorous and varied content, the manufacture and build of said design solutions presents a definitive experience for undergraduate engineering students. At California State University Chico, Machine Design is a four unit class consisting of three weekly one hour lectures and a two-hour activity. The purpose of this paper is to consider the effectiveness of a hands-on semester design project facilitated through the weekly two-hour activity to improve the student learning experience. In other words, does requiring students to design, build, and test a machine help them to better understand the course material of Machine Design? The semester project in this study involved designing and building an electric ceiling hoist but with a novel twist. A point scheme incentivized teams to develop a higher lifting capacity, but stress, deflection, and lifting time were competing forces. Two surveys were administered to help quantify any said benefits towards an improved learning experience. The first one was given early in the semester to assess student background while the second was given upon project completion. A careful evaluation of student feedback and measured performances is presented herein.
