Implementation of a Novel Second-year Mechanical Engineering Course to the Curriculum

Abstract

In 2012, the University System of Ohio member universities, which are overseen by the Ohio Board of Regents, moved from operating on a quarter-based calendar to a semester-based calendar. In conjunction with this change, the Mechanical Engineering curriculum at The Ohio State University was revised, and a new and unique course was added to the required curriculum for students in the major. The course, titled "Introduction to Mechanical Engineering", encompasses elements of both the spiral curriculum and experiential learning strategies 19,20 . A prior ASEE paper 1 outlined the structure of the course at the time of pilot development, and the student feedback provided by the pilot program participants. Now in its third year of full-scale implementation, the course has undergone some modification from its original design. Additionally, exploration has begun within the department in order to incorporate additional elements of the mechanical engineering curriculum into the course in a more comprehensive spiral approach.The key challenges for this course are that it is a required course for all students in the major in a very large department, and that it is a hands-on course in which all students are required to complete every aspect of the machining, assembly, and programming of a compressed air motor individually. The course was designed specifically with this requirement to ensure that every student interact directly with every aspect of the process, in order to prevent the specialization, uneven participation and resulting uneven skill and knowledge gains that can occur in group project settings. One interesting outcome of the course has been the relatively large number of female students who completed the course and then applied and were selected as undergraduate teaching assistants for the course. In a department and discipline where female students remain under-represented overall, they have been participating at high levels in this role. We report here on the evolution of the course from its original pilot program through the first four semesters of full-scale implementation, as well as future plans for the course. Our assessment includes detailed feedback from students and teaching assistants who completed the course in the initial two years.

Design Course in a Mechanical Engineering Curriculum

“…Using undergraduate teaching assistants to help manage the class is not new [18]. We value the peer learning cycle and students benefit from working in teams and with former students.…”

“…Using Arduino in an undergraduate mechanical engineering design course is not new [2][3][4][5][6][7][8][9]. Many higher institutions have chosen to incorporate it into a sophomore-level design classes where most students have already gained design, CAD, or coding skills prior to registration.…”
