The mechanical engineering curriculum prepares students for employment in a broad range of industries [1]. In the Midwest, many graduating mechanical engineering students will find employment in manufacturing-related fields. This is especially true in Ohio, where 17.8% of the total gross state product is accounted for by over 12,000 manufacturing firms [2]. For this reason, manufacturing courses play an important role in preparing mechanical engineering students to succeed in these industries.While most engineering courses are calculation-or design-intensive, manufacturing courses tend to be primarily information-driven. Covering this content through traditional lecturing often fails to fully engage student interest, motivation and learning potential. Research on student engagement in higher education indicates that improvements to course design and content delivery can improve student engagement [3][4][5][6][7]. Recommendations to instructors include developing interactive course activities [4], incorporating online multimedia resources [5][6][7], and integrating practical experiences into the delivery of the course content [7].The purpose of this paper is to describe and evaluate the changes made to a traditional manufacturing lecture course that sought to improve student engagement and learning. The new course structure consisted of four components: 1) self-learning outside the classroom, 2) handson manufacturing experiences, 3) a lecture incorporating active-learning exercises, and 4) a TED Talk-style final presentation.
Student and Course Background:The University of Mount Union is a private, liberal arts institution located in Alliance, OH. The Engineering Department offers ABET-accredited undergraduate degree programs in mechanical and civil engineering. Of the nearly 2200 students enrolled at Mount Union, approximately 130 are majoring in one of the engineering disciplines.A manufacturing science course is required for mechanical engineering students during the spring semester of their final year. The course is comprised of a 2-credit-hour course lecture and a 1-credit laboratory. Before spring semester of 2017, the course followed a more traditional structure. Readings were assigned out of a manufacturing textbook, the manufacturing processes were described during traditional academic lectures, and tests were proctored to assess student learning. The 1-credit-hour lab was used to tour five local manufacturing facilities throughout the semester. A comparison between the 2016 and 2017 course structure is shown in Figure 1.
