Manufacturing requires collective knowledge of material, metrology, and processes. Hands-on laboratory and lecture helps students to learn, appreciate, and be motivated for further study. Learning effectiveness in a large class, however, is reduced due to limited interaction, delaying feedback until after an exam, and tediousness of many repeating laboratory sessions. We are implementing steps to
... [Show full abstract] teach manufacturing laboratory to a large class of 250 students each semester. Complementary online instructional videos and class lectures, Clicker assessment, regular grade feedback, and cellular manufacturing laboratory exercises are utilized. Laboratory exercises are grouped into cellulars to save resources, space, and are synchronized with relevant lectures to facilitate students' understanding. For each laboratory exercise, the overall lab objectives are covered in class, but details of tooling and machine operation are shown using online professional videos so that students can view and learn at their own paces before going to their laboratory. A clicker quiz is conducted at the beginning of a lab session to gage students' understanding while encouraging them to be punctual. This online lab instruction approach allows more hands-on time for students in a lab while reducing communication gaps from lab instructors who English is not their native language. A student would have access to handouts, announcement, and cumulative grades via individual password-protected eCampus account so he/she can easily monitor the progress and know his/her ranking in class. Despite teething problems when implementing these steps, very positive student feedback, less tedious work for laboratory assistants, punctual laboratory schedule, and better exam outcomes prove the success of this approach.
