The operations management course is a required course in most business schools. For many students this course is extremely challenging.  It requires students to think about businesses in a holistic fashion and then apply critical thinking and mathematics to solve problems.  Typical problems involve business process modeling, process flow analysis, capacity analysis, inventory theory and tools of Six Sigma.

Studies have provided specific analysis that led to the conclusion that on-line video can improve grades and knowledge retention.  This research blends well with research from communication, psychology and cognitive science fields that discuss lectures, retention and pacing of reviews,  which indicates that not only is review of material integral to understanding, but that the timing of the review may have a direct impact on the length of retention.

This paper demonstrates how the provision of supplemental review material in the form of on-line YouTube tutorials affected students in an undergraduate operations management class.
