Abstract
This project intends to innovate teaching methods and materials for the course "Operations Research II" using the "flip classroom" mode. In particular, the content of the course will be restructured and renovated based on concepts and the difficult concept will be divided into small segments for students to learn more efficiently. Before each class, all students will be required to watch videos and then work on the exercises together with their group members. Students therefore have more opportunities to interact with the instructor and their peer classmates. Also, there will be more time for students to ask questions if any. The experiences gained from this class can be shared for other classes' reference.
