This is a use case diagram showing the interaction between professors and students. In the flowchart, the professor and the student act as two nodes each, and the eight activity arrows between them represent the interactions between them. Through this flowchart format, the interactive relationship and process between professors and students can be clearly seen, so that the importance of this interactive relationship for the improvement of teaching quality and learning outcomes can be better understood and assessed.
