In the teaching process of the course of operating systems, process synchronization is both a key and the biggest difficulty.This paper, through transforming the definition of E-R diagram in database, proposes process synchronization teaching method for computer operating systems based on modified E-R diagram.The method formulates process entities in rectangles, among which a diamond indicates links between entities and an oval represents the semaphore that generates association; thus able to clear reveal the connection between process entities as well as that within the entity.Teaching practice shows that this method is not only advantageous to the description and analysis of the process synchronization problem, but also helpful for students to master the ideas of process synchronization design.In addition, it can improve their ability to solve the problems related to process synchronization.
