Abstract: At present, a lot of reform and practice have been carried out in the teaching of software engineering in Colleges and universities. On the basis of theoretical courses, practical courses of software engineering are added. This paper focuses on the application of the method in the requirement analysis stage in the training course of software development.The prototype method is a practical method in the requirement stage of software industry. It can quickly establish the system prototype, communicate and revise with users in time, and finally clarify the requirements, so as to improve the stability of the requirements. Based on the teaching cases of students' software development training course, this paper uses the prototype tool Axure RP to establish the prototype according to the requirement use cases, to illustrate how the prototype method is applied to the teaching practice of software requirements analysis.

Key words: Software requirement analysis, Prototype method, Teaching practice
