The Design And Realization Of The Micro-video Teaching System

With the continuous development and advancement of educational concepts,the role of online course teaching platforms in modern education reform is becoming more and more important.The online course teaching platform has the following advantages:the traditional teaching method has great limitations in teaching time and space,and the online course teaching platform can make the teaching process out of the time and space constraints,so that students can learn flexibly according to their actual situation.It is a good example of the teaching philosophy of teacher-led and student-centered in modern education reform.Based on the software engineering idea,this paper designs the physical micro-video teaching system of higher vocational school,and uses UML technology and.NET technology to realize the development process of the teaching system.Through the field investigation of the teaching of higher vocational schools,the three functional modules of the micro video network platform are designed:video management,user learning and system management,and UML technology is used to analyze the three use cases.Firstly,the teaching platform allows the teacher to upload the teaching-related micro video through the micro video management module;and the micro video learning function module is the main body of the teaching platform,and the student user in the platform can perform the micro video learning through the function module.And the platform system management module is mainly prepared for the system administrator to facilitate each user in the management platform,and allows the system administrator to approve and recommend the micro video uploaded by the teacher.The micro-video network teaching platform adopts B/S three-layer structure design,in which the interface layer is the interface for the micro-video network teaching platform to interact with the platform users;the data persistence layer saves user information and micro-video course description information through the SQL Server2012 relational database.And micro-video course evaluation and other information;the business logic layer can respond to requests submitted by each user in the platform,and return the processing results to the interface layer.The micro-video teaching platform is implemented by.NET technology.At the end of the paper,the functional test and stress test of each module of the micro-video teaching platform are also carried out,and good test results are obtained,which effectively illustrates the micro-video teaching of this design.The platform can meet the needs of users.
