Design And Realization Of Mobile Education System Based On Andrews' Vocational Colleges

At present,the mobile Internet is booming,and the Android system has become the smartphone operating system with the highest market share.However,most vocational colleges send academic information to PC-based education systems,which arenot conducive to the faculty and students' convenient and timely access to relevant information.At the same time,the current educational system also lacks the specific needs of vocational schools in teaching management.The system needs to be upgraded and the functions expanded and extended in order to provide education services for teachers and students.In view of the above problems,this thesis is guided by the thought of software engineering,based on the digital platform of the school,combined with the characteristics of the full-time colleges and the current needs,to understand the content and requirements of the school administration,Sexual and non-functional requirements of the basic needs of the design and implementation of Android-based mobile education system.Front-end application of the system,back-end management and database design and development.In functionally,it realizes the transplanting of "mobile platform" to the modules such as "education system" and "library management system" in campus,and has built a "notification circle" in the application modules of teachers and students to realize receiving push information and notification,Students through the creation of learning circles and the release of information to achieve the class and learning circle interoperability of information and teacher-student interaction and a series of operations.In the teacher application module to increase the "classroom management" to achieve timely feedback on classroom information;teacher users can use the phone to attend the classroom attendance,evaluation class,homework assignments,teaching records and other classroom records.In order to solve the problems of education news recommendation,book recommendation and circle recommendation,especially the collaborative filtering recommendation algorithm is introduced.Through the design and implementation of the algorithm,the system performance is improved and the user stickiness is enhanced.Based on the Android system and the idea of MVC architecture,this dissertation adopts object-oriented design method and follows the latest Android Design standard to UI design of the system,and combines Navigation Drawer and Fragment components.In the process of using Roboguice annotation framework to improve testability;AsyncHttp Client to asynchronous network requests;Use Gson open source library to achieve Java objects and Json direct serialization.With the Android mobile education system in the campus of the promotion and the formal use of the majority of teachers and students can use the Android mobile terminal for daily affairs management,after-school use of mobile phones to learn to communicate class teacher feedback on classroom situations through the mobile terminal platform to Realization,the system brings great convenience to the work and study of teachers and students.Compared with the traditional way,improve work efficiency,realize paperless office.
