Design And Implementation Of College Online Teaching Platform For Students'comprehensive Quality

In order to further promote the exploration and reform of the new mode of education,colleges and universities are trying to use colleges to further improve the comprehensive quality of students.The practice shows that the college system plays an obvious role in improving the comprehensive quality of students.Therefore,under the Internet mode,how to establish the online teaching platform of colleges and universities,so that students can efficiently complete the comprehensive quality education through mobile phones,is a very important link of educational informatization in colleges and universities at present.The goal of this thesis is to build an online teaching platform based on the new model of college system,which takes mobile phone as the carrier,and to realize the students' extracurricular activity integral.The main work of this thesis includes:1)The demand analysis and investigation of the business model of college system are carried out,and the detailed design scheme of the platform is given.The platform mainly includes two parts: the mobile phone APP,for teachers and students,the platform management for administrators.The main functions of mobile APP include activity reservation,mentor reservation,viewing activities,viewing credits,viewing credits and so on.The main functions of platform management include publishing activity information,result export,score statistics,student and teacher information maintenance and so on.This thesis designs use case diagrams for different users,such as administrators,teachers,students and so on.Then the detailed business logic is given for each functional module.Series analysis.Finally,the table structure of the database is given.2)Aiming at the cheating problem of mobile phone scan code check-in,the platform proposes to combine geographical location information to improve the accuracy of check-in.In order to improve the check-in efficiency,the system uses QR code to realize mobile phone check-in.However,this method can not confirm whether the students are on the spot.Therefore,while uploading the check-in information on the mobile phone,the system uses the geographical location information of the mobile phone to judge the area where the students are located,and improves the accuracy of the check-in.3)The thesis designs and implements the teaching platform of the college.In the development mode,the model-view-controller three-tier architecture is adopted to realize the separation of business logic,data and interface display.The system improves the efficiency of network request through Retrofit,encrypts the user information through MD5 algorithm,improves the data security,and establishes the message push mechanism by maintaining the long connection with the server through auroral push.At present,the platform has been successfully run,and stable and reliable.A large number of students took part in Zhejiang Humanities Lecture Hall,teacher and Friends Lecture Hall,Dean afternoon Tea,Secretary appointment and other activities through APP appointment,which improved the humanistic quality.And spirit.
