Design And Implementation Of Virtual Simulation Experiment Teaching Resource Management System Based On Android

With the promotion of informatized experimental teaching in colleges and universities,the online virtual simulation experiment is becoming imperative.Compared with traditional experiment,the online virtual simulation experiment can provide an unrestricted experimental environment for teachers and students,and solve the problems faced by experimental teaching in colleges and universities,such as the shortage of venues,teachers and equipment.Based on the requirements of the virtual simulation experiment center,a virtual simulation experiment teaching resource management system based on Android is designed and implemented in this paper.The system meets the mobile-access needs of the teachers and students to mobile-access the virtual simulation experiment management platform,and meets the needs of teachers for mobile office.As a part of the virtual simulation experiment center,this system relies on the virtual simulation experiment management platform and works as a Android APP.Teachers,students,and administrators can use this APP to access and manage the teaching resources and realize real-time interactive by Q&A function module.Android Studio main development platform in implementing this system,adopting the idea of layered design.The system consists of five functional modules,including message push module,experiment management module,homework management module,interactive Q&A module,user management module,and setting module.The term frequency position weighted search sorting algorithm is adopted in Q&A module to realize the retrieval of historical information by keywords and display the search results according to the relevance of content and keywords.The purpose of the search function is to reduce repeated questions and repeated responses of teachers.After testing,the virtual simulation experiment teaching resource management system based on Android can meet the user's functional requirements,and the Recall rate and accuracy of the sorting algorithm meet the demand,which achieves the expected development purpose.
