Design And Implementation Of A MVC Based Remote Teaching Aided System

With the rapid development of computer technology and Internet technology,entering the 21st century,people can acquire a large number of teaching resources from the Internet,in which "long-distance education teaching assistant system" is the important technology tool and basic information system.This paper analyzes background and significance of long-distance education,proposed design scheme of "long-distance education teaching assistant system",using the MVC design concept,using Hibernate,Spring and Struts framework and relevant database technology,a model based on MVC,and realize the key technology of this system,and verify the effectiveness of the scheme.Main work is as follows:(a)About the question of mass user permission management and inefficient multivariate data operation,this paper proposed a design scheme of "long-distance education teaching assistant system" which is based on MVC.It mainly uses the technology of WEB,B/S and MVC,designing by the method of role-based access control(RBAC),effectively realize the multi-user access control,and design the JPA interface(javax.persistence and javax.persistence.spi)and Hibernate framework to complete mapping from relational data tables to POJO object and operation management.(b)This system achieves the key module "long-distance education teaching assistant system" by JSP and Spring,Struts,Hibernate framework in combination.Through designing system management module to configure user data,system settings and security policy,and effect teachers and student information management and certification.The online examination module of questions primarily through resource input,modify,and delete,examination room set up,test difficulty degree set,the greatest degree of simulation of the real exam features traditional classroomto improve the effectiveness of the exam tests.The curriculum resource management module,mainly through the Internet search-related teaching resources sufficient to form a system of their own advantage Knowledge of teaching resources,and students can obtain real-time online classroom teaching broadcast live,at the same time,to improve the quality of learning,they can learn and review by downloading the excellent instructional video,etc..The application of the above solutions and technologies to achieve a practical distance learning support system,achieve a clear structure,functions,system testing indicates that the remote system is a good teaching aids,efficient and stable operation.(c)Implementing "long-distance education teaching assistant system" by the above solutions and technologies,achieve a clear structure,functions,system testing indicates that the remote system is a good teaching aids,efficient and stable operation.In summary,the MVC model and the technology are the main theories and methods of network teaching system in this paper,and based on this solution,implementing the key technology.It has reference significance for the development of similar systems.
