Design And Implementation Of Rtvu Teaching Assessment System Based On Struts2-Spring-JPA

It is an important way to promote the development of TV(Television) universityeducation, to strengthen the teaching quality assessment of TV university. It is an extremelyurgent task how to assess teaching quality scientifically,roundly,objectively and fairly. Atpresent, these popular similar teaching assessment systems in the field of education, neitherundertake assessment according to RTVU(Radio and TV University) teaching link such asthe curriculum, the teaching material, the chapter and the essential, also lack the function toevaluate the exam result. In the technical architecture, it is adopted ASP.Net frameworkconfined to the Windows platform, and although this part of these teaching evaluationsystems are employed JAVA technology, these architectures are JSP-Servlet-JavaBeanstructure in J2EE platform, and these architectures are short of multi-layer structure support,and development and maintenance of these systems are very complex. These unfavorablefactors affect to play the superiority of these similar teaching assessment systems itself.Therefore, it has a very strong practical significance to develop a set of practical function,advanced architecture teaching assessment system.TV teaching quality assessment methods are discussed according to TV universityeducation characteristic, and these system business cases and core processes are analyzedmaking use of UML language, and the teaching appraisal system is designed detailed basedon the framework of the Struts2-Spring-JPA in this thesis. The investigating work in thisthesis includes the following topics:1. The current teaching evaluation system and online examination system development present situation are dissected, and the teaching evaluation system demand analysis iscompleted in this thesis. Among them, for this type of teaching evaluation system analysis oflimitations, the current popular teaching appraisal system problems are expounded from twoaspects respectively of the function and technology; and it is set forth rounding four linkswhich include curriculum, teaching materials, chapters, points and so on, and the teachingprocess management is emphasized, for the relationship between formative assessment andsummative assessment; and it is described from three aspects which include an overview ofthe demand, use case analysis, and business process analysis, for TV university teachingassessment system requirement analysis.2. The overall design of the system is finished in this thesis, and system architecture isbased on Struts2-Spring-JPA integration framework, and database design is utilized astandard relational database. The system architecture design is probed from three areas whichinclude the frame choice, system layered design and program operating flow; and the TVuniversity teaching assessment system modules are divided, based on the analysis of thesystem requirements for the system module structure; and the system database design iselaborated from the teaching evaluation system database logical structure mainly.3. It is based on the object-oriented design and development, and the teaching appraisalsystem detailed design is discussed on the basis of the system demand analysis and overalldesign, and the teaching appraisal system is achieved finally, utilizing the framework of theStruts2-Spring-JPA in this thesis. This detailed design of system is probed, from the programprocessing flow, the DAO layer class diagram, business logic layer class diagram, controllayer class diagram. The TV teaching assessment system implementation is described frombuilding system development environment, realizing the system core function modules, andsystem configuration, etc. Among them, the system core function module realization processis discussed from the test question management, examination management, teaching linkmanagement, students evaluating teaching point, teachers viewing assessment results andbackground management and so on.4. In the system verification, the TV teaching assessment system is tested from thefunction, performance, availability, client compatibility, security and so on, in accordancewith three steps of the maker testing, comprehensive testing, release testing. At the same time,the TV university teaching evaluation system application is expounded, and the TV universityteaching evaluation system application effect is discussed from the perspective of the end userwhich include students, teachers, and the system administrator. Finally, the system iscompared with similar systems from the system analysis and design method, the technicalarchitecture and implementation techniques.The TV university teaching evaluation system is made use of Struts2-Spring-JPAintegrated framework, and the complex application is divided into four layers, and the systemstructure is clear, and the efficiency and maintenance of system development are improved,and the design requirements is tested through its application in the teaching effect. The system strengthens the TV university teaching management, and improves the teaching levelof TV University used by some TV university.
