Design And Implementation Of Online Marking System Of Arbitration Subsystem

Computer advances in the development of society has played a pivotal role,and now,network,multimedia and other technology speed up the pace even more.The examination system of China's extensive make use of computers and various technologies,such as online registration,online examinations,online newspaper voluntary,online marking,etc.The introduction of these new models in order to achieve the ultimate test of the principle of fair and just marking the ultimate aim for.It combines the traditional manual scoring with modern high-tech,using the separation of examination papers and answer approach,the objective title automatically by a computer sub-contractors,subjective scoring title by different teachers in the computer through the network of the electronic images of candidates,respectively,of respondents to score,the final automatically by a computer system for the nuclear sub and check results."Fair,just and open" examination system has been the principle of carrying out, in the past,marking the existence of more defects,such as marking,such as it is difficult to guarantee quality,on-line scoring system has changed the appearance of this state,so that marking an increase of quality can be controllability and increase the efficiency and reduce errors.This paper describes the online marking system as the online marking system of arbitration information management system,and its main feature is marking the second assessment,and three teachers in the post-assessment test score.Through this platform, students can answer the ultimate judge.The role of arbitration subsystem of the whole process of online marking the supervision of teachers in the marking of examination papers for marking the process of marking,the arbitrator through the arbitration of the indicator curve subsystem master marking the quality of the teacher's comment,and controversial papers and the final evaluation score.The paper introduces characteristics of the project,the use of browser-based B / S model of network development.In this paper,a combination of WEB applications,SSL technology and multi-tier architecture using J2EE.In the front-end,integrated html, javascript,jsp technologies such as the composition of user interaction layer - that layer; all the business logic layer in the middle,and JSP provides data acquisition services. Intermediate application layer,the use of similar products in the dominant BEA's middleware server for the application to provide a reliable operating environment.In this level,the use of MVC pattern,the business logic and data separation,both for a reasonable division of labor,speed up the development speed,but also enhance the performance of the system。Monitoring the completion of the arbitration system has been mainly the quality of marking examination papers.Marking the quality of the teacher's comment was a negative error value if allowed to fall within the scope of assessment and marking sections marking the progress of teachers.Ultimately the construction of software services in management,and to promote and enhance the management,further promote the standardization of online marking system.Arbitration subsystem online marking system has the following characteristics:Subsystem design is completed after the arbitration,and the arbitrator may be marking the existing mandate for the different ways in accordance with the adjustment, the purpose of reaching a balanced comment.Marking the completion of the Review staff performance statistics,Statistics Review Group of Members of each marking average and the average scoring rate,and comment aggregation group.Marking can easily grasp the person in charge of real-time marking the progress of the marking system to provide real-time progress of the inquiry.Not only subjects of each marking the progress of each test can be master of marking progress.Review quality control include:Review paper checks,Review staff score curve,quality feedback information management,dealing with the same volume,abnormal papers deal with the difference curve of complex assessment,team monitoring,marking member score error,score distribution curve,the mean score curve,curve of the daily average score,score standard deviation curve,the daily standard deviation score curve,the efficient score statistics.
