Design And Implementation Of Competition Management System Based On Online Testing And Evaluation

The college competitions play an important role on activating the campus cultural atmosphere, improving students’ s pratical ability, activating students’ innovation consciousness, and thus improving the quality of practical professional students. With the rapid development of networking techniques and the prevalence of network applications, more and more universities have adopted information management platform to organize competition. However, some limitations of the existing competition system are listed as follows. Small group of experts but most common tutors of competition take part in the review process in the competition. Students should pay very high cost in participating the competition. Easy operations under the table in the process of contest and review corrupt the reputations of competition. Thus, to take advantage of Internet and cyberize the competition management in the whole process is an important way to enlarge the scope of students or colleges participating the competition, reduce the competition cost and improve the competition’s credibility. Recognizing those limitations, we design and develop a competition management system based on Internet testing and evaluation, where the requirements in both mobile commerce knowledge competition and mobile phone application programming competiton of Jiangxi provincial competition of mobile application design competition in colleges. This dissertation elaborates its design and implementation. The main works in this dissertation are given out in the following.(1)Firstly, the overall survey on the competition mode at home and abroad is given. Then, the dissertation summarizes the characters of social network, describes and compares the traditional review mode and online review mode, and presents the existing problems to elicit the research content of the dissertation.(2)Three networking competition management models are proposed. The networking competition questions management model transfer the traditional question-set way to networking and public. By the new way, users can set competition questions online after they are audited on the background. The questions will be merged in the questions databases after being audited. This model convenience the work of competition question database management. The networking competition testing management model transfer the traditional invigilation way to networking one. By the new way, remote participants’ online testing process should be picture-recorded, uploaded to public video website, checked by Internet users and competition reviewer. This model assures the realness and legality of competition. The networking competition answers reviewing management model allows the tutors and other roles of competition to become review experts after an interaction process background and foreground. The system will assign the review tasks to each expert. The experts can download online new evaluation tasks, review it and give out a score for that answer or works. There are some processses to deal with drawback of review tasks and the abnormal of review results. The system will produce the final results of competition according to the ratio among different roles(3)The requirement analysis and design of competition management system are described. The concrete business processes outline the main functions. The function requirements for six kinds of competition participants are analyzed by competition participants’ use-cases, competition managers’ use-cases, and review expert use-cases.System desing includes architecture design, function mode design and databases design. Among the core system models, management model of combinating test papers implement the system’s foundation data management for online testing, the one of online test implement the function of creating test paper and online testing, and the one of online evaluation implement the function of review expert selection, review task assignment, abnormal review data process and score statistics. The database tables in the system are detailed given out.(4)The implementation of competition management system are described. The development steps and relative codes of presentation layer and the persistence layer of entities are enumerated by the example of competition entity according to the architecture of networking testing and evaluation system. Main motheds and program flows in the networking testing model and networking evaluation model are implemented, for example, the program flow of test paper creation, online answering, and online submission of subjective answer for subjective questions. Some implement web page have been presented.This system has been adapted by Jiangxi Provincial College Student Contest of Mobile Software Design. The system design has been improved after application in the 2013 contest and 2014 contest. More than 30 universities or colleges, more than 1000 students and more than 60 teachers have used this system where the competition process has been developed smoothly, its real effect and adaptability have been tested and validated, and welcomed by many teachers and students. Not only has this system improved the positivity of student’s participating the competition, but also improved the efficiency and level, shortened ths completion period, saved many human, financial and material resources, enhanced the credibility of competition. In the future, mobilization management, socialization question-seting, socialization competition-taken, and socialization reviewing will be developed further.
