Design And Implementation Of A Paperless Examination And Scoring System

Examination is the important means checking a student's knowledge and ability. Along with information technology's progressing by leaps and bounds, the traditional examination way reforms unceasingly, already developed from the computer auxiliary examination to the paperless examination, but now there are related to the paperless examination system still exist: standards are not unified, narrow the scope of application, Fewer features, the use of trouble, design owed to the inadequacies of the science.This thesis through has conducted the widespread thorough research to the existing similar function's system, in view of the existing insufficiency and limitations, the design has developed a set of paperless examination and scoring system, supports many kinds of topics, confidentiality strong, is suitable for work and so on overwhelming majority test, evaluation, practice, competition, realized from inducted the essential data, to decide the plan, to set the questions, organization examination paper, the register, to arrange the examination place, receiving and dispatching examination paper, the monitoring, the evaluate examination papers, to ascend divides the statistical analysis entire process the intellectualization and the automation. And to this system's application prospect, system's main research content, the main theory which and the correlation technique as well as in the system used has carried on the detailed elaboration, including system's architecture and development kit's selection proof, system design, database design, automatic scheduling the examination room, automatic organization examination papers, automatic grading as well as test question appraisal and so on each aspect.This thesis mainly proposed and designs realizes below had the innovation and the usable aspect:①In order to improve the system of multi-user operating at the same time with the ability to reduce the server load and enhance the security system. Proposed and implemented a three-tier C/S and B/S mixed architecture design, distributed in different layers on the machines, the database server and the invigilator for the dual-use data synchronization backup. Proposed the data gradient graduation transmission method, before realizing the test, the examination paper to distribute first from the school server to each examination place monitors an exam machine, then from respectively monitored an exam machine distributes separately gives various examinees. ②Realized the answer paper data security, the examinee answered a topic every time, the data preserves automatically monitors an exam machine and the backup monitors an exam machine, has solved the answer paper data missing which, because the hardware fault created.③Realized support many kinds of duplicate miscellaneous problems online to set the topic and the question bank management function.④To the Senate associated with the existing management system for data sharing, proposed and implemented to use more generic Excel documents as an intermediary, and the school, and other basic data import and export results and other data.⑤Realized has assigned the examinee regarding the central test take the class as the unit, regarding the dispersion-like test, let the student through the website online register.⑥Achieved a smart organization examination papers feature, and gives the algorithm. Test Paper also raised the quality of the assessment method.⑦To achieve the automatic scheduling the examination room functions, and gives the algorithm.⑧Not only to achieve the objective that the automatic function score, also proposed that the subjective automatically score the design, and gives the realization of the process. Questions on the part of subjective function automatically score the achievement.
