Design And Implementation Of Mathematical Self Testing Evaluation System Based On Java

With the development of technology, now in the process of teaching in schools,more and more using a variety of computer technology and multimedia to assist inteaching, and the teaching of mathematics is often more boring, conducted viacomputer-assisted instruction, allowing students more deeply understanding andmastery of mathematical knowledge, and teachers for each student’s understanding ofspeech is limited to the classroom, the usual assignments and exams, these reactions cannot fully understand and evaluate student mastery of knowledge, mathematicalknowledge is not simply by assessment to reflect once or twice, the need for multipleassessments, and online self-test to assess the mathematical system just to make up forthis deficiency, through self-test, allowing students to understand their own grasp of theextent of knowledge, teachers can also be based on students learn self-test result of theinadequacies of a student, you can understand the general issue of the existence of thestudents, in turn, can be changed according to the self-test results edges usual teaching,more targeted teaching work, a significant improve the quality of teaching.This thesis is to address the problem, an online self assessment system as the mainobject of study, in-depth analysis of the current popular web development framework,application servers, and database access technology, based on the online self assessmentsystem has been implemented detailed discussion and research. The main contents are:1. Studies based on J2EE web application development technologies, proposed touse the Model View Controller (MVC) architecture for application development, thisstructure will be divided into three tiers of the entire application, so that the level of thewhole system is relatively clear, ensure that the system developed when comparing fast,at a later stage during maintenance, can easily be maintained and expanded.2. Research different application servers, proposed to use Tomcat as the applicationserver, the application server is an open source project, to avoid copyright issues, whilethe application server for small to medium applications should be more than enough, thehardware requirements are not very high, both to ensure server performance, but also tomeet some of concurrent system requirements.3. Research online self assessment system the entire business process, we proposea generic access control theory, the access control by defining menus, function points, roles, and users, by defining menus, the system can be carried out later add or deletefeatures By defining the function point, the roles of each user belongs to authoritycontrol, which greatly improves the overall access control flexibility.4. Research online self assessment system the entire business process, we proposea flexible approach designed to modify the papers. Methods Exam maintenance,maintenance of the subject classification by defining rules that generate paper andflexible generate different papers, papers generated and can be finished modified again,fully meet the actual needs of the teaching process.
