【摘要】 随着高等院校规模化招生,我国高校教育已经进入了大众化教育阶段,教育质量成了社会普遍关注的热点问题。为了提高教育质量,完成高校课程的转型与升级,各高校开始加强精品课程建设,建立精品课程网站是提升精品课程建设水平的有效途径。精品课程网站建成并运行,既丰富了教师的教学方式、增加了学生学习趣味性和主动性,又提高了高校教育质量。但是,同时也存在一些问题,例如:网站的交互性不强、更新缓慢等。杨凌职业技术学院《商务网页设计与制作》精品课程于2010年被评为省级精品课程。但是,用户在使用该课程网站的过程中发现其存在交互性不强、教学辅助功能薄弱等问题。本文以该精品课程网站为基础,构建基于WEB的精品课程教学辅助系统。借助该系统中的课程资源共享、教学互动和效果评价新功能,来丰富教学手段,增强学生自学能力,提高教育质量。为建立该系统,本文采用“B/S”三层体系架构,使用Photoshop、Dreamweaver设计友好界面,Tomcat作为Web服务器,Microsoft SQL Server 2008存储数据,采用Spring+Hibernate完成系统的设计。本文主要研究内容如下:(1)通过开展详细的系统分析,最终确定了系统功能。(2)基于J2EE技术体系构建系统架构,设计了系统功能、数据库概念模型和数据表关联模型。(3)基于B/S架构设计并实现了基于WEB的精品课程教学辅助系统,实现了系统的用户管理、作业管理、留言管理、考试管理等功能。(4)采用改进遗传算法完成试题组合,提高了试题组合多样性,减少试卷重复率,降低系统代码维护成本。(5)采用白盒与黑盒测试法全面测试了系统代码、系统功能和系统兼容性。经过测试发现系统运行稳定、可靠,达到了本文的预期目标,有一定的实用性。更多还原

【Abstract】 With the large-scale enrollment in colleges and universities, higher education in our country has entered the popularization education phase. Therefore, the quality of education has become a hot issue of common concern. Various universities began to strengthen the construction of high-quality course in order to improve education quality and to complete the transformation and upgrade of the university course. An effective way to promote the construction of high-quality courses is to establish a high-quality course website(HCW).As a novel teaching method, HCW not only increases the students’ learning interest and initiative, but also improves the quality of university education. However, there are still some problems in HCW, such as poor website interaction and slow updating. The HCW named“Business web design and production” in Yang Ling Vocational Technical College was awarded provincial-level excellent course in 2010. However, users found some problems in this HCW, namely, poor website interaction and weak teaching assistance function. Aiming at these problems, this thesis establishes the web-based HCW teaching assistant system. With the help of the new functions, i.e., curriculum resource sharing, teaching interaction and teaching effect evaluation, this system can enrich the teaching methods, enhance students’ self-study ability, and improve the quality of education.The design pattern of the system is the popular “J2EE Web of Spring MVC +Hibernate”. The system is composed of "client/server" three-tier architecture, friendly interface designed with Photoshop and Dreamweaver, Tomcat as Web server,Microsoft SQL Server 2008 as data storage. The main contents of this thesis are as follows:(1)The functional requirements of the system is determined after detailed analysis.(2)System architecture is constructed using J2 EE technology, system conceptual model and datasheet association model are established.(3)The web-based HCW teaching assistant system, with user management, assignment management, message management and examination management functions, is designed and developed based on the B/S architecture.(4)The improved genetic algorithm is used to complete the combination of the test paper, which improves the diversity of the examination paper, reduces the repetition rate ofthe test paper, and reduces the maintenance cost of the system code.(5)The system code, system function and system compatibility are tested using white box and black box testing method.After the test, it is found that the system is stable and reliable, which meets the expected goal of this thesis, has certain practicality.更多还原
