【摘要】 随着网络技术的高速发展，以网络为媒介的分布式远程教学正在走出传统教学的框架，逐步改变了“教”与“学”的方式。基于Web的远程教学已成为一种新的教学模式。本论文重点讨论了基于Web的远程教学系统的设计和实现。 论文涵盖了远程教育的多个研究领域，包括建构主义学习理论、自适应测试理论等。从Web的软件实现技术角度，论文讨论了远程教学系统的总体结构设计，并介绍了实现该教学平台采用的关键技术，例如数据库、B／S结构模型、Web服务、ASP．net等。 本论文详细论述了系统结构的设计与实现，系统各功能模块以及各部分数据库的设计和实现。系统集成了网上学习、网上自适应考试、网上答疑、网上课件管理等模块。该系统构建了一个交互式的远程教学平台。学生在数字化环境下进行交互式学习。指导教师根据系统的反馈信息指导教学。因此，本论文为在线远程教学系统提供了较为完善的解决方案。 本论文着重论述了B／S结构模型的优化技术，该技术使得Web页面中的HTML编码和业务逻辑得到有效分离。并且论述了使用Web服务构建远程教学系统的方法。而且介绍了自适应考试系统的实现。这些技术在其他项目实施中也有一定的借鉴作用。更多还原

【Abstract】 With the high-speed development of network techniques, the distributed modern distance education with the medium of network is going out of frame of the traditional education, which is changing the form of "teaching" and "study" . The distance education based on Web has been a new teaching method. This thesis focuses on the design and implementation of a distance education system based on Web.The thesis covers several research aspects in distance education, such as constructionism and adaptive test theory, etc. From the perspective of Web-based software development, this thesis mainly discusses the ensemble architecture design of the distance education system. Besides, it also introduces the key technology used on this Web education platform, such as the database, the structure model of B/S, Web service, ASP.net, etc.The thesis discusses the design and implementation of the system structure as well as of the functional models and database bank of the system in detail. The system consists of sorts of modules, such as on-line learning, on-line adaptive test, on-line question and answer, on-line management of courseware, etc. The system builds an interactive distance education platform. Students interactively study under the digitization environment. And instructors teach with useful feedback from the system. Therefore, it offers a relatively completely solution for on-line distance education based on Internet.This thesis emphasizes the technology of optimizing the structure model of B/S, which separates the HTML programming from the commerce logic, as well as the technology of Web service, with which the distance education system Web-based is built. Besides, the thesis also introduces the implementation of the adaptive test. These can use for reference in other projects.更多还原
