【摘要】 随着Internet的飞速发展，网络技术对教育领域的改革产生了重大的影响。现代远程教育作为新的教育模式正在建设和发展着，而网络作为教育环境一种新的载体，我们除了要探讨它对教育的技术支持，还要研究建立在它上的教学环境形态。本文通过对现代远程教育及其特点的研究，明确了要构建一个具有实用性又能跟上时代潮流的远程教育系统的业务需求。通过对远程教育业务关系的研究，构建出了远程教育系统的业务模型，明确了远程教育系统所要求的主要的业务流程。根据系统的业务模型构建了系统的框架设计模型和系统的数据结构模型，并进行了详细的设计，通过portal技术和其它相关技术，实现了系统的基本功能，达到了需求的目标。文中用统一建模语言UML(Unified Model Language)对系统进行详细分析，包括系统结构设计、数据库设计等。此外，本文还描述了系统实现过程中的一些关键技术。课题着重研究了远程教育支撑平台的需求特点和实现远程教育教学交互的设计方法，同时也对portal技术，现代远程教育的特点和在远程教育系统构建过程中的相关理论和技术进行了描述，并在研究的基础上又有了相应的应用。文章所建立的远程教育的业务模型具有一定的应用价值，设计的远程教育支撑平台完整，对教学交互的设计详细、具体，基于此构建的远程教育系统的功能已比较完善，并在UNDP403项目中得到了应用，达到了良好的远程教学和教学交互的目的。更多还原

【Abstract】 With the development of Internet, the network technology has a tremendous influences on education reform. Modem Distance Education(DE), as a new education model, is constructing and developing. We should research the morphology of the teaching environment upon it, besides exploring the network as a new education environment carrier and supporting technology for education. The paper, by the research of the modern DE and its character, is explicit about the sevice demand of the distance education system which constructs to having the usability to follow the trend of the times. By the research of the DE’s business relation, the paper constructs the DE system’s business model, and propuse about the primary service flow which the distance education system requested.The paper constructs the system frame design model and the system construction of data model according to the system service model, and design detaily. Based on the portal technology and other correlation technology, We have realized the system’s basic function, have achieved the demand goal. The paper analyzes the system with UML, and details the designs of the system, mainly including the system architecture, database and so on. Moreover, describes some key technologies to deploy the system.The paper emphatically studies the demand characteristic of the supporting platform for DE, and the design method to realize the collaboration of the teaching and learing in the DE. Simultaneously describes the portal technology, the modern DE’s character, the correlative theories and technology in the construction process of the distance education system. And has application on the foundation of research. The establishment of the distance education’s service model has certain application value, the design of the DE’s supporting platform is integrated. The desing of the collaboration of the teaching and learing is detailed and concrete, the DE system already has basic function, and has been applied in the UNDP403 project, has achieved the goal of distance education for teaching and learning.更多还原
