【摘要】 随着计算机网络技术与多媒体技术的发展, 远程教育已经成为改革传统教育模式的强大动力和有效手段。它突破传统学校教学方式的时空束缚,与课堂教育、广播教育、电视教育共同构成多元化的教育体系。一个人只要有一台计算机和接入网络的设备,就可以随时进行学习与培训。跟其他教育模式相比,远程教育具有时空自由、资源共享、系统开放、便于协作等优点。然而目前大多数远程教育系统还不兼容的,存在教学资源的共享与互操作等问题,造成了资源的大量浪费。远程教育信息技术标准的提出和制定可以很好地解决上述问题。远程教育技术标准是一系列的技术规范和实践指南,规定教学系统抽象的框架结构和各个可能组成部分的属性、格式、接口、通信方法以及学习资源的格式、使用方法,为教学系统中的软件构件、工具、技术和设计方法提供指导。按照远程教育技术标准设计实现的远程教育系统,有相同的教学资源格式、数据传输和消息传输的通信协议、学习者模型和学习过程记录方式,极大地推动了远程教育的发展。本论文在研究远程教育标准体系和标准参考模型的基础上,详细分析了与学习管理系统LMS(远程教育系统的核心部分)相关的IEEE 1484 标准体系、ADL SCORM 规范、IMS 规范以及我国远程教育技术标准CELTS,设计并实现了基于标准的学习管理系统。本系统采用Java、COM 组件、XML 等先进技术开发,具有以下功能:导入符合标准的学习内容,这些学习内容可以由任何开发工具开发;根据学习者身份,自动导入其学习进度进行学习;自动跟踪记录学习过程、学习结果等,根据学习记录控制学习的进度;指导者可以查看学习者的学习过程、分数及学习中问题的记录,根据记录给予指导;学习记录的格式符合标准,能够与其他学习管理系统共享等。本论文还研究了把学习资源组合成符更多还原

【Abstract】 With the development of computer network technology and multimedia technology, distance education has already become strong motivity and effective means of reformation of traditional education. It breaks through the space-time limit, building up a pluralistic education system together with classroom education, boradcast education and video education. With one computer and equipment of access network, a person can study and train at any time. Compared with other education pattern, distance education has many advantages, such as free of space-time, sharing resourse, opening system, easy to cooperation. But now many distance education systems are incompatible, which has made troubles to resource sharing and cooperation. Puting forward and establishing distance education technology standardization can solve above-mentioned problems well. Distance eduction technology standardization is a series of technical specifications and guide, regulating the architecture of education system and offering guidance for software component, tool and design method in the education system. The standard-based distance education system has the same resource format, communication agreement of data transmission, learner model and learning recording mode, which has promoted the development of distance education. After studing a large number of distance education standardization system and referrence model, we have done deep study on standards related to learning management system which is the core of distance education system. These standards are IEEE LTCS 1484, ADL SCORM, IMS and CELTS. This system has the following functions: First, import the learning contents according with LMS standard, these learning contents can be made by any development tools. Second, the students’ registration and management, based on student’s identity, channel into its study schedule and study automatically. Third, the teacher’s registration and management, teachers can look over the record of the mark, study and questions in learning process, write guidance. Forth, Automatic track and record learning process, result of studying, etc., control the study progress. Fifth, the form of study record accord with norm, can share with other learning management systems. We have also studied the making and packaging of the learning content. Finally carried on the self-disciplining test of ADL to the system, the system passes second test. Nowadays, the learning management system based on distance education standardization has developed successfully, but the specification will be perfect continually. The application of standardization needs to be developed along with the specification.更多还原
