【摘要】：在线学习(Learning Onlin e,LO)是通过在网上建立教育平台供学习者学习的一种方式。它实现了学习者能随时随地接受教育的要求,打破了传统教学中对时间和空间的限制。随着在线学习方式的深度普及,其主要支撑环境一在线学习平台逐渐曝露出平台建设各自为政、区域教育信息化资源分布不均、学习平台间存在信息孤岛等问题。云计算的出现为有效地解决这些问题提供了一条可能的途径。云计算由大量计算机群落组成,通过分布式计算和虚拟化技术将软、硬件资源虚拟化成一个统一的资源池,以免费或按需租用的方式向用户提供计算、存储等服务。目前比较成熟的云计算平台拥有百万台服务器组成的服务器集群,能够提供强大的计算能力和海量的存储空间。本文结合云计算的服务与特点,提出了基于云计算构建在线学习平台的研究方案,并在已有的云计算平台上利用^u发一个统一、开放的在线学习系统,旨在改变传统在线学习平台建设中存在的不足。具体工作主要有:第一,对在线学习和云计算等相关理论、的核心架构以及其提供的接口服务技术进行了研究与分析;第二,对传统分散式构建在线学习平台的模式进行详细剖析,针对其存在的弊端,结合云计算的优势提出了基于云计算构建在线学习平台(简称云学习平台)的研究方案,并对整个云学习平台的体系架构和功能需求进行了分析和设计;第三,利用开发平台、集成环境、技术开发了在线学习系统的主要功能模块(用户管理、学习资源管理以及互动交流等并对系统功能界面、业务逻辑、数据持久化和系统安全等细节的具体实现进行了分析和阐述。通过运用开发平台以及技术,本文基于云计算实现了在线学习系统的主要功能模块,为基于云计算构建在线学习平台的可行性提供了一定的依据。
[Abstract]:Online Learning Onlin (LOL) is a way to set up an educational platform on the Internet for learners to learn. It realizes the requirement that learners can receive education anytime and anywhere, and breaks the limitation of time and space in traditional teaching. With the popularization of online learning mode, its main supporting environment, the online learning platform, has gradually exposed the problems of its construction, the uneven distribution of regional educational information resources and the existence of isolated information islands among the learning platforms. The emergence of cloud computing provides a possible way to solve these problems effectively. Cloud computing consists of a large number of computer communities, virtualization of software and hardware resources into a unified pool of resources through distributed computing and virtualization technology, providing computing, storage and other services to users in a free or on-demand way. At present, the more mature cloud computing platform has a server cluster composed of millions of servers, which can provide powerful computing power and massive storage space. According to the service and characteristics of cloud computing, this paper puts forward the research scheme of building online learning platform based on cloud computing, and sends a unified and open online learning system on the existing cloud computing platform. The aim is to change the deficiency in the construction of traditional online learning platform. The main works are as follows: first, the core architecture of online learning and cloud computing, as well as the interface services provided by them are studied and analyzed. This paper makes a detailed analysis of the traditional mode of constructing online learning platform. In view of its disadvantages and combined with the advantages of cloud computing, this paper puts forward a research scheme of constructing online learning platform based on cloud computing (referred to as cloud learning platform). The architecture and functional requirements of the whole cloud learning platform are analyzed and designed. Thirdly, the main function modules (user management) of the online learning system are developed by using the development platform, integrated environment and technology. Learning resource management and interactive communication are also discussed in detail, such as system function interface, business logic, data persistence and system security. By using the development platform and technology, this paper realizes the main function modules of online learning system based on cloud computing, which provides a certain basis for the feasibility of building online learning platform based on cloud computing.
