【摘要】：隨著云計(jì)算技術(shù)在教育領(lǐng)域的應(yīng)用越來越廣泛,教育開始進(jìn)入到云服務(wù)的時(shí)代。再加上移動(dòng)互聯(lián)網(wǎng)的快速發(fā)展,一些新型的基于服務(wù)的個(gè)性化的學(xué)習(xí)模式開始出現(xiàn),比如泛在學(xué)習(xí),這些學(xué)習(xí)模式的開展,都有一個(gè)共同的基礎(chǔ),都具有功能強(qiáng)大的資源平臺(tái)。傳統(tǒng)的資源平臺(tái)都是由平臺(tái)需求方自己建設(shè),這樣就導(dǎo)致平臺(tái)重復(fù)建設(shè)、投入成本高,并且不利于資源的共建共享。本文將云存儲(chǔ)等相關(guān)技術(shù)引入到資源管理平臺(tái)中,建設(shè)平臺(tái)和資源利用率高、投入成本低,并且支持個(gè)性化教學(xué)的資源平臺(tái)。本文在分析了面向個(gè)性化教學(xué)的資源平臺(tái)建設(shè)的理論基礎(chǔ)、技術(shù)基礎(chǔ)、平臺(tái)建設(shè)目標(biāo)和業(yè)務(wù)需求的基礎(chǔ)之上,采用面向服務(wù)的設(shè)計(jì)思想,提出了面向個(gè)性化教學(xué)的資源平臺(tái)的系統(tǒng)框架結(jié)構(gòu)。這種框架結(jié)構(gòu)將整個(gè)平臺(tái)分成三層,分別是應(yīng)用層、服務(wù)層和數(shù)據(jù)層。這種體系結(jié)構(gòu)不僅可以避免平臺(tái)的重復(fù)建設(shè)、降低成本,由于可以進(jìn)行個(gè)性化的服務(wù)定制,還支持用戶利用平臺(tái)開展個(gè)性化的教學(xué)。在對(duì)這種體系結(jié)構(gòu)進(jìn)行分析之后,詳細(xì)的介紹了面向個(gè)性化教學(xué)的資源平臺(tái)的功能模塊設(shè)計(jì)和部分模塊的數(shù)據(jù)庫設(shè)計(jì)。面向個(gè)性化教學(xué)的資源平臺(tái)有兩個(gè)關(guān)鍵的問題需要解決,分別是日志收集和個(gè)性化資源推薦服務(wù)。對(duì)于日志收集,提出使用開源的分布式的海量日志采集系統(tǒng)Flume NG來實(shí)現(xiàn)日志的收集,并且使用MongoDB來存儲(chǔ)平臺(tái)中復(fù)雜的日志信息；而對(duì)于個(gè)性化資源推薦,則選擇目前已有的并且非常適合平臺(tái)的一種個(gè)性化資源推薦模型,這種模型不僅可以為用戶推薦與用戶已有興趣相關(guān)的資源,還可以為用戶推薦新的感興趣的資源。論文采用Web Service相關(guān)技術(shù),對(duì)面向個(gè)性化教學(xué)的資源平臺(tái)進(jìn)行實(shí)現(xiàn),包括用戶管理、資源管理、課程管理和個(gè)人空間等主要功能模塊,并給出部分功能模塊的實(shí)現(xiàn)效果。目前該平臺(tái)已經(jīng)在華中師范大學(xué)內(nèi)部投入使用。
[Abstract]:With the application of cloud computing technology in the field of education, education began to enter the era of cloud services. In addition, with the rapid development of mobile Internet, some new service-based personalized learning models, such as ubiquitous learning, have a common foundation and powerful resource platform. The traditional resource platform is built by the demand side of the platform, which leads to the repeated construction of the platform, the high input cost, and is not conducive to the co-construction and sharing of resources. In this paper, some related technologies such as cloud storage are introduced into the resource management platform. The construction platform and the resource platform with high utilization ratio of resources, low input cost and supporting individualized teaching are introduced in this paper. On the basis of analyzing the theoretical foundation, technical foundation, platform construction goal and business requirement of the resource platform construction for individualized teaching, this paper adopts the service-oriented design idea. The system framework of resource platform for individualized teaching is presented. This framework divides the whole platform into three layers: application layer, service layer and data layer. This architecture can not only avoid the repeated construction of the platform and reduce the cost, but also support users to use the platform to carry out individualized teaching because of the individualized service customization. After analyzing this architecture, the function module design and database design of resource platform for individualized teaching are introduced in detail. The resource platform for individualized teaching has two key problems to be solved: log collection and personalized resource recommendation service. For log collection, Flume NG, an open source distributed massive log collection system, is proposed to realize log collection, and MongoDB is used to store complex log information in the platform. A personalized resource recommendation model, which is currently available and very suitable for the platform, is selected. This model can not only recommend the resources related to the users' interest, but also recommend new resources of interest to the users. In this paper, Web Service technology is used to realize the resource platform for individualized teaching, including user management, resource management, curriculum management and personal space, and the effect of some functional modules is given. At present, the platform has been put into use inside Huazhong normal University.
