【摘要】 随着教育的发展和信息技术的进步,教育教学与信息技术不断融合,极大促进了高校的教育信息化建设。一直以来,建设教学资源都是实现教育信息化的基础工作,也是需要不断维护和完善的工程任务。以往教学资源的建设与管理,需要大量精力对其进行更新和维护。并且各高校独立开发,没有建立统一的教学资源共享平台。同时限于教学资源固有的多样性和复杂性,不同的开发人员对教学资源的理解不尽相同,导致建立许多属性不同、分类边界不清的教学资源模型,大大增加了管理教学资源的难度。因此,建设通用性、可扩展性、可重用性良好的教学资源管理平台显得尤为必要。本文通过对教学资源管理平台的功能需求进行分析,并且在充分考虑架构的可重用性和扩展能力的基础上,设计了重用性高、扩展能力良好的教学资源管理平台架构。参考《教育部教育资源建设技术规范》中对教学资源的范围界定和数据模型,提出了教学资源管理平台中主要资源的信息模型,包括属性和接口方法,并且分析了平台中信息模型之间的关系,给出信息模型关系图。除了平台架构和信息模型的设计,本文还介绍了教学资源管理平台的关键技术。通过介绍教学资源的上传流程、教学资源的分类存储方法以及教学资源检索方式,展现教学资源管理平台的关键业务流程。针对不同教育结点,提出了分布式优质教学资源的发布、共享和同步机制。由于本平台还支持通过云桌面对平台使用进行培训,本文还提出了基于伺服的多虚拟机统一管理技术,实现培训平台的个性化定制任务。最后,本文采用SSM框架实现了B/S架构的教学资源管理平台,展示了平台基本功能和依据关键技术设计的相关功能,验证了平台架构、信息模型和关键技术设计的合理性,为教学资源库建设提供良好借鉴意义。

【Abstract】 With the development of education and the advancement of information technology,education and information technology continue to merge,which greatly promotes the construction of educational information in colleges and universities.All along,the construction of teaching resources is the basic work of realizing education informationization,and it is also an engineering task that needs to be constantly maintained and improved.In the past,the construction and management of teaching resources required a lot of energy to update and maintain them.Because of the independent development of colleges and universities,there is no unified platform for sharing teaching resources.At the same time,due to the inherent diversity and complexity of teaching resources,different developers have different understandings of teaching resources,resulting in the establishment of many teaching resources models with different attributes and unclear classification boundaries,which greatly increases the difficulty of managing teaching resources.Therefore,it is especially necessary to build a teaching resource management platform that is versatile,scalable,and reusable.Based on the analysis of the functional requirements of the teaching resource management platform and the full consideration of the reusability and scalability of the architecture,this paper designs a teaching resource management platform architecture with high reusability and good expansion ability.With reference to the scoping and data model of teaching resources in the Technical Specification for Education Resources Construction of the Ministry of Education,this paper proposes an information model of the main resources in the teaching resource management platform including attributes and interface methods,analyzes the information models in the platform,and gives the relationship diagram of the information model.In addition to the platform architecture and information model design,this paper also introduces the key technologies of the teaching resource management platform.This paper presents the key business processes of the teaching resource management platform by introducing the uploading process of teaching resources,the classification and storage methods of teaching resources,and the retrieval methods of teaching resources.According to different educational nodes,the mechanism of publishing,sharing and synchronizing distributed high-quality teaching resources is proposed.Since the platform also supports training of platform usage through cloud desktop,this paper also proposes a technology for uniformly managing multiple virtual machines based on servo to realize the personalized customization task of the training platform.Finally,this paper adopts SSM framework to realize the teaching resource management platform of B/S architecture,demonstrates the basic functions of the platform and related functions based on key technology design,and verifies the rationality of platform architecture,information model and key technology design,which provides a good reference for the construction of teaching resources.
