【摘要】：当前,网络教育越来越受到各国的教育科学者的重视,在整个网络教育应用中最为核心的部分就是教学资源库。但是大多数教学资源库都面临一些挑战,这使得从事教育相关的人士难以设计出与实际课程相符的教学课件,在这样一个大的背景环境下,教学资源如何进行统一维护与管理、资源库中的资源如何进行快速检索以及多个支撑平台间的资源如何进行调用已经成为摆在从事教育的相关人士迫切需要面对的一个问题。结合我校实际教学中暴露出的问题,本文考虑到统一管理与整合相关的教学资源,首先提出了一种基于J2EE架构教学资源库管理系统。该系统采用当前软件开发的主流框架——Struts,并利用了分层结构的MVC模式优点,对软件架构进行了一个清晰而具体的设计。其次,通过对教学资源库进行数据分析与跟踪设计,针对不同权限用户的不同需求实现各式各样的资源展示形式。最后,调用Lucene搜索引擎工具包对教学资源库进行全文检索。本系统在信息化校园环境的建设下,能够实现对教学资源的科学化管理与统一维护调用。同时,在未来的网络教学教学时间中该教学资源库也具有潜在的应用价值。教学资源库管理系统的开发与设计,将有效地提高我学院教学效率和教学质量,对实现优秀教学资源的共享、提高科研水平与促进高校的教学改革将起到非常深远的作用。同时,对于进一步促进教师进行深入的课程体系,教学思想、教学方法等相关内容的改革具有重要的科学意义。
[Abstract]:At present, the network education is paid more and more attention by the educational scientists of all countries. The core part of the whole network education application is the teaching resource bank. However, most teaching resource banks are faced with some challenges, which makes it difficult for people engaged in education to design teaching courseware that is consistent with the actual curriculum. Under such a big background, how to maintain and manage teaching resources in a unified way. How to retrieve the resources quickly and how to transfer the resources among several supporting platforms has become an urgent problem for the relevant people engaged in education. Combined with the problems exposed in the actual teaching of our university, this paper takes into account the unified management and integration of related teaching resources, first of all, a teaching resource database management system based on J2EE architecture is proposed. This system adopts Struts, the main frame of software development, and makes use of the advantage of MVC mode of layered structure, and designs the software architecture clearly and concretely. Secondly, through the data analysis and tracking design of the teaching resource database, a variety of resource display forms can be realized according to the different needs of users with different permissions. Finally, the full text retrieval of teaching resource library is carried out by calling Lucene search engine toolkit. Under the construction of information campus environment, the system can realize the scientific management and unified maintenance of teaching resources. At the same time, this teaching resource bank also has the potential application value in the future network teaching time. The development and design of the management system of teaching resource bank will effectively improve the teaching efficiency and teaching quality of our college, realize the sharing of excellent teaching resources, improve the level of scientific research and promote the teaching reform in colleges and universities. At the same time, it is of great scientific significance to further promote the reform of teachers' in-depth curriculum system, teaching ideas, teaching methods and other related contents.
