高校网络自主学习平台的设计与实现

中文摘要

随着知识大爆炸以及全国高校信息化的不断推进，学生获取知识的意愿更加强烈，途径更加丰富。传统的教学模式受到时间、空间、教师水平以及学生个性等因素的限制，已无法满足目前学生学习的需要。越来越多的国内外高校、研究机构以及学术团体等提出突破原有的教学模式的限制，充分利用Internet资源，为学生搭建一个自主学习的平台，鼓励学生提高自主学习意识，加强师生之间的交流，以便提高学生学习的效率和质量。

本项目以北华航天工业学院课程改革为背景，在分析国内外远程教育发展现状的基础上，经过详细的需求分析，提出了搭建高校自主学习平台的方案。本系统采用.NET作为开发平台，利用Sql Server2008数据库进行开发。系统功能上划分为四大部分：在线学习平台、在线交流平台和在线测试平台与后台管理。不同角色的用户拥有不同的操作权限。在系统开发过程中，充分考虑了系统的安全性和执行效率。

作为本项目核心参与人，全程参与了该项目需求分析、总体设计、详细设计以及系统实现等全过程。通过详细的需求调研和项目组讨论，完成了需求分析文档的撰写。在此基础上，通过使用功能结构图、DFD（Data Flow Diagram）数据流图、用例图（User Case）以及关系数据库设计等完成了系统总体设计以及详细设计。在.NET平台上，作者主要完成了在线学习平台、在线交流平台以及在线测试平台等模块的开发工作。

本系统操作简便、界面简洁美观，经过一段时间的上线测试，运行安全可靠，整体运行状态良好。在此平台上，师生之间加强了交流，提高了学习效率和质量，但有些功能有待进一步完善。

ABSTRACT

With the knowledge explosion and the National College of information technology continues to advance, the students acquire knowledge of the will more intense, way more abundant. The traditional teaching model is limited in time, space, teachers and students' individual levels and other factors, it has been unable to meet the current needs of students. More and more domestic and foreign universities, research institutions and academic organizations put forward to break out of the original teaching mode, make full use of Internet resources for students to build a self-learning platform to encourage students to raise awareness of autonomous learning, teachers and students to strengthen between exchanges in order to improve the efficiency and quality of student learning.

Based on the course reform of North China Institute of Aerospace Engineering and the analysis of the Education Development Project Status remote home and abroad, after a detailed needs analysis, we proposed to build a university independent learning platform solution. The system uses .NET as a development platform, using Sql Server2008 database development. The system is divided into four parts on the functions: online learning platform, online communication platform and online testing platform and back-stage management. Different user roles have different operating authority. In the process of system development, the security and efficiency of the system are considered.

As the core of the project, the author participated in the whole process of the project requirement analysis, overall design, detailed design and system implementation. Through the detailed needs of the research and the project team to discuss，the requirements analysis document is written. On this basis, the overall design and detailed design of the system is completed by using the functional structure diagram, DFD (Flow Diagram Data) data flow diagram, use case diagram (Case User) as well as the relational database design. On platform, the author mainly completed the development of online learning platform, online communication platform and online testing platform.

The system is simple to operate, simple and beautiful interface, on-line through a period of testing, safe and reliable operation, running in good condition overall. On this platform to strengthen exchanges between teachers and students, improve the learning efficiency and quality, but some features to be further improved.
