The Design And Implementation Of Television University's Network Teaching Platform Base On .NET Technology

With the rapid development of education information technology and network technology, network teaching has become a hot field of education. It spans the limitation in time and space, breaks the traditional model in classroom teaching. Because of the characteristics of sharing educational resources and powerful interactive capabilities, it is well favored by all ages of teachers and students.The implementation of teaching needs the support of an efficient network teaching platform, which should be user-friendly. The platform is the use of educational technology and network technology with the theory of the ideological education by building networks of the teaching environment, for teachers and students in teaching and learning activities provided online support tools, and to shield complex technical realization process, make teachers can concentrate on teaching students through its autonomy in the learning process, exchanges, and testing, and from the restrictions of time and space.This thesis introduces the developing trend and research of network teaching platform, analyzes its existing problems and there causes. A network teaching platform is designed to meet the needs of teaching in Shandong Radio & Television University, The platform's full support for all aspects of teaching, including the sharing of teaching resources, courseware release, online exchanges, and offline business, and online testing, and other course question-answering integrated teaching services. With the tool of UML, a student-centered use case model of teaching and learning system is designed, separately to the system in the manager, the teacher, the student three kinds of role's architectures and the function have carried on the analysis. According to software engineering theory,.a series of designs are developed, such as system architecture, overall system function and database. Management of test and online testing are introduced. At last, problems in and prospect about platform development and application are put forward. The platform is designed by based B/S three-tier system, Windows Server 2003, IIS 6.0 and ASP.NET. The database of SQL Server 2005 is used, Asp.net front-end development tools is Visual studio.net, which makes it advanced to a certain degree theoretically and technically.
