Research And Implementation Of Network Teaching And Learning Platform Based On DotNet

With the rapid development of education information technology and network technology,network teaching has become a hot field of education.It spans the limitition 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.Network teaching and learning platform uses advantages of network teaching to set up a virtual learning environment.It is a kind of software system,which provides full service for teaching-related work.The system should be able to provide comprehensive tools supporting online teaching and learning activities for teachers and students, shielding the complexity of program design and technical realization,lowering the threshold of teaching and learning activities,reducing the workload of teachers.So teachers can focus on the design of teaching contents,it stresses the learning way of self-study and makes collaborative learning as a supplementary mode to improve learning efficiency,ensures the quality of education and cultivates innovative talents of students.This thesis studies and designs a network teaching and learning platform based on.NET framework and Web technology.This platform uses constructivist educational theory as the guiding ideology,and realizes a network teaching and learning environment of easy communication and interaction.In this environment,teachers are leaders,students are subjects,coordination between them,which helps to promote students self-learning ability and collaborative learning ability.Based on requirements analysis in network teaching,the system uses B / S model of three-tier architecture, determining the basic functions of system.It builds part of software model of the system by using Software Engineering methods.It also designs a database and some functions of teaching,learning,assignment,examination,course answering and so on,and realizes the online examination system.Online examination system is an intelligent, open,multi-disciplinary,multi-level,general-purpose examination platform,which has a complete function,simple operation,strong interaction,and good practical value.The network teaching and learning platform uses Microsoft Visual Studio.NET 2005 as development tools,using C # as the main development language,using Microsoft SQL Server 2000 as a background database,and combining with ASP.NET technology and ADO.NET database access technology and so on.It is advanced both in principle and in technology to some extent.
