| With the development of computer technology, Internet culture has gradually infiltrated into all areas of our lives, the Internet access to information gradually becomes the main channel for us, which also brings to the education more room for developmentTraditional teaching methods is just like that the teachers and students gathered in a classroom space, relying on the podium, blackboard as the main teaching methods, there have some limitations for the face to face educational methology. advances in technology brought about changes to Internet-based distance education mode, which come to vision of people's quest for knowledgeIn Chinese traditional system of distance education, correspondence education, radio and television education, self-examination, there exsits an old- fashioned technical problem, still need to communicate face to face Which can not achieve real sense of "remotion". Internet technology, computer technology continue to improve and provide advanced technical support for the sake of breakthrough the time limit. The multimedia form should be adopted to construct the entire education system on the internet. regardless of anyone, in any place or any time can acquire the knowledge what they need. The highlighting feature of the Modern distant education is "remotion" and "interaction" .To establishing a network platform, enabling the students living in different geographical environments, teachers, through the network link, in this virtual classroom, "Listening," and "Speaking", "Reading", "Writing." With each other in real-time or non real-time exchange of knowledge and the formation of collaborative learning model to explore the issue with each other and feel the same as in the classroom. Sufficient to improve student learning initiative to enhance the study's confidence. A variety of practice has proven that learners are already receiving and endorsed by this social-oriented distance education mode.This article The Realization of Long Distance Education Based on NET. Technology mainly deals with the set up of a small type long distance education system which relies on web developing technology ASP. NET offered by Microsoft company. ASP.NET is the main application of Microsoft.NET technology and is also popular in Web application and development. It supports Web technology, sets program structure in common mediate language and Web application program in any Web servicer. ASP.NET designs the interface by controls, adding model closing to servicer , to make it easier and concrete in a way closing to Windows program model. Programmer uses many spaces to set the attributes of controls and design codes to complete the set up of Web program .ASP.NET offers stable quality and brings in the concept of program collectives which can share the codes in application program .It can also visit various data source swiftly and effectively by using ADO.NET and support several translating languages.The back data base uses SQL Server 2008, which is a popular database nowadays. SQL Server 2008 database engine, which integrated support for XML, scalable, and easy to use and install, with the network are linked closely together, is the database device which building a good Web site. At the same time, to use ADO.NET database access technology, establish a connection between application and database.Distance education is based on the Internet, for different geographically dispersed users. System uses the B / S that is the browser / server mode, which is a comprehensive support network systems built, users typically only need to have operating system and browser to achieve a rich and lively expression, and simple, easy communication.To build a collaborative teaching between the network system, distance education aimed at creating full-featured, rich resources of online education platform for teachers and students .Through the establishment of different functional modules, among them complement each other and complement each other, to achieve long-distance teaching purposes. In the system environment, provides students with a large number of learning materials, exchange and cooperation, making interaction between teachers and students to achieve the network to develop students self-learning initiative. The system designs two kinds of users and permissions, for students'users and teachers'users, the user's identity according to their choice of the correct user type into their main interface.When enter the main interface, students may view the individual's basic information, and revise the wrong message. Students can obtain the latest teaching and learning of information first time through the bulletin board the first time to. Choose to study courses, access to elective cases link to obtain basic information for all courses, such as: course name, instructor, course credits and so on, while you click on the appropriate link to view the instruction of teachers can be the basis of information; The main elements of introduction, understanding of the course is mainly to pass the knowledge areas, which applications. The needs of the students selected according to their own course, you can enter the online learning phase. This section is based on the core network courseware using multimedia teaching content in the form of display. Make full use of text, video and other multimedia resources, and vivid visual presentation of teaching content in front of students. Courseware arrangements are based on sections of the course design; students can be teachers to the teaching of thinking in order to learn, but also according to the need for focus on learning. The learning process, you can interface through the Q & A with the teachers and students to communicate. In the end, the online exam can test their knowledge and grasp of the situation.So is the lecturer user, who can modify his or her personal information, setting important courses for students to choose, issuing relevant studying material ,assigning homework ,communicating with students on line, deciding tests database according to the content of subjects which are to testify the grasp of knowledge of students and offering reference for course design. In order to fulfill the tasks, tables of relevant databases has been set, which include table of students'information, lecturers'information, courses'information etc. And also the instructions for the attributes of tables and the type of data are available.The Long Distance Education is set to offer platform for teaching and resourceful teaching stuff , sharing the teaching resource by various Internet technologies and methods of multimedia. |
