B / S-based Network To Learn The Design And Realization Of The Examination System

With the rapid development of information technology in education, online education has changed the traditional education mode of learning. Traditional teaching requires that the focus is the teacher not the student. The teacher faces to all students and is the guide for the learning of students. Network learning focuses on the student. It may be at any time and place for learning. It can be identified according to their own learning style, learning pace and it can also know the situation of learning according to the need for independent testing. Network learning can develop more initiative, flexibility than the traditional teaching. It can realize personalized learning and develop students self-learning ability. It is the complementary with the traditional model to realize the quality-oriented education. At the same time, our college's computer network theory course was the excellent course of zhejiang province in 2009, so it is necessary to create the computer network learning test system based on B / S structure which provides a good platform for students testing knowledge of computer networks.This thesis firstly analyzes the research background of network learning system, and proposes the concept of online education, introduces the research status at home and board, the issue of content and significance. It describes the relevant technologies involved Learning test system, such as the B / S architecture, ASP.NET technology and ADO.NET database access technology, and SQL Server 2005.Then this thesis describes the overall objective, the design objective, the design principles of system. It explains the system 3-tier application software structure and system users by the methods of graphs, and then it elaborates the system modules and functions. Finally it interprets the system database design and system security. In the database designing it shows the concept of the database structure design by the E-R diagram and shows the model of the database by tables.Finally, it shows the detailed realization process of each module of network learning testing system in the form of diagrams and code.It provides a scientific effective implementation scheme based on B / S for the computer network system. This system achieves the learning from the point to a plane, from the plane to the three-dimensional. It is an Internet-based learning system which aims at the teachers and students and achieves individual learning and associates the case study with interactive learning in a collaborative...
