Network-assisted Teaching System Research And Design

Along with the development of network technology, remote education has been developed and popularized rapidly. It is an important task to solve urgently how to construct a new mode of studying, which is very conventional and not restricted by place and time. The wide-range application of modern network-based instruction system stands out the learner's main body role in the activities of teaching and learning on the net. As a representation of modern education, web-based instruction,which optimized the educational resources and reformed the traditional education ideas and techniques, has been the trend of the modern education. Web-based instruction can't actualize very well without an efficient management platform. It is a urgent demand to construct a web-based instruction system based on web.In this paper, the auther focuses on the characteristics of network teaching system, Understood the system development present situation and the importance,Adapted the use of the MVC design pattern, UML modeling language, With J2EE platform technology as the foundation.Then, put forward the basic thoughts based on Java Servlet, JSP, JavaBean technology modular Web program and B/S multi-layer system of development. From the service demand, the module function demand, the performance demand and so on three aspects, separately to the system in the teacher,the student and the manager three kind of role's architectures and the function have carried on the analysis. From the presentation layer, WEB layer,business layer and data layer logic layer of four carried out the specific design and implementation for the network teaching system optimization software provides a viable framework for.And introduced some of the data table structures and relationships between tables, using the database connection pool technology ,for the purpose of optimizing system data to ensure that multi-user access request,meanwhile,to meet the user on--line learning and Q&A needs.As the same times,basing on the introduction and analysis of the test organization algorithms, this thesis implements a new algorithm, which can meet the need of multiple parameters requirements. On the basis of a summary review of the development of teaching resource database, the integrable ware idea and the phylogeny of integrable ware system were introduced. Then the construction of the network source database system was presented, in which the system structure, overall design of the system, management system and function realization were emphasized.
