Fujian Science And Technology English Course Network Teaching System In The Job School Design And Realization

At present, the domestic vocational institutions are actively exploring teachingreform, information technology, network into teaching in vocational schools in order topresent the main direction of reform. Relying on the Internet for online education, thereare unique advantages of information technology, and compared to other forms ofeducation, online teaching to break the limitations of time and space, makingeducational resources in the world, where the network can easily get there, it will be thetraditional teacher-centered teaching mode single impart to modern network technologyas the basis of various teaching paradigm shift, give full play to the initiative of studentlearning, to stimulate the students potential, to cultivate students’ creative thinking toprovide favorable conditions.The development of the project in Fujian Science and Technology NetworkTeaching Vocational English as a background, the full research network teaching needs,designed by " listening, speaking, reading and writing," focusing on four aspects ofnetwork teaching system. Construction method of software engineering for systemrequirements, design of the user login module, resource sharing module, discussionsmodule, the administrator module, online examination module and English radiomodule lays out the system work flow chart of each functional module, theestablishment of conceptual data model. Overall system uses B/S architecture, isdesigned to adapt to the network environment to run. In the actual development process,the three-tier MVC framework to design and develop the conceptual model of the datais converted to the actual database design, selection of Microsoft’s Visual Studio.NET2008as a development tool for Microsoft SQL Server2008database as the backendsupport, combined with ASP.NET technology and ADO.NET database accesstechnology to achieve coding. Also, because the system to run on the Internet, forenhanced security specifically designed to build a SQL injection attack prevention,anti-XSS attacks, anti-upload vulnerability and four anti-ARP hang horse protectionsystem and improve the overall stability of the system to ensure that the system meetsschool English courses online teaching needs.In the realization of the system, the paper also carried out on the system to run testsdistinguish between functional testing, stress testing and system testing page. Among them, the function test is used to determine whether the system can follow each moduledesign features that make the whole system to meet user needs. System pressure test ismainly because the system needs work teaching English in schools face relatedpersonnel, the number of users is large, the work required to determine the systemstability and practicality. Test results are given in graphical form, the effect is verysatisfactory.
