Based On HTML5Online Courses Teaching System Design And Implementation

In the current age of the Internet, the network technology, multimedia technology,Internet technology has got rapid development. Bring us is faster network transmission speed,better effect of multimedia playback, more intelligent IT management system. The emergenceof the Internet thinking changed the traditional working mode of enterprise, promote offlinebusiness gradually shift to online. Like this happen in education institutions also changes, thetraditional offline classroom education gradually shift to the network curriculumteaching.Change the way education mode to online and offline.This can not only reduce thelabor cost of enterprise, the classroom leasing costs, can expand business and the source of thenew students channel, enhance the level of enterprise business and improve the managementbenefit of enterprise.In the current Internet technology is the end of the hottest technology development.Afterthe popular B/S architecture, there is still the bottleneck of stress on the server.So the balancethe client and the server pressure has become an important breakthrough performanceimprovement. The rich client technology is put forward in the part on the server side logic tohandle transfer to the client.To solve the B/S architecture of "thin" client and control problemclumsily. At present the most popular front-end technology, the rich client technology isHTML5.Through the combination of HTML and JavaScript to use most of the underlyinglogic to handle is transferred to the client.Only on the server to provide a small amount oflogic processing and data interface. It also with animation, multimedia features comparedwith HTML features, three features, etc., can replace part of the Flash and Silverlight canrealize the function, and has better processing efficiency.So choose HTML5technology asthe network teaching system of the implementation of the scheme.Choose according to demand for the browser’s B/S structure, it shows part of the processinginterface, at the same time using JavaScript, jQuery and CSS3for front-end display and logiccalls. Development framework of MVC and HTML5, realized the function of the modulardevelopment, further improve the development efficiency and improve the efficiency of thesite. The underlying language use high flexibility of Java, Web server is Tomcat, MySQL asthe database management software. Through the education institutions, when conducting research, comprehensive analysisof online and offline education mode form analysis report. According to the analysis ofproject feasibility analysis, network structure design, the overall architecture design,architecture design and work process analysis. Determined by analysis of the relationshipbetween the data entity, complete data logical structure design and table design. Systemimplementation process is divided into administrators, students, teachers and tourists fourtypes of roles.Of those visitors with only the rights of public courses, the administrator has thehighest authority, the teachers and students for the video courses and teaching materials ofpermissions divided according to course category. Through the browser to access on the PC ormobile end network teaching system, teacher’s role can realize functions include personalinformation management, video course upload and update, upload and update the teachingresources, test papers to upload and update, score entry.Students can realize functions includepersonal information management, curriculum learning and download download, teachingresources, school exam and score query.Officer is responsible for the management of allinformation, review the user’s registration, website announcement, comprehensive dispatchingnetwork teaching system as a whole.Future study further the HTML5technology, refined role assignment, realize theconnection with other teaching institutions, to research based on the network teaching systemon mobile.
