Cai Model With Mechanical Design Web-based Courseware Development

With the development of computer and Internet, CAI gets more and more recognition and gains flying development as a way of a sort of rising educational model. Therefore it has good prospects in future. In this dissertation, the courseware design of CAI (Computer Assisted Instruction) based on Web was introduced and the system scheme and method of realization in technology of the software were also explained. The CAI mode was analyzed deeply. Many problems in teaching can be solved in mechanical design vividly by taking the advantage of multimedia Design method of CAI based on Web and multimedia was researched deeply and used to implement CAI for course of the mechanical design.First, through recounting the history of CAI development and analyzing the existing problems, determined that design method of CAI based on Web and multimedia is important and indispensable. Briefly stated the fundamental and current situation of CAI.Second, from many points of view study the CAI mode, which is influenced by the psychology. Expound how could to make choice and orientation before designing CAI.Third, based on defined function of software, designed the structure of courseware that directed by menu navigation with a link and the modularization structure of system program, then selected appropriate platform and tools.Fourth, based on selecting HTML as the form of courseware, designed the implemental method for mutual controlling in the courseware and a convenient method for courseware making.Fifth, designed the implemental method of multimedia courseware playing and menu navigating courseware content, based on utilizing interface of IE control.Sixth, designed and collected multimedia materials by tool software, such as Flash, 3DMAX and AutoCAD etc. and applied them in this CAI design.Seventh, by utilizing interface of functional ActiveX module control and program design such as VB and ASP, gifted software many strong functions, like as chat, information share, registration in server and terminal connecting.Eighth, through applying the design method of CAI based on Web and multimedia to design of CAI for course of the machine design, implemented function of based on Web and multimedia for CAI.Eventually, reached a conclusion to research content of entire dissertation, pointed out the limitation of design method based on COM (Component Object Model) control and the development orientation.
