The Development and Application of Multimedia Courseware

With its quick development and high popularity,multimedia technology,including words,graphics,voices,cartoon and so on,has been widely used in the teaching fields.CAI,Computer Assisted Instruction,which is a new method of computer assisted teaching,achieves the teaching purposes by interaction between computer and students.It is quite a different from the traditional teaching methods,which is one of ways of combination between computer technology and class teaching.Multimedia courseware is an important teaching method.According to teachers' designs,it is a modern teaching technology,centered by computer,using the digital processing and audio system,of achieving the purpose of teaching material's store,transmission,conversion,searchers by combinations of words,voices,pictures and many other multimedia information.People pay more and more attention to the technology because it is convenient to teaching by realization of interactive control between person and computer through the combination of words,pictures,voices and graphics.
