课件描述语言SDL及其应用

SDL: Scripts Describe Language and the Applying Method of It

计算机辅助教学(CAI)系统设计的一个重要工作,就是课件的计算机化.在现行的CAI系统的设计中,课件大多是和操纵课件进行教学的程序熔合在一起的.这种方法在课件庞大复杂时是难以办到的.既使是一般规模的CAI软件,使用这种方法设计也会造成系统维护上的困难,灵活性较差.

In order to develop a CAI system, we must describe and store then scripts. So a scripts describe language (SDL) is needed. In this paper, we will discuss our SDLhaving been developed and applied to 'ZHU- TI' CAI system.
