摘要: 引入了通用转换网络对多媒体课件的教学流程作了形式化描述,并在此基础上讨论了教学流程及教学呈现在多媒体课件写作系统中的内部表示方法.该方法将课件中的教学流程描述和教学呈现的表示相分离,使课件写作系统更加灵活;其次,引入呈现描述来表示教学呈现内容,实现了教学内容的并发呈现.本文同时给出了相应表示方法实现的内部结构.

Abstract: The Key problem of developing multimedia courseware authoring system is how to present the instruction flow and presentation.GNT(Generalized Transition Network) is used to describe instruction flow and instruction content is expressed by PC(Presentation Context)in multimedia courseware.In the meantime,how to use them in BUAA-MCAS(BUAA Multimedia Courseware Authoring System) is discussed. It includes how to describe instruction flow with GTN and how to present instruction contents with presentation context.The internal data structure is also given.These methods in BUAA-MCAS have two characteristics.First,the description of instruction flow and presentation of instruction contents are separated,which makes the courseware authoring system flexible.Secondly,instruction contents can be concurrently presented by expressing the instruction presentation with presentation contexts.
