基于双网传输的多媒体CAI课件设计策略

On strategy of design of multimedia CAI courseware based on CATV network and telecom network broadcasting

针对电信网具有交互性却带宽不足、有线电视网能实时传输数据流却缺乏交互功能的特点，提出网络教学的多媒体CAI课件应由双网传输，即：视、音频信息由CATV网传输，电子课件由电信网传输。并对基于双网传输的多媒体CAI课件在理论基础、类型选择、课件结构、导航措施等方面的设计策略上进行了深入探讨。最后简要介绍网络CAI课件的开发步骤。

The computer network in China depends mainly on CATV Network or Telecom Network. This paper aims mainly at the broadcasting problems existed in CATV Network or Telecom Network, a design idea of multi-media CAI courseware based on CATV Network and Telecom Network broadcasting. It makes deeply probe into the theoretical basic, typical selection, courseware construction and piloting method, briefly describes developmental procedure on the design of multimedia CAI network courseware.
