摘要
为了满足教学的需要,在分析了软件系统柔性产生机理的基础上,提出了建立基于柔性CAI平台的思想并给出模型。该模型分为五个层,即:环境支持层、运行平台支持层、物理管理层、映射层和应用层,并具体讨论了每一层的功能和开发方法。该平台提供了三个不同层次的柔性,即:面向开发员级、面向教师级和面向学生级的柔性应用平台。最后,结合物理CAI平台设计实例进行了说明,证明基于柔性的CAI平台适应能力强,使用方便。
In order to meet the need of teaching and learning, the notion and model of designing CAI platform based on flexibility are presented, based on the analysis of mechanism of producing flexibility on software. The model consists of five layers which are environment support layer, running platform support layer, physical management layer, mapping layer, and application layer. Furthermore the functions and designing methods of each layer are discussed. The platform provides flexibility of three different layers which are developer-oriented, teacher-orlented,and student-oriented. FinaLly, the design of physics CAI platform is taken as an example to explain the method of designing CAI platform based on flexibility and the result proves that the platform is of more adaptability and operates easily.
