多模式智能教学系统的教学模式调度研究

Instruction Pattern Scheduling in Multi-Instruction-Pattern ITS

针对目前多模式智能教学系统中存在的两个问题(教学模式由于要承担所有的教学规划任务而负担过重问题,教学模式之间过渡问题),提出将教学规划进行分层处理的"全局教学规划—教学模式调度—模式内局部教学规划"的解决模式.这种解决模式的关键问题就是教学模式调度问题.阐述了用不确定推理方法为学生选择合适教学模式的方法,并设计出教学模式的调度算法.实验说明这种解决方案能取得令人满意的效果.

There exist some problems in existed multi-instruction-pattern ITS, such as the overburden on instruction pattern and the stiff transit from one instruction pattern to another. A method is proposed to solve these two problems. That is, the instruction plan is processed in two layers by the mode of 'global instruction planning—pattern scheduling—the local instruction planning in instruction patterns'. It is focused on how to select the suitable instruction pattern for student, and the method of uncertain reasoning is used to select instruction pattern that is suitable for student well, and the algorithm of instruction pattern scheduling is designed. At last the experiment presents that this method is satisfying.
