Implementation of an Intelligent CAI System Based on a Dialog Recognition Model

为了实现智能化的计算机辅助教学（CAI），研究教学对话框上的智能接口是非常重要的。作者的研究目标是设计一个基于对话识别模型的程序设计实验室支持系统。为了实现这一目标，本研究对以下几个方面进行了研究：（1）计算机专业新生的教学策略，（2）对话协议的分析，（3）教材知识模型的定义，（4）智能CAI的智能界面设计。对话数据收集自千叶工业大学计算机科学系程序设计实验室，其中使用了45个Smalltalk-80工作站。研究了参考模式的对话协议。明确了基于混合优先级模式指导策略的智能接口设计也是必要的。

For the implementation of an intelligent CAI(Computer Assisted Instruction), the investigation of intelligent interfaces on the instructive dialogs is important. The objective of the authors'research is the design of a support system for programming laboratories based on a dialog recognition model. In order to achieve this objective, the investigation on the following projects were carried out : (1)instruction strategy for the freshmen of computer science, (2)analysis of the dialog protocols, (3)definition of the knowledge model for teaching materials, (4)design of intelligent interfaces for the intelligent CAI.To define the instructive models, the analysis of the dialogs between the professors and students is indispensable. Dialog data were collected from the Programming Laboratories in Department of Computer Science at Chiba Institute of Technology, where 45 Smalltalk-80 workstations were utilized. The dialog protocols of reference modes were also studied. It is made clear that the design of the intelligent interfaces based on the instructive strategy for the mixed priority mode is also desired.
