控讨基于教学过程的ITS系统模型

计算机智能导师系统（ＩＴＳ），是智能化教学的一个分支。围绕教师在常规教学过程中所起的作用，分析研究了教师在教学的各个阶段中所承担的角色和完成的工作，并根据教学过程的动态特性，提出了一个基于教学过程的ＩＴＳ模型。还针对ＩＴＳ模型中的学科知识库、学生模型和教学策略推理机的实现方法给出了描述。

A Discussion of the Intelligent Tutor System Based on the Teaching Process

The computer intelligent Tutor System (ITS) is a branch Of the intelligent educahon. In this paper, we provided an ITS model which is based on the teaching process. First, we divided the teaching process into several dynamic stages, and study the teacher's role and functions in different stages. Then, we discuss several parts of the ITS model. the knowledge base, the student model and the inference engine of teaching. Finally, we give a kind of arithmetic of the inference strategy, which can teach students in accordance of their learning ability in gradual manner.
