Intelligent Computer-assisted Instruction (ICAI): Flexible Learning through Better Student-Computer Interaction
本文介绍智能计算机辅助教学（ICAI）如何利用人工智能技术模拟人类辅导过程，通过模块化知识库和自然语言理解实现灵活交互，并以地理教学系统GEO为例说明其应用。
Intelligent computer-assisted instruction (ICAI) uses artificial intelligence techniques to imitate in computer form the power of human tutorial processes. Its major technical features are the use of a modularized knowledge base instead of CAI's textual scripts, and the ability to interpret the student's statements and questions expressed in natural English. These features make ICAI systems extremely flexible and allow the student much greater learner control of the interaction than is traditionally possible in CAI. Other major elements of an ICAI system are an extensive model of the student and an explicit model of the tutoring process. Our research on the development of GEO, an ICAI system which interacts with students in the area of geography, is briefly described. Finally, the nature of this new technology is discussed in terms of its potential influence on university teaching and learning, especially in terms of our conception of learning.
