摘　　要：如何才能开发出更像人类教师的ICAI(intelligent computer-assisted instruction)系统,对学生个性化的问题进行准确的反馈,对学生的疑难问题进行正确及时的解答,目前还没有一个统一有效的方法。用人工智能技术对虚拟试题库的建立、数字语音合成方法等进行研究,提出四则运算二叉树概念,建立四则运算的结构模型,并形成虚拟题库。开发出行为更像人类教师的ICAI系统,该系统能自主生成四则运算题目,并对学生提出的四则运算问题进行实时回答及语音讲解。There is no general and effective way to develop an intelligent computer-assisted instruction （ICAI） system like a human teacher who can feed back with the student＇s individual question and give them right answer and explanation in time. By using the artificial intelligent technique, the method of setting virtual examination database and composing digital sound were studied. Then, the concept of arithmetic binary tree was proposed to construct arithmetic structural model and to form the virtual examination database. An ICAI system which is like a mankind teacher was developed. This system can create arithmetic subject independently, and answer the question asked by students with digital speech synthesis in time.
