项目摘要

We have developed a CAI system described by LISP with information of multimedia. We use VTR, LD and sound board as the media. We studied following 6 subjects of CAI instruction.(1) We studied a method to analyze incorrect answers when students expand numerical formulas and a method to provide suitable informative feedback for incorrect answers in LISP-CAI. We also apply the method to basic probability problems.(2) We developed a new pattern matching routine of numerical formulas and a routine to detect their similarity. The routine has been formalized on the basis of syntax parsing method of programming language, therefore it has considerable flexibility.(3) We developed a utility for pattern matching of Chinese compound words and their simirality based on the relation of them. There is the relation in the dictionary.(4) We have also developed the CAI system described in IC-Lisp (a subset of common LISP) to obtain wide compatibility for many sorts of personal computers and have implemented a courseware with VTR information.(5) We have developed many course wares by the system in the field of probability, information science, physics, electronics, mechanics, chemical science, commercial science and experimental instructions in engineering. We have instructed students by these cours wares with VTR information. The questionnaire shows that most students are satisfied with the system to learn subjects and state the effectiveness of visual information.(6) We have implemented LISP interpreter which is a full set based on the specification of UTI-LISP operated with DOS extender for higher compatibility.

我们开发了一个用LISP语言描述的多媒体信息CAI系统。我们使用VTR、LD和音板作为媒体。我们研究了以下六个CAI教学主题。(1)研究了在LISP-CAI中，学生展开数值公式时的错题分析方法和对错题进行适当信息反馈的方法。我们也将该方法应用于基本概率问题。(2)我们开发了一个新的模式匹配例程的数值公式和例程来检测它们的相似性。该例程是基于程序设计语言的语法分析方法形式化的，因此具有很大的灵活性。(3)本文根据汉语复合词与相似词之间的关系，开发了一个汉语复合词与相似词的模式匹配工具。字典里有关系。(4)我们还开发了用IC-Lisp语言描述的CAI系统，以获得对多种个人计算机的广泛兼容性，并实现了带有VTR信息的课件。(5)利用该系统开发了概率论、信息科学、物理学、电子学、机械学、化学、商科、工程实验教学等多个学科的课件。我们已经指导学生通过这些课件与录像机信息。问卷调查显示，大部分学生对系统学习科目及陈述视觉信息的有效性表示满意。(6)为了提高兼容性，我们实现了一套完整的基于UTI-LISP规范的LISP解释器，并与DOS扩展器一起运行。
